If you’re looking to install solar panels on your roof, a 7-kilowatt (kW) solar energy system can be the right size to significantly reduce your electricity costs. Want to know the best way to ensure you’re getting the right price for your solar panel installation and maximizing your long-term savings? Compare offers for 7 kW solar systems with the prices that have been quoted to other solar shoppers in your area.
How much does a 7kW solar system cost?
As of July 2021, the average cost of solar in the U.S. is $2.76 per watt ($19,320 for a 7-kilowatt system). That means that the total cost for a 7kW solar system would be $14,297 after the federal solar tax credit discount (not factoring in any additional state rebates or incentives).
7 kW solar panel system cost: what are solar shoppers paying in your state?
To understand the range of prices that solar shoppers are paying for 7 kW solar energy systems across the United States, we analyzed solar quotes from the EnergySage Solar Marketplace. 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 represent the price that homeowners pay for a 7 kW solar energy system 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). If that’s the case, 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. Homeowners who compare solar offers on the EnergySage Solar Marketplace generally save 20 percent simply by reviewing multiple solar options from different companies.
How much does a 7,000 watt solar system cost in my state?

|Arizona||$14,700 – $17,920|
|California||$16,730 – $20,510|
|Colorado||$20,230 – $23,450|

These numbers offer a good point of reference for homeowners beginning the solar shopping process. However, there are many factors that determine the cost of a solar energy system – high-efficiency equipment and special accommodations for complicated roofs are just two of the factors that can impact system price. Reputable solar installers will be able to walk you through their proposal in detail, so if you receive a quote from a solar company that is significantly higher or lower than the range for a 7 kW solar system in your state, simply ask them for an explanation.
How much electricity will a 7 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 7 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.
In the table below are estimated average electricity production numbers for 7 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 used PV Watts, a tool from the National Renewable Energy Laboratory, to develop these estimates.
