One such device is a solar concentrator. A solar concentrator (Fig. 1) at its core consists of a system of mirrors and an energy receiver. The mirrors are all oriented to reflect incoming sunlight toward the receiver. In doing so, the mirrors increase the amount of light, and thus the amount of energy, being sent to the receiver.
