Frequently Asked Questions
What is a solar PV commissioning checklist?
A solar PV commissioning checklist ensures systematic verification of all photovoltaic system components — modules, strings, DC wiring, inverter, AC connection, protection, and metering — before grid connection. It follows IEC 62446 (grid-connected PV) and NEC Article 690 (solar photovoltaic systems) requirements.
What tests should solar PV commissioning include?
Key tests include module visual inspection (micro-cracks, hot spots, snail trails), string Voc and Isc measurements compared to STC ratings, polarity verification, DC insulation resistance (minimum 1MΩ × system voltage), inverter parameter setup, anti-islanding protection test, and IR thermography baseline for future comparison.
What Voc and Isc values are acceptable during PV commissioning?
String Voc should be within ±5% of the calculated value (modules × rated Voc, corrected for temperature). String Isc should be within ±5% of the module rated Isc. Significant deviations indicate faulty modules, shading issues, or wiring errors. IEC 62446 requires documenting these measurements.
