Solar Repair & Support in Rotherham
Rotherham has one of the highest concentrations of social-housing solar retrofits in South Yorkshire. Most were installed through council energy efficiency programmes a decade ago — and now the inverters are failing in waves. We're fifteen minutes away and we carry the parts these systems need.
Tell us what's happening with your system. We'll confirm whether it needs a remote diagnostic or an on-site visit, and give you a clear price before any work starts. Rotherham is about 15 minutes from our base — one of our fastest response areas.

Solar in Rotherham — what we see on the ground
Rotherham was one of the biggest beneficiaries of government-backed solar retrofit programmes in South Yorkshire. Between 2012 and 2015, thousands of social-housing properties — predominantly 1960s to 1980s semis and terraces across estates in Rawmarsh, Kimberworth, Brinsworth, and East Herringthorpe — had systems installed through council energy efficiency schemes, most commonly by Mark Group. Those systems are now 8 to 12 years old, and the inverters are entering the failure zone.
Rotherham's solar landscape is dominated by council-scheme installs from the Feed-in Tariff era. These are typically 2–3.5kW systems on 1960s–1980s semis with polycrystalline panels and budget string inverters. The panels are still going strong — 25+ year lifespan — but the inverters were always the weak link, and thousands are now reaching end of life simultaneously.
String inverters have a typical lifespan of 10–15 years. Rotherham's systems were mostly installed in 2012–2014 — meaning the borough is right in the middle of its first major inverter replacement cycle. We're replacing Solis, Growatt, and Fronius units across the borough every week. Modern replacements are more efficient and often come with 10–12 year warranties.
Some Rotherham systems installed through council schemes were never properly registered for Feed-in Tariff export payments, or the generation meter was never read after the installer folded. If you've been on deemed export for years or your FiT paperwork is missing, we can help sort it out as part of a system health check.
Most Rotherham solar properties are 1960s–1980s semis and end-terraces with pitched roofs facing south or south-west. System sizes cluster around 2–3.5kW. Newer private installs in Wickersley, Bramley, and Whiston run larger — 4–6kW with GivEnergy or SolarEdge hybrid inverters and batteries. We work with all of them.
What we do in Rotherham
Rotherham sits right next to our Barnsley base, so response times are short. Most systems here are FiT-era string inverter setups. We check monitoring data and fault logs remotely before every visit — arriving with parts and a plan. No call-out fees. Pricing always confirmed first.

Remote diagnostic →What goes wrong with solar systems in Rotherham
Rotherham's solar stock is heavily weighted towards council-scheme installs from the early 2010s. The faults we see reflect that — ageing hardware on a predictable timeline. Most start with a remote diagnostic.
This is overwhelmingly the most common fault in Rotherham. Thousands of Solis, Growatt, and Fronius string inverters installed between 2012 and 2014 are hitting the 10–12 year mark and failing. Symptoms: no generation, blank display, red fault light, or persistent error codes. At this age, replacement is the right move — we carry stock of the most common units and can usually fit within a few days of diagnosis. Inverter replacement →
A surprisingly common issue on Rotherham council-scheme installs. Some systems were never properly registered for Feed-in Tariff export payments, or the generation meter hasn't been read since the installer folded. You may be owed money, or you could switch to the Smart Export Guarantee for ongoing income. We check all of this during a system health visit and help you get the paperwork straight. Annual maintenance →
Many older Rotherham systems either never had monitoring set up or lost their WiFi connection years ago. The system may still be generating perfectly well — you just can't see it. We reconnect monitoring remotely in most cases and set up app-based tracking so you can see generation, export, and self-consumption in real time. Monitoring offline guide →
Newer private installs in Wickersley, Bramley, and Whiston are increasingly using GivEnergy hybrid inverters and batteries. When the battery stops charging overnight from cheap-rate electricity or won't discharge during the day, the cause is almost always settings, firmware, or tariff configuration — not hardware. We fix this remotely in most cases. GivEnergy support →
Your Rotherham installer has gone — your system hasn't
Rotherham was hit hard by installer failures. Mark Group — responsible for the majority of social housing solar retrofits here — went into administration in 2015. More recently, two other South Yorkshire installers have folded. If your installer has gone, we handle the full recovery: monitoring transfer, documentation rebuild, warranty claims, and ongoing support.
Administration 2015. Installed the vast majority of Rotherham's social housing solar systems through council energy efficiency schemes. Solis and Fronius inverters now 10–12 years old.

GivEnergy battery systems in Rotherham
While older Rotherham systems are predominantly panel-only installs, the newer private market — Wickersley, Bramley, Whiston, Dalton — is increasingly GivEnergy. Whether you've had a battery retrofitted to an existing array or it came with a full new install, we diagnose and fix every GivEnergy fault. Battery not charging, portal offline, system importing when it shouldn't be — we see it all.

Just bought a house in Rotherham with solar panels?
Rotherham has thousands of homes with solar from the council retrofit era, and many change hands without any documentation. If you've moved in and there are panels on the roof but no paperwork, no monitoring, and no idea whether the system even works — that's exactly what we sort out. We visit, identify the full system, set up monitoring in your name, check warranty status, and give you a clear written report.
Solar repair in Rotherham — common questions
Rotherham is about 15 minutes from our base in South Yorkshire, so it's one of the fastest areas in our coverage for on-site response. Urgent faults — inverter failure, no generation, battery down — we can usually attend next working day. Planned work like inverter replacements and annual maintenance is typically within a few days. A remote diagnostic at £75 can identify most faults same-day if you need answers before we visit.
Yes. A large number of solar systems in Rotherham were installed through local authority energy efficiency programmes, most commonly by Mark Group before they went into administration in 2015. These systems are now 10 to 12 years old, and the inverters are reaching end of life. We regularly service and replace hardware on council-scheme installs. The manufacturer warranties on your panels and inverter are separate from the installer, so those may still apply even though the original company has gone. Mark Group guide →
Inverter replacement starts £795, which covers the new unit, removal of the old one, installation, configuration, and commissioning. The exact cost depends on brand, model, and system size. Many Rotherham systems from the social housing retrofit era use Solis or Growatt inverters — we carry stock of the most common replacements. A remote diagnostic at £75 confirms exactly what's needed before we quote — no guesswork. Inverter replacement service →
Yes. We cover the whole Rotherham borough including Rawmarsh, Maltby, Wickersley, Bramley, Swinton, Wath upon Dearne, Kilnhurst, Thrybergh, Kimberworth, Thurcroft, Brinsworth, and Catcliffe. All are within a short drive of our base, so response times and pricing are the same as central Rotherham.
