How Much Energy Does A Solar Panel Produce? | EnergySage
About 97% of home solar panels quoted in the second half of 2025 produce between 400 and 460 watts, based on thousands of quotes from the EnergySage Marketplace. But wattage alone
A solar panel produces between 1.1 and 2.5 kilowatt-hours of power in one day, which amounts to 33 to 75 kWh per month. As an average home in the US uses about 900 kWh, you will need between 27 and 12 solar panels to cover that usage, depending on the panel efficiency and how many watts each solar panel produce.
And to build a 6.7 kW solar system, you need 14 500-watt solar panels. If you have a smaller household, you could cover your energy use with a less expensive 4 kW solar system that produces 18 kWh of electrical energy per day, and you can build it with just 8 500W solar panels. Again, this applies in the ideal, testing conditions.
According to the National Renewable Energy Laboratory (NREL), the output of solar panels degrades at a rate of 0.5% per year. This means a 20-year-old solar panel will produce approximately 90% of the electricity it produced when out of the box. This means you don't have to dispose of your solar panels right after the official end-of-life.
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:
