Question 4 An energy efficient house in Barcelona is to be fitted with a rooftop PV array that will annually displace all the 3600 kWh/yr of electricity that the home uses. How many kW (DC, STC) of panels will be required and what area will be needed (assuming crystalline silicon modules with a nominal efficiency of 12.5%)? Assume that the roof is south-facing with moderate title angle. The panels will be mounted at the same angle as the roof, which means a shallow pitch. The year average roof insolation is 4.60 kWh/m2/day and assume an DC-AC conversion efficiency of 75%.
