How Much Energy Does A Solar Panel Produce?
If you''re thinking about going solar, one of your biggest questions is likely: how much electricity can a solar panel actually produce? This in-depth guide breaks down the
In the United States, the average daily solar insolation (sunlight exposure) ranges from 3 to 5 hours. Using this range and the panel's efficiency, we can estimate daily energy production: At 3 hours of sunlight: 400 watts x 3 hours = 1,200 watt-hours (or 1.2 kilowatt-hours, kWh)
The most frequently quoted panels are around 400 watts, so we'll use this as an example. If you live in a sunny state like California, your panel's production ratio is probably around 1.5, meaning a 10 kW system produces 15,000 kWh of electricity in a year.
The electrical output power is about 150 kWh. The annual electrical output in a sunny climate can be up to 300,000 kWh/year. (Photo: uni-solar.com)
