| With conventional resources are exhausted constantly, the energy structure based on conventional energy would fail to catch up with the needs of the development gradually. So the renewable resources is developed and applied faster and faster. The solar energy is principle part of the renewable resources that has been our common ideas. In the field of solar energy utilization, the energy generation is one of important issues. It is important that the efficiency of the solar battery is raised and the cost of the photovoltaic generate electricity is reduced. So the popularization of solar energy utilization will be promoted.In this paper, a solar energy photovoltaic system in multi-mirror focusing solar radiation is designed. The main content is as follows:1,In order to exert bigger effect of photovoltaic battery, the photovoltaic battery output characteristic and influence reasons are analyzed. The solar collector with multi-mirror to strengthen solar radiation is designed. The efficiency of photovoltaic battery will be improved. The multi-mirror composing structure mode and designed method are given.2,The method combining the clock follows with optimum light density measurement is adopted, a automatic tracking control method of multi-mirror with two axis are used , It is more accurately to follow the sun position, and the best effect of optimum light density is attained.3,The relationship of generation power of photovoltaic cells with solar collector and the consume power of solar collector is analyzed, the control strategy to get optimum generate power is given.4,The emulational experiment system of photovoltaic generation with multi-mirrors is built, the function of automatic tracking and optimum generate power control is realized. |
