Another "Easy" Question
The household experiences an average sunlight intensity of 700 W/m2 for 6 hours each day. If the efficiency of converting solar energy to electricity is 12%, what area of photovoltaic panels would be necessary to supply the household’s electricity? A typical household uses 5000 kWh/year of electricity.
P = ηIA
P = power
η= efficiency
I = intensity of sunlight (in W/m2)
A = area of solar collector
How do you account for the fact that there's only light intensity 6 hours each day?
