At high magnification concentrator photovoltaic solar-thermal integrated system project for new progress

Therefore, effective heat dissipation, control of battery cell surface temperature is an important approach to optimize the system. Solar multiple controllers integrated photovoltaic solar-thermal systems, that is suitable for rural schools, hospitals, factories and other public buildings, remote villages and user villa, island, checkpoints and photovoltaic agriculture, has a broad market prospect. Taiwan pv news Polaris concentrator photovoltaic power generation technology is a concentrating device will be a large area of sunlight into a small area of photovoltaic battery power generation technology, sharply reduced the amount of photovoltaic cells, compared with the traditional photovoltaic cells, the dosage of the torch concentrator photovoltaic cells is reduced to 1/7000 ~ 1/10000, is an important innovation of photovoltaic industry. Concentrating photovoltaic power generation technology efficiency is high, cover an area of an area small, torch battery is the key of the photovoltaic industry innovation direction. The next two years in hengshui area medium-sized demonstration promotion, further push back what is the meaning and photovoltaic civilian fields such as agriculture, island border area. Engineering thermal physics, Chinese Academy of Sciences institute of heat and mass transfer research center based on high strength and heat transfer technology developed in recent years at high magnification concentrator photovoltaic battery temperature control method, in the high-power magnification concentrator photovoltaic solar-thermal industry made new progress. Light can also be combined with coal-fired power plants, the realization of complementary power generation, coal and waste heat refrigeration thermal power cross the summer issue of air cooling unit. Silicon wafer bellwether for high integration of concentrator photovoltaic solar-thermal systems, solar multiple controllers group completed the concentrator photovoltaic power generation and waste heat utilization system of thermodynamic modeling and optimization analysis, the optimum operation parameters and scheme is determined. Due to the concentrated photovoltaic cells under the environment of high temperature power generation efficiency is low, the group will, smartly combined cooling and heat utilization, has developed a unique high efficiency cooling and heat recovery system, the recovery of waste heat used for winter heating and summer cooling dehumidification, provide users with cold and hot wet electrical integration solution, can effectively reduce the unit cost of investment, but also meet the diverse needs of users. At present, the construction of the team has been in hebei hengshui power 15 kw high concentrated photovoltaic system support and tracking system, Taiwan pv news Polaris are in other parts of installation work, expected in July for demonstration operation. For temperature control problem of the photovoltaic cells, the research design developed with heat pipe technology as the core of passive heat transfer temperature control devices, realize the control of concentrator photovoltaic battery hot surface temperature and heat transfer and conversion. However, photovoltaic power generation investment concentrated photovoltaic cells will produce a larger quantity of heat, so as to reduce the efficiency of photovoltaic cells, even burned down the battery. The project won the national key research and development plan of international science and technology cooperation project ( 2016 yfe0118100) Support, has three SCI papers published articles, authorized 2 3 invention patents and utility model patents, and participated in one industry standards. In experiments, research on the r&d and design of system module box outdoor test, results show that the module efficiency reached 26% on average, the back what is meant by the solar energy comprehensive utilization rate of more than 75%, silicon wafer bellwether achieves the international advanced level.
