1 Introduction 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.
Therefore, maintenance management is essential for reliable and effective operation of PV power plants, ensuring uninterrupted system operation and minimizing downtime. Compared to well-established technologies such as hydro, thermal, and wind, the O&M processes for PV systems are not yet fully structured in many operating companies .
What are NREL's best practices at the end of photovoltaic system performance period?
NREL's Best Practices at the End of the Photovoltaic System Performance Period report includes recommendations for system owners, asset managers, and industry service providers regarding the handling and disposal of waste, including reuse and recycling of PV modules and other components as a way to reduce environmental impact.
The definition of the PV system to be maintained shall include PV modules, the support structure, disconnects, inverter(s), monitoring equipment, and all other appurtenances to make the PV system complete, grid- connected, and operational. 104
The article outlines maintenance procedures for photovoltaic systems, including inverters, charge controllers, PV arrays, and battery banks. This capacity-building manual was developed as part of the SESA project – Smart Energy Solution for Africa, funded by Research & Innovation. . This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www. National Renewable Energy Laboratory, Sandia National Laboratory, SunSpec Alliance, and the SunShot National Laboratory Multiyear Partnership (SuNLaMP) PV O&M Best Practices. . After solar energy arrays are installed, they must undergo operations and maintenance (O&M) to function properly and meet energy production targets over the lifecycle of the solar system and extend its life. O&M for a system can be provi ed by the solar installer, a third-party company or managed in-house.
