Two effects affecting the normal operation of photovoltaic modules

Photovoltaic modules are the most important equipment in photovoltaic power generation. In the process of daily installation, operation and maintenance, if there are special circumstances, it will cause the hot spot effect and potential induced attenuation effect (PID) of photovoltaic modules and cause losses to the majority of owners. Therefore, we should pay attention to controlling the photovoltaic power station during installation and daily maintenance of the power station to avoid these two effects.
