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).
Solar energy systems are becoming increasingly popular and affordable across the United States. If you’re shopping around for solar energy, you may be wondering what size of solar energy system is most appropriate for you. System size considerations are especially important if you are thinking about purchasing a system as opposed to going solar with a lease or power purchase agreement

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.
How much does a 10 kW solar system cost in your state?

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.

|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.

Three Tips for Solar Shoppers
When it comes to solar quotes, the more the merrier
As with any big ticket purchase, shopping for a solar panel installation is a long process that will include a lot of research. Amidst that decision process should be a thorough review of every option available to you and every company that serves your area. Of course, in order to find the smaller contractors that cannot afford to put up billboard ads or run TV commercials across your state, you’ll need to use an installer network like EnergySage. If you’d like to get some free quotes from pre-screened solar companies in your state or even town, 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 10 kW solar panel installation.
The biggest installer will not always 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 big enough to buy the most advertising. In residential solar, a few major companies control more than half of the overall market share, and their business model is built on the assumption that homeowners won’t bother getting multiple quotes. On the contrary, small installers on EnergySage are aware that they are competing for your business and thus offer lower quotes on average. If you have offers from some of the big companies in solar, make sure you compare those bids with quotes from local installers in your area to guarantee you don’t overpay for solar.
Comparing all your equipment options is just as important
Just as large installers will not need to offer lower prices because of the nature of reduced competition, they are also unlikely to offer a variety of solar equipment options – they may just offer one brand of solar panel and inverter. For this reason, it is equally as important to get a diverse array of solar bids so you can compare costs and savings based on the different equipment packages available to you.
Certain panels will have much higher efficiency ratings than others. Depending on where you live and the roof you have, you may or may not need to pay more for top-notch solar equipment. There are multiple variables to consider when looking for the best solar panels on the market. Your roof may best suit an economy solar panel – the only way to find out is to look at quotes that have varying equipment and financing offers.
