I wholeheartedly recommend. Many thanks to Ron. Amazing. Everything is fixed. And I feel safer now that I know where to come for support if anything else happens. I contacted STS for help via their extremely useful website which told me exactly what I had done wrong to require support. My GivEnergy battery had been dead for a while and an attempted firmware update had stopped the inverter. The support was prompt and very professional and over and above what I expected. I was helped every step of the way with clear instructions and e-mail support for questions. The issue was resolved within 24 hours and a technical report produces from log data to share with Octopus to try to get to the bottom of how the original issue occurred. Despite Ron saying that mine was a familiar issue with Octopus Intelligent Flux, this to me was service over and above expectations.

Ron was really helpful. He remotely adjusted my battery settings on the same day I contacted him, and at a reasonable price. Great service.
When my GivEnergy battery started playing up it became basically useless and several companies I called said they couldn’t help. Solar Tech Support really knew their stuff, communicated very well and resolved the problem quickly. Without them I’d have had to buy a replacement battery.
Ron was very knowledgeable and patient as we worked through the cause of Givenergy Hybrid Inverter suddenly failing (with 0W grid). He was able to quickly identify the probable cause, and point me in the right direction to identify the ‘burnt out’ AC isolator switch & piece of cable, which I was able to find a local electrician to replace. The best £95 I have spent. Thanks Ron.
Contacted Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone
Outstanding support, very detailed knowledge of the system and clarity on what was needed to fix it, no hesitation in recommending them to all.
Solar in Barnsley — what we see on the ground
Barnsley has one of the highest densities of residential solar installations in South Yorkshire. The majority were installed between 2012 and 2015, during the peak Feed-in Tariff era, on ex-council terraces, semi-detached homes, and 1960s–1970s housing estates. Many were fitted through government energy efficiency schemes — particularly by Mark Group, which installed thousands of systems across the borough before going into administration in 2015.
Most Barnsley systems are now 10–13 years old. The panels themselves are fine — they last 25+ years. But string inverters have a typical lifespan of 10–15 years, and we're seeing a steady increase in inverter failures on these older 2–4kW systems. If your inverter has stopped working, it's almost certainly due for replacement rather than repair.
GivEnergy is the most popular battery brand we see on newer installations in Barnsley. Homeowners adding batteries to existing solar systems almost always choose GivEnergy — attracted by the price point, the app, and Octopus Go/Agile tariff integration. We handle all GivEnergy diagnostics, configuration, and repairs.
Older Barnsley systems typically have Fronius, Solis, or Growatt string inverters with polycrystalline panels. Newer installs use GivEnergy, SolarEdge, or Sunsynk hybrid inverters with monocrystalline panels. We work with all of these — 19+ brands, all diagnosed the same way.
Barnsley's housing is predominantly terraces and semis with south or south-east facing roofs — good for solar yield. Typical system sizes range from 2kW on smaller terraces to 4kW on semis. Newer installs on larger properties in Dodworth, Penistone, and the rural fringe run 5–6kW with batteries.

What we do in Barnsley
Barnsley is one of our core coverage areas. Every repair visit starts with a remote diagnostic — we check monitoring data and fault logs before we arrive, so we know what's wrong and bring the right parts first time. No call-out fees, no surprises.
Fault diagnosis and on-site repair — inverter failures, generation drops, grid faults, battery problems. From £295.
Fault diagnosis →Old inverter out, new one in. Configured, commissioned, and tested. All brands — Fronius, Solis, GivEnergy, SolarEdge, and more. From £995.
Inverter replacement →Add emergency backup to your existing battery — keep lights, broadband, and fridges running during a power cut. We wire a dedicated EPS circuit into your consumer unit.
EPS installation →Full annual health check — generation benchmarking against local Barnsley averages, inverter diagnostics, wiring and isolator inspection, firmware updates. Written report. From £195.
Annual maintenance →Inherited solar panels in Barnsley? Many local systems are FiT-era with no documentation. We visit, identify every component, configure monitoring, check your FiT status, and hand you a written report. From £295.
On-site walk-through →Same-day remote analysis — we pull your monitoring data, check fault logs, review firmware, and diagnose the issue. Written report with clear next steps. Free — £125 only if we fix it remotely.
Remote diagnostic →What goes wrong with solar systems in Barnsley
After years of working on Barnsley systems, these are the faults we see most often. Most start with a remote diagnostic — and many can be resolved without an on-site visit at all.
The single most common fault in Barnsley. Fronius, Solis, and Growatt inverters from 2012–2015 FiT installs are reaching end of life. Symptoms: no generation, blank display, or persistent error codes. The fix is a replacement, not a repair — inverters at this age are past the point of economic repair. We carry stock of the most common replacement units. Inverter replacement →
Very common on newer GivEnergy installs in Barnsley. The battery should charge from the grid overnight on cheap-rate electricity (Octopus Go/Agile) and discharge during the day. When it stops, the cause is almost always settings or firmware — not hardware. We fix settings remotely in most cases. If it needs a firmware update, we do it manually, to our own written procedures: on a callout, or by talking you or your electrician through it remotely. GivEnergy support →
Monitoring apps showing "offline" or "no data" don't necessarily mean the system has stopped generating. In most cases, the WiFi dongle has lost its connection to the router. The system is often working fine — you just can't see it. Our guide has the general WiFi checks to try first. If it still won't connect, we set it up on site, from £195: we connect it to your WiFi, set up your router, including a separate 2.4 GHz network if it needs one, and check it's reporting. Monitoring offline guide →
Older Barnsley systems that were generating well for years can gradually drop in output. Common causes: partial shading from tree growth, soiled panels, degraded DC isolator, or a failing MPPT tracker in the inverter. A remote diagnostic comparing current output to expected yield usually identifies the cause. System underperforming guide →
Your Barnsley installer has gone — your system hasn't
Several installers who worked extensively in Barnsley have since ceased trading. If your installer has gone into liquidation or disappeared, the system still works — it just needs independent support. We handle the full recovery: monitoring transfer (not GivEnergy), documentation rebuild, warranty claims, and fault diagnosis.

GivEnergy is the most common battery brand in Barnsley
Whether you've had a GivEnergy battery retrofitted to an existing solar 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, inverter showing error codes — we see it all and resolve most settings issues remotely. GivEnergy Ltd entered administration on 9 April 2026, so its manufacturer warranty is no longer being honoured. Cover may still sit with an installer workmanship guarantee, an insurance-backed guarantee, a Section 75 credit card claim, or the MCS Consumer Code. We work out which applies to your install, and we supply and install replacement GivEnergy hardware at fixed prices.

Just bought a house in Barnsley with solar panels?
Barnsley has thousands of FiT-era solar homes — and they change hands regularly. Most were installed by Mark Group or through council schemes, so the paperwork often went missing when the installer folded. If you've moved in and there are panels on the roof but no manuals, no app, and no idea whether it's generating — that's exactly what our on-site walk-through is for. We identify every component, reconnect monitoring, chase down any missing certificates, and hand you a written report.
