Problems solved by technology

[0003] During the production of photovoltaic modules, the tolerance of photovoltaic modules needs to be tested, but the existing detection devices have fewer simulation scenarios, simple functions, and poor detection results. They cannot simulate the process of photovoltaic modules during transmission, nor can they simulate After the installation of the photovoltaic module after repeated vibrations, it is impossible to simulate the situation of the photovoltaic module being hit, nor can it simulate the situation when the photovoltaic module is dropped. Therefore, we propose a photovoltaic module tolerance performance test system and testing process. to solve the above-mentioned problems

Abstract

The invention discloses a system and a process for testing tolerance performance of a photovoltaic module. The system comprises a test box, the inner walls of the two sides of the test box are fixedly connected with fixed boxes, one sides of the fixed boxes are slidably connected with a vibration box, one side of the vibration box is fixedly connected with a triangular block, the inner wall of one side of the test box is fixedly connected with a fourth fixed plate, a lower baffle is slidably connected to the top of the fourth fixed plate, a discharging opening is formed in the lower baffle, an upper baffle is slidably connected to the inner wall of the top of the test box, and a second baffle is fixedly connected to one end of the upper baffle. The invention also discloses a using method. The system has the beneficial effects that the system is compact in structure, can simulate the process of the photovoltaic module during transmission, the condition of the photovoltaic module after being installed and vibrated for multiple times, the condition that the photovoltaic module is hit and the condition that the photovoltaic module falls off, and is more comprehensive in multi-scene simulation test and detection and convenient to use.

Description

technical field [0001] The invention relates to the technical field of photovoltaic component testing, in particular to a photovoltaic component endurance performance testing system and a testing process. Background technique [0002] Photovoltaic modules are composed of high-efficiency crystalline silicon solar cells, ultra-white cloth-textured tempered glass, EVA, transparent TPT backplane and aluminum alloy frame. It has the characteristics of long service life and strong mechanical resistance to external force. Due to the low output voltage of monolithic photovoltaics and the fact that the electrodes of unpackaged cells are easy to fall off due to the influence of the environment, a certain number of monolithic cells must be connected in series or in parallel. It is sealed into photovoltaic modules to avoid corrosion of battery electrodes and interconnecting lines. In addition, packaging also avoids battery fragmentation and facilitates outdoor installation. The quality ...
