In a sunny location, sunlight has a power density of about 1 kW/m2. Photovoltaic solar cells can convert this power into electricity with 16% efficiency.
If a typical home uses 390 kW⋅h of electricity per month, how many square meters of solar cells would be required to meet its energy requirements? Assume that electricity can be generated from the sunlight for 8 h/day.
Express your answer using two significant figures.
