We analyzed solar quotes from the EnergySage Solar Marketplace to understand the range of prices that solar shoppers are paying for 12 kW solar energy systems across the United States. Homeowners who use EnergySage shop for the right home solar panel system at the right price by comparing multiple offers from solar installers in their area.

In the table below, you’ll find a range of prices that homeowners have paid for a 12 kW solar energy system in different states. These prices indicate gross cost before the federal tax credit for solar has been deducted. In some parts of the United States, you may also be able to access solar rebates and incentives from the state government, local government, or utilities that can cut 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 that does not offer additional solar incentives or rebates, reviewing offers from multiple solar companies will ensure that you get the best price for your solar panel system.

A reputable solar installer will be able to walk you through their proposal in detail.

How much electricity will a 12 kW solar system produce?

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. For example, if you install a 12 kW solar panel system on your roof in Phoenix, you’ll produce about 25 percent more electricity than if you installed the same system on a roof in Boston. However, that doesn’t mean you have to live in Arizona for solar to be a good option for your home – solar is a smart investment wherever electricity rates are high.

Below is a table with estimated average electricity production numbers for 12 kW solar energy systems in cities across the United States. As a comparison, the average U.S. household uses 877 kilowatt-hours (kWh) a month, a total of 10,649 kWh per year. We developed these estimates using PV Watts.

    I didn’t know that solar panels were different prices in different states. My husband and I have thought about getting solar panels, so that we could be more self-efficient. We will be sure to do some research, and we will be sure to see how expensive it is in my state.
