摘要：The amount of solar energy captured by a sun collector determines the output power generated for thermal or photovoltaic applications. Hence, accurate solar tracking systems have an important role in the performance of solar collecting technologies. Although, more than 20 years of research in this filed, low cost and simple tracking systems that precisely keep the angle of view through the sun trajectory, is still a challenge that must be met by designer to incorporate it in a practical system without compromising accuracy. In this article the design, implementation and evaluation of a compact two-axes solar tracking system is presented. The system consists of a video processing based sensor connected to a microcontroller that computes a sun-positioning algorithm. The developed structure, by eliminating expensive computing systems, allows closed loop solar tracking as simple, low cost with minimal configuration. The evaluation results show solar tracking average accuracy of 0.0135 degrees for the azimuth angle and 0.0196 degrees for the zenith angle
