Solar power generation and heat collection system

Abstract

The invention relates to a light condenser which takes both power generation and heat supply demands into consideration and has high photoelectric and photo-thermal conversion efficiency. The solar power generation and heat collection system includes a light condenser for parallel superposition of light, and a parallel light receiver arranged adjacent to a condensing zone of the light condenser. The parallel light receiver includes a solar cell and a solar heat collection tube, which are back on to each other and integrally arranged. In need of solar power source, the solar cell of the parallel light receiver is opposed to the light reflection face of the light condenser; and in need of liquid heat source, the parallel light receiver is turned over so that the solar heat collection tube is opposed to the light reflection face of the light condenser. Since the light condenser is adopted, photoelectric conversion efficiency and photo-thermal conversion efficiency are high. Power supply or heat supply can be selected as required. As the light condenser is adopted, the photoelectric conversion efficiency or photo-thermal conversion efficiency is high.

Description

[0001] This application is a divisional application. The invention and creation name of the original application is "solar power generation and heat collection system", application number: 201110085377.8, and application date: April 6, 2011. technical field [0002] The invention relates to the technical field of solar energy concentration heat collection and power generation, in particular to a solar power generation heat collection system. Background technique [0003] Existing solar power generation or heating equipment often can only achieve a single function, that is, when using heat, there is no external power supplement; when generating power, the waste heat generated needs to be dissipated at a cost. Solar cells do not have constant temperature control. When there is sufficient sunlight and the ambient temperature is high, the solar cells’ power generation efficiency will decrease due to temperature rise, and some may even be damaged.

[0003] Existing solar power generation or heating equipment often can only achieve a single function, that is, when using heat, there is no external power supplement; when generating power, the waste heat generated needs to be dissipated at a cost

Solar cells do not have constant temperature control. When the sun is sufficient and the ambient temperature is high, the solar cells’ power generation efficiency will decrease due to temperature rise, and some may even be damaged.
