A clause-by-clause checklist for reviewing a solar O&M contract: scope, module cleaning, spare-parts model, performance-ratio and availability guarantees with their liquidated damages, reporting, response times and termination — with the industry benchmarks to test each clause against. It reflects SgurrEnergy’s independent O&M contract-review methodology.
How to use this checklist
Work through each section against the O&M contract and flag departures from the benchmarks. Benchmarks are published industry norms (SolarPower Europe O&M Best Practice Guidelines and standard market practice) and should be adapted to the asset and jurisdiction. This is a technical-review aid, not legal advice.
Contract basics
- Title, plant capacity, execution vs service-commencement date confirmed
- Tenure and extension options defined
Scope of services
- Plant, switchyard and transmission-line coverage delineated
- Employer vs contractor obligations clear
- Preventive and corrective maintenance both in scope
Scheduled and unscheduled maintenance
- Scheduled task list and frequencies specified (Annual Maintenance Plan)
- A defined process for unscheduled events: response time, severity categorisation, owner authorisation for out-of-scope repairs
Module cleaning
- Manual vs robotic method specified
- Water-supply responsibility defined
- Cleaning is warranty- and IEC-compliant and driven by soiling measurement
- For robotic systems, AMC and downtime addressed
Price, escalation and payments
- Fixed vs variable fee, and per-MW sanity check
- Year-on-year escalation mechanism
- Payment cadence and any performance incentives
Spare parts and consumables
- Spares model identified: owner-direct, contractor-managed, or hybrid
- Responsibilities, procurement route and lead-time management defined
- Module spares (~0.2% of module count) and spare-parts warranty (~12 months) confirmed
Performance-ratio guarantee and PR-LD
- PR definition, calculation methodology and allowable degradation defined
- Guaranteed PR is realistic versus actual/expected performance
- PR-linked liquidated damages defined (note the market shift from PR guarantees toward availability + response-time mechanisms for independent operators)
Availability guarantee and availability-LD
- Availability definition and calculation methodology defined
- Events outside the contractor’s control (grid, force majeure) excluded — but not spare-parts delays
- Guaranteed level benchmarked against industry norms (~98–99%)
- Availability-linked LDs defined
Liability, reporting and termination
- LD cap / limit of liability reasonable (market range ~5–20% of contract value, or ~100% of the annual O&M fee under the current independent-operator norm)
- Performance, maintenance and incident reporting specified
- Response times defined by issue severity
- Bank guarantees, termination rights and force majeure adequate
