Performance & fault finding
Monitoring, site inspections, thermal imaging and electrical testing to locate the problem before prescribing work.
HIT ENERGY SERVICES / UTILITY SOLAR
Keep the asset generating.
With over 15 years’ experience on utility solar sites, HIT brings monitoring, practical engineering and documented delivery to everything from cable theft recovery to 33 kV transformer repowering.

More than a maintenance visit
The work behind reliable generation.
When a site trips, suffers damage or starts losing output, we find the cause and deliver the work.
HIT has maintained and monitored utility solar sites for over 15 years, since the early UK rollout. Our team moves from string-level data and field inspection to a defined scope, repairs, testing and clear completion records.
What we do
Built for the difficult jobs.
Support for owners, asset managers and delivery partners responsible for keeping large PV sites safe and productive.
Damage & cable theft
Make affected circuits safe, replace damaged cabling and connectors, test the repaired strings and return generation in stages.
DC infrastructure
String rewiring, buried cable faults, combiner boxes, fuse carriers and protection defects across extensive arrays.
Electrical projects
Defined work packages, coordinated equipment changes, 33 kV transformer projects and electrical supply replacement.
Repowering
Evidence-led upgrades to ageing or underperforming equipment, retaining useful infrastructure where it remains suitable.
Records & handover
Photographs, test results, remedial records and commissioning evidence showing what changed and what returned to service.
Insurance related works
Evidence when damage has stopped generation.
After a break-in, fire, weather event or equipment failure, the immediate priority is to understand the affected circuits and make the site safe. The next is a practical route back to production.
- Inspect and document damage
- Scope and quote the remedial work
- Coordinate repairs and replacement components
- Test, recommission and report on completion
Technical reports can support an owner’s insurance claim. Coverage and settlement decisions remain with the insurer.
Project evidence / 33 kV
From early warning to generation restored.
On a long monitored utility site, HIT’s inspections identified developing problems in 33 kV transformers and protection equipment. The work became a major replacement project. Client and site details remain private.
TRANSFORMER EQUIPMENT PROJECTA real HIT project
33 kV transformer & protection repowering
Monitoring and maintenance checks, including oil checks and thermal imaging, identified faults and potential safety and generation risks.
- Identify and report the transformer and protection issues
- Procure replacement 33 kV transformers
- Decommission the old units
- Replace 33 kV and LV supplies, with bespoke components for the new housings
- Reinstate generation to the grid
How HIT works
One accountable path from fault to handover.
01 / UNDERSTAND
Review the evidence
Alarms, historical performance, site records and inspection findings.
02 / SCOPE
Plan the work
Define the affected equipment, isolation, access, programme and parts.
03 / DELIVER
Repair & test
Carry out the electrical work, verify the circuits and coordinate specialists where needed.
04 / PROVE
Return to service
Recommission, document results and continue watching performance.
