Advantages of solar energy
We’ve decided to give you the good news first – the advantages of solar energy are listed below.
Solar saves money on your electricity bills for 25 years or more
The biggest benefit of solar energy is that it can reduce your electricity bills.
As of 2024, the average household can save about $1,500 per year on electric bills when they install solar panels! With these levels of savings, most homeowners can break even on their solar investment in 12 years or less.
Solar power systems save money by reducing how much energy you need to buy from the grid. In areas with net metering policies, you can even sell excess energy your solar panels generate to your utility, saving you even more money!
Insurance against rising power prices
Electricity prices are high and only keep getting more expensive. According to the U.S. Energy Information Administration, the average cost of electricity is about $0.16 per kilowatt-hour (kWh) - a 4.1% increase from last year.
Solar panels protect you from these rising electricity costs by generating electricity for your home to use. Instead of buying power from your utility that raises rates every year, you can use the solar energy generated right on your roof.
As electric rates get higher, you’ll still be using that solar power, saving you even more money each time your utility raises its rates.
Solar is cheaper than ever
While electricity prices have continued to climb, solar panel installation costs have steadily fallen.
In 2010, the average-sized solar system cost over $50,000. Today, it costs less than half that!
According to our 2024 Solar Industry Survey, 54% of solar installers reported the price they paid for solar panels decreased in 2023.
Solar energy is environmentally friendly
No carbon emissions are released into the atmosphere when solar panels generate electricity, making solar energy a clean power source. Most utility companies source their energy from fossil fuels like natural gas and coal, which have widespread negative health and environmental impacts when burned.
Solar is also a renewable source of energy, meaning that the sun’s power won’t deplete as we use it to make solar electricity. The sun’s energy will never “run out” – so you can always take advantage of it without hurting the earth!
Homeowners who install solar panels have a lower carbon footprint and help in the fight against climate change.
Solar panels can increase home value
The experts at SolarReviews analyzed over 400 homes on Zillow and found that, on average, homes with solar panels sold for 6.8% more than homes without solar panels.
Installing solar panels improves your home’s value and can make it attractive to future home buyers!
Solar energy is a renewable energy source
Solar is also a renewable source of energy, meaning that the sun’s power won’t deplete as we use it to make solar electricity. The sun’s energy will never “run out” – so you can always take advantage of it without hurting the earth!
Fossil fuels, on the other hand, are a finite resource. There is a limited supply on earth, and when we run out, it’s gone.
Solar energy benefits your community
Solar is a clean energy source, so no carbon dioxide or other harmful pollutants are released when it’s generated, increasing overall air quality and human health. The more solar we use, the less air pollution there will be!
Home solar can also reduce stress on the electricity grid, especially when paired with battery storage. With fewer people using the grid, the chance of a power outage decreases. When you go solar — you’re the nicest neighbor on the block!
Solar power has diverse uses
Photovoltaic energy can be used in many small and large-scale projects. From powering a home to running space satellites, solar panels are a great way to access energy in even the most remote places.
Solar panels are most commonly used on residential rooftops and large solar farms. However, some smaller-scale uses include solar phone chargers, solar-powered outdoor lights, and portable solar panels for camping and RVs.
Solar technology keeps improving
Thanks to various technological advances in solar, solar panels today are nearly 40% more efficient than they were in 2010.
The solar industry is key to a clean energy future, so a lot of work is being put into researching and developing the best technologies possible. New types of solar cells are being fine-tuned every year to create the best solar panels possible!
Solar incentive programs can keep costs low
There are a variety of solar panel incentives and rebate programs to help make solar more affordable.
The largest incentive is the federal solar tax credit, which provides homeowners who install solar panels or batteries with a tax credit equal to 30% of their system installation costs.
Performance-based incentives like Solar Renewable Energy Credits, or SRECs, can put even more money in your pocket when you install solar panels!
Solar works in different climates and environments
Many people think solar panels will only work in extremely sunny places like Arizona. Believe it or not, some of the best states for home solar aren’t the ones that get the most sunshine!
Solar panels can work in cold climates and, in fact, can operate better in them! Even cloudy weather can’t stop solar energy. Solar panels will still work in cloudy weather, but not as efficiently as they can in full sun.
Solar increases energy independence
Solar panels allow homeowners to create their own energy instead of relying on the electrical grid, helping them achieve energy independence and take control of where their home gets energy.
On a larger scale, solar energy systems in the United States would help the entire country achieve energy independence, reducing our reliance on other countries to get energy resources like foreign oil.
Low maintenance costs
Solar panel maintenance is generally minimal and usually consists of solar panel cleanings once or twice a year to avoid dirt and buildup if you don’t get regular rainfall.
Solar system equipment generally has very low failure rates because they don’t have moving parts, especially when you choose reliable brands and a trusted installer. Any issues or repairs that do arise are likely covered by a solar warranty.
Solar is a great financial investment
Solar panels can pay for themselves in just a few years with the savings accumulated on your electricity bill. In some cases, solar panels can provide a better return on investment than something like an index fund.
Disadvantages of solar energy
Despite all the benefits solar has to offer, there are also some downsides. After all, nothing’s perfect! Check out the disadvantages of solar power below:
High upfront cost
Even though solar panel system costs have dropped over the past decade, it’s still an expensive initial investment.
In 2024, the average solar installation will cost between $18,000 and $20,000 before any incentives are applied. That’s a lot of money for many homeowners, but there are financing options to help with the high initial cost of solar panels.
Solar panel manufacturing has some environmental impact
While generating solar power is emission-free, manufacturing solar panels does have an environmental impact, though it’s generally less severe than that of mining and burning fossil fuels.
Manufacturing plants release greenhouse gas emissions into the atmosphere, and mining for materials used in solar panels can damage the surrounding area.
Solar panel recycling programs are limited
Solar panels can be recycled at the end of their 25-year lifespan. However, because most installed solar panels in the U.S. are still in use, there aren’t many solar panel recycling programs available.
Limited recycling options mean that some panels that are decommissioned end up in landfills, which is less than ideal.
Installing solar panels can impact the surrounding area
Large solar farms can negatively impact the ecosystems they are installed in. For example, a large ground-mounted solar system may impact the migration route of some animals. It can also amplify the effects of erosion in an area by disturbing the soil.
Roof characteristics and size constraints
Not all roofs are suitable for solar. Solar panels work best on south-facing roofs with plenty of unshaded space.
Some homeowners might not have enough room for all of the solar panels needed to cover their electricity bills. This could be because their roof is small or complex or has many obstructions, such as skylights and vents.
Solar is an intermittent energy source
Solar energy is considered an intermittent energy source because how much energy solar panels produce is generally weather dependent. Also, the sun's intensity varies with location, the time of year, and the time of day, so solar energy production is different all over. However, solar battery storage makes solar energy available anytime, even at night!
Solar panels could increase your property taxes and homeowners insurance
Solar panels add value to your home, which is great! But it also means that solar panels will increase how much you have to pay in property taxes. However, many states and municipalities offer property tax exemptions for solar installations, so you won’t have to worry about increased tax payments.
Homeowner’s insurance is also based on the value of your home. If solar increases your home’s value, your insurance will likely increase, too. Speak to your insurance broker to find out specifics about your policy.
Value depends on local policy
The initial cost of solar is the biggest reason customers turn away from it, which is why some states have created solar-friendly policies to make installing solar panels more accessible.
Unfortunately, the policies and incentives you get can depend on where you live, who your utility provider is, and your eligibility. If you live in a state that doesn’t prioritize expanding solar, you might pay more for solar and earn lower savings.
Finding the right installer can be difficult
Solar is a 25-year investment, so you must find a reliable installer. A few bad apples in the solar industry have made it hard for homeowners to figure out who to trust, and deceptive, spammy sales tactics leave a bad impression.
Luckily for you, SolarReviews makes it easy for homeowners to connect with trustworthy local solar companies, taking the stress out of going solar.

Solar panels frequently asked questions (FAQ)
Still unsure about solar? Here are some frequently asked questions pertaining to the pros and cons of solar panels.
How do solar panels work?
Solar panels produce electricity through a process called the photovoltaic effect. In this process, sunlight hits the silicon in solar panels, causing their electrons to produce a reaction. This reaction generates an electric current that can power appliances and devices.

How do solar panels save money?
Solar panels save you money by generating electricity you home can use, which reduces how much power you buy from your utility.
Some utilities also offer net metering programs that allow you to earn credits for any excess solar energy produced that can cover the cost of any electricity you do take from the grid, bringing in additional savings.
Just be aware, net metering won’t be around forever. Some states, like California, have been changing their net metering policies and homeowner’s are saving as much money as they used to.
Can I run my whole house on solar panels?
Technically, yes – but not 24/7.
For most home installations, solar panels can run your house during the day, when the panels are producing the most energy.
Solar panels don't generate energy at night, so after the sun goes down you will rely on your utility or a solar battery to run your home. However, your solar panel system can be sized to generate enough energy during the day to cover costs later in the day.
Do I need to add battery storage with my solar panels?
It’s not mandatory to install a solar battery unless you plan to use solar to power an off-grid home. Installing a solar battery does come with other benefits though, such as providing backup power during a grid outage and saving extra money if you don’t have access to net metering. Energy storage installations are expensive and don’t always pan out financially.

How long do solar panels last?
Most solar panels are built to have a lifespan of 25 years, so consider this a long-term investment. Some panels are even warrantied to last 30 years! After you reach the 25-year mark, your panels will still work, but they won’t operate as efficiently as they once did.
Do solar panels work in bad weather?
Yes – solar panels still work during cloudy days or rainy weather. However, solar panels will generate less electricity in overcast conditions than in full sun.
Can I install solar panels myself?
Yes – it is possible to install solar panels yourself by purchasing a DIY solar panel kit. Taking the DIY route can help cut down on installation costs, but we don’t recommend it. Installing solar panels is a dangerous job, and you run the risk of injury by doing it yourself.
DIY installations may also void certain warranties and could even be illegal to connect to the grid. Take our advice and contact a local professional installer if you want the safest and best results.
