Solar Panel Repair in Yorkshire
Yorkshire has tens of thousands of ageing solar systems — many installed during the Feed-in Tariff era by companies that have since gone bust. Panels not generating, inverter fault codes, batteries not charging, monitoring offline — we diagnose and fix all of it. Based in Leeds, covering the full region on-site.
Tell us what's happening — fault codes, display messages, generation figures. We'll start with a remote diagnostic and confirm whether an on-site visit is needed.

Faults on Yorkshire solar systems are accelerating — and most homeowners have nowhere to turn. The region's FiT-era installation boom left tens of thousands of residential systems with no aftercare when their installers folded. Now those systems are 10–15 years old, and the components that wear first — inverters, DC isolators, MC4 connectors, monitoring gateways — are failing at the same time. The panels themselves are fine. Everything around them needs attention.

We diagnose and repair every major solar and battery brand
Manufacturer helplines can run remote diagnostics, but they can't send someone to your roof. Local electricians can do wiring, but they rarely have solar-specific fault experience. That gap — between remote diagnosis and on-site solar repair — is what we fill. We're independent, based in Leeds, and we carry out solar and battery repairs across Yorkshire every day.
Common solar faults we repair across Yorkshire
These are the fault categories we see most often on Yorkshire systems. Each requires a different diagnostic path — which is why we always diagnose before quoting.
Fault codes, blank screens, red lights, failed start-up, arc fault detection, earth leakage alarms. The most common fault category on 10+ year old Yorkshire systems. Repair or replacement — we confirm which before quoting.
Battery not charging, BMS errors, CAN communication failures, firmware corruption. Common on GivEnergy, Sunsynk, and Growatt systems across the region. Often fixable remotely — hardware replacement only when confirmed.
System underperforming, individual panels not contributing, string imbalance. Caused by panel-level faults, bypass diode failure, shading changes, or degraded connections. We use monitoring data and thermal imaging to locate the fault.
Corroded MC4 connectors, damaged DC isolators, incorrect CT clamp installation, missing earth bonds. Common on systems installed without proper commissioning — especially social housing schemes across South Yorkshire.
Emergency power supply not activating during grid outages, island mode misconfigured, neutral-earth bond missing. We test and verify EPS function on-site so you know it will work when you need it.
Portal offline, WiFi dongle failed, monitoring data gaps. Often the first sign something else is wrong. We restore connectivity, recover historical data where possible, and set up alerts so you're notified of future faults.

Your installer folded — and now something's wrong
When your installer folds, you lose more than aftercare — you lose the engineer who understood your system. Error codes mean nothing without someone who knows your specific inverter model, wiring configuration, and monitoring setup. We diagnose and repair systems left behind by Mark Group, Solarplicity, Snug Energy, and All Seasons Energy every week. No guesswork — we start with a full diagnostic before recommending any parts or work.
Solar repair in Yorkshire — common questions
Most on-site repairs are £249–£599 depending on the fault and parts needed. Configuration faults — CT clamp errors, export limit problems, charge schedule issues — are usually resolved remotely at £75. If the inverter needs replacing rather than repairing, that's typically £795–£1,200. We always confirm the full cost in writing before starting work. Full pricing breakdown →

Yes — this is one of the most common reasons people contact us in Yorkshire. Mark Group, Solarplicity, Snug Energy, and All Seasons Energy all installed thousands of systems across the region before folding. We repair and maintain all of their systems. The manufacturer warranties on your inverter and panels are separate from the installer and may still be valid. Full installer gone bust guide →
