What are the requirements for large PV power plants?
Large PV power plants (i.e., greater than 20 MW at the utility interconnection) that provide power into the bulk power system must comply with standards related to reliability and adequacy promulgated by authorities such as NERC and the Federal Energy Regulatory Commission (FERC).
When should a PV O&M plan be considered?
The PV O&M plan should be considered within the context of the performance period required for a residential or commercial PV system to generate a sufficient return on investment (ROI). The PV O&M life cycle begins with planning and system design. The life cycle ends with provision for decommissioning or disposal of the system.
Should a PV O&M plan include decommissioning?
Include decommissioning in the PV O&M plan and/or asset management. The residential and small commercial O&M focus is on fleet performance goals rather than individual systems; meeting performance warranties of individual systems to meet customer satisfaction goals should be balanced against cost and cash-flow optimization.
Why should a roof maintenance provider meet with a PV O&M team?
Failure to provide 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.
