“Virtual” make Virtual Solar Tracker designed for Solar Energy Sensor’s installations to track the sun’s position. The sun’s position is calculated using the GPS data provided by inbuilt GPS module. From this data the Virtual Solar Tracker calculates the ‘zenith angle’ and the ‘azimuth angle’, which together exactly specify the position of the sun in the sky to within 0.1° by activating the internal actuators until the correct position is reached.
