I know the solar cell is not producing pollution but making the cell will. I am looking to compile a pollution cost per kilowatt.
the production of electricity from solar is almost zero. The production of the solar equipment is high, and the solar farm requires a very large area. Add that the solar panels need to be cooled with fresh water, so the water needs to be cleaned and
The following equation models the power produced by a solar panel over 1 day (x axis= time in minutes from 12am)(y axis= power in watts):
y= (4.7*10^-8)x^3 - (1.3*10^-4)x^2 + (0.12)x -32.15
