What Are the Advantages and Disadvantages of Solar Energy?

In the race to reach net-zero emissions, countries around the world are looking to scale up and eventually depend on renewable energy to substitute polluting fossil fuels. Solar is the most abundant, fastest, and cheapest energy source on Earth, and it generates minimal greenhouse gas emissions. Although this renewable energy is rapidly growing across the globe, with an increasing number of countries investing in it, there are some factors that could hinder its growth. What are the main advantages and disadvantages of solar energy and how does this valuable renewable resource work and w?

What Is Solar Energy and How Does It Work?

The vital role in which the sun plays in life on Earth has been celebrated since ancient times. Egyptians in Africa were the first people known to use solar energy on a large scale to heat their homes, designating them in a way that could store up the sun’s heat during the day and release it at night. Fast forward to today, societies around the world have developed innovative technologies that allow us to turn the sun’s energy into electricity that powers heating and cooling systems, transportation, lighting, and ventilation, just to name a few. 

This energy source is growing fast: between 2010 and 2019, solar rose from 0.06% to 1.11% of the global energy mix. In 2020, it recorded a record growth of 22% as installations experienced a boom. Among the countries that have poured the most money into solar energy are China – by far the largest investor, the United States, Japan, Australia, and India. The latter aims to be a global leader in solar energy, with Prime Minister Narendra Modi committing to increase energy from renewable sources up to 50% by the end of 2030 . In Europe, Spain is one of the first countries to deploy large-scale solar photovoltaics and the largest producer of solar-powered electricity on the continent. 

Before we move on to some of the advantages and disadvantages of solar, it is worth answering a question: how does solar energy work? 

When sunlight strikes the Earth’s surface, human-made innovative technologies capture their light and heat and convert these into electrical energy. This conversion happens through photovoltaic (PV) panels, which contain cells that can capture the sunlight’s energy. This energy generates electrical charges that move around the cell, causing electricity to flow. An alternative to PV is solar thermal panels: as opposed to PV generating electricity, thermal panels create heat. When installed on a roof facing the sun, they capture the hot sun rays which are used to heat water stored in a cylinder.  

While many nations are starting to recognise the vast potential of solar energy – a powerful and extremely beneficial renewable source – there are still some downsides to it. We explore the main advantages and disadvantages of solar energy.

5 Advantages of Solar Energy

1. solar is a renewable energy source.

As the name suggests, solar power is a resource that never runs out. Unlike fossil fuels, the production of which requires huge efforts, time, and expensive heavy machinery, renewables convert a natural resource – in the case of solar power, sunlight – directly into electricity. Another big factor that makes renewable energy much more attractive than coal, oil, and natural gas is the significant difference in emissions, namely fossi fuels being one of the world’s largest contributors to the generation of greenhouse gases. Renewable energy sources are not only cleaner but also cheaper and easier to produce than any fossil fuel. But what makes solar energy particularly advantageous over other sources of renewable energy?

2. Solar Energy is Immensely Abundant

In fact, solar is the most abundant energy source on the planet and throughout the years, we managed to develop innovative technologies that could allow us to depend entirely on solar for the rest of our existence. Another huge advantage is that just a tiny fraction of the sunlight we get every day can provide a huge amount of energy. Indeed, the US Department of Energy argues that an hour and a half of sunlight that reaches the planet’s surface generates enough power to meet all of humanity’s energy consumption for an entire year.

3. Solar Technologies Are Getting More Efficient

Over the years, scientists have made some important advances in the development of solar technologies, notably improving the efficiency of solar panels and battery storage systems as well as their overall durability over time. According to Rhone Resch , President of the Solar Energy Industries Association (SEIA), the global PV sector has been growing at an average of over 40% in the last eight years and major advances in automation, manufacturing, and throughput have considerably improved this technology. Most panels today are between 15% and 20% efficient , meaning that they are able to convert 15% to 20% of the amount of sunlight they absorb into electricity. Panels’ efficiency has improved consistently over the past decade, a promising factor and one that contributes to continued cost reduction. Furthermore, their resistance to extreme weather has been drastically improved, bringing their average durability to about three decades with little to no loss in efficiency. 

Improvements have also been made in battery storage systems , which are emerging as a key solution to effectively integrate solar renewables in global power systems on a large scale. Most of the world’s utility-scale storage systems are being deployed in Australia, Germany, Japan, the United Kingdom, and the United States. Small islands and off-grid communities have invested in large-scale battery storage systems to store excess energy. However, an increasing number of small-scale batteries are also being produced and they are expected to complement utility-scale applications by 2030.   

4. Solar Panels Are Getting Cheaper

In the list of the advantages of solar energy, price is an important point. In its World Energy Outlook 2020 report, the International Energy Agency (IEA) confirmed that solar power schemes now offer the cheapest electricity in history. In its 2021 report, the Agency predicted that by 2050, renewable energy generation will keep growing, with solar power production skyrocketing and becoming the world’s primary source of electricity . Solar energy is indeed praised for the relatively marginal operation and maintenance costs of panels. While the cost of panels itself is the most critical part of the overall equation, solar is definitely a cheap source of power that can considerably lower the electricity bill in the long run. 

5. Solar Life Cycle Generates Minimal Greenhouse Gas Emissions 

Lastly, solar energy generation’s minimal contribution to global greenhouse gas emissions is one of the main benefits of this renewable energy source. Indeed, solar power produces no emissions during generation itself and studies demonstrate that it has a considerably smaller carbon footprint than fossil fuels over its life cycle. Even though PV modules and other components are made of materials that are mined and processed and thus generate some levels of emissions, solar is still undoubtedly a carbon-smart energy source whose lifetime emissions are insignificant when compared to coal and natural gas. In fact, a coal power plant releases on average 25 times more emissions than the ones produced by a solar power system. Similarly, a natural gas power plant, despite being less polluting than coal, still generates 10 times the amount of emissions generated by a solar array.

3 Disadvantages of Solar Energy

1. solar energy is still expensive for households.

Did we not just say that solar energy is getting cheaper? Well, it is true. However, there are some aspects of solar technology that are still quite expensive. Indeed, purchasing a solar system requires a significant initial investment to cover the costs of panels, inverter, batteries, wiring, and the installation of the system itself. One of the most expensive parts of the system is the batteries used for solar power storage, which can cost upwards of USD$5,000. When solar energy started being commercialised 40 years ago, the price of panels was also incredibly high. Nevertheless, solar technologies are constantly developing and this is contributing to a significant decrease in prices. Statistics show that the average global cost of solar PV modules has gone down drastically in the first two decades of commercial solar power production and it has been slowly but consistently decreasing ever since. Just a decade ago, an average 6-kilowatt hour residential solar system could cost USD$50,000 or more. However, the price has gone down by an annual average of 62% and nowadays, a typical home installation rarely exceeds UDS$20,000. 

2. Solar Energy is Weather Dependent  

An undoubted disadvantage of solar energy is that this technology is not equally efficient around the world. While solar power can be generated on a cloudy day, some level of daylight is still required in order to harness the sun’s energy, and the amount of energy that can be produced varies greatly depending on many factors, such as the amount and quality of direct sunlight that the panels receive as well as the size, number, and locations of the panels themselves. Thus, in countries that receive limited sunlight throughout the year, alternative renewable resources like geothermal energy and hydropower might work better. In Iceland, an area with little sunlight and wind, for example, these two energy sources make up 27% and 73% respectively, allowing the country to generate 100% of its energy from renewables . 

3. Solar Power Plants Are Not the Most Environmentally Friendly Option

As we said before, the carbon footprint of solar energy is minimal. However, this renewable still has some aspects, mainly related to land use and waste generation, that can still harm the environment. First and foremost, solar power plants require space. For example, a solar power plant to provide electricity for 1,000 homes would require 32 acres of land . This means that, in order to meet the US energy consumption needs, nearly 19 million acres, equivalent to 0.8% of the entire country, would be necessary. 

Another factor to consider is the management and disposal of hazardous materials such as metals and glass needed to build some components of solar infrastructure that are energy-intensive to produce and thus responsible for the generation of carbon emissions. Building PV cells and panels also requires some hazardous chemicals and heavy metals. To avoid harming the environment, such materials necessitate careful management and disposal procedures once the solar plant’s life comes to an end. The International Renewable Energy Agency (IRENA) projects that by 2050, solar energy systems could be responsible for up to 78 million tonnes of waste. 

Should We Still Invest in Solar Energy? 

The short answer is yes. There is no such thing as a ‘perfect’ energy source. From nuclear and fossil fuels to renewable resources, all of them have many advantages but also some disadvantages, solar energy included. However, as we are quickly running out of time in the race to reach zero emissions, it is crucial that all countries begin to seriously evaluate which sources of energy can bring the most benefits. While solar energy might not be the best solution for northern countries for the lack of sunlight they receive throughout the year, and some of its disadvantages such as the extensive land use that the installation of solar panels requires might not make it the best candidate for everyone, this renewable resource, along with all others, certainly has undeniable potential and it still a better alternative to environmentally unfriendly fossil fuels, beyond being the best chance we have at stopping global warming.

For most homeowners, going solar is a no-brainer. It lowers your electric bills and reduces your carbon footprint. It will often boost your home value and can protect you from blackouts when you pair solar panels with an energy storage system. If you finance your solar panel installation with a zero-down loan, you can even start saving right away. 

But like most things in life, solar energy isn't perfect. If your roof faces north or it's angled too steeply, you probably shouldn't get solar panels. If you're about to move, you likely won't save enough to fully recover the upfront costs. And because solar panels require sunlight, they don't work at night.

Before you take the plunge, we'll help you decide if solar is worth it for your home.

Key Takeaways

Rooftop solar panels aren't the perfect fit for everyone , but that's okay. Like any other home electrification product, solar panels provide clear benefits to homeowners needing energy upgrades and electricity bill reduction.

The pros of solar outweigh the cons in most situations . For most solar shoppers, savings on energy bills make solar worth it.

Solar panels can add home value and protect against rising energy costs .

Advantages and disadvantages of solar energy

Whether you want to raise your home value, reduce your carbon footprint, or combat rising electricity costs, going solar is a great choice. A solar panel system provides energy independence and will often pay for itself in electricity bill savings. Incentives like the federal tax credit also help reduce your up-front cost and increase your return on investment.

On the other hand, solar energy doesn't work for every roof, it's not ideal if you're about to move, the upfront cost can be expensive, and finding a local installer can sometimes be difficult.

Here are the primary pros and cons of solar energy you should weigh before deciding if it's right for you:

Top pros and cons of solar energy

The advantages of solar energy: Why solar's worth it for most homeowners

You can reap many benefits by installing a solar panel system at your home or business:

1. Solar drastically reduces, or even eliminates your electric bills

The top benefit of solar panels is pretty straightforward. When you install solar panels at your home, you generate your own electricity, become less reliant on your electric utility, and reduce your monthly electricity bill. A solar panel system typically has a 25- to 35-year lifespan, meaning you can cut your electricity costs for decades by going solar.

Most homeowners will save $25,000 to over $110,000 over 25 years with solar.

2. Solar often increases your home value

Many homeowners are interested in solar panels but don't understand how they will impact their homes. Recent studies indicate that installing a solar system can increase your home's value by about 4% . Even if you're not in your forever home, you could earn back your solar panel investment and then some when you sell your house. Whether you've been there for years or just moved into a new home, installing solar is a good investment for most homeowners.

3. Solar reduces carbon emissions

When you go solar, you lower your contribution to climate change. Solar is a renewable source of clean energy that helps reduce carbon dioxide and other greenhouse gas emissions. Unlike traditional fossil fuels like coal, oil, and natural gas, solar energy doesn't directly release pollutants into the atmosphere and water supply. Even compared to nuclear energy, solar comes out on top in terms of environmental impact.

4. Solar protects against rising energy costs

As long as you buy, rather than lease, your solar panel system, you'll lock in electricity costs for the next 25+ years. Once you recover the initial cost of your system in bill savings, you'll generate your own electricity for free. With the federal solar tax credit , you'll also get back 30% of your equipment and installation costs as a credit toward your federal tax bill.

5. SRECs: You can sometimes earn money with solar

In some states, solar panels can turn a profit in addition to generating bill savings that pay off the cost of the system. Solar renewable energy credits (SRECs) compensate you for the electricity that your solar panel system generates. If you live in a state where this incentive applies, you can expect both immediate and long-term returns from your solar investment.

6. Solar works well in most environments

Some alternative energy, like wind and hydroelectric power, need wide open spaces with ample wind changes and large water sources. Solar is a source of energy that can work in almost every environment. While output is lower on cloudy days or in climates without as much regular sun exposure, solar panels still make sense in most climates.

7. Net metering: Your utility "buys" excess solar power

Depending on where you live, you could be eligible for a solar incentive called net metering . With net metering, you can use the electric grid to "store" excess energy that your solar panel system produces. As you send this energy to the grid, your utility company will net it against any electricity you pull from the grid at night or when the sun isn't shining. Essentially, you get to "sell" this excess energy to your utility company in exchange for reduced utility bills. You get more energy independence without going completely off-grid.

8. Solar panels typically require very little maintenance

As long as you choose a quality solar company to properly install your solar panels, they should require very little maintenance compared to other forms of energy production. With no moving parts, your panels might only need an occasional cleaning after snow or inclement weather.

Disadvantages of solar energy: Things to double-check before going solar

Solar isn't perfect. You'll want to understand solar's disadvantages before deciding if it's right for you:

1. Solar panels don't work for every roof

If you have a south-facing roof sloped between 15 to 40 degrees, you're in great shape for solar. Even with an east- or west-facing roof, or one that's flat , solar's likely still worth it. If you can only install solar panels on the north side of your roof, we don't recommend it.

Similarly, solar works well with asphalt shingle or metal roofs. But certain roofing materials used in older or historical homes, such as slate or cedar tiles, can be challenging for solar installers to work with. Some homes have skylights or rooftop additions like roof decks, which can also make installing solar too expensive or difficult.

If your home doesn't qualify for a rooftop solar installation, you still have options. If you have enough open space, you can install ground-mounted solar panels , or if your state has open projects, you can subscribe to a local community solar farm .

2. Solar isn't ideal if you're about to move

It takes time to break even on a solar panel system: The average solar panel payback period in the U.S. is around eight years. Even though going solar will likely increase your home's value, if you plan to move in the next three years or so, it's probably not worth it.

3. If your electricity costs are low, your solar savings will be too

The ultimate benefit of solar energy is that it saves you money every month. If you live in a state like Louisiana, though, where the cost of electricity is often 30% lower than the national average , it will take a long time to save with solar. On the other hand, installing a solar panel system in Hawaii makes a lot of sense: Electricity costs more than double the national average!

4. If you can't access financing, up-front solar costs can be intimidating

Your upfront cost of solar depends on tax credits, rebates, and the terms of your financing. If you don't qualify for a zero-down solar loan , the disadvantage of solar energy here is clear: Not everyone has the cash to purchase solar upfront.

Several solar financing options can help, such as state-backed loan programs, leases , and power purchase agreements . To understand what solar will cost you, get a quick estimate of the average cost of solar in your state or even a personalized estimate for your home .

5. Solar panels don't work at night

Solar panels require sunlight to produce energy. At night or during inclement weather, you'll need to pull electricity from the grid. If you live in a state with net metering, this isn't a big deal. But if your utility won't compensate you for the excess electricity you send to the grid, you'll need a battery for solar to be worth it.

By pairing your solar energy system with energy storage , you can store excess electricity in your battery. At night, you can pull electricity directly from your battery instead of the grid. While batteries increase the cost of your system quite a bit, they're well worth it in states like California that don't have net metering.

6. Solar panels are sometimes made with toxic materials

Solar panels are made up of silicon solar cells, a metal frame, and a glass sheet . But depending on the brand and model, they can also contain toxic heavy metals like lead and cadmium. While some solar panel manufacturers are starting to phase out these heavy metals, the EPA considers most old solar panels hazardous, so you need to dispose of them properly.

If sustainable solar panels are important to you, make sure to let your installer know so they only include models without heavy metals in your quotes. These panels may cost a bit more, but they are better for the environment.

7. Finding quality solar installers can seem difficult

Many homeowners associate solar panels with pushy door-to-door solar sales reps. Solar is one of the fastest-growing markets in the world, and plenty of companies use aggressive sales tactics. As a result, shopping for solar can feel stressful and confusing.

Today, there are easier ways to shop for solar that put you in control. The EnergySage Marketplace is a free online comparison-shopping platform that allows you to compare solar quotes from vetted installers in your area.

So are solar panels worth it?

Going solar is worth it for most homeowners with eligible properties. It reduces greenhouse gas emissions and saves you considerable money on your electric bills.

As you consider investing in solar energy, though, make sure to weigh the pros and cons as they relate to your home, geography and climate, and unique needs. If your roof isn't a good fit, you plan to move soon, or your electricity costs are already low, you may want to hold off on installing solar panels.

Solar Energy: Benefits and Drawbacks

Katrina Ávila Munichiello is an experienced editor, writer, fact-checker, and proofreader with more than fourteen years of experience working with print and online publications.

With the growing threat of climate change due to the excessive release of carbon emissions, many nations are looking to clean energy alternatives to replace traditional fossil fuels .

Of all the clean energy alternatives, solar has arguably been the most expensive though prices have been declining. However, after considering the pros and cons along with the expectation that prices will continue to decline , the future of solar energy is looking rather bright.  

The pros of solar energy include that it is a sustainable alternative to fossil fuels and has a low impact on the environment and the potential for any country to produce it. The cons are that it only produces energy when the sun is shining, needs a significant amount of land, and that certain solar technologies require rare materials.

Key Takeaways

• Solar energy is becoming an increasingly cost-competitive alternative to fossil fuels.
• Solar energy is a sustainable energy source, has a low environmental impact, and promotes energy independence.
• On the other hand, it is limited by how long the sun is out, may cause a scarcity of materials, and contains hazardous materials similar to electronics.
• Pricey disadvantages of solar energy may be rendered negligible by technological advances that increase efficiency and storage capacity.
• Increasing the incentives for the development of solar energy may be worthwhile.

Sustainability

The advantage of solar energy is that it is a sustainable alternative to fossil fuels. While fossil fuels have an expiration date that may be fast approaching, the sun is likely to be around for at least a few billion years.

Low Environmental Impact

Solar energy has a substantially reduced impact on the environment compared to fossil fuels. Its greenhouse gas emissions are inconsequential as the technology does not require any fuel combustion. Also, although concentrating solar thermal plants (CSP) are comparatively inefficient in their water usage depending on the type of technology being used, the right technology significantly increases efficiency while photovoltaic (PV) solar cells do not require any water when generating electricity.  

Solar energy technology is becoming an increasingly cost-competitive alternative to fossil fuels, though it remains somewhat expensive in certain markets.

Energy Independence

Since the sun shines across the globe, it makes every country a potential energy producer, thus allowing for greater energy independence and security. Solar energy doesn’t only promise to bring security and independence at the national level; solar panels can be installed on individual homes, providing power that does not depend on being connected to a larger electrical grid.

Intermittency

One of the biggest problems that solar energy technology poses is that energy is only generated while the sun is shining. That means nighttime and overcast days can interrupt the supply. The shortage created by this interruption would not be a problem if there were low-cost ways of storing energy as extremely sunny periods can actually generate excess capacity. As the global capacity for solar power continues to rise, nations like Japan and other global leaders in solar energy technology are focusing on developing adequate energy storage to deal with this issue.

Another concern is that solar energy may take up a significant amount of land and cause land degradation or habitat loss for wildlife. While solar PV systems can be fixed to already existing structures, larger utility-scale PV systems may require up to 3.5 to 10 acres per megawatt and CSP facilities require anywhere from 4 to 16.5 acres per megawatt. However, the impact can be reduced by placing facilities in low-quality areas or along existing transportation and transmission corridors.

Scarcity of Materials

Certain solar technologies require rare materials in their production. This, however, is primarily a problem for PV technology rather than CSP technology. Also, it is not so much a lack of known reserves as much as it is the inability of current production to meet future demand: Many of the rare materials are byproducts of other processes rather than the focus of targeted mining efforts. Recycling PV material and advances in nanotechnology that increase solar-cell efficiency could both help boost supply , but perhaps finding material substitutes that exist in greater abundance could play a role.

An Environmental Downside

The one environmental downside to solar technology is that it contains many of the same hazardous materials as electronics. As solar becomes a more popular energy source, the problem of disposing the hazardous waste becomes an additional challenge. However, assuming the challenge of proper disposal is met, the reduced greenhouse gas emissions that solar energy offers make it an attractive alternative to fossil fuels.

Lower impact on environment

Helps countries become more energy independent

Cost-effective

Occupies large amount of land

Technology not yet widely available

Can still create some harm to environment

The approximate number of terawatts of solar energy that shine on the Earth each day—10,000 times the daily global energy use.

The largest solar energy plant in the entire world is located in Rajasthan, India. The Bhadla Solar Park, which was completed in April 2020, boasts some impressive statistics. The plant occupies 10,000 acres and has an installed capacity of 2,245 megawatts. The total investment in the project is estimated to be around $1.4 billion.

The largest solar park in the United States is known as the Solar Star park near Rosamond, California. The power station consists of two separate installations named Solar Star-1 and Solar Star-2, with respective capacities of 314MW and 265MW. Like the plant in India, the location was selected due to its large exposure to the sun and minimal rain.

Both wind and solar energy are two of the fastest-growing sources of renewable energy . Both energy sources help to cut down pollution and offer alternatives to fossil fuels, however, there are notable differences between the two.

The turbines that power wind energy are less harmful to the environment than solar panels. Furthermore, they produce more electricity than solar panels and can be installed offshore. Unlike solar, wind energy can be harnessed both day and night. However, wind is an unpredictable energy source. Turbines are also quite noisy, and, like solar panels, require a lot of land space thus don't make sense for densely populated areas.

Ultimately, solar panels are the more powerful and predictable source of energy. They require less space, are less noisy, and can be installed on rooftops, etc. in densely populated areas.

What Are the Pros and Cons of Using Solar Energy for Your Home?

Using solar energy for your home will save you money, increase your home value, help you become energy independent, and will decrease your carbon footprint. However, the large solar panels may alienate potential buyers. Furthermore, some HOA agreements may not allow you to install solar panels on your home.

Do Solar Panels Increase Your Property Taxes?

Because installing solar panels increase the value of your home, they can also increase your property taxes. However, many states offer exemptions for residents. Check your county clerk's website for the most accurate, up-to-date information.

Solar energy is electrical or thermal energy harvested from sunlight. Solar panels contain photovoltaic (PV) cells made up of semiconductor materials (such as silicon) to absorb elemental particles from the sun called photons. When absorbed by the panel, the photons release electrons from the atoms of the semiconductor material and the flow of these electrons within the cell creates an electric current we can direct to our circuits.

Solar panels can be placed anywhere with an abundance of sunlight, such as open fields or rooftops. The more light the panels sit exposed to, the more electricity production potential.

The sun’s constant barrage of energy in the form of photons can be collected, transformed and used to power our world—but for you, the question may be more about cost-effectiveness. Is solar efficient enough to power your home or business? Below are the pros and cons of this process and what solar’s availability and cost mean for consumers.

For the average consumer, there are many pros and cons of using solar energy in your home or business. Whether your concerns are with saving money on your bills, helping the environment, or becoming energy-independent, here’s a list of advantages and disadvantages that should be of concern to you.

Renewable Energy Source

Fossil fuel remains a resource in declining supply that, when burned to create energy, releases harmful byproducts into our atmosphere. Solar power has the potential to help us minimize our use of fossil fuels and the impact we have on the environment.

Reduces Electric Bill

Solar energy can help most consumers power their homes as an alternative or supplement to purchasing electricity from a grid. With power prices on the rise, consumers stand to save a considerable amount on monthly power bills by switching to solar.

Energy Independence

A home reliant entirely on solar power features the capacity to function entirely off-grid, especially when supplemented with a solar battery system to maintain power during non-daylight hours. These battery systems can also turn solar systems into emergency backups during power outages.

Solar Panels Increase Home Values

According to the National Renewable Energy Laboratory , every dollar a solar panel saves you on your electrical bills increases the value of your home by $20 . Also , homes with solar panels sell for four percent higher than those without them. If a home has solar panels, its owners will be saving money in the long run, increasing its appeal and value.

Long-Term Savings

The start-up costs for a solar system represent a significant expense, but the costs are usually mitigated by savings on the electric bill. Consumers can often break even on the investment—usually within six to 10 years—and then start reaping the benefits well before the system needs replacement or considerable maintenance.

Low-Maintenance Costs

Once installed, a solar system requires little maintenance as long as it remains unaffected by environmental factors. If panels are kept clean and free of debris, they should continue to function without any additional action by the consumer for many years. 

Regarding maintenance, professional service for your panels can cost between $140 to $180 , while an annual inspection or cleaning can cost about $150 . However, solar panel warranties typically cover them with performance guarantees.

Benefits the Community

A process known as net metering allows consumers to sell excess electricity their panels produce back to the utility company, further reducing utility bills. This often reduces a community’s reliance on fossil fuels, as well.

Diverse Uses

Solar energy is extremely versatile, and can provide power not only to our homes and appliances but to places where channeling power from a grid is impractical or impossible, such as remote, off-grid regions, satellites and boats.

Rising Power Prices

The price of electricity has been on the rise for the past ten years and remains unlikely to decrease in the near future. Solar power can help the consumer keep bills low and with net metering, many consumers can even sell extra energy back to the utility company to turn rising electricity prices to their advantage.

High Cost of Solar Panels

Despite decreases in the cost of solar panels over the past ten years, a complete solar installation still requires significant investment. On average, a consumer can expect to pay around $18,000 on a complete solar setup for a home before accounting for any incentives and the federal solar tax credit .

Sunlight Dependent

Without sunlight, a system reliant on solar energy cannot produce power. This can pose a problem for consumers in areas with less-than-ideal levels of sun exposure or poor weather. Solar batteries to store excess energy can help mitigate this issue and even under constant-clouds the best solar panels will still remain cost and energy efficient enough to be worth the installation.

Installation Can Be Difficult

Although most of the components in installing solar panels are relatively simple, if you’re not a fan of being on a roof or not comfortable working with electricity, solar panel installation can be complicated. For instance, tying the panel wiring into the home can be complex for the average DIYer and should be left to the professionals.

Space Constraints

Solar panels and the associated wiring take up space. Depending on the number of solar panels needed , finding enough space with adequate exposure can be difficult, especially in less-spacious residential areas.

Solar Energy Storage Is Expensive

Since solar batteries store the excess energy generated by your solar panels, they are essential to your solar panel system. However, they can be costly depending on the type and size of the battery. For instance, a single lead-acid battery can cost between  $200 and $800 , while a   residential lithium-ion solar system can cost  $7,000 to $14,000 .

Environmental Impact of Manufacturing

The production of solar technology has its environmental downsides, as the mining of materials and manufacturing of solar panels creates a considerable amount of greenhouse gas. The Office of Energy Efficiency & Renewable Energy issued a report revealing that solar panels pay for themselves in terms of greenhouse gas emissions within one to four years of use, so while certainly still a downside, much of the issue can be mitigated.

Difficulty With Relocation

Uninstalling a solar system and moving it can be difficult, time-consuming and expensive, so the semi-permanence of the structures means panels are not often something you’ll take with you from house to house. They’re often best considered an investment in the structure or property they’re added to.

Scarcity of Materials

Sunlight may be unlimited, but the materials required to manufacture solar technology are not. The availability of the raw materials required to produce solar products may not be sufficient to meet future demand and the options for mining these materials can have a significant environmental impact.

Disposal or Recycling Options

Solar technology contains some of the same environmentally-harmful substances in many consumer and industrial electronics, so proper disposal is critical. At present, recycling options for solar panels remain limited.

Solar energy certainly remains more sustainable than fossil fuels, which are limited in supply and release harmful greenhouse gasses into the atmosphere when burned. The limiting factor in the sustainability of solar energy overall primarily comes from a scarcity in the raw materials required to produce solar technology, the greenhouse gasses emitted during manufacturing, and the impact of panel disposal on the environment.

The use of solar power in lieu of grid power, however, offsets the emissions and carbon footprint of production within four years of use. Additionally, solar panels are ultimately recyclable, as they’re made from glass, metal and silicon. At present, we lack adequate infrastructure to collect and facilitate the recycling process on a large scale.

Free, No-commitment Estimates

Typically, yes, solar energy is worth the cost . But whether or not it’s right for you depends on many variables you’ll need to investigate for yourself, including your location, tax rebates and incentives and net metering availability among others. While pros of solar energy significantly outweigh cons, the feasibility of a solar venture will vary based on the consumer’s financial means, living situation and space constraints.

Bottom Line

The pros of solar energy considerably outweigh the cons. It may take several years, but purchasing and installing a solar system can eventually result in major savings on electricity for the consumer in addition to benefits for our environment.

The sun is a powerful force, one of Earth’s most reliable and plentiful energy sources. As a result, solar energy is experiencing a remarkable surge in growth, and it is expected to remain a prominent player in the energy landscape for the foreseeable future.

In the past few years, solar power has been steadily increasing in popularity, which is expected to continue. This exponential growth is driven by several key factors, including the reduction in the cost of solar panels, which has made harnessing the sun’s power more affordable than ever. Additionally, advancements in solar technology have increased its efficiency, making solar energy systems even more attractive to both residential and commercial owners. This combination of cost-effectiveness and efficiency will certainly drive the continued adoption of solar energy across the United States.

What are the advantages of solar panels?

Aside from significantly reducing your electricity bill, there are certainly a few advantages to installing solar panels, such as reducing your carbon footprint, preparing your home for grid outages and improving the value of your home.

How long do solar panels last?

The average solar panel should maintain peak performance for about 25-30 years. After this time a solar panel can still produce electricity but may experience a decline in efficiency and energy production.

Do solar panels work in the rain?

Yes, solar panels will continue to work in the rain, but production may not be as high as on sunny days. Solar panels can still produce at least 30 to 50% of maximum output during cloudy weather and about 10-20% of maximum output if it’s raining heavily. The use of solar batteries can provide backup power during rainy days for those relying completely on solar.

Do solar panels work in the winter?

Yes, solar panels will continue to work in the winter. Cold weather itself will not impact the efficiency of solar panels, but other factors such as accumulated snowfall and shorter days can decrease the amount of energy produced by the panels throughout the day.

Solar Energy Advantages and Disadvantages vs. Other Renewables

Alternative “green” energy is on the rise everywhere across the world, and solar power’s share of the green market is growing rapidly in many countries just as it is in the United States. For those who have not yet adopted solar energy, the balance between solar energy advantages and disadvantages  is apparently still a critical factor to be weighed before switching.

Sustainable development is now at the forefront of social and political agendas. From the huge international development projects financed by the World Bank and the International Monetary Fund to more local development underwritten by your regional banks, it’s doubtful that funding is even available to projects without a sustainable energy plan.

We, as modern citizens need to compare the advantages and disadvantages of many renewable power sources like bioenergy and geothermal energy, hydroelectricity, wind, and solar energy before settling on the final choice. It’s a question of what fits our needs best and under what conditions.

Solar energy is here to stay, and it has changed the power industry, its business model, and the way electricity is delivered to the grid. Once, the words “public utility” or “power company” conjured images of giant monolithic public or private corporations that owned huge power plants with tall smoky chimneys or cooling towers of reactors. Today, the monolith is gone.

Over the last decade, power companies have divested themselves of their generating capacity and have morphed into “line owners,” buying power generation from the lowest bidder—even from their former generators. This has happened in more than 50% of all power markets across the United States, and solar power made it happen.

Everyone recognizes the glistening panels on rooftops or the arrays covering someone’s backyard. These are common enough sights. But that’s only part of what is driving the industry and the world to greener living. Ranging from 50–25,000 megawatts (MW), large-scale commercial solar producers are providing  an alternative to conventional generation across the country to create new options for people to “go solar.”

Solar energy has taken the lead in overall green energy sources. There are many advantages of solar energy . Among these are its accessibility to most homeowners and, today, to millions of citizens who don’t own their own homes as well, and its increasing affordability. The cost of purchase and installation continues to fall, and there are new contracts in the marketplace, as providers offer lease-to-buy options  while still offering energy below the prices offered by conventional utilities. The times are changing, and solar power is changing them.

Solar energy is the most accessible type of renewables for the general public!

Below, we will summarize solar energy advantages and disadvantages with comparisons to other types of renewables. After reading the content below, you will have a better understanding about solar energy pros and cons, and you will know more about why solar energy is the better choice to go green for the general consumer.

Before learning solar energy advantages and disadvantages—how do solar panels work?

Solar power panels can be seen just about anywhere throughout the United States and, increasingly, the rest of the world. Oddly, there are people who still aren’t really certain how it all works. Some even think the heat of the sun is used to make steam. Here’s a quick guide to how solar panels work and what happens inside our homes.

Generally, solar panels are made up of multiple modules of crystalline silicon cells. Silicon is a natural semiconductor. Each cell is made of two layers of cells—the negatively charged N layer and the positively charged P layer immediately below it. When light waves (photon particles) strike the layers, the bonds of the silicon atoms are disrupted and energy is generated.

To see how, we suggest to watch this short video named “How do solar panels work” developed by TED , which has gained more than 2 million views since it was published.

5 major advantages of solar energy

The principal advantage of solar energy: Nearly everyone can adopt directly!

[bctt tweet="The principal advantage of solar energy: Nearly everyone can adopt directly!" username="theSolarMag"]

Solar energy holds a number of significant advantages over other alternative energy sources in that individuals can invest in their own power generation. While there is an initial capital investment, those costs are dropping dramatically. And with major advances in home-based energy storage, the benefits of solar energy are increasing, and the advantages of solar energy are becoming more and more obvious year after year. All across the United States, the cost of solar power installation is dropping. The 2018 price has dropped 6% compared to the previous year.

There are many forms of alternative energy production: bioenergy and fuels, geothermal energy, hydroelectricity, and wind energy. All of them are “green,” and all of them are capital- and technology-intensive. In most cases, they are developed as large-scale utilities by governments or large corporations. Ranchers and farmers can invest in windmills for power (mostly to drive water pumps in wells), but none of these can serve the residential market (homeowners or apartment dwellers). Only solar power offers individuals affordable access through either the installation of home solar units or through a contract with a commercial solar power provider.

Actually, there are many uses of solar energy in our daily life, as there is also a huge variety of solar-powered consumer products available to easily adopt solar energy and a greener life. These include portable solar panels, solar-powered chargers, and solar lights . Plus, new ones are coming to the market every day. Therefore, among various solar energy advantages, the principal one is that nearly everyone can adopt directly.

Moreover, besides conventional solar cells, other technologies like perovskite solar cells and solar photovoltaic (PV) glass are offering brighter hopes. Though still in an early stage of ongoing research or with limited commercial availability, they are constantly improving and maturing.

With solar photovoltaic (PV) glass , your windows can help power your home and still offer that panoramic view! Those applications will continue to grow as builders incorporate PV glass into homes, office buildings, and high-rise towers. All a building has to do is present one face to the sun—and all of them do.

Advantage #2: Fulfill your social responsibility to reduce carbon emissions

Even though some people prefer not to see it, most people in the U.S. and around the world understand climate change and the need to cut our carbon emissions. People know the oceans are warming and rising. We see that the sea ice, north and south, is vanishing. So are the glaciers and the fresh water that feeds our rivers and streams. It’s not really about policies or regulations. People WANT to make a difference, and even the major power industries have begun to embrace greener living.

Every year, more people want to fulfill their responsibility and meet the challenges laid out in the United Nations’ Sustainable Development Goals 7 and 13. The goals aren’t so very complicated, and there is a lot that ordinary people can do.

Goal 7: Ensure access to affordable, reliable, sustainable, and modern energy for all.

It’s true that billions of people still need to burn wood, coal, or even animal dung for heat and cooking, but here in the developed world, we can choose to reduce our own carbon footprint. We can choose to invest in solar homes and, for some, solar-powered businesses. If we can’t install solar panels for the home, we can select regional solar power providers and use the wide variety of solar panel kits, solar-powered lights and electrical chargers that are available today.

Goal 13: Take urgent action to combat climate change and its impacts.

Climate change is impacting the whole world. The impact is global, and every nation and all people are affected. Climate change doesn’t recognize borders, and no country is immune. It is absolutely critical that the guidelines of the Paris Agreement be followed in every possible way. The agreement sets practical and attainable goals for the reduction of greenhouse gases.

Even when a national government refuses to honor the agreement, many states and cities do! In the U.S., 17 states including New York, California, most of New England, and the Mid-Atlantic States, among others, along with dozens of U.S. cities and corporations, will remain in compliance with the Paris Agreement and its goals. All of us can use our power to tell the governments of our cities and states to do that, too.

Advantage #3: Help cut your electricity bill and save money

The third advantage of solar energy is that installing solar power panels makes you a producer and reduces the electricity you get from your local utility. That, of course, reduces your electricity bill , but there’s a lot more than that. Solar panel installations are a two-way affair. When the owner generates more power than they use, in-home energy storage units get charged. And today, they come with programmable control units to hold their electricity and sell the excess back to your local utility during peak demand hours when the prices are highest.

For all the concern about high energy costs, few people actually take the time to understand their power bill. You don’t just get billed at one average rate. Power companies charge more for power during peak demand hours (generally during the day), and they charge less per kilowatt-hour at night when demand is lowest.

Modern control panels assure that homes and businesses rely on their self-generated solar power when demand is the highest to either reduce and sometimes eliminate the power drawn from your utility—and that’s when they sell the power, too. When demand is lower (after dark), homes depend on the utilities when it’s cheapest. If there is power remaining in storage, that gets used to reduce even those costs.

Few home-based solar power units generate enough power to entirely eliminate the power people buy from their utilities, but it does happen for those who invest in bigger arrays. The average solar unit in the U.S. is about 5–6 KWs. How much you will save depends on how big your array is, the capacity of your storage system, and the seasons—and, of course, where you live and the sunlight available to you.

Advantage #4: Enhance the resiliency and reliability of the electricity supply

[bctt tweet="Among the pros of solar energy, a significant point is that going solar brings a degree of independence from extreme weather events." username="theSolarMag"]

This solar energy advantage means that when heavy snows and winds bring down power lines or a lightning strike takes out power poles and transformers, solar owners will still be generating their own power. Those solar panels on your roof provide resiliency against the elements!

It doesn’t take a superstorm to knock out the electricity. We have an aging power grid, and many above-ground lines have been there for a quarter of a century, and in some places, those lines can be 40 years old or more. Increasing capacity is a big expense that many utilities don’t want to pay, while upgrades to support new development and power needs often get put on hold.

During the hot summer months (and those summers are getting hotter), “brownouts” occur with increasing frequency. One exciting point of solar energy advantages is that solar power owners can rely on their solar panels and storage systems to see them through when their neighbors have gone dark.

Advantage #5: Long-time warranty and low maintenance costs

Many people take a look at those “glass panels” on the roofs and envision shattered glass, hazards, and huge repair bills. These hardly happen. Solar cells may be relatively fragile, but they are protected under shatter-proof tempered glass with a flexible substrate protecting the cells. Even hail storms hardly cause anything more than minor damage.

Today, mounting systems are engineered to withstand major storms, and they’re customized by manufacturers to the climate conditions in different parts of the country. Manufacturers design, test, and certify their panels to withstand winds of 140 miles per hour. A category 5 hurricane has winds above 136 mph. It’s a good bet the solar panels for your home will survive all but the very worst storms. Most manufacturers provide a 25-year warranty for their panels, and installers carry insurance on their work.

There are maintenance costs, cleaning and such, and each manufacturer provides detailed instruction on the care of their particular units and wiring. You should look at all that, and often, the installation firms offer service agreements.

New technologies are entering the market, allowing people to monitor the performance of their solar technology along with their home appliances. Living on Internet of Things (IoT) monitoring services, 5G network, and new control systems offer the chance to fine-tune a home or business to gain the largest rate reductions and credits from their local utility. Efficiency is the name of the game, and soon, homeowners will do the tuning through a mobile app.

5 commonly recognized disadvantages of solar energy

Disadvantage #1: Some people may not have a suitable space

Solar panels aren’t the ultimate answer for everyone. For one thing, you need a place to put them. If you own your home and thus have your own roof or property to install an array in the yard, great! For people who live in apartment buildings, the prospects aren’t so bright, but there may be other solutions including choosing a regional solar power provider.

Every year, there are more industrial-scale solar firms supplying the energy market. There are also various solar-powered devices, chargers, and portable units to be explored. (We’ll talk about those later.)

Disadvantage #2: Relatively higher initial investment and longer ROI

There is indeed a higher start-up cost, and going solar does mean taking the longer view. But the costs are falling dramatically year after year, as panel production and installation increases all across the country. As mentioned above, the cost of purchase and installation dropped below the 2017 prices by 6%, and in 2018, solar costs will range from $11,380 to $14,990 (after tax credits) with an average cost ranging from $2.71 to $3.57/KWh. That changes the equation for many people, and the costs should continue to decline. According to recent stats, generally, the average payback time for a solar power system investment nowadays can be around 5-7 years.

There will always be an initial investment confronting homeowners who want to go solar, but an ever-creative industry is coming up with new marketing strategies to drive the business forward. One of them is a new lease-to-buy option  sponsored by manufacturers and supported by installers in their vast networks. Under these plans, professional installers will come to your home, design the proper solar panel system for your particular needs, install the system and accomplish your interface with your local power company, take care of all permits and licenses, and, in the overall, reduce the cost of getting solar power by about 50% of today’s cost.

Homeowners don’t get the tax rebate that installers and manufacturers do—but the homeowner gets the savings (between 10 and 30% of the present bill) with little and sometimes NO capital costs up front. Most leases run for 20-25 years, and at the end, the owner may renew the lease or purchase the solar unit outright.

Disadvantage #3: Power generation is weather-dependent

Solar energy isn’t the answer to every power problem everywhere in the world. Weather and location on the globe play roles in how efficient a solution can be provided by solar energy. Less sunlight will be available in places with more clouds and rain, and, of course, in northern latitudes, while the sun never sets in the summer, it also never rises in the winter.

Nevertheless, solar power is growing in the U.K. (lots of rain) and in Sweden, one of the lands of the midnight sun. Research from Sweden reveals an interesting fact: While there is less light during the spring and autumn, solar panels are more efficient in cold weather! Who knew? Solar power may never gain huge reductions in power bills in such places, but installations are growing all across the United States, even in the northern tier.

Disadvantage #4: Some potential pollution still exists

Among the cons of solar energy, pollution and environmental impacts are concerning many modern citizens who want to go solar. But all energy production creates some level of environmental impact. It’s unavoidable and nothing’s perfect.

Solar cell production uses a number of toxic metals such as lead, gallium arsenide, and cadmium. But these toxins are used inside production plants where strict environmental controls govern the operation, and none of it enters our environment. There are other impacts, too, like transportation and installation, but again, every power source has that.

The wind may be free energy with no pollution, but someone makes the windmills, and even geothermal power requires pipes, converters, and turbines. The key issue is that solar energy provides power with no direct impact on global warming. It’s a good choice for you to fulfill your social responsibility.

Disadvantage #5: Local customer services are not sufficient

There had been difficulties with sufficient customer service, and part of that came from the more mobile (some would say transient) nature of the solar installation business. All of that has changed over the last few years, along with the industry’s investment in training and what is becoming a nationwide standard of industry best practices with support from the U.S. Department of Energy.

As the solar industry has grown (nearly 300,000 Americans work in the industry, mostly as professional installers), those firms have become much more permanent. And with better-established warranties from manufacturers and service contracts being offered by the installation firms, the quality of the installations and customer services has improved greatly. However, buyers still need to get bids from multiple firms and check out their reputation (you wouldn’t get a new central air system from one unknown company, would you?).

Through an understanding of solar energy, the expansion of the solar industry has been enhanced and accelerated. Although plenty of solar manufacturers, suppliers, or consultancies have appeared in the market, local customer services are not sufficient enough to help professionally solve customers’ questions like personalized solar estimating, financing, installation, or daily maintenance.

But, with the help of constantly advancing modern information and communications technology (ICT) and innovative business models, solar customer services will definitely better satisfy every solar customer’s needs.

Actually, among the pros and cons of solar energy, we can see more pros than cons

After learning about solar energy advantages and disadvantages, even though there are still some cons of solar energy the industry keeps maturing. As we can see in lots of solar news , solar technology advancements like improved conversion efficiency and increased storage capacity continue year after year. The industry itself is investing heavily in excellence and cost-cutting as a result of the competition in the energy industry and for the consumer dollar. New marketing mechanisms are rolling out as fast as the technology, and solar installations are growing throughout the United States because of it.

Meanwhile, solar energy advantages will be with us forever . The sun is an inexhaustible resource, and for that day when our sun does finally give out (about 5 billion years in the future), we won’t have to worry about it. For now and into the future, solar energy will offer many more advantages than disadvantages .

Solar energy is the most accessible type of renewables for the general public

We now have a better understanding of the pros and cons of solar energy. After learning the advantages and disadvantages of solar energy, if we make comparisons between solar energy and other renewable energy resources, we find that:

• The wind is a wonderful source of power in certain locations but not others, and commercial wind turbines span 200 feet or more and can cost millions of dollars. Very few people have a backyard that can accommodate a wind turbine, and even then, wind is inconstant and is preferred to solar in only a few select locations.
• Bioenergy holds great potential if you have massive amounts of biodegradable material, a chemical plant, and no sense of smell. Chemical plants, conversion units, and generators really don’t work well in a home.
• Geothermal energy systems are very efficient and harvest the natural renewable energy of the earth—if you live next to a geyser. A few people in Colorado (and a few more in other places) could take advantage of this resource, but the heat still needs to be converted to energy we can use.
• Hydroelectric power stations require rivers moving down precipitous drops to gain enough momentum to power a dam’s turbines. While new low-dam power generators have been designed to generate power without fast-moving water, you still need to live next to a river to tap its power. Few of us can do this, and each of those generators cost about $1.5 million before the first watt is generated. They’re great for small towns and not so good for homeowners.

Solar energy is the most accessible type of renewable energy for the general public and for an individual to adopt a greener life directly. There are so many options, and more arrive every day. Each new technology is a call-to-action for those who care .

• The Advantages and Disadvantages of Solar Energy
• Energy 101: Resources to Help Understand Energy
• Energy Innovation

Solar energy pros and cons are a hot topic today. As the earth’s most plentiful source of energy, the sun holds enormous promise as a clean and dependable way to power our world.

When the radiant energy of the sun is converted to heat and electricity, it can provide energy to residences and businesses, and even power vehicles.

Now might be a good time to learn about solar energy advantages and explore adding a solar energy system to your home. Then you can decide: Is solar energy worth it?

When considering home energy options , it is important to understand how solar energy works . When sunlight hits a solar panel, a photovoltaic cell turns that light into direct current (DC) electricity. An inverter then converts it to alternating current (AC), which is what most devices in your home use.

Advantages of Solar Energy

The more we can capture the benefits of solar energy , the less we will rely on fossil fuels. Adding a solar energy system to your home allows you to tap into these solar energy advantages:

1. Solar energy is a renewable energy source and reduces carbon emissions

Solar energy is a renewable energy source, meaning you don’t ever use it up. Solar energy is clean. It creates no carbon emissions or other heat-trapping “greenhouse” gases. It avoids the environmental damage associated with mining or drilling for fossil fuels. Furthermore, solar energy also uses little to no water, unlike power plants that generate electricity using steam turbines.

2. ​​Solar energy can reduce your home’s electricity bill

A solar energy system for your home can reduce your reliance on the grid and help you save on your electricity bill . Some owners of residential solar energy systems may even have excess power that they can sell to the utility . Instead of paying a utility for electricity, homeowners get paid by the utility. You may not have to buy an entire solar energy system to cut your home’s electricity bill. Simply choose solar lights , lights that are powered by the sun instead of your home’s electrical system, to help save money.

3. Solar power can get you money back through Solar Renewable Energy Credits (SRECs)

Some states offer solar renewable energy certificates (SREC). Each one represents a megawatt-hour of electricity generated through solar energy. Electricity suppliers buy these certificates to satisfy their state’s Renewable Portfolio Standard, a requirement that a certain amount of their renewable energy come from solar. You can sell SRECs for your system's output, which is another way to earn money from your investment.

4. Homes with solar panels installed may improve home value

Home buyers will likely pay more for a house with solar panels installed. Considering solar energy pros and cons, the savings on electricity bills and the money earned selling power back to the utility, all count in the plus column. Residential solar energy systems are highly valued and can increase a home's resale value. The property value of a home with solar panels can be worth up to $15,000 more than its neighbors.

Solar systems are fairly easy to install and require very little maintenance. Both are handled by your solar provider, if you opt for a solar lease or power purchase agreement (PPA). Consider this as you ask yourself is solar energy worth it.

5. Solar panels have low maintenance costs

Solar panels are easy to maintain, as they have no moving parts that wear out over time. Just keep them clean and in good physical condition to keep them working properly. Between their low maintenance costs and average lifespan of 25 years , it can be easy to get your money’s worth when investing in solar panels.

6. Solar energy can generate electricity in any climate

Solar energy systems can generate electricity in any climate. One of the disadvantages of solar energy is that it’s subject to temporary weather disruption. Cloudy days reduce the amount of electricity you produce. Cold, however, doesn’t affect productivity. Snowfall can actually help your solar system, as the snow cleans the panels as it melts and sun reflected off the snow increases the amount of light hitting your panels. The result is more electricity production.

Disadvantages of Solar Energy

The disadvantages of solar energy are becoming fewer as the industry advances and grows, creating economies of scale. Technological advances are helping solar go mainstream. Here are how the disadvantages of solar energy and the pros and cons stack up.

1. The high initial costs of installing panels

The most commonly cited solar energy disadvantage, cost, is declining as the industry expands. The initial cost to buy and install the equipment is not cheap. Still, if cost is an issue, leasing options may reduce the amount of your initial outlay. If you do choose to buy, you will need to live in your home for a number of years before the system pays for itself. It’s a long-term investment better suited to property owners than renters.

2. Solar energy storage is expensive

Of the disadvantages of solar energy, the temporary decline in energy production during bad weather has been a major issue. Days with low solar energy, however, are having less of an effect due to advances in battery technology. Old technology for storing solar energy, like lead acid batteries are being replaced by alternatives. Lithium ion batteries offer greater power at a lower cost. Nickel-based batteries have an extremely long life. New technologies, like flow batteries, promise scale and durable power storage.

3. Solar doesn’t work for every roof type

Not every room will work well with solar panels. Orientation matters. If your roof doesn't face the sun, you won’t be able to capture enough solar energy. Roofs that angle into the sun tend to work better than flat roofs.

Roofing materials like asphalt shingles, metal and tiles make installing solar panels easier. If your room is made with other materials, installation may be more expensive. Part of what makes energy-efficient roofs is their ability to support solar panels.

4. Solar panels are dependent on sunlight

It’s obvious that solar panels need sunlight to generate electricity. They won’t produce electricity at night when you need it for light and they can be inefficient during storms and gloomy days. Your solar energy system needs batteries if you plan to fully depend on solar energy to power your home.

Batteries are one of the more expensive components of your system. Unlike solar panels, they do wear out and need careful maintenance to lengthen their lives. Comparing wind power vs. solar power , wind will keep generating electricity at night and during storms, as long as there is enough wind. Many people use both in residential systems.

Constellation Energy and Solar Energy

When weighing the pros and cons of solar energy for your home, there are additional options worth considering. Community solar projects are a great way to get the advantages of solar energy without buying and maintaining a system yourself.

If your home and roof won’t support solar panels or if you don’t have enough money to invest in one, community solar might be your answer. With this option, you agree to participating in a program that allows you receive credits for every kWh generated by the solar facility. You get a credit on your electricity bill proportional to your percentage of ownership in the project’s energy.
