The effectiveness of solar energy absorption has become an issue in photovoltaic (PV) performance. In addition to environmental considerations such as cloud shadows, the ever-changing position of the sun is a determining factor in maximizing the output of electrical energy from PV systems. This research proposes a design of a dual axis solar tracker to increase energy production and discusses its function to track the sun's location in the effective way. To verify the effectiveness of the proposed system, a test is conducted by comparing the system's performance with a system that does not employ a solar position tracking system know as a fixed system.The test is carried out under several conditions, including on a sunny day, a cloudy day, and a cloudy day with intermittent rain. According to the test results, the solar position tracking system with dual axes is more efficient at generating electrical energy in PV systems. The electrical energy generated is 18.56% higher than that of a fixed system. © 2022 Little Lion Scientific
