This document discusses mechanical solar trackers and sensors that are attached to photovoltaic solar panels to increase their energy generation efficiency. It mentions solar trackers that can follow the sun's position throughout the day by adjusting the angle of the solar panels. The document provides two references on the topics of solar tracking and the design of solar tracker systems for photovoltaic power plants.
