Alignment packaging method for high-power concentrating photovoltaic modules

Abstract

The invention discloses an alignment packaging method for a high-power concentrating photovoltaic module. The high-power concentrating photovoltaic module includes a concentrator upper bottom plate, an electrical lower bottom plate and a frame, and a plurality of Concentrating lens, a plurality of solar cells corresponding to the concentrating lens one by one are arranged on the electrical lower base plate. The present invention analyzes and compares the central positions of the condenser lens on the upper base plate of the concentrator and the solar battery sheet on the lower electrical base plate through an alignment platform, and aligns the corresponding positions on the basis of the coincidence of the centers of the upper base plate of the concentrator and the lower electrical base plate. The deviation between the condenser lens and the center position of the solar cell is compared with the preset center deviation to judge, and the rapid alignment packaging is realized under the condition of ensuring the alignment accuracy.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to an alignment packaging method of a high-power concentrating photovoltaic module. Background technique [0002] At present, the concentrating module is generally packaged by three parts: the upper base plate of the concentrator, the lower electrical base plate, and the frame. Since the concentrator is generally a lens array, and the electrical bottom plate is correspondingly arranged with solar cells, and the general high-power concentrator assembly has a concentrating factor of about 500 times, that is, the concentrator area / solar cell area ≈ 500, so in When packaging, it is necessary to align the units in the upper base plate of the concentrator and the electrical lower base plate, such as figure 2 As shown, the so-called alignment requires that the central axis 5 of each condenser lens 6 is collinear with the central axis 5 of the corresponding sol...

Since the concentrator is generally a lens array, and the electrical bottom plate is correspondingly arranged with solar cells, and the general high-power concentrator assembly has a concentrating factor of about 500 times, that is, the concentrator area / solar cell area ≈ 500, so in When packaging, it is necessary to align the units in the upper base plate of the concentrator and the electrical lower base plate, such as figure 2 As shown, the so-called alignment requires that the central axis 5 of each condenser lens 6 is in line with the central axis 5 of the corresponding solar cell 7 and is perpendicular to the upper and lower bottom surfaces, which is very difficult to package.
