Problems solved by technology
However, in this invention, the unframed components, that is, "laminates" are simply placed on the transmission chain for operation, and the laminates are prone to large deformation due to no frame support, resulting in inaccurate electrical performance test results. Accurate, and bring the risk of cell cracking to the product
The width of the transmission chain may also prevent the uniform distribution of light to the entire surface of the product, thereby affecting the accuracy of test results

Embodiment Construction
[0027] In order to make the content of the present invention easier to be understood clearly, the following further describes the present invention in detail based on specific embodiments in conjunction with the accompanying drawings.
[0028] Such as Figure 1~6 As shown, a method for testing the electrical performance of a photovoltaic module is set before the frame of the photovoltaic module 5 is installed. The steps of the method are as follows:
[0029] a) Drive the photovoltaic module 5 to the test position;
[0030] b) Adjust the levelness of the photovoltaic module 5 at the test site to make the light-receiving surface of the photovoltaic module 5 level, and ensure that the light-receiving surface of the photovoltaic module 5 is at the same height as the light-receiving surface of the standard sheet;
[0031] c) From the light-receiving surface side of the photovoltaic module 5 through a solar simulator 1 to irradiate the light-receiving surface of the photovoltaic module 5 wi...

The invention discloses a method for testing the electrical performance of a photovoltaic module. The method is arranged before the frame of the photovoltaic module is installed. The steps of the method are as follows: a) driving the photovoltaic module to a test position; b) adjusting the levelness of the photovoltaic module on the test position , so that the light-receiving surface of the photovoltaic module is in a horizontal state, and ensure that the light-receiving surface of the photovoltaic module is at the same height as the light-receiving surface of the standard sheet; c) from the light-receiving surface side of the photovoltaic module through a solar simulator Irradiate simulated light and avoid the light-receiving side of the photovoltaic module from being blocked, and then use the lead wire test fixture to clamp the positive and negative lead wires of the photovoltaic module from the backlight side of the photovoltaic module respectively, so as to test the electrical performance of the photovoltaic module . The invention can not only realize the non-destructive and rapid test of the electrical performance of the photovoltaic module, avoid the phenomenon of hidden cracks and fragments of the photovoltaic module, but also improve the accuracy of the electrical performance test of the photovoltaic module.
Description
Technical field [0001] The invention relates to a method for testing the electrical performance of photovoltaic components, belonging to the technical field of photovoltaic testing. Background technique [0002] At present, solar energy as a clean energy source has received great attention in recent years. Photovoltaic manufacturers and researchers are trying to continuously improve the performance and quality of photovoltaic products through process technology optimization and production process improvement. [0003] The electrical performance test of photovoltaic products is a necessary link to confirm product performance and quality in product production. How to complete the test accurately, conveniently, non-destructively and quickly is an important issue in the manufacturing process of photovoltaic products. [0004] At present, there are two main ways to test the electrical performance of photovoltaic products: one is to test through a solar simulator after the module is frame...
