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.
For charging a 400Ah battery, a recommended solar panel size is approximately 800 to 1,600 watts. This recommendation depends on the daily power requirements and sunlight availability.
