Solar Panel Output

Annual Solar Panel Energy Output (in kWh) = kK x system kWp. A rough kK value you can use for most of the UK is: 950 kWh/kWp per year. So say we have a 4 kWp solar panel system we estimate that the annual output will be: Energy Output = kK x kWp = 950 x 4 = 3,800 kWh. A couple of rough rules of thumb: If facing SE or SW you can apply a 95% factor
