10kW solar systems are among the most popular solar energy system sizes in the country, producing enough electricity to power a home with slightly above-average electricity consumption. How much does a 10kW solar system cost? How much electricity will a 10kW solar system produce? How do you know you’re getting the best deal on a system? These are some of the key questions we will answer in this article.
How Much Does a 10kW Solar System Cost?
As of January 2017, the average cost of solar in the U.S. is $3.26 per watt ($32,600 for a 10 kilowatt system). That means that the total cost for a 10kW solar system would be $22,820 after the 30% Federal ITC discount (not factoring in any additional state rebates or incentives).

System price data from EnergySage’s Solar Marketplace
Through our network of pre-screened installation companies who participate in our Solar Marketplace, EnergySage has access to solar system pricing data from around the country. Using this data, we’ve compiled the table below to give you an idea of what a 10kW solar system might cost in your state, after the federal Investment Tax Credit (ITC) is taken into account.
Perhaps the most important thing to take away from the below table is that you should ask questions if you see prices higher than these. There may be a good reason to pay more, but if that’s the case, you should know why and understand how the system offers better value. Considering there are no assumed estimates for storage options like solar batteries, this table should be considered a 10kW grid tie solar system comparison.
How much does a 10 kW grid connected solar system cost in your state?
|State||10 kW solar system price range (2017)|
|Arizona||$18,179 – $23,780|
|California||$20,619 – $26,896|
|Colorado||$19,437 – $26,356|
|Florida||$18,509 – $24,406|
|Massachusetts||$21,398 – $27,582|
|Maryland||$19,500 – $24,719|
|New Jersey||$19,652 – $25,489|
|New York||$19,582 – $28,712|
|Texas||$17,991 – $23,954|
|Washington||$22,548 – $29,823|
Note: The prices listed above have already had the 30 percent federal tax credit for solar deducted.
How much electricity will a 10,000 watt solar system produce?
The amount of electricity that a solar energy system will produce will depend on a number of factors, including the quality of the parts used in the system and the angle and orientation of the solar panel array. If you are looking for a 10,000 kWh solar system, 10 kW of solar panels will produce more than enough electricity for your needs.
The most important factor determining exactly how much electricity your panels will produce is the amount of sunlight that shines in your area throughout the day. For example, all things being equal, a 10kW solar system in southern California would produce about 20% more electricity over the course of a year than a system in the Northeast.
Table 2 below shows average daily, monthly and annual solar energy production numbers for a 10kW solar system in various US cities. As you can see, systems located in sunnier cities produce more electricity than less sunny cities.
Solar electricity output of a 10kW solar energy system in various US cities
|City||Average daily kWh||Average monthly kWh||Average annual kWh|
|Las Vegas, NV||48.2||1,467||17,608|
|Los Angeles, CA||43.4||1,320||15,835|
|New York City||34.9||1,062||12,749|
Is solar worth it for you? Sunshine isn’t the only factor
The numbers in Table 2 will help you to calculate how much money you could potentially save on your power bill by going solar. But keep in mind that electricity production is only one determinant in how much you can save.

How do I know I’m being offered a good deal on a 10kW solar system?
The best way to know for sure whether an offer is a good deal is to educate yourself about what to look for. Our Solar Buyer’s Guide and Solar 101 page are good places to start. Here are some tips that will help you go solar with confidence:
Three Tips for Solar Shoppers
Homeowners who get multiple quotes save 10% or more
As with any big ticket purchase, shopping for a solar panel installation takes a lot of research and consideration, including a thorough review of the companies in your area. A recent report by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) recommended that consumers compare as many solar options as possible to avoid paying inflated prices offered by the large installers in the solar industry.
To find the smaller contractors that typically offer lower prices, you’ll need to use an installer network like EnergySage. You can receive free quotes from vetted installers local to you when you register your property on our Solar Marketplace – homeowners who get 3 or more quotes can expect to save $5,000 to $10,000 on their solar panel installation.
The biggest installers typically don’t offer the best price
The bigger isn’t always better mantra is one of the main reasons we strongly encourage homeowners to consider all of their solar options, not just the brands large enough to pay for the most advertising. A recent report by the U.S. government found that large installers are $2,000 to $5,000 more expensive than small solar companies. If you have offers from some of the big installers in solar, make sure you compare those bids with quotes from local installers to ensure you don’t overpay for solar.
Comparing all your equipment options is just as important
National-scale installers don’t just offer higher prices – they also tend to have fewer solar equipment options, which can have a significant impact on your system’s electricity production. By collecting a diverse array of solar bids, you can compare costs and savings based on the different equipment packages available to you.
There are multiple variables to consider when seeking out the best solar panels on the market. While certain panels will have higher efficiency ratings than others, investing in top-of-the-line solar equipment doesn’t always result in higher savings. The only way to find the “sweet spot” for your property is to evaluate quotes with varying equipment and financing offers.
For any homeowner in the early stage of shopping for solar that would just like a ballpark estimate for an installation, try our Solar Calculator that offers up front cost and long term savings estimates based on your location and roof type.
