Technician maintaining a solar array

Operations & maintenance

Keeping systems producing what the model promised

A solar asset earns its return over 20 years, not on the day it is switched on. Our O&M work compares actual production against the design model and fixes the gap.

Performance monitoring

Production is tracked against the modelled P50 baseline so underperformance is caught early rather than at year-end.

  • Actual vs modelled yield
  • String-level anomaly checks
  • Alarm review and escalation

Preventive maintenance

Scheduled inspections covering electrical connections, mounting, protection devices and enclosures.

  • Torque and connection checks
  • Thermal inspection
  • Protection device testing

Cleaning programmes

Module cleaning frequency set by site soiling conditions, not a generic calendar.

  • Soiling assessment
  • Site-specific cleaning intervals
  • Water-efficient methods

Inverter & battery servicing

Firmware, cooling, capacity and state-of-health checks in line with manufacturer requirements and warranty terms.

  • Firmware and settings review
  • Battery state of health
  • Warranty-compliant servicing

Fault response

Diagnosis and corrective work on production faults, tripping, communication loss and grid interface issues.

  • Remote diagnosis first
  • On-site corrective work
  • Spares and replacement coordination

Reporting

Periodic reports covering production, availability, interventions and recommendations for the asset owner.

  • Production and availability
  • Intervention log
  • Annual performance review

Response times, inclusions and site visit frequency are set per maintenance agreement and depend on site location and system size.

Set up a maintenance agreement

Tell us the system size, location and installation year and we will propose a maintenance scope suited to the asset.
