Abstract: Taking the greenhouse power station in Pingyuan as the project background, after the power station has been put into
use for more than 3 years, the module PID phenomenon has appeared one after another. Statistics show that there are 59 branches
with PID phenomenon. After measuring the actual voltage and current, the problem was found, the module was repaired to restore
the output current value, and the photovoltaic power generation met the requirements for power generation.

Key words: PID phenomenon; photovoltaic power generation; generating capacity
