Embodiment 1

[0014] The first preferred embodiment of the present invention provides a method for testing the peeling force of photovoltaic modules, comprising the following steps:

[0015] Step 1: Sampling, shine a light source on the photovoltaic module, select a backsheet with a width of 1 to 10 cm from the photovoltaic module, and peel off the backsheet from the photovoltaic module by 2 to 5 cm. In this embodiment, a backsheet with a width of 5 cm is preferred. Peel off the photovoltaic module by 4cm;

[0016] Step 2, place the photovoltaic module on the test bench, fix the photovoltaic module with the photovoltaic module fixing parts, and at the same time, use the material chuck of the test tensile part to clamp the stripped end of the back plate and the material hook of the test tensile part Hook one end of the metal frame of the photovoltaic module;

[0017] Step 3: Peel the backsheet upwards with the test tensile piece. When the test tensile piece is stretched upwards, the materia...

Embodiment 2

[0021] The second preferred embodiment of the present invention provides a method for testing the peeling force of photovoltaic modules, comprising the following steps:

[0022] Step 1: Sampling, shine a light source on the photovoltaic module, select glass with a width of 1-10 cm from the photovoltaic module, and peel the glass out of the photovoltaic module for 2-5 cm.

Abstract

The invention relates to a method for testing a release force of a photovoltaic module. The method comprises the following steps: 1, sampling, selecting a back plate or glass of the photovoltaic module, and releasing the back plate or the glass from the photovoltaic module by 2-5 cm; 2, putting the photovoltaic module onto a test worktable, fixing the photovoltaic module by a photovoltaic module fixing piece, clamping the release end of the back plate or the glass by a material clamping head of a stretching test part, and hooking one end of a metal frame of the photovoltaic module by a material hook of the stretching test part; 3, releasing the back plate or the glass upwards by the stretching test part, and finally testing the release force of the back plate or the glass of the photovoltaic module by the weighing sensor. According to the method, the back plate or the glass of the photovoltaic module is selected as a tested photovoltaic module material and is released by the stretching test part, and the release force of the tested photovoltaic module material is tested through the weighing sensor, thereby guaranteeing product quality.

Description

technical field [0001] The invention relates to the field of testing solar photovoltaic modules, in particular to a method for testing the peeling force of photovoltaic modules. Background technique [0002] At present, solar photovoltaic modules include laminated parts and metal frames arranged at both ends of the laminated parts. The laminated parts include cells, glass and back plates respectively arranged on both sides of the cells. It is provided with an EVA layer. [0003] Solar photovoltaic modules are the core part of the solar power generation system, and also 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. With the development of new energy technologies, photovoltaic modules are increasingly used in various products, which makes the performance testing of photovoltaic modules particularly important. The peeling force between the l...
