Solar Tracking System

A solar tracking system is a device that orients a roof-mounted array of photovoltaic (PV) panels, or a similar device such as solar thermal collectors or a tropical heliostat, towards the sun in order to maximize the amount of energy produced. The most common type of tracking system uses a variety of sensors to detect the sun's position, and then adjusts the panel's angle to maintain optimal alignment with incoming radiation. Such systems typically increase the energy production of the modules by 30–50%, while also reducing the land area required to meet a given power generation threshold.
