FAQ Helpdesk

Frequently Asked Questions

What is solar PV testing?

Solar PV testing involves verifying electrical safety (ground continuity, insulation resistance) and operational performance (open circuit voltage $V_{oc}$, short circuit current $I_{sc}$, and I-V curve tracing) of photovoltaic panels and strings per IEC 62446 standards before grid connection and during routine O&M.

What standards apply to solar PV testing?

The primary international standard is IEC 62446 (Parts 1 & 2), which outlines documentation, commissioning tests, and inspection requirements for grid-connected photovoltaic systems. It mandates Category 1 safety tests ($R_{ins}, V_{oc}, I_{sc}$) and Category 2 performance tests (I-V curve tracing).

Why is I-V curve tracing important?

I-V curve tracing provides a comprehensive diagnostic fingerprint of a solar PV module or string. It helps pinpoint degradation, partial shading, broken bypass diodes, high series resistance, or hotspot damage that standard single-point $V_{oc}$ and $I_{sc}$ measurements cannot detect.

How often should solar PV arrays be tested?

Full Category 1 safety and performance commissioning tests should be performed immediately upon system installation before handover. In addition, routine O&M inspections and insulation testing should be conducted annually or bi-annually depending on regional grid operator requirements and environmental conditions.
