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.

Abstract

The invention relates to a condenser which gives consideration to power generation and heat supply needs and is high in photoelectric and solar thermal conversion efficiency. A solar power generation and heat collection system comprises a condensator and a parallel light receiver, wherein the condensator is used for parallel superposition of light, and the parallel light receiver is arranged at a condensation band adjacent to the condensator and comprises a solar cell and a solar heat collection tube which are integrally arranged oppositely. When a solar power source is needed, a reflective surface of the solar cell of the parallel light receiver is opposite to that of the condensator; and when a liquid heat source is needed, the parallel light receiver is overturned to enable the solar heat collection tube to be opposite to the reflecting surface of the condensator. By the aid of the condensator, photoelectric or solar thermal conversion efficiency is high, so that power supply or heat supply can be selected as required.
