Under STC (Standard Test Conditions), a 1 kW solar panel produces 1 kWh of electricity in one hour. The total solar energy produced from a solar panel depends on the sunlight hours & its intensity. The electricity produced from a solar panel is often calculated on a daily, monthly, and yearly basis.
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:
Here, your 200-watt solar panel could theoretically produce an average of 1,000 watt-hours (1 kilowatt-hour) of usable electricity daily. In this same location, though, a larger-wattage solar panel would be able to produce more electricity each day with the same amount of sunlight.
A 300-watt solar panel will produce anywhere from 0.90 to 1.35 kWh per day (at 4-6 peak sun hours locations). 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).
