Control of photovoltaic power generation capacity by solar tracking system based on photoelectric sensor

Recently, solar energy has become the major element in photovoltaic power generation as a pollution-free and renewable clean energy source. However, the development of solar photovoltaic power generation face several drawbacks which include low efficiency of photovoltaic conversion. Theoretically, the application of solar tracking technology can improve the solar absorption efficiency of ∼35%. Thus, this study analyzed the solar energy utilization for maximizing power generation efficiency and improving photovoltaic power generation capacity. Based on the understanding of the operation principles and the composition of solar tracking system, this study designed a set of photoelectric sensor based solar tracking system. Solar energy acquired by the solar tracking system cannot be fully utilized as photovoltaic system and thus to solve such problem, this study carried out tracking control at the maximum power point of the photovoltaic system with designing a circuit controlling system.
