What is operation & maintenance (O&M) of photovoltaic (PV) systems?

This guide considers Operation and Maintenance (O&M) of photovoltaic (PV) systems with the goal of reducing the cost of O&M and increasing its effectiveness. Reported O&M costs vary widely, and a more standardized approach to planning and delivering O&M can make costs more predictable.

Why is PV system operations a growing field?

PV system operations is a growing field because increasing PV penetration into the larger utility system, and an emerging market for ancillary services (e.g., dispatch of storage, sourcing reactive power, curtailment of output) require more system interaction on an ongoing basis.

How do I manage a fleet of PV systems?

Operating and maintaining a fleet of PV systems requires active resource management and data acquisition and analysis by the asset and operation manager(s). Outsource the service to a specialized third-party O&M provider.

What should a documented PV system O&M plan include?

A documented PV system O&M plan for a system or fleet of systems should include the following (depending on system size, complexity, and investment): List of responsible-party contact information including site owner and offtaker of power, utility, local jurisdiction, local landowner, as well as emergency numbers.

Why should a roof maintenance provider meet with a PV O&M team?

Failure to provide for maintenance of a roof system may result in roof-system failure, thereby necessitating PV system removal for roof repair/replacement, which is bad for the prospects of the PV system. By meeting, the roof maintenance provider can share particular areas of concern with the PV O&M team, and vice versa.

Can a PV system be exposed to sunlight?

Wires, plastic wire-ties, or grommets/bushings are exposed to sunlight. Even products listed for direct UV exposure will show degradation over the long life of a PV system and require eventual replacement.
