PID is essentially a voltage leak. It happens when a difference in electrical potential between the solar cells and other panel materials, like the frame, causes ions to migrate. This can create a kind of "shadow" or dark patch on the panel.
Distributed photovoltaic (PV) generation has become a key driver of the energy transition in China, with its electricity generation in 2024 reaching 346. 2 billion kilowatt-hours (kWh), accounting for 41 percent of total PV output, according to data released by the National Energy.
