Average Solar Panel Output Per Day On average, a typical solar panel produces about 2 kilowatt-hours (kWh) of energy daily. Understanding how many kWh a solar panel can generate is crucial as this amount varies depending on the total system size, panel efficiency, and peak sunlight hours, which differ by geographic location.
A 100-watt solar panel installed in a sunny location (5.79 peak sun hours per day) will produce 0.43 kWh per day. That's not all that much, right? However, if you have a 5kW solar system (comprised of 50 100-watt solar panels), the whole system will produce 21.71 kWh/day at this location.
A 400-watt solar panel will produce anywhere from 1.20 to 1.80 kWh per day (at 4-6 peak sun hours locations). The biggest 700-watt solar panel will produce anywhere from 2.10 to 3.15 kWh per day (at 4-6 peak sun hours locations). Let's have a look at solar systems as well:
As a general rule, with an average irradiance of 4 peak-sun-hours/day, 1 watt of solar panel rated power will produce on average 4 watt-hours (Wh) of energy. This amount equates to 0.004kWh, so a 300 watt solar panel will generate 1.22kWh/day. The precise amount depends on the location irradiance. How much kWh does a solar panel produce?
In California and Texas, where we have the most solar panels installed, we get 5.38 and 4.92 peak sun hours per day, respectively. Quick outtake from the calculator and chart: For 1 kWh per day, you would need about a 300-watt solar panel. For 10kW per day, you would need about a 3kW solar system.
The biggest 700-watt solar panel will produce anywhere from 2.10 to 3.15 kWh per day (at 4-6 peak sun hours locations). Let's have a look at solar systems as well: A 6kW solar system will produce anywhere from 18 to 27 kWh per day (at 4-6 peak sun hours locations).
