Monocrystalline vs Polycrystalline Solar Panels
To work out how much electricity a solar panel will generate for your home we need to multiply the number of sunshine hours by the power output of the solar panel. For example, in the case of a 300 W solar panel, we would calculate 4.5 x 300 (sunlight hours x power output) which equals 1,350 watt-hours (Wh) or 1.35 kWh.
