Solar I-V curve tracing: what it is, what it reveals, and why it's important for PV arrays.

This full interview with Stephen San Juan, a solar training and renewable energy safety expert, gets into the subject of I-V curve tracing. He explains what an I-V curve tracing is, what it reveals about a PV array, and why regular testing is so important, especially for large PV systems.

I-V Curve Tracing is an essential method for evaluating the performance and health of a solar PV array—whether you're testing individual modules or full strings. In this video, we break down how I-V Curve Tracing works by comparing maximum potential current to voltage, and how the resulting curve helps you diagnose issues and ensure optimal system performance
