Software Control Method for a Solar Tracking System

Solar collector technologies operate with better performance when the Sun beam direction is normal to the capturing surface, and for that to happen despite the relative movement of the Sun, solar tracking systems are used. Therefore, there are rules and standards that need minimum accuracy for these tracking systems to be used in solar collectors' evaluation. Obtaining accuracy is one of the key tasks in such a system. This paper presents the software method of a solar tracker system that uses a webcam as the sensing device combined with image processing technique that is developed in the computer to locate the location of the Sun's position.
