We looked at data from the EnergySage Solar Marketplace, the leading comparison-shopping platform for homeowners who are 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.

How much electricity will a 25 kW solar system produce?

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.
