Problems solved by technology

[0003] At present, before installing the photovoltaic modules into the solar power generation system, it is generally just to simply test the power of the photovoltaic modules. Simulate the working state of photovoltaic modules, but only compare the power before and after illumination, so it is difficult to determine the level of power output of photovoltaic modules, and thus it is difficult to determine whether the intrinsic quality of photovoltaic modules is reliable

Abstract

The invention provides a damp heat test device and a method for a photovoltaic assembly. The device comprises a test box which simulates a damp heat environment and is provided with a photovoltaic assembly installation part for installing a tested photovoltaic assembly, and a power supply which is provided with a power supply terminal which supplies power to the photovoltaic assembly inside the test box. An outdoor extreme state is simulated in the test box when the photovoltaic assembly works in the damp heat environment, and meanwhile, a sustaining voltage equivalent to a solar power system is applied to the photovoltaic assembly to simulate the working state of the photovoltaic assembly in the power generation process, so that the damp heat test can be completed within a short time. The quality of the photovoltaic assembly is determined and the power generation quantity of the photovoltaic assembly is predicted by comparing power attenuation values before and after test. As the damp heat test device provided by the invention is simple in structure, the damp heat test device can be widely applied in actual production.

Description

technical field [0001] The invention relates to the field of manufacturing photovoltaic modules, in particular, to a damp heat test device and method for photovoltaic modules. Background technique [0002] The solar panel of the photovoltaic module is the core part of the solar power generation system, and it is also the most valuable part of the solar power generation system. Its function is to convert the solar energy into electrical energy, or store it into the battery, or promote work load. [0003] At present, before installing the photovoltaic modules into the solar power generation system, it is generally just to simply test the power of the photovoltaic modules. The working state of photovoltaic modules is simulated, but only the power before and after illumination is compared, so it is difficult to determine the level of power output of photovoltaic modules, and thus it is difficult to determine whether the intrinsic quality of photovoltaic modules is reliable.
