Abstract: (1765 Views)
In this paper, we have simulated the operation of fixed and tracking photovoltaic systems, considering the location of solar panel, local astronomical calendar and sun path. For this purpose, first, sun path and operation of the motor was simulated. Then, the dual axis sun tracker was modeled, and accordingly, generated power and the efficiency of both fixed and tracking photovoltaic systems were calculated. The calculation was made for Tehran for two summer and autumn days. The solar power, received power and generated power of solar panels were extracted. Our results proved that due to using tracking systems, solar panels receive almost all solar power. Therefore, the efficiency of tracking systems rises to 50.6% which is a considerable enhancement in comparison to the efficiency of fixed systems, which is 14.1%. The advantages of our dual tracking system over the other ones are the accuracy of sun path algorithm and no need for using sensors.
