Step five: Deliver the first phase of PV industry standards
Step six: Refine standards over time
Step seven: High performance PV standards
Benefits of O&M
Extend system lifetime; extend time period that the
system delivers revenue
Improve system availability; Reduce downtime; re-capture lost revenue
Reduce cost of providing O&M; directly affect project cost
Efficiency and degradation in performance; maintain energy delivery and associated revenue
Predictability of performance and O&M costs; reduce insurance and financing costs by reducing uncertainty related to lifetime, performance, and O&M costs

The Next Era in PV: Collaborative O&M Standards Development
Guide the Installation, Commissioning, Operation and Maintenance of Photovoltaic Systems (ICOMP, Provide standards for foundational metrics and processes, enable consistent delivery and operation of quality
photovoltaic systems over their useful life, define the integrated process for consistent system delivery throughout the lifecycle of reliable and effective PV systems.
IEC
Formation and operation of a new conformity assessment system under the management of the IEC Conformity Assessment Board (CAB). Agreement on priorities for new standard development.
High Performance PV
Develop highest level of PV Total “systems process” application and O&M training and experience, Raise the PV industry bar for Performance, Reliably and Optimization (PRO), begin and end with O&M
NREL
Deliver products related to PV system O&M that address the needs of securitization by the private financial market. These include OM Best Practice and market driven cost model.
SunSpec
Survey of best industry practices framework, investor care abouts, sample O&M contract terms, definition of key O&M terms, O&M cost survey and description of O&M cost elements in working model.
Sandia / EPRI
Improve PV system design, installation O&M Develop benchmark report on PVROM from active participants. fault and failure analysis, and preventative maintenance.
TUV
Detailed non-intrusive and intrusive evaluations of fielded PV systems for reliability, safety and durability; Identification of field failure modes and mechanisms; Accelerated testing for quality evaluations of fresh PV modules and materials
Engage with Industry to: Explain existing efforts being targeted Ensure gaps are identified and guide working groups Recruit participants for working group efforts
Document Developed with Industry participation
Sandia Technical O&M Working Group O&M Working Group coordination meeting on March 24,
2014. ASTM, Calama Consulting, High Performance PV, IEC, Munich RE – HSB, NREL, PCG Solar, Sandia, SunSpec, TUV, Wells Fargo
~50 SolarPlaza O&M participants contributed to the gaps analysis on March 26
Gaps Analysis for O&M Activities

A Universe i. What standards and best practices have an O&M component
ii. Isolating Standards – SNL working group reviews
iii. Working Group Coordination Meeting -
iii. Working Group Coordination Meeting – best practices and other standards identified
Gaps identified
(orange boxes)
v. Document this process: consolidate gaps, map efforts to
Design •Look to reliability standards of other more mature industries, such as fossil-fuel generators •Consider measurability in specification of equipment during design (built-in current transducers)
Risk Mitigation (Financing) •Specification Standard: feeds into design, provide all details for all environment •Reduce Complexity of O&M Programs
Construction •Protocol to test incoming equipment to a site •Wire management, conduit standards, conductor standards, layout standards
Commissioning •Need to bridge the gap between IEC standards regarding commissioning and the NEC. Inspecting for code compliance is an essential commissioning step and failure to comply with codes is often a source of reliability and safety issues
O&M •Need to Certification of O&M providers: O&M Curriculum, training, education, experience, and job description
Transaction Process •Need to Disclosure requirements – or “client’s bill of rights” that would require those responsible (EPC’s, O&M service providers, manufacturers) to disclose common failures and to disclose the cause and consequences of events

PV System Delivery Elements Positively impacted by effective standards
All PV System Delivery Elements Must Be Considered
