As of January 2022, the average cost of solar in the U.S. is $2.77 per watt - that comes out to $69,250 for a 25-kilowatt system. That means the total 25 kW solar system cost would be $51,245 after the federal solar tax credit discount (not factoring in any additional state rebates or incentives).

We looked at data from the EnergySage Solar Marketplace, the leading comparison-shopping platform for homeowners considering home solar panel systems, to find out just how much solar shoppers are paying for 25 kW solar energy systems in different states across the U.S.

The prices listed below have not had the federal tax credit for solar deducted. Depending on where you live, you might have additional state or local solar incentives and rebates that reduce the price even more. You may even earn extra income by selling your system's solar renewable energy certificates (SRECs).

Even if there are no other incentives where you live, comparing multiple offers from solar companies is essential to ensure you find the best deal. Homeowners who register their property on EnergySage can save 10 percent or more just by shopping around for the right option for their home – the equivalent of thousands in savings on a 25 kW system.

Remember, the cost of solar depends on a lot of factors, so these numbers are just meant to be a starting point. In most cases, you should be able to find a 25 kW solar system in this price range – if you receive offers from solar companies that are much higher or lower, be sure to ask follow-up questions.

The amount of electricity your solar panels produce depends on many factors, including the direction and angle of your roof. The most important one is how sunny it is where you live – for example, a 25 kW system in Las Vegas makes about 30 percent more electricity in a year than one in Philadelphia. That being said, you don't have to live in the Southwest for solar to make sense for you. The cost of electricity where you live is the biggest determinant of your solar savings.

The table below shows the average estimated electricity production numbers for 25 kW solar energy systems in cities across the U.S. By comparison, the average household in the U.S. uses 893 kilowatt-hours (kWh) a month, which equals 10,715 kWh per year. We estimated these numbers using PV Watts, a tool developed by the National Renewable Energy Laboratory.
