Embodiment

[0023] Example: A new type of concave photovoltaic module

[0024] Such as Figure 1-4 As shown, the photovoltaic module 1 includes a front panel, an encapsulation structure, solar cells, a back panel and a junction box, the solar cells and the back panel are stacked, and the junction box is connected to the solar panel.

[0025] The front plate is made of light-transmitting tempered glass, and the surface stress of the light-transmitting tempered glass is above 40Mpa after tempering. The packaging structure is composed of multiple POE layers stacked in a 1+1 stacking manner. The solar cell is composed of multiple strings of cell groups connected in series, and each string of cell groups includes several cells. In this embodiment, each , the solar panel is composed of 6 strings of battery slices in series, each string of battery slices includes 12 pieces of battery slices, in which, the distance between two adjacent battery slices is 2mm, and the distance between two adjacent...

Abstract

The invention relates to a novel concave photovoltaic module, comprising a front panel, an encapsulation structure, a solar cell sheet, a back panel and a junction box, wherein the solar cell sheet and the back panel are laminated and arranged, and the junction box is connected with the solar cell panel. The invention also relates to a novel concave photovoltaic module, comprising a front panel, an encapsulation structure, a solar cell sheet, a back panel and a junction box. The invention aims at the problem that the traditional photovoltaic module with a frame fails to utilize light effectively, The front plate and the back plate of the photovoltaic module are made of tempered glass, the mounting fixture has a certain height, and there is no support in the middle of the fixture. When thephotovoltaic module is placed in the mounting fixture, the photovoltaic module is naturally concave to form a concave surface when the photovoltaic module is mounted due to the bendable characteristics of the double-glass module, so that the light incident amount is increased, and the power generation amount is increased.

Description

technical field [0001] The invention belongs to the field of photovoltaics, and in particular relates to a novel sunken photovoltaic module. Background technique [0002] The contradiction between energy supply and demand in my country is becoming increasingly fierce. The new energy industry represented by photovoltaic power generation will take on the important task of solving energy problems. How to increase power generation is a long-term exploration problem. It is known that the original double-glass module structure is glass + packaging material + cell + packaging material + glass + aluminum frame. When installing this module, the surface of the module is always flat due to the support of the aluminum frame, but this does not improve light utilization. Rate. With the enhanced glass tempering process, Almaden double-glass modules are lighter and thinner than traditional double-glass modules, without the need for aluminum frames, and the impact resistance can also meet t...
