BS PD IEC/TS 62446-3 – Photovoltaic (PV) systems. Requirements for testing, documentation and maintenance

BS PD IEC/TS 62446-3:2017 defines outdoor thermographic (infrared) inspection of PV modulesand plants in operation. The inspection can include cables, contacts, fuses, switches,inverters, and batteries. This inspection supports the preventive maintenance for fireprotection, the availability of the system for power production, and the inspection of thequality of the PV modules. Included in this document are the requirements for themeasurement equipment, ambient conditions, inspection procedure, inspection report,personnel qualification and a matrix for thermal abnormalities as a guideline for theinspection.

This document defines outdoor thermography on photovoltaic (PV) modules and Balance-ofsystem(BOS) components of PV power plants in operation, using passive techniques(standard system operating conditions under natural sunlight, without any external power orirradiation sources). IEC 60904-12-1 covers general methods for laboratory or production-linePV module thermographic imaging but not the specific details that are most relevant tooutdoor imaging of operational power plants including BOS components.
