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

We used data from the EnergySage Solar Marketplace to conduct an analysis of the range of prices that solar shoppers were quoted for 4.5 kW solar energy systems across the United States. On EnergySage, homeowners compare offers from solar installers to shop for the right home solar panel system at the right price.

The prices included in the table below are representative of what homeowners pay for a 4.5 kW solar energy system after the 30 percent federal tax credit for solar has been deducted. In some parts of the United States, there are additional solar rebates and incentives from the state government, local government, or utilities that can reduce your upfront costs even further. Some states also have a market for solar renewable energy certificates (SRECs), which means that you 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. 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.

It should come as no surprise that the amount of sunshine where you live is the most important factor determining how much electricity your solar panels actually produce.

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.
