Abstract

The invention discloses an anti-explosion solar module with the rated power no larger than 5W. The anti-explosion solar module comprises a piece of tempered glass, EVA adhesive films, a solar battery piece, an insulation backboard, a connecting box, a PCB with a voltage-stabilizing current-limiting control circuit, and sealant. The two sides of the solar battery piece are provided with the preset layers of EVA adhesive films respectively, and the solar battery piece with the EVA adhesive films is placed between the tempered glass and the insulation backboard, the connecting box is arranged on the other side, opposite to one side provided with the EVA adhesive films, of the insulation backboard, the PCB with the voltage-stabilizing current-limiting control circuit is arranged in the connecting box which is sealed by the sealant, and the sealant and the EVA adhesive films are pasted together. The anti-explosion solar module with the rated power no larger than 5W meets the requirement of the GB-3836.4-2000 anti-explosion standard, and has the good anti-explosion function.

Description

technical field [0001] The invention relates to a solar module, in particular to an explosion-proof solar module with a rated power not exceeding 5W. Background technique [0002] Now the country vigorously advocates and encourages the use of new energy sources to achieve energy conservation, consumption reduction, and emission reduction. Therefore, wind energy and solar energy have gradually become the mainstream of alternative energy sources. At present, conventional solar modules are composed of high-transmittance tempered glass, solar cells, single-layer EVA film connected to both sides of the solar cells, insulating backplane and junction box, etc., without explosion-proof and related protection measures. Contents of the invention [0003] The object of the present invention is to provide an explosion-proof solar module with a rated power not exceeding 5W, which avoids sparks caused by load damage caused by the voltage and current generated by solar cells. [0004] I...
