Premium Solar & Battery Storage
We Fix What Others Installed
We started as a repair company — fixing solar systems installed by companies that have since disappeared, installers who cut corners, and builders who subcontracted the solar to the cheapest bidder. Over more than a decade, we've seen every failure mode: corroded connectors, failed bypass diodes, cracked cells hidden under intact glass, inverters dying from overheating because someone installed them in direct sunlight, and DC isolators that are genuinely dangerous. We carry thermal cameras, I-V curve tracers, and replacement parts on every vehicle. Most repairs are completed on the first visit. And if we can't fix it, you don't pay for the diagnostic visit.

Why Choose Us for Solar Repair
Fast Diagnosis
We use thermal imaging, I-V curve tracing, and electroluminescence testing to pinpoint exactly which panel, string, or component is causing underperformance — without guesswork.
DC Isolator Safety
Faulty DC isolators are a fire risk on older solar systems. We proactively replace isolators over 10 years old, and carry out emergency replacements when faults are identified.
Panel Replacement
Individual panel replacement without disturbing the rest of your system. We match voltage and current specs carefully — if your original model is discontinued, we source the closest compatible replacement.
Inverter Repair & Replacement
From interpreting error codes and resetting tripped systems through to full inverter replacement, we cover every inverter brand and model installed in the UK.
FiT Orphan Specialists
Your original installer may have gone bust, but your warranty claim hasn't. We help FiT-era system owners navigate manufacturer warranty claims for components that are still covered.
No Fix, No Fee
If we can't diagnose a fault or improve system performance, you don't pay for the diagnostic visit. We're confident in our technical ability — and our pricing reflects that.
How It Works
Remote Diagnosis
We review your monitoring data remotely to identify underperforming strings, sudden output drops, or persistent error codes before we arrive — saving time on site.
On-Site Diagnostic
Using thermal imaging, multimeter testing, and I-V curve tracing, we identify the exact fault — panel, string, inverter, isolator, or wiring — with evidence.
Repair or Replace
We carry common spare parts on every vehicle. Most panel faults, connector issues, and minor electrical faults are resolved on the first visit.
Verification
After repair, we verify the system is performing correctly against expected output before closing the job. You receive a written report with before and after data.
Frequently Asked Questions
Not necessarily — the panels may still be fine. A string inverter failure does stop the whole system from generating, but the panels themselves are often undamaged. We'll diagnose whether the inverter needs repair or replacement, and whether any panels were affected.
