Identifying Potential-Induced Degradation (PID) in Solar Modules With Drone Thermography
Potential induced degradation (PID) is an issue that all solar stakeholders, especially owners and O&Ms should be taking seriously even if it only affects a small minority of modules.Given the substantial time and expense associated with testing individual modules or strings using IV-curve tracing or electroluminescence testing, operators can use drone thermography to identify modules potentially affected by PID in a timely and cost-effective manner. In this article we will explain why it is important to identify PID in solar modules.
