Question

Quizplus · Accepted Answer

Solar energy is most concentrated at places where the angle of incidence is 90°, which means that the sunlight is falling perpendicular to the surface. This is because when sunlight enters at an angle, it is spread out over a larger area and therefore less concentrated. So, the more perpendicular the angle, the more concentrated the solar energy.
