3kW solar panel system cost: What are solar shoppers paying in your state?

To understand the range of prices that solar shoppers are paying for 3 kW solar energy systems across the United States, we analyzed solar quotes from the EnergySage Solar Marketplace. EnergySage makes it possible to shop for the right home solar panel system at the right price by comparing multiple offers from solar installers in your area.

The table below has a range of prices that homeowners have paid for a 3 kW solar energy system in different states. These prices indicate the net cost, which means that the 30 percent federal tax credit for solar has already been deducted. Depending on where you live, you may also be able to access solar rebates and incentives from the state government, local government, or utilities that can reduce your out-of-pocket solar costs even further. Some states also have a market for solar renewable energy certificates (SRECs), which means you can actually earn additional income by selling the SRECs your system generates.

Even if you live in an area without additional solar incentives or rebates, you can ensure that you get the best price for your solar panel system by reviewing offers from multiple solar companies.

It should come as no surprise to you that the amount of sunshine where you live is the most important factor that determines just how much electricity your solar panels will produce. For example, if you install a 3 kW solar panel system on your roof in Phoenix, you’ll generate about 25 percent more electricity over the course of a year than if you installed the same system on a roof in Boston. This isn’t to say that you have to live in Arizona for solar to be a good option for your home – if you have a high electricity bill, solar is a smart investment for you.
