Comparison have been made for the two models.
How do you calculate the efficiency of a PV module?
The efficiency of a PV module is based on how well the incoming solar power is converted to usable electrical power. To find the percent efficiency of an electrical machine like a motor, divide the output power by the input power and then multiply by 100.
