What Is PID?
A solar installation for your home is a great way to future proof your energy bill against rising prices.
But to make sure your solar panels can last a long time, you need to watch out for some common solar panel defects that can ruin the overall energy production of your system.
One of such defects is PID or Potential Induced Degradation.
What is Potential Induced Degradation?
PID is a solar cell defect caused by the high voltage potential between a solar module and the ground.
The combination of long solar panel strings and grounding the panels’ aluminium frames creates a high voltage difference between solar cells and the frame, which can cause the solar cells to deteriorate due to unwanted charge carrier movements.
Since the string voltage of a rooftop solar system can range from a few hundred volts on a small roof, to a thousand volts in a large project, PID effect is a significant cause for power degradation in big rooftop installations.
WINAICO’s solar modules are designed with anti-PID technology in mind to make sure they work harder and longer on your rooftop installation.
