Field Study of Photovoltaic Systems with Anti-Potential-Induced-Degradation Mechanism: UVF, EL, and Performance Ratio Investigations

The potential-induced degradation (PID) of photovoltaic (PV) modules is one the most extreme types in PV modules, where PID-affected can result an almost 25% power reduction. Understanding how module defects impact PID key to reducing issue. Therefore, this work investigates anti-PID inverter on throughout three years field operating conditions. We used electroluminescence (EL), ultraviolet fluorescence (UVF), and thermography imaging explore varieties connected a string. It was discovered that string with could improve output by 5.8%. In addition, performance ratio (PR) equal 91.2% 87.8%, respectively, for strings without inverter.
