A young solar energy enthusiast is planning to install a photo-voltaic system in a location where the average solar irradiance is 5 kw-hr/m?. He considers using 5 monocrystalline solar panels each with an area of 2 m² and a cell efficiency of 18%. The system efficiency is 75%. A. Estimate the monthly electrical energy output B. Calculate the monthly capacity factor if each panel has a rated power of 400 W. C. If his actual electrical energy requirement per month is 400 kw-hr, how many more PV panels does he need to add?
