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.
Average solar energy system costs = $8.95 per watt. In order to compare the solar energy costs to conventional hydrocarbon fuels, we must covert the $8.95 per into KWH. Letâs make two calculations to measure the total electric energy output over the lifespan of the solar energy system.
