Calculating the Kilowatt Hours Your Solar Panels Produce

Number of panels = DC rating / Panel Rating (e.g. 25o W) *note this is important b/c panels are rated in watts, and the systems are rated in kilowatts (1000 watts). So a 7.53 kW system = 7530 Watts and a 250 watt panel = .250 kW. example: 7.53 kW x 1000 / 250 watt = 30.12 panels, so roughly 30 250 panels (30 x 250W = 7500 Watts = 7.5 kW)
