Abstract

The invention relates to the technical field of double-glass photovoltaic components and particularly discloses a double-glass component temperature impact resistance test method. The method comprisesthe steps that a double-glass component sample is subject to appearance checking, EL testing and power testing; after a current is introduced into the double-glass component sample for heating treatment, shock cooling treatment is performed; and the double-glass component sample obtained after treatment is subject to appearance checking, EL testing and power testing again, and the testing resultis compared with a testing result of the double-glass component sample before treatment. Through the double-glass component temperature impact resistance test method, operation is easy, time is short,cost is low, and the testing result is more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a method for testing the temperature shock resistance of a double-glass module. Background technique [0002] In recent years, energy problems have become more and more serious, and the world has begun to develop and utilize new energy sources. As a new type of green renewable energy, solar energy has the advantages of large reserves, long life and no pollution, and has become the most promising new energy. The application of solar energy to power generation has become the focus of widespread attention. Light energy is a high-grade energy that is more convenient to use, transmit and distribute. Converting solar energy into electrical energy is an important technical basis for large-scale utilization of solar energy. Among them, photovoltaic modules are the core part of the photovoltaic power generation system and the most valuable part of the photovoltaic power gene...
