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.

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

  1. 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.

  2. 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.

  3.  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.

For any homeowner in the early stage of solar shopping that would just like to get 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. For those looking to get quotes from local installers today, check out our quote comparison platform.
