This Part 2 of IEC 62446 describes basic preventive, corrective, and performance related maintenance requirements and recommendations for grid-connected PV systems.  The maintenance procedures cover:

Basic upkeep of the system components and connections for reliability, safety and fire prevention;

Measures for corrective maintenance and troubleshooting

Worker safety

The standard also addresses maintenance items for maximizing anticipated performance such as module washing and upkeep of vegetation. Special considerations unique to rooftop or ground-mounted systems are summarized. This standard does not cover off-grid systems or systems that include batteries or other energy storage, however parts may be applicable to the PV circuits of those systems.

The confirmation of a system’s compliance with the appropriate design and installation standards is covered in Part 1 and takes place during initial project commissioning. 

Maintenance of PV systems is often lumped into the catch-all term operations and maintenance (O&M.) This standard does not address business or management operational processes (e.g. forecasting, utility pricing incentives, etc.) or other considerations driven by factors outside of basic system working condition, safety and performance.

This part of IEC 60904 sets the requirements for calibration procedures intended to establish the traceability of photovoltaic (PV) reference devices to SI units as required by IEC 60904-2.

This standard applies to PV reference devices that are used to measure the irradiance of natural or simulated sunlight for the purpose of quantifying the performance of PV devices. The use of a PV reference device is required in the application of 60904-1 and 60904-3.

This standard has been written with single-junction PV reference devices in mind, in particular crystalline Silicon. However, the main part of the standard is sufficiently general to include other single-junction technologies.
