I’ve used Ron a couple of times regarding issues with my Givenergy inverter and batteries after Givenergy went bust. My system stopped working properly so it was a stressful time but Ron resolved the issues and got my system working properly again. He’s really helpful and knowledgeable and I wouldn’t hesitate to recommend him and to use him again if the need arose.

My GivEnergy hybrid inverter + battery system had worked faultlessly for 3 years when it suddenly stopped charging and discharging the battery. On contacting my supplier, who had used a sub-contractor for the installation work, I was provided with an email address at GivEnergy but, as it turned out, this is only for GivEnergy Software who are not able to assist. A Google search led to the Solar Tech Support web site, which contains a wealth of helpful information. I requested a remote solar diagnostic, and after providing Ron access to my inverter, he was able to identify and fix the problem within minutes. I am very impressed by Ron’s expertise and knowledge, which included useful information on the current state of GivEnergy Ltd. I would thoroughly recommend Solar Tech Support.

Ron responded very promptly regarding my GivEnergy battery issue, his knowledgeable diagnosis was spot on and resolved the issue on first attempt. Would recommend to any and all.

When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.

Absolutely wonderful support. I have a GivEnergy system that was installed in 2022, and a firmware update was flagged in the app, so I proceeded to update the software .... and immediately regretted it, as my inverter came up with an error, and was not working at all! With no GivEnergy support available, and my installer saying there was nothing he could do, I googled help, and found Ron. What a stroke of good luck! Submitted an on line enquiry late morning, and received phone call just after 5 pm, and later that evening Ron was able to supply me with old firmware no longer available on the GivEnergy web site. I was then able to update the firmware using a GivEnergy youtube video as reference, and hey presto the system was back up and running. One further slight adjustment by Ron and we are back normal. What a relief. I have no hesitation in recommending Solar Tech Support if you have a problem. Great service! And if you are a GivEnergy system owner, whatever you do, DO NOT UPDATE FIRMWARE!

Local Knowledge
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.
FiT-era installs reaching end of life
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 battery retrofits
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.
Common hardware in this area
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.
Housing stock and system types
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.

Common Problems
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.
1
Ageing string inverter has failed
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 →
2
GivEnergy battery not charging overnight
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 this remotely in most cases. GivEnergy support →
3
Monitoring offline — system status unknown
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. We reconnect monitoring remotely. Monitoring offline guide →
4
System underperforming — lower output than expected
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. Remote diagnostic →
Installer gone bust?
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, documentation rebuild, warranty claims, and fault diagnosis.

New homeowner
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.
System identification — panels, inverter, battery, wiring
Monitoring transfer into your name

Solar repair in Barnsley — common questions
Barnsley is part of our core South Yorkshire coverage. For urgent faults — inverter down, no generation, battery failure — we can usually attend next working day. Scheduled work like inverter replacements and annual maintenance is typically within a few days. A free remote diagnostic can identify most faults same-day if you need answers quickly.
Yes. Mark Group installed thousands of systems across Barnsley through government energy efficiency schemes before going into administration in 2015. Many of these systems used Fronius inverters which are now 10 or more years old and reaching end of life. We regularly replace ageing Fronius units and diagnose faults on Mark Group installs. The manufacturer warranties on panels and inverters are separate from the installer, so those may still apply. Mark Group guide →
Inverter replacement starts £795, which includes the new unit, removal of the old one, installation, configuration, and commissioning. The exact price depends on the brand, model, and system size. We carry stock of the most common replacement inverters for Barnsley-area systems. A free remote diagnostic confirms exactly what's needed before we quote — no guesswork and no surprises.
