Sunlight has a power density of 2.0 kW/m2 in a sunny location. This can be converted by photovoltaic solar cells into electricity with 23% efficiency. Calculate the square meter of solar cells needed to meet the energy requirement of a typical home that uses 467 kWh of electricity per month. (Assume that electricity can be generated from the sunlight for 7.5 hours per day)
