To figure out how many kilowatt-hours (kWh) your solar panel system puts out per year, you need to multiply the size of your system in kW DC times the .8 derate factor times the number of hours of sun. So if you have a 7.5 kW DC system working an average of 5 hours per day, 365 days a year, itâll result in 10,950 kWh in a year.

The average number of homes powered per megawatt of PV for a given state is simply the quotient of the average PV system performance estimate and the average annual household consumption.
