How much space does the system need to be installed?
Photovoltaic panels require approximately 100 sq ft for a 1 (kilowatt), Kwh system, 200 sq ft for a 2 Kwh system, 300 sq ft for a 3 Kwh system, and so on. So In terms of roof space, on average, for a 4kWh system you would need between 350 and 400 square feet of, preferably south facing, roof space. It is true that more efficient and often more expensive panels can generate more power per square foot than less efficient models. This is usually important to customers who have limited space but want to generate the maximum amount of power they can.
