How Much Power Does A 10kW Solar System Produce? (Not 10 kWh)

A 10kW solar system does not produce 10 kWh per day. That’s a bit of a misconception. We are going to look at exactly how many kWh does a 10kW solar system produce per day, per month, and per year.

On top of that, you will get these two very useful resources:

  1. 10kW Solar System kWh Calculator. Just input peak sun hours at your location, and the calculator will determine how much power 10kW solar system produces there per day, per month, and per year.
  2. 10kW Solar Panels Power Output Per Day, Per Month, And Per Year Chart. We have calculated 10kWh daily, monthly, and yearly kWh output for areas with 3.0 peak sun hours all the way to places with 8.0 peak sun hours, and summarized the result in a neat chart.

Here are a quick ranges from the chart:

  • 10kW solar system will produce anywhere from 30 kWh to 80 kWh per day (for Alaska and Arizona, respectively). If we presume US national residential electricity price to be about $0.15/kWh, that’s $4.50 to $12.00 worth of electricity per day.
  • 10kW solar system will produce anywhere from 900 kWh to 2,400 kWh per month. That’s $135 to $360 worth of electricity per month.
  • 10kW solar system will produce anywhere from 10,950 kWh to 29,200 kWh per year. That’s $1,642.50 to a whopping $4,380 worth of electricity per year.

To calculate the 10kW solar system output, we need to have a good grasp of peak sun hours. If you check this average peak sun hours chart by state (for all 50 US states), you can see that we get anywhere between 3 and 7 peak sun hours per day.

Peak sun hours are basically a measure of how sunny your location is. Here is how you can think about how many kWh will a 10kW system produce per day, depending on the number of peak sun hours:

  • 10kW solar system at a location with 1 peak sun hour will produce 10 kWh of electricity per day.
  • 10kW solar system at a location with 2 peak sun hour will produce 20 kWh of electricity per day.
  • 10kW solar system at a location with 3 peak sun hour will produce 30 kWh of electricity per day.
  • 10kW solar system at a location with 4 peak sun hour will produce 40 kWh of electricity per day.
  • 10kW solar system at a location with 5 peak sun hour will produce 50 kWh of electricity per day.
  • 10kW solar system at a location with 6 peak sun hour will produce 60 kWh of electricity per day.
  • 10kW solar system at a location with 7 peak sun hour will produce 70 kWh of electricity per day.
  • 10kW solar system at a location with 8 peak sun hour will produce 80 kWh of electricity per day.

Get a sense of it? We can write the 10kW solar panels’ electricity production per day, per month, and per year, in equations like this:

10kW Power Production Per Day = 10kW × Peak Sun Hours

10kW Power Production Per Month = 10kW × Peak Sun Hours × 30 Days

10kW Power Production Per Year = 10kW × Peak Sun Hours × 365 Days

Quick Example: Let’s say you want to install a 10kW solar system in Texas. According to the peak sun hours by state data, Texas received 4.92 peak sun hours (yearly average). How much power will this 10kW solar system generate in Texas? Let’s use the 3 equations from above:

10kW Power Production Per Day (Texas) = 10kW × 4.92h = 49.2 kWh/Day

10kW Power Production Per Month (Texas) = 10kW × 4.92h × 30 Days = 1,476 kWh/Month

10kW Power Production Per Year (Texas) = 10kW × 4.92h × 365 Days = 17,958 kWh/Year

If we take into account Texas residential electricity price ($0.1482/kWh as of November 2022, according to EIA), an average 10kW solar system will generate $7.29 per day, $218.74 per month, and $2661.38 per year in electricity.

This was just one example. You can check the peak sun hours for you state/location, and use the 10kW Solar System kWh Calculator. It will tell you everything – kWh/Day, kWh/Month, and kWh/Year. Below the calculator, you also get the complete chart with summarized 10kW power production rates for locations with different sun exposure:

Here is how this 10kW solar output calculator works:

Let’s say you live in sunny California. You consult this state-by-state chart, and see that California has a yearly average of 5.38 peak sun hours per day. Slide that slider to ‘5.38’ and you get the results:

An average 10kW solar system in California will generate 53.80 kWh per day, 1,614 kWh per month, and 19,637 kWh per year.

Here is the full 10kW system output per day, month, and year for very cold climates (3.0 peak sun hours) to incredibly sunny climates (8.0 peak sun hours):
