As of January 2017, the average cost of solar in the U.S. is $3.26 per watt ($11,410 for a 3.5 kilowatt system). That means that the total cost for a 3.5kW solar system would be $7,987 after the 30% Federal ITC discount (not factoring in any additional state rebates or incentives).

3.5 kW solar panel system cost: What are average prices in your state?

Using data from the EnergySage Solar Marketplace, the largest comparison-shopping platform for homeowners looking to install a solar panel system, we analyzed the range of prices that solar shoppers were quoted for 3.5kW solar energy systems across the United States.

The prices that you see in the table below represent what you can expect to pay after the 30 percent federal tax credit for solar has been deducted. Depending on where you live, there might be other solar rebates and incentives from the state government, local government, or your utility that can reduce your upfront costs even further. If there’s a market for solar renewable energy certificates (SRECs) in your state, you may also be able to sell the SRECs your system generates for extra income.

Even if you live in an area that doesn’t offer any additional solar incentives or rebates, reviewing offers from multiple solar companies guarantee you get the best price for your solar panel system. Homeowners who compare solar offers on the EnergySage Solar Marketplace generally save 20 percent simply by shopping around for the best solar option for their home.

How much electricity will a smaller solar system produce?

Sunshine is the most important factor determining how much electricity your solar panels will produce. For example, if you install a 3.5kW solar panel system on your roof in Las Vegas, you’ll produce about 30 percent more electricity than if you installed the same system on a roof in Philadelphia. However, that doesn’t mean you have to live in Nevada for solar to be a good option for your home – solar is a smart investment wherever electricity rates are high.

In the table below, you’ll find estimated average electricity production numbers for 3kW solar energy systems in cities across the United States. As a comparison, the average U.S. household uses 911 kilowatt-hours (kWh) a month, a total of 10,932 kWh per year. We used PV Watts, a tool from the National Renewable Energy Laboratory, to develop these estimates.
