A New Adaptive Algorithm for Two-Axis Sun Tracker without Sensor
In recent years, sun tracking systems are being increasingly developed to improve the efficiency of PV panels. Due to problems of tracking methods which uses optical sensors, new methods with less practical problems are developing day by day. In this article, we suggest a new method to reduce the problems which exist with sun tracking. In this method, instead of using optical sensor, an adaptive algorithm is used, where recursive equations are employed to calculate Azimuth and Elevation angles of sun. We applied this method on a two-axis sun tracker system with fixed panel on 45° system. Then calculate the efficiency of PV panels. Finally, by comparing the Results of this method with respect to method of optical sensors, it has been shown that the efficiency of this method is higher than methods which used optical sensors.
