Problems solved by technology
[0003] However, the concentrating power generation system has the following problems: (1) The structure of the concentrator is precise and complex, and the overall design and manufacture are difficult; (2) The solar positioning and tracking system has high requirements for the long-term reliability of the system operation, so further Increased overall construction cost and operation and maintenance costs
[0009] This technical solution is firstly used for indoor lighting. Although optical fiber is used for optical fiber transmission, the lighting unit still has the problem of precise and complex structure, and the positioning unit is required to cooperate with tracking the sun, and the operating cost is relatively high.

Embodiment Construction
[0035] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0036] Such as Figure 1 to Figure 5 As shown, an optical fiber conduction solar photovoltaic power generation system of the present invention includes a light collection unit, a conduction unit and a power generation unit. The light-collecting unit is an optical fiber light-collecting layer structure 1, which includes a reflective layer 11 and an optical fiber braiding layer 12 arranged in sequence from bottom to top, and the optical fiber braiding layer 12 is woven into a surface from unclad optical fiber bundles according to the weft method. The fiber optic braid 12 has two fiber bundle ends.
[0037] Such as Figure 4As shown, when sunlight irradiates the entire section of optical fiber of the optical fiber braid 12, part of the light refracts and enters the optical fiber, and under the action of the reflective layer, part...

Description
technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to an optical fiber conduction solar photovoltaic power generation system. Background technique [0002] The solar photovoltaic power generation system converts the sun's light energy directly into electrical energy through solar cells for external output. It is mainly divided into two categories: concentrating power generation systems and non-concentrating power generation systems. The concentrating power generation system is mainly composed of solar cells, concentrators, and sunlight positioning and tracking systems. The application of concentrators can focus sunlight to a receiving surface (solar cells) that is 1 / 10 to 1 / 1000 or even smaller than the incident surface In general, compared with non-concentrating power generation systems, concentrating power generation systems can greatly reduce the use area of solar cells and improve system conversion e...
