Solar power: in this problem you will provide back-of-the envelop calculations for a small solar generator. the problem relies on your ability to calculate things like p iv, area, etc. 4. estimate how much power could be generated by the solar panel if it worked with maximum efficiency. (this is a general physics style calculation). estimate how much power is actually used in the rotation of the propeller blades photo-cells are often based on the cds semi-conductor device. explain how a cds solar cell works. how might the cds solar cell be responsible for the entire loss of energy in this system?
