Fabrication of an energy dual-axis solar tracking system and performance analyses through optimal values of solar panel parameters

This work presents a hardware development of a solar tracking system using arduino pro mini and further analyzing the performance of dual axis solar tracking systems. The objective is to examine the performance of the parameters such as voltage, power, all day efficiency, cost; through different settings of solar tracker. The proposed work has been established on hardware and analyzed using software mode. The hardware has been set up using two servo motors, along with a light dependent resistor (LDRs), which senses the solar rays. Further the motions of the motors are performed by moving the solar panel towards point or location corresponding to the source of maximum light. The control portion was developed by using C programming as a software mode of operation. The control mechanism was targeted to the Arduino UNO for functioning of the hardware system. The result showed that the solar tracking system produces maximum all day power corresponding to dual axis tracker. It resulted in 25% more than that of a single axis tracker and 51% more than that of a fixed tilt angle. Moreover, a Therefore, a solar tracker can effectively capture the maximum sunlight source and can be used for any small applications in order to achieve more electrical power
