PV arrays work best when the sun's rays shine ___________ to the cells because of the effect of tilt angle.
A) parallel
B) perpendicular
C) level
D) plumb

Question

Quizplus · Accepted Answer

PV arrays work best when the sun's rays shine perpendicular to the cells because this maximizes the amount of sunlight that can be absorbed by the cells. The tilt angle of the cells can also affect their efficiency, with the optimal angle depending on the latitude of the location and the season. However, in general, having the cells perpendicular to the sun's rays provides the most efficient energy output.
