O&M support for existing solar sites.

A solar farm or rooftop array is only as good as the last time someone with a multimeter actually walked it. We provide planned servicing, drone-based string inspection, fault-finding and component replacement on existing utility-scale sites.

What's in scope

Real maintenance, not just a yearly visual.

Planned preventative maintenance

Scheduled site visits, panel cleaning where needed, mounting and clamp checks, and DC/AC system tests.

Drone string inspection

Thermal imaging across whole arrays — fastest way to find dead strings, hot spots and failed bypass diodes.

Inverter replacement

We carry common spares and can replace failed inverters quickly to minimise lost generation revenue.

Fault response

Defined SLA response times for monitored faults — we'll agree the level that matches the value of your site.

Performance reporting

Monthly or quarterly performance reports against expected yield, with explanations for any underperformance.

End-of-warranty inspections

We assess the array against original spec ahead of warranty expiry so any manufacturer claims can be lodged in time.
