Solar Cell Efficiency

Joel Said:

A silicon solar cell array works at an efficiency of 17% in sunlight. If the solar array is exposed to an aver?

We Answered:

The solar array produces 600 watts. Since it is 17% efficient, this means it must be receiving 600/.17 watts of insolation, or 3529 watts. If the insolation is 196 watts per square meter, to get 3529 watts, you'd need 3529/196 or 18 square meters. So that's your answer.
