What is PID ?

Potential-Induced Degradation (PID) is a common phenomenon causing PV panels to lose power generation by up to 80%. Power reduction can occur within days or weeks after installation. The PID process in the PV panel may grow very rapidly and in the shortest...

Smart data analytics: The urge to optimize PV plant performance is a natural one, and something every good EPC worth their salt should be thinking of from day one. And while post-installation monitoring and anal...

Utility Scale PV Power Plants operate at high system voltages ranging from 500 Vdc to 1000 Vdc. It has been observed that this high potential can lead to or accelerate module degradation through multiple factors. Such factors may result in conditions such as potential...

Potential-induced degradation: Even though many module manufacturers are now promoting PID-resistant modules, the problem of potential-induced degradation remains unsolved. Three experts explain why not all tests can be trusted, and how to detect and reduce the effect.
