Solar battery module and assembly method thereof

Abstract

The invention provides a solar battery module which comprises tempered glass and battery pieces and further comprises a hydrophilic coating arranged on the surface of one side of the tempered glass far away from the battery pieces and capable of absorbing water. An assembly method of the solar battery module is further provided. The assembly method includes welding the battery pieces into a battery string, laying the battery string into a battery panel, conducting EL test on the battery panel, laminating the battery panel to obtain a solidified battery panel, trimming the solidified battery panel, conducting EL test on the solidified battery panel, arranging the hydrophilic coating on the surface of the tempered glass, assembling a frame on the solidified battery panel, welding a wiring box on the solidified battery panel and detecting the solidified battery panel. Due to the fact that the hydrophilic coating is arranged on the tempered glass, the solar battery module does not need to be cleaned manually, and damage to the solar battery pack is avoided.

Description

technical field [0001] The present invention relates to the technical field of solar cells, more specifically, to a solar cell assembly, and also relates to an assembly method suitable for the above-mentioned solar cell assembly. Background technique [0002] The solar cell module is installed outdoors and exposed to the air for a long time. Affected by the atmosphere and wind and sand, a layer of dust and dirt is often deposited on the tempered glass on the top layer of the solar cell module, which affects the light transmittance of the tempered glass and reduces The intensity of sunlight on the battery sheet is affected, which affects the power generation efficiency of the battery sheet. [0003] In the prior art, in order to avoid the above-mentioned problems, the measures taken are to manually clean the tempered glass on the top layer of the solar cell module. During the cleaning process, the operator needs to step on the solar cell module to clean the tempered glass. T...

Problems solved by technology

[0002] The solar cell module is installed outdoors and exposed to the air for a long time. Affected by the atmosphere and wind and sand, a layer of dust and dirt is often deposited on the tempered glass on the top layer of the solar cell module, which affects the light transmittance of the tempered glass and reduces The intensity of sunlight on the battery sheet is affected, which affects the power generation efficiency of the battery sheet

[0003] In the prior art, in order to avoid the above-mentioned problems, the measures taken are to manually clean the tempered glass on the top layer of the solar cell module. During the cleaning process, the operator needs to step on the solar cell module to clean the tempered glass. However, this cleaning method will cause certain damage to the solar cell modules due to the trampling of the operator during the operation, and there is a risk of damaging the solar cell modules

In addition, this manual cleaning method is not only time-consuming and labor-intensive, but also has high cleaning costs. It also has the disadvantages of insufficient cleaning and untimely cleaning, which cannot effectively reduce the impact of dust or dirt on the power generation efficiency of solar cell modules.
