All solar panels experience efficiency loss over time, known as degradation. Factors like UV radiation, extreme temperatures, and moisture exposure contribute to this gradual decline. Through detailed performance analysis, we compare the system’s current output against expected values to detect underperformance. Advanced techniques like IV curve tracing and electroluminescence imaging allow us to pinpoint aging-related issues. Our degradation checks help ensure that energy losses remain within acceptable limits, extending the system’s effective lifespan.
