Summary At present, the power attenuation problem in the solar panel system application field is mainly due to the decrease in output power caused by the quality of the components.
The external environmental factors cause the destructive influence of the solar panel, causing the power of the module to be attenuated or even damaged.
During the later use of photovoltaic power plants, because most of the installation locations of the power plants are outdoors, they will encounter various weather and environmental conditions. Among them, the hot spot effect is the most likely factor to reduce the power of the modules.
The hot spot effect caused by external factors mainly refers to the solar cell modules being irradiated by the sun, because some of the modules are blocked by dark clouds or leaves, etc., so that the covered part of the module heats up much more than the uncovered part, causing the temperature to be too high Dark spots of burnout appear.
At present, the power attenuation problem in the solar panel system application field is mainly due to the decrease in output power caused by the quality of the components. There is no way to avoid power attenuation in this situation in the later application process. What we should do more is Control the quality in the production process, improve the production process, and improve the product quality.
