Abstract

The invention discloses a solar power generation heat collecting method and a special device thereof. The method comprises a condensing method, a receiving method and an automatic tracing method, wherein the receiving method is: sunlight which is condensed by a condensing system is focused to a focus point III-V compound photovoltaic cell, the generated electric power is synchronized through an inverter or is collected by a storage battery, and the produced heat is collected by a circular water circuit. The special device comprises a condensing system, a receiving system and an automatic tracing system. A small condensing lens is used for reflecting the light, so the light reflection efficiency can reach 95 percent; a big lens is used for condensing and focusing, so the optical energy density of the sunlight can be greatly improved to more than 1000 times; a gallium arsenide solar module is selected, so the conversion efficiency is improved, and the electric power which is two to three times of that of an ordinary photovoltaic cell can be generated; and the automatic tracing system is used, so the generated power of the entire system is improved by more than 30 percent compared with the traditional fixed-type system. In addition, a movable installation way and a fixed installation way can be adopted, so the device has wide application range.

Description

technical field [0001] The invention relates to a solar power generation heat collection system, in particular to a solar power generation heat collection method and a special device thereof. Background technique [0002] At present, with the increasing shortage of traditional energy and the deterioration of the global environment, countries are paying more and more attention to renewable energy. Among many renewable energy sources, only solar energy is inexhaustible, inexhaustible and non-polluting, which is the renewable energy source with the most development potential. The utilization of solar energy includes photovoltaic, photothermal and so on. [0003] In recent years, with the continuous improvement of conversion efficiency and the decreasing thickness of cells, crystalline silicon solar cells have gradually occupied the mainstream of the market. However, the rapid development of crystalline silicon cells has led to a shortage of silicon raw materials and a large a...
