How to maintain a solar facility?
Preventive Maintenance 1 Visual inspection of Solar Facility’s general site conditions, PV arrays, electrical equipment, mounting structure, fence, shading, trackers, vegetation, animal damage, erosion, corrosion, and discolored panels. 1x per year 2
Why should you track energy availability in a PV operation contract?
Tracking this availability (or unavailability) provides transparency into the equipment reliability state to all parties involved in an O&M services contract. In most PV operation contracts, energy will be the driving factor of whether the system is operating as expected.
Why is energy availability important in assessing PV systems?
Both energy and availability are necessary metrics for assessing PV systems. If the stakeholders involved in a contract are most interested in energy production, and if the contract holds parties responsible for energy production, then it is crucial that energy losses associated with unavailability and system performance are accounted for.
What is PV maintenance?
Information such as electrical drawings, part specifications, manuals, performance information, and records must be deliberately maintained and properly filed/catalogued. PV maintenance includes the following four types of maintenance procedures: 1. Administration of maintenance
Where can I find a report on photovoltaic system performance?
IEC 61724-2 Photovoltaic system performance - Part 2: Capacity evaluation method IEC TS 61724-3 Photovoltaic system performance - Part 3: Energy evaluation method 138 This report is available at no cost from the National Renewable Energy Laboratory (NREL) at IEC 63019 Information Model for Availability (pending).
