Method for detecting long-term potential influence of mechanical load on performance of photovoltaic module

The invention discloses a method for detecting the long-term potential influence of a mechanical load on the performance of a photovoltaic module. The method comprises the following steps: 1) selecting a module which is completely the same as a test module as a comparison module; 2) applying a mechanical load to the test module, and then performing appearance, maximum power and electroluminescencetests on the test module and the comparison module; 3) performing the same accelerated aging test on the test module and the comparison module, and then performing appearance, maximum power and electroluminescence tests; 4) analyzing electroluminescent image change conditions of the test module and the comparison module after the accelerated aging test; and 5) calculating and analyzing the powerattenuation condition of the test module and the comparison module after the accelerated aging test. The influence of environmental factors on the performance of the photovoltaic module in the long-term operation process is si
