Comparison of Dual-Axis Solar Tracker with Static Solar Plate

Solar power is an important component of renewable energy for a long time. Solar power provides various benefits to residential consumers. This paper presents an automatic solar tracking system which aligns solar panels in the direction of solar rays in order to obtain maximum solar power. The tracking system automatically changes the direction depending on the light intensity. A comparison of the automatic solar tracking system has been made with the static solar plate and it is found that dual-axis solar tracker is more efficient as compared to the static solar plate system. The automatic solar tracking system reduces the number of solar panel arrays in comparison with the conventional system. The automatic solar tracking system is tested in a simulation environment and electrical parameters like voltage, current and power have been observed at different times during the day. An IoT monitoring system is also used to monitor the parameters from the static solar plate and dual-axis solar tracker systems. With the help of an automatic tracking system, the annual output has increased approximately by 38%.
