exposed to an average solar insol? A silicon solar cell array works at an efficiency of 8.1% in sunlight and is exposed to an average solar insolation of 230 Wm-2. If the array recoups the energy cost in 8 years, calculate the energy required to fabricate the solar cells (answer in MJ/m2).
if you can show me the calculations that'll be great!~
