Essay

A house at 40ºN latitude has a roof of dimensions 8 m by 15 m. This area is covered with photovoltaic panels at the optimal fixed angle with an efficiency of $17 \%$ . Assuming average sky conditions, what is the annual energy production from this installation? If this electricity were generated by a coal-fired thermal plant operating at $38 \%$ efficiency, how much coal would be needed? On the basis of this comparison, what is the annual reduction (in kilograms) of $\mathrm { CO } _ { 2 }$ that results from this use of photovoltaics?
