Before you calculate your energy output you must know your solar radiation level aka solar insolation.
The National Renewable Energy Laboratory found in a 2012 study that solar panel output falls by an average of about 08 percent annually. Solar power as a function of time in kWh or Wh that your solar panel can produce taking into account its rated power and solar energy available at your place. The panels are in the UK. Take note of the annual average value which can be used below to estimate energy output.
