Research On Solar Energy Independent Photovoltaic Power System

As a new kind of renewable energy, the solar, with the advantage of inexhaustible and pollution-free and not be subjected to geographical limitations, etc., gets the rapid popularization and application.A major drawback in the photovoltaic systems is that the photoelectric conversion efficiency of photovoltaic cells is too low, so it can not turn power output at the most efficiency; and it also loses a large of energy in the course of its work because of the impact of the environment.Therefore, in order to get the maximum of the output of the power, we not only need to develop the photovoltaic materials with low-price and high energy conversion efficiency but also need to realize the high power output of the photovoltaic cells in the controls, which contains the photovoltaic automatic tracking control and maximum power tracking control.According to the work features of photovoltaic cells, we design photovoltaic automatic tracking control system and a maximum power tracking controller in this paper.
