Solar Panel Repair in Wakefield
Wakefield's solar stock is split between two eras. Older 2–4kW arrays on 1960s–80s coalfield semis — installed through government schemes by contractors who have since folded — and newer GivEnergy battery retrofits on detached properties across Ossett, Horbury, and the Five Towns. Both need different repair approaches, and we handle both on-site.
Describe the fault — error codes, display messages, generation figures. We review your monitoring data before the visit so the engineer arrives prepared.

Wakefield's housing stock drives its fault profile. Coalfield-era semis in Castleford, Pontefract, and Normanton tend to have compact roof arrays with ageing string inverters. Larger detached properties in Ossett and Horbury are more likely to run hybrid inverters with battery storage. Here's what breaks down and why.
The single most common repair in the Wakefield district. Mark Group installed thousands of 2–4kW systems on suburban semis between 2012 and 2015, almost all using Fronius IG or Solis Mini string inverters. At 10–14 years old, these units are failing — blank displays, recurring fault codes, or simply producing nothing. The panels are fine; the inverter has worn out. Replacement from £795 including commissioning.
GivEnergy is the dominant battery brand across the Wakefield district. Common complaints: battery draining to grid overnight, not charging from solar during the day, or charge schedules not matching tariff rates. Usually a configuration issue — reversed CT clamp, eco mode disabled, or a firmware update that reset schedules. We diagnose and resolve most of these remotely at £75.
Wakefield's coalfield housing stock dates mostly from the 1960s–80s, and solar installations on these properties often involved routing cables through loft spaces with poor ventilation. After a decade, DC isolators degrade, MC4 connectors corrode, and junction boxes develop water ingress. These are safety-critical faults that need on-site inspection and replacement.
Homeowners notice their system producing less than it used to but there's no error code or flashing light. In Wakefield this is often caused by tree growth creating new shading on south-facing roofs, a failed bypass diode reducing string output, or an MPPT tracker degrading inside the inverter. We compare actual yield against expected output for the array size and orientation to identify the cause.
Use the fault finder to describe your symptoms, or start with a £75 remote diagnostic.

How a Wakefield repair works — from enquiry to fix
We follow the same process for every repair. No wasted trips, no surprise invoices, and the engineer arrives already knowing what's likely wrong.
Tell us what you're seeing — error codes, flashing lights, no generation, battery not charging, monitoring offline. Include photos of the display if you can. The more detail, the faster the diagnosis.
We access your monitoring portal, review generation history, analyse charge and discharge patterns, and check firmware versions. This identifies the fault in most cases and tells us exactly what parts or tools the engineer needs to bring. If the fault is configuration-only, we fix it remotely and you don't need a visit.
If an on-site visit is needed, we confirm the cost in writing before booking. The quote covers labour, parts, and commissioning. The £75 diagnostic fee is credited against the repair cost. You approve the quote before we schedule the visit.
The engineer arrives with the right parts. Wakefield is 25 minutes from our Leeds base, so urgent faults get a one to two working day response. The repair is completed, the system is tested, monitoring is verified live, and you receive a written report covering what was done and what to watch for.

Mark Group installed your system — now they're gone
Mark Group was the dominant solar installer in the Wakefield district, fitting thousands of 2–4kW systems through government energy efficiency programmes before going into administration in 2015. A decade later, these systems are reaching the age where inverters fail, DC isolators degrade, and monitoring connections drop. We pick up where they left off — diagnosis, repair, inverter replacement, and ongoing maintenance on every system they installed.
Every solar and battery brand — diagnosed and repaired
Wakefield has one of the widest brand mixes in West Yorkshire. Government scheme installs used Fronius and Solis. Private installs added SolarEdge, Growatt, and Sunsynk. Battery retrofits are overwhelmingly GivEnergy. We carry diagnostic equipment for all of them.

Every visit starts with a pre-arrival review of your monitoring data and fault history. On site, we test the inverter, check DC string voltages, inspect wiring and isolators, and verify battery communication where applicable. Once we identify the fault, we confirm the repair cost in writing before starting any work. Most visits are completed the same day.
Yes. Fronius IG and Solis Mini string inverters are the most common replacements we carry out in the Wakefield district. These were installed by Mark Group and other government scheme contractors between 2012 and 2015, and most have now exceeded their expected lifespan. We supply, install, and commission the replacement unit — typically a GivEnergy or Solis hybrid — from £795 including labour. Inverter replacement details →
