Dual-purpose testing equipment for reliability of photovoltaic module

Abstract

The invention discloses dual-purpose testing equipment for reliability of a photovoltaic module in the technical field of photovoltaic module testing, and the dual-purpose testing equipment comprises a base, a flexible photovoltaic module testing box is arranged on the left side of the top of the base, and a rigid photovoltaic module testing box is arranged on the right side of the top of the base. The top of the flexible photovoltaic module testing box and the top of the rigid photovoltaic module testing box are fixedly connected with a top plate, a fixing frame is arranged at the top of the top plate, fans are arranged at the two ends of the front side of the fixing frame, exhaust outlets of the two fans are communicated with an exhaust pipe, and with rotation of a gear, a thin plate on a swing plate can drive the flexible photovoltaic panel upwards by a certain distance, hot air at the bottom of the flexible photovoltaic panel is convenient to circulate; the bottom of the flexible photovoltaic panel is only in contact with part of the thin plate, the contact surface is small, the flexible photovoltaic panel is in full contact with test gas, and the test efficiency is improved. Therefore, when the temperature of the flexible photovoltaic module is adjusted through the test gas, the adjusting speed is high.

[0002] Photovoltaic modules include rigid photovoltaic modules and flexible photovoltaic modules. The main material for the packaging of rigid photovoltaic modules is rigid materials, which cannot be bent. The main material for the packaging of flexible photovoltaic modules is flexible materials, which can be bent. The reliability of photovoltaic modules It refers to whether rigid photovoltaic modules and flexible photovoltaic modules can work normally under different temperature environments. If both rigid photovoltaic modules and flexible photovoltaic modules can work normally and for a long time under different temperatures, it proves that their reliability is good. On the contrary, it proves that the reliability is poor. At present, when testing flexible photovoltaic modules, since flexible photovoltaic modules are prone to bending when they are placed obliquely, which will cause damage to the film layer of the battery, they are usually placed horizontally, which can Avoid the bending of flexible photovoltaic modules, but horizontal placement will result in a larger contact area between the flexible photovoltaic module and the supporting surface, which will lead to insufficient contact with the test gas, and then use the test gas to adjust the temperature on the flexible photovoltaic module. The regulation rate is slow, for this reason, we propose a dual-purpose test equipment for PV module reliability
