Solar thermal wind power generation system combing light voltage technology

Abstract

The invention relates to a solar chimney power generation system combining the photovoltaic technology, comprising a solar chimney and a solar thermal collector, wherein, the ceiling of the solar thermal collector is stuck with a thin film solar PV panel; or the bottom surface of the solar thermal collector is paved with the solar panel. The thin film solar PV panel stuck on the ceiling of the solar thermal collector is non-light tight. The solar panel paved on the bottom surface of the solar thermal collector is an ordinary monocrystalline silicon solar PV panel. The system can take full advantage of the light energy and the heat energy of the solar energy, after the solar panel converts the light energy of the solar energy into the electrical energy, the remaining solar energy is used for heating the air entering the solar thermal collector in the form of heat energy; the PV panel can be cooled perfectly to guarantee the efficiency and the generated output of the PV power generation system; the system raises the rate of utilization of the solar chimney power generation system on the solar energy and raises the generating efficiency of the solar chimney power generation system by about 30 percents.

Problems solved by technology

However, a difficult problem that plagues photovoltaic power generation technology at present is the cooling problem of photovoltaic panels (Huang Hulin, Han Dong, Kong Lingbin. Research on natural ventilation and cooling of photovoltaic building materials solar panels [J]. Solar Energy Sinica, 2006, 27 (3) : 309~313)

Usually without cooling, the temperature of photovoltaic panels under direct sunlight will reach above 70°C, which seriously affects the performance of semiconductor materials
