Research on Photothermal Switching Technology of Tropical Photovoltaics

In the face of the current technology that the heat generated by the sun is still the main by-product of photovoltaic hydropower generation, and the technical problems of limited application range such as low temperature of hot water supply, the present invention proposes a system that combines photovoltaic hydropower generation with solar thermal power. Power generation can be converted in time to meet the needs of various energy forms in different seasons, different times. At the same time, the high-concentration function of the concentrator is used in both working states of photovoltaic power generation and photothermal power generation, which can carry out high-efficiency hydropower generation and high-efficiency heating, and provide heat and electricity with a wider range of uses.
