PV module efficiency is the ratio of the electrical power output Pout, compared to the solar power input Pin, hitting the module. Pout can be taken to be PMAX, since the solar cell can be operated up to its maximum power output to get the maximum efficiency. The efficiency of a typical solar array is normally low at around 10-12%.
