How many square meters of photovoltaic cells would be required to light a 60-W computer monitor? The efficiency of photovoltaic cells is 15% for converting 1000 W/m ² of solar energy to electricity.

Question

Quizplus · Accepted Answer

The efficiency of photovoltaic cells is 15%, which means that only 15% of the solar energy is converted to electricity. Therefore, the area of photovoltaic cells required to light a 60-W computer monitor is:Area = (Power of computer monitor) / (Efficiency of photovoltaic cells * Solar energy per unit area)= 60 W / (0.15 * 1000 W/m^2)= 0.40 m^2
