Best Practices in Photovoltaic System Operations and Maintenance: 3rd Edition – UNDER REVIEW
A third edition of the guide is under development and will include issues related to energy storage systems. Thank you to those of you who have shared comments and additions thus far.
The latest draft is below. Sections that saw the most change between the 2nd and 3rd editions have highlighted section titles (in the table of contents and throughout the document). That said, feedback on any other section is also welcome.
About the Workgroup: The Best Practices for Installation, Operation and Maintenance of PV and Storage Systems (PV O&M Best Practices Working Group) is a collaborative industry stakeholder group led by NREL, Sandia National Labs, and the SunSpec Alliance under U.S. Department of Energy SunShot Initiative. The working group consists of a broad range of professionals from several O&M-related industries, including investors, engineers, O&M service providers, legal professionals, and others. The principal aim of this working group is to mitigate uncertainty in O&M costs and practices through data analysis and a consensus-making process. The main objective is to reduce O&M costs and improve PV project performance and financing.
Group Leader: Andy Walker, National Renewable Energy Laboratory (NREL)

NREL, Sandia and SunSpec PV O&M Collaborative Working Group Background:
The “PV O&M Collaborative Working Group,” a stakeholder body convened by NREL, Sandia National Labs, and the SunSpec Alliance under U.S. Department of Energy sponsorship. The working group will consist of a broad range of professionals from several O&M-related industries, including financiers and investors, independent engineers, O&M services providers, legal professionals, and others. The principal aim of this collaborative is to mitigate uncertainty in O&M costs and practices through “bankable” data and a consensus-making process, ultimately reducing O&M costs and improving PV project performance and financeability.
The PV O&M Collaborative represents the integration and extension of the Solar Access to Public Capital (SAPC) Working Group and Sandia National Laboratory’s PV O&M Technical Working Groups. Last year these efforts yielded a prototype O&M cost model, an interim “best practices “ guidebook that incorporated the insights of over 40 industry professionals, a best practice for developing availability guarantees, and PV project performance and reliability simulations and databases.
The newly combined (financial and technical) working group will refine these assets to optimize O&M service provisions and resulting performance and increase their impact through on-line access. Robust and data-driven O&M practices will improve project performance and provide cost certainty. These practices can reduce perceived risk for financiers and facilitate the development of secondary markets for solar assets, such as solar asset-backed securities and project acquisitions. Additionally, recommendations developed by the PV O&M Working Group will be tendered for adoption to the relevant standards bodies, including IEC, ANSI, and ASTM through our consultant Roger Hill.
To achieve these goals, the PV O&M Working Group will undertake the following tasks and activities:
- Update and refine Best Practices in PV Systems Operations and Maintenance
- Develop standards for O&M scopes of service, contract language, and costs
- Expand the oSPARC performance database to include key performance indicators and storage analysis capabilities
- Transition the Excel-based O&M Cost Model to an on-line implementation, and incorporate failure simulations and distributions from PVROM and RPM
- Develop additional technical specifications and calculations for availability guarantees
