Solar PV Repairs & Inspections Across the UK: Inverter Faults, Micro-Inverter Fixes & Engineer Reports
If your solar PV system has gone quiet (zero generation), dipped in output, or started flashing fault codes, you don’t need guesswork—you need structured fault-finding. A proper repair visit isn't just about swapping a box; it involves electrical testing, inverter diagnostics, and performance benchmarking to avoid paying for the same fix twice.

Why Do Solar PV Systems Fail?
Most solar failures aren't mysterious. They are usually caused by inverter failure, tripped protection devices, or damaged cabling (often from birds). Inverters typically last 8–15 years. If your system isn't generating, don't just keep resetting it—especially if you notice heat or intermittent faults.
- Total Generation Loss: Usually linked to a central string inverter failure.
- Partial Loss: Often caused by failing micro-inverters or shading.
- Physical Damage: Cracked panels or wires damaged by pests.
The "Proper" Solar PV Repair Process
A real solar PV repair is an electrical diagnostic service. We provide structured testing that follows BS 7671 standards to ensure safety and compliance. Our findings are provided in a clear written report, which is essential if you are making an insurance or warranty claim.

Inverter & Micro-Inverter Specialist Support
Whether you have a central string inverter or individual micro-inverters (like Enphase) and optimisers (like SolarEdge), we can diagnose the fault. Monitoring failures can often mimic generation failures, so we test on-site to verify if power is actually being produced.
| String Inverters — Diagnostics and full replacement for central units. |
| Micro-Inverters — Branch testing and individual unit replacement. |
| Insurance Reports — Written evidence suitable for claims and warranties. |
Five-Year Solar PV Health Checks
Solar systems benefit from periodic inspection. A 5-year check catches early inverter wear, detects insulation degradation, and verifies that protective devices are still operating correctly. This is a smart move for system longevity and property sales.

If panels are cracked, storm-damaged, or showing "hotspots," you'll need professional documentation for your insurer. We provide clear photographic evidence and engineer-led reports that confirm what failed and why, helping to move your claim forward quickly.
