Research On Photovoltaic System With Multi-mirror Focusing Solar Radiation

Energy is an important material foundation for social and economicdevelopment, accompanied by continuous consumption of conventional energy, thecommunity is soaring and calls for energy shortages, accelerate the developmentand utilization of solar energy as the main renewable energy has been a widespreadconcern. In the field of solar energy utilization, solar power is an importantresearch direction in energy use, How to improve the power generation efficiencyof the solar panels is one of the important topic of PV systems research. In thispaper, a solar energy photovoltaic system with multi-mirror focusing solar radiationis designed, the purpose is to improve the efficiency of photovoltaic powergeneration and solar energy utilization, reduce the cost of PV systems.The main content of this paper is as follows:1. On the basis of analysis of the output characteristics of the photovoltaic cell,the influence of the two important parameters of the light intensity and temperature,the design of the parabolic concentrator, a composition by the multi-plane mirror isdesigned to enhance the degree of solar radiation, and to improve the powergeneration efficiency of the photovoltaic cell.2. Concentrating photovoltaic system, and ideas to improve the efficiency ofsolar receivers, this paper designs a multi-plane mirror reflector type condenser,given the layout of the plane mirror plane mirror reflective condenser mode,tracking the position of the sun moving equations of motion and coordination ofmulti-plane mirror control algorithm.3. To achieve the desired converging effect, the use of a clock tracking methodto accurately locate the position of the sun, by using the azimuth and elevationangle of the two-axis tracking control, so that the condenser to accurately track theposition of the sun, to achieve optimal condensing effect.4. A multi-mirror concentration photovoltaic system is designed. The systemcomposition structure and hardware schematics and design diagram is presented.The result of the experimentation shows that this method is useful and valuable.
