Problems solved by technology

However, for example, turning over the back panel at the outlet hole to increase the distance between the wire and the metal layer of the back panel will increase the size of the outlet hole on the back panel, making it easy for water vapor to enter the solar energy through the outlet hole. module, resulting in solar module damage and failure

Abstract

The invention discloses a solar module, and the module comprises a back plate, a light transmission substrate, a plurality of solar cells, a plurality of auxiliary wires, a sealing layer, a plurality of main wires, and a water-resisting insulating layer. The back plate is provided with a wire outgoing hole. The solar cell is disposed between the back plate and the light transmission substrate. The auxiliary wires are connected with the solar cells and are gathered to the main wires. The sealing layer is disposed between the back plate and the light transmission substrate, and covers the solar cells and the auxiliary wires. The main wires pass through the sealing layer and the wire outgoing holes to be connected to a junction box. The water-resisting insulating layer is embedded in a region, between the back plate and the solar cell, in the sealing layer, and is corresponding to the position of the wire outgoing hole, thereby enabling the projection of the water-resisting insulating layer towards the back plate to at least cover the wire outgoing hole.

Description

technical field [0001] The present invention relates to a solar module, and in particular to a solar module with better water resistance. Background technique [0002] With the rising awareness of environmental protection, the concept of energy saving and carbon reduction has gradually attracted people's attention. The development and utilization of renewable energy has become the focus of active development by countries all over the world. Among the renewable energy sources, since sunlight is available everywhere, and unlike other energy sources (such as petrochemical energy, nuclear energy), which generally pollute the earth, solar energy and various devices that can convert sunlight into electrical energy are currently promising stars industry. [0003] Generally speaking, the backplane of the solar module has a hole for the wires connected to the solar cells to pass through the backplane. U.S. Patent Nos. US8461450, US2010 / 0229937 and US2010 / 0236623 disclose that insul...
