...produce 1.5 kW of power to run? A silicon solar cell array, with a collection efficiency of 13%, is required to produce 1.5 kW of power to run a small pump. If the array is positioned to collect 340 Wm-2 of energy from the sun, how large an area (in m2) does the array need to be to achieve...

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...
