A solar panel is a device that helps convert sunlight into electricity. The pros of using solar panels include a lower carbon footprint, lower electric bills, potentially higher home value and tax credits. The cons include high initial costs, specific roof requirements, possible higher property taxes and storage costs.
According to the U.S. Energy Information Administration’s 2020 Residential Energy Consumption Survey, the majority of energy use in American homes goes toward seasonal heating and cooling. However, only about 5% of residential sector energy end use in 2020 came from renewable sources like solar.
Solar power has become more affordable over time, and it offers communities and homeowners the opportunity to switch to a more sustainable, renewable and abundant energy source. Every home and every community is different, however. There are plenty of pros and cons to consider.

Save on your electric bill. | Not every roof will work. |
Increase your home value. | Potential property tax increase. |

Advantages of solar panels
Nearly 4 million American households have switched to solar power. Here are a few of the benefits of residential solar panels.
Lower your carbon footprint
According to the Environmental Protection Agency, electric power generation was the second-largest emitter of CO2 in 2022. Solar energy systems do not contribute to air pollution or emit CO2.
The environmental impact of creating and installing solar panels is typically offset in one to four years, depending on the system. With a 30-year lifespan for most residential systems, this long-term environmental benefit could outweigh the short-term environmental cost.

Save on your electric bill
Switching to solar can reduce your monthly electric bill. How much you might save depends on how much power you use, the size of your system, if you buy or rent the solar panels, how much sun your roof gets and your local electricity rates.
With net metering, for example, the extra electricity your solar panels generate goes back to the power grid. The utility company then credits your account for that extra power, which is another way to help lower your electricity bill.
Increase your home value
Just like that nice chef’s kitchen with stainless steel appliances, solar panels can be a desirable upgrade for a lot of buyers. According to a 2019 survey by Zillow, homes with solar-energy systems sold for 4.1% more than homes without solar-energy systems. For median-value homes, that meant an extra $9,274.
Federal tax credits
The federal government offers a 30% tax credit on the total cost of installing solar panels on your home between 2022 and 2032.
Check for state tax credits and rebates from your utility provider or solar installer for additional savings.
Drawbacks of solar panels
It’s not always sunny switching to solar energy. Here are a few of the limitations of solar panels.
Upfront costs
The panels, inverter (which converts the sun's power into usable electricity), batteries for storing power, wiring and labor for a five-kilowatt (kW) residential system may cost anywhere from $10,000 to $25,000 or more.
Not every roof will work
The best roofs for solar panels face south, slope between 15 to 40 degrees and get direct sunlight for most of the day.
That doesn't mean you're out of luck if yours faces east or west; your solar panels might just generate less energy.
Certain roofing materials, such as cedar shakes or slate tiles, may be more difficult for installers to work with.

Potential property tax increase
Because property taxes are based on property value, an increase in your property’s value could raise in your property taxes.
Whether this will happen and how much the tax will increase depends on your state and local tax code.
Some state governments want to incentivize the solar switch by offering property tax exemptions for solar installations.
Solar storage expense
To power your home at night or on a cloudy day, when solar panels don’t generate much energy, you’ll need a solar storage battery. This comes with an extra cost. A solar-plus-storage system typically ranges from $25,000 to $35,000, depending on the size of the battery.
A separate solar battery system — if you already have the panels, but no storage — could cost anywhere from $12,000 to $22,000.
Who solar panels are best for
Solar isn’t the best option for everyone. A switch to solar energy might be a good fit for you if:
You own your home.
Your energy usage and monthly electric bill is high.
Your roof is unobstructed by trees or other structures and south-facing with a slope between 15 to 40 degrees.
You live in a state with net metering.
You qualify for state and federal tax incentives or rebates.
If you’re a renter or your roof isn’t suitable for a solar panel setup, you can still benefit from solar energy with community solar programs.
