Problems solved by technology

[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.

Embodiment Construction

[0027] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

[0028] Such as figure 1 -10. The solar power generation and heat collection system of this embodiment includes: a concentrator a for parallel superimposition of light rays and a parallel light receiver 4 arranged adjacent to the concentrating belt of the concentrator a; the parallel light receiver 4 includes: The solar cell 4-1 and the solar heat collecting tube 4-2 that are set back to one body; when solar power is needed, the solar cell 4-1 of the parallel light receiver 4 is opposite to the reflective surface of the concentrator a; when a liquid heat source is needed , flip the parallel light receiver 4 so that the solar heat collecting tube 4-2 is opposite to the reflective surface of the concentrator a. In other implementation manners, the parallel light receiver 4 can adopt a single solar cell or a solar heat collecting tube.

[0029] The solar cell 4-1 ...

Abstract

The invention relates to a condenser which considers both requirements of power generation and heat supply and is high in photoelectric and photothermal conversion efficiency. A solar power generation and heat collection system comprises a condenser used for parallel overlapping of light and a parallel light receiver arranged close to a condenser strap of the condenser. The parallel light receiver comprises a solar battery and a solar heat collection tube which are oppositely and integrally arranged. When a solar power source is needed, the solar battery of the parallel light receiver is led to be opposite to the reflection surface of the condenser; and when a liquid heat source is needed, the parallel light receiver is overturned so as to lead the solar heat collection tube to be opposite to the reflection surface of the condenser. Due to the condenser, photoelectric or photothermal conversion efficiency is high, and further power supply or heat supply can be selected as required.

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.
