The basic formula for determining solar panel power output is: Power (W) = Area (m²) x Efficiency (%) x Solar Irradiance (W/m²) For a practical daily calculation that's easier to use, you can multiply your panel's wattage by the peak sun hours in your location:. The basic formula for determining solar panel power output is: Power (W) = Area (m²) x Efficiency (%) x Solar Irradiance (W/m²) For a practical daily calculation that's easier to use, you can multiply your panel's wattage by the peak sun hours in your location:. Now, the amount of electricity in terms of kWh any solar panel will produce depends on only these two factors: Solar Panel Size (Wattage). Most common solar panel sizes include 100-watt, 300-watt, and 400-watt solar panels, for example. The biggest the rated wattage of a solar panel, the more kWh. . Solar panels generate electricity through the photovoltaic (PV) effect, a process that converts sunlight into usable power. When sunlight strikes the solar cells within a panel, it excites electrons in the semiconductor material, typically silicon, creating an electric current.
