New Mechanism for Solar Trackers

The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575–49,837 exajoules (EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012. [15] Solar panel tracking solutions are a more advanced technology for mounting photovoltaic panels. Solar trackers like sun flowers follow the sun path in the sky to achieve more radiations. This helps to increase output energy. This paper presents determination of optimal angle of photovoltaic panels using intelligence algorithms. The proposed approach has been tested on two-axis sun tracker with discrete motion and the results are compared. The results show that the proposed method has a high speed and accuracy to track the sun s path and the output energy of the PV system is high. Obviously this method helps to protect our environment because its clean energy and the loss of the system is minimum.
