Concentrating photovoltaic power generation light guide funnel module

Abstract

The invention relates to a concentrating photovoltaic light guide component, in particular to a concentrating photovoltaic power generation light guide funnel module, and belongs to the technical field of solar power generation. The concentrating photovoltaic power generation light guide funnel module comprises light guide funnels, connecting plates and fixed installation holes. Lower ports of the light guide funnels are directly welded to the connecting plates, the two opposite surfaces of each connecting plate are provided with the two fixed installation holes, and the light guide funnels are connected together through the connecting plates. The light guide funnels are simple in processing technology, simple in structure, few in consumable and low in weight; the light guide funnels cannot deform in the package and transportation processes and the subsequent installation process, and meanwhile it is guaranteed that converged sunlight is completely gathered onto an effective surface of a concentrating photovoltaic cell chip; a plurality of light guide funnels can be installed on the funnel module at a time, and therefore the processing efficiency is increased; the connecting plates of the funnel module can effectively protect internal circuits.

Description

technical field [0001] The invention relates to a concentrating photovoltaic light guiding component, in particular to a concentrating photovoltaic power generation light guiding funnel module, which belongs to the technical field of solar power generation. Background technique [0002] In the concentrated photovoltaic power generation system, the lens is mainly used to gather sunlight to the effective surface of the concentrated photovoltaic cell chip, so as to achieve the purpose of power generation. The current lens used generally has a convergence rate of about 80%. According to the current calculation, every 1% increase in conversion efficiency will reduce the electricity price by about 5%. Therefore, improving the lens convergence rate has become an important research topic for various companies. one. [0003] At present, some enterprises use the light guide funnel to improve the convergence rate of the lens. Although the light guide funnel has a good light guide func...

Problems solved by technology

[0003] At present, some enterprises use the light guide funnel to improve the convergence rate of the lens. Although the light guide funnel has a good light guide function, because its connecting plate (also called fixed mounting feet in some places) is "L" shaped or right angled " Z" shape, directly connected from the upper port of the light guide funnel, in the process of production, packaging and transportation, or later installation, the right angle is not easy to get 90° guarantee, so that the light guide to the effective surface of the concentrating photovoltaic cell chip appears. deviation, leading to a reduction in photovoltaic conversion efficiency; at the same time, because the "L" or "Z" shaped products use more materials than the "one" shaped products, and the number of light guide funnels used in each concentrated photovoltaic module is extremely large, so The overall weight of concentrating photovoltaic modules will increase, and the process of processing "L" or "Z" is also more complicated, and it also has the technical defect that only one light guide funnel can be installed at a time, resulting in very low processing efficiency
