DSP-Based Uniaxial Solar Tracking System

Solar tracking system is a device which can automatically locate and track the sun. It is mainly used to improve the power generation efficiency of solar array. At present, due to the development of the photovoltaic industry, more and more attention has been paid to solar tracking system. However, the previous solar tracking system can not meet the precision requirements, or the cost is too high to promote. Aiming at these two problems, this paper proposes a new solar tracking system, which uses DSP as microcontroller, collects illumination signals from the sensor to determine the position of solar illumination, and drives a motor to make the sensor rotate with the position of solar illumination, so that the sensor can always follow the sun illumination. It has the characteristics of high precision, simple structure and low cost.
