How many kW should my solar system be?
Based on our experience, our rule of thumb is that 1 kilowatt (kW) of solar installed in NC will produce 1,300 kilowatt hours (kWh) per year. So if your home uses 12,000 kWh per year, we’d estimate you need around a 9.2 kW solar system to meet 100% of your energy needs (12,000/1,300 = 9.2).
