Solar panel quality appraisal

Solar energy is a new type of clean energy that is both common and environmentally friendly. In order to realize the utilization of solar energy, solar panels came into being.
solar panel is a pair of devices that respond to light and can convert light energy into electricity. There are many kinds of materials that can produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium indium copper, etc. Their power generation principles are basically the same. Now, a crystal is used as an example to describe the photovoltaic power generation process. P-type crystalline silicon can be obtained by doping phosphorus to form N-type silicon, forming a PN junction.
In solar panel quality appraisal cases, Zhongke Testing can provide solar panel quality appraisal services.

A solar panel used by a power generation company caught fire, and three of the solar panels suffered varying degrees of damage. The power generation company made a claim with the insurance company. In order to confirm the cause of the solar panel fire and the quality of other solar panels, both parties entrusted an appraisal agency to conduct quality appraisal.
appraisal analysis results: The
appraisal analysis expert group discussed the relevant information and on-site investigation of the solar panel involved and made a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
The solar panel involved in the case had various degrees of hidden cracks, scratches, missing corners and other problems, and the failure rate was high, which was also the cause of the fire.
