Solar Photovoltaic Power Calculator

If you are considering installing solar photovoltaic panels, or are curious about the amount of energy solar panels could generate at your home or office this calculator will help.

The accuracy of this calculator's results is determined by:

  • The calculator's main input is real weather data, collected each and every hour of the year at a weather observation point in your locality. Most of the competitors use national/regional and monthly/annual averages.
  • The calculator takes account of the ability of your own property to harness the primary energy available, by evaluating the effects of the aspect of your property etc.
  • The calculator determines the energy output by the system based on the actual technical specification of solar panels and inverters, as tested by the manufacturers under STC (standard test conditions).
  • The calculator will provide answers to your solar energy queries in less than two minutes, from start to finish. We have adopted a 'need to know' basis for questions - you are not required to register or login, you are only asked to complete a very short form containing only questions that are important to the computations, submit your inputs and your report is ready in about 45 seconds.
