Top plate of concentrating solar module

Abstract

The invention relates to a top plate of a concentrating solar module, and belongs to the technical field of solar power generation. The top plate comprises a top plate body and a lens fixing groove formed in the top plate body. The top plate is directly fixed to a top support of the concentrating solar module, can effectively and accurately position a lens and also can guarantee that the focal lengths of all small lens bodies are completely uniform.

Description

technical field [0001] The invention relates to a top plate of a concentrating solar module, which belongs to the technical field of concentrating photovoltaic power generation. Background technique [0002] The concentrating photovoltaic power generation system mainly uses lenses to gather sunlight to the concentrating photovoltaic cell chip, so as to achieve the purpose of power generation. The lens on the concentrating solar module is composed of toughened glass and many small lenses, so when designing and installing the lens, it is necessary to consider how to fix the lens to ensure that the focal length of each small lens is consistent. The existing design and installation use 4 pieces of metal strips fix the 4 end faces of the lens on the frame of the concentrating solar module respectively. This fixing method cannot guarantee the fixed position of the lens. At the same time, because the 4 end faces are respectively fixed, the force of the 4 end faces of the lens canno...

The lens on the concentrating solar module is composed of toughened glass and many small lenses, so when designing and installing the lens, it is necessary to consider how to fix the lens to ensure that the focal length of each small lens is consistent. The existing design and installation use 4 pieces of metal strips fix the 4 end faces of the lens on the frame of the concentrating solar module respectively. This fixing method cannot guarantee the fixed position of the lens. At the same time, because the 4 end faces are respectively fixed, the force of the 4 end faces of the lens cannot be guaranteed to be consistent. As a result, the lens is not installed horizontally, which will cause the focal length of each small lens to be inconsistent, that is, the focal spot where the sun's rays are converged to the concentrating solar cell chip through the lens is different, which will seriously affect the concentration of solar energy.
