Convenient-to-maintain solar module structure

Abstract

The invention discloses a convenient-to-maintain solar module structure, which comprises a cuboid framework. The cuboid framework is internally provided with a silicon wafer cell; the upper surface ofthe silicon wafer cell is bonded with a glass plate by an upper EVA adhesive layer and the lower surface is bonded with a back plate through a lower EVA adhesive layer; the bottom part of the back plate is provided with a wiring box connected with the silicon wafer cell; the lower surface of the silicon wafer cell is provided with a groove; a supporting block is fixed in the groove; and the end part of the supporting block is connected with the lower EVA adhesive layer. Through converting bonding between the silicon wafer cell and the EVA adhesive layer to bonding between the supporting blockand the EVA adhesive layer, the surface of the silicon wafer cell can be well protected, the contact surface between the supporting block and the EVA adhesive layer only needs to be stripped in the case of disassembly, the operation is simple and easy, the silicon wafer cell is not damaged, and the service life is improved greatly.

Description

technical field [0001] The invention belongs to the field of solar energy application equipment, and in particular relates to a solar component structure with convenient maintenance. Background technique [0002] A single solar cell cannot be directly used as a power source. As a power supply, several single cells must be connected in series and parallel and tightly packed into components. Solar cell modules (also called solar panels, photovoltaic modules) are the core part of the solar power generation system and the most important part of the solar power generation system. Its function is to convert the solar energy into electrical energy, or store it into the battery, or promote work load. The quality and cost of solar cell components will directly determine the quality and cost of the entire system. Solar cell modules are generally composed of high-efficiency crystalline silicon solar cells, ultra-white tempered glass, EVA, transparent TPT backplane and aluminum alloy...

AI Technical Summary

Problems solved by technology

However, once there is a problem with the silicon wafer battery and needs to be inspected or replaced, it is difficult to separate it from the entire structure or cause structural damage when it is separated due to the fact that the upper and lower surfaces are bonded with EVA.
