O&M (Operations & Maintenance) is the structured service that keeps your PV, PV+BESS, or hybrid system operating safely and delivering the expected performance over its lifecycle. It covers monitoring, planned maintenance, fault response, reporting, and warranty coordination.
Solar assets are performance infrastructure. Without disciplined O&M, systems typically experience:
• Avoidable downtime and delayed fault resolution
• Rreduced energy yield due to soiling and undetected underperformance
• Shortened component life (especially batteries and power electronics)
• Warranty disputes due to missing evidence or poor maintenance records
Bankability and lender acceptance also require an O&M framework with auditable reporting.
URPC O&M typically includes:
• Monitoring and alarm management (24/7 where applicable)
• Preventive maintenance (planned inspections and tests)
• Corrective maintenance (fault diagnosis and repair)
• Routine PV cleaning to a defined cadence
• Spares strategy (critical spares list + lead times)
• Performance reporting (monthly KPI pack)
• Warranty management and OEM interface
• HSE controls and site compliance for maintenance works
Where a system is telemetry-enabled, URPC provides centralised monitoring and alarm management through our operations model. Monitoring scope is defined per project and may include PV output, inverter events, battery SoC/SoH, load profile, power quality indicators, and alarms.
Default cadence (adjusted to site soiling conditions):
• Dry season: every 4 weeks
• Wet season: every 8 weeks
URPC may adjust this cadence based on measured performance variance and site conditions.
An SLA (Service Level Agreement) defines the response and restoration commitments for incidents, including:
• Incident severity levels
• Remote response targets
• Dispatch targets
• Restoration targets (or workaround targets where spares lead times apply)
• Exclusions (e.g., grid outages, force majeure, client-caused issues)
The SLA is agreed contractually and is designed to be enforceable and auditable.
A common structure is:
• S1 Critical: immediate operational impact (critical loads affected)
• S2 Major: significant performance reduction but partial operation remains
• S3 Minor: non-critical fault or limited impact
• S4 Advisory: optimisation or non-urgent issue
Exact definitions and targets are set per project.
SLA performance depends on:
• Safe site access and security
• Client cooperation (permits-to-work where required)
• Spare parts availability and OEM lead times
• Communication uptime (telemetry/connectivity)
• Whether the issue is within URPC scope or utility-side (grid)
URPC documents exclusions and dependencies explicitly to avoid ambiguity.
For uptime-critical sites, URPC recommends a critical spares strategy, including:
• Agreed spare parts list and minimum stock
• Lead time plan for key components
• Substitution rules aligned to OEM guidance
Spares can be client-owned and URPC-managed, or supplied under a portfolio model, depending on the contract.
URPC manages warranty administration by:
• Maintaining a warranty register
• Gathering evidence (logs, measurements, photos, incident reports)
• Coordinating claims and replacements with OEMs
Warranty outcomes depend on compliance with OEM operating conditions and maintenance records.
URPC typically provides a monthly performance pack including:
• Availability and downtime classification
• Energy yield and performance ratio (PR) trends
• Incident summary with root-cause analysis and corrective actions
• Battery SoH/SoC trends (where applicable)
• Cleaning logs and maintenance records
• Spares and warranty status
For multi-site clients, portfolio reporting can be consolidated.
Common KPIs include:
• Availability
• Response time and MTTR (mean time to repair)
• Performance ratio (PR)
• Battery SoH and cycling metrics
• Diesel displacement (where applicable)
• Preventive maintenance compliance (% completed on schedule)
Typical exclusions (defined in contract) may include:
• Utility-side outages and upstream grid faults
• Vandalism/theft/fire unless covered under insurance scope or addendum
• Client-side electrical alterations or unsafe conditions
• Damage due to unauthorised tampering or misuse
URPC makes exclusions explicit in the SLA to maintain operational clarity.
In most financed structures, yes. Lenders typically require O&M for the full financing tenor to protect availability and safeguard cashflows. The O&M agreement is therefore aligned to the repayment period.
O&M can be structured as:
• Fixed monthly/annual fee
• Availability-based service (incentives/credits)
• Energy-based service (per kWh managed)
• Portfolio O&M for multi-site clients
Pricing depends on system size, SLA level, site conditions, and monitoring scope. As a planning reference, O&M is often structured around an annual percentage of system cost, billed monthly or annually, subject to the agreed scope and SLA.
Remedies are defined contractually and may include service credits, escalation triggers, and corrective action plans, subject to exclusions and dependencies. URPC’s approach is to maintain auditable ticketing and evidence packs to support fair performance governance.
Yes. SLA adjustments are managed through a formal change control process. Changes to targets or scope may affect O&M fees, spares requirements, and operational resourcing.
URPC will confirm:
• System documentation status (as-built pack, serials, protections)
• Monitoring readiness and access permissions
• Baseline performance and warranty status
• Agreed SLA and reporting format
Then O&M mobilisation begins with a site onboarding visit and monitoring activation.
O&M scope, SLAs, and KPIs vary by system class, site conditions, and contractual model. Any service targets are subject to documented exclusions, safe site access, spare-part lead times, and compliance with agreed operating conditions. Binding obligations apply only as set out in executed agreements and schedules.
