Latest version of photovoltaic panel maintenance manual

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.

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.

What is the IEA photovoltaic power systems programme?

The IEA Photovoltaic Power Systems Programme (IEA PVPS) is one of the TCPs within the IEA and was established in 1993. The mission of the programme is to “enhance the international collaborative efforts which facilitate the role of photovoltaic solar energy as a cornerstone in the transition to sustainable energy systems.”

Do photovoltaics need a lot of maintenance?

One of the factors behind the success of photovoltaics is its lower maintenance requirements compared to other types of electricity generation. However, low maintenance does not mean that no maintenance is required.

What should be included in an O&M programme of a PV plant?

An O&M programme of a PV plant thus should foresee a certain number of spare part stocks of the plant equipment, especially the key ones such as PV modules, inverters, tracker components (if applicable) and transform-ers.

How long should a PV installation warranty last?

Ensure at the conclusion of an installer warranty, which may be only 1–10 years, that any equipment warranties (which may be as long as 25 years for PV modules) transfer or are designated to the responsible O&M provider. Current status of KPIs should be available to all parties to the performance contract, both present values and trends over time.
