Description

technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a foldable solar photovoltaic power generation system based on optical fiber conduction. 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 sy...

AI Technical Summary

Problems solved by technology

[0003] However, the concentrating power generation system has the following problems: (1) The structure of the concentrator is sophisticated and complex, and the overall design and manufacture are difficult; (2) The concentrating problem of single crystal silicon cannot be effective at 3 to 5 times the concentrating intensity To reduce the cost of photovoltaic power generation, in order to greatly reduce the cost of photovoltaic power generation, it must reach about 10; (3) heat dissipation, ordinary silicon panels will cause blistering and oxidation problems under 2 to 5 times the intensity of sunlight, thereby greatly reducing light energy Conversion efficiency and affect the service life of the equipment; (4) Reflector problems, since the working environment of the equipment is usually set in deserts, Gobi deserts and other sunny high-temperature zones, the anti-aging and anti-wear process manufacturing technical requirements for reflectors Higher, thus increasing the manufacturing cost of the entire system; (5) The solar positioning and tracking system is a key component to ensure that the solar cell is always at the focal point of the concentrator and effectively concentrates light. Its structure is sophisticated and complex, and the use and maintenance costs higher

[0011] This technical solution adopts a single parabolic concentrator, which is still a traditional concentrator structure. There are problems that the concentrator structure is precise and complex, and the overall design and manufacture are difficult.
