Ron came investigate and provide me with a detailed report and standing behind his words for my case His knowledge and understanding are simply exceptional. I can not express how happy I am to have the luck to deal with him
After 7 months of not being able to access/control my system following a change of wi-fi provider, followed by the news that GivEnergy had ceased trading i was left high and dry. I was unable to get any help whatsoever from my installer, tried various electrical tradespeople etc but no-one knew how to help me. Changed the Dongle but then couldnt get this change recognised in the inverter. Found Solar Tech Support while researching yet again online. Ronald has been amazing. Responding very quickly to my emails and very knowledgeable on the system. Managed to give us the information we needed to get the Dongle up and running and created me another account which now works as it should. His help has been invaluable. Thank you so much. Reviews I saw from other people said Solar Tech Support are very good, but i would say they are Outstanding!! Thanks again for all your help- Mick & Sandra
After recently changing my fuse board the ct clamp broke, this meant my inverter was not communicating properly with my GivEnergy system. After several people letting me down, finally got put in touch with Ron. He came out within 24hours & resolved the fault within an hour, no fuse just got on with it. Work was tidy & arrived when he said he would. Ron followed up a few days later to confirm all was still good, great service from all involved.
Excellent knowledgeable company which sorted out my Givenergy issues that no one else could sort! Initial remote diagnosis into what unit(s) where faulty which enabled me to confidently source and buy a replacement at a good price and on so doing Solar Tech then got my system up and running remotely within an hour or two. A1 service!
Ronald at Solar Tech Support was very quick and knowledgeable in helping me restart my GivEnergy solar electric battery. I would highly recommend his services.
Absolutely fantastic experience, after months of being fobbed off with rubbish from the installer Ronald fixed my issues in a few hours, his attention to detail and his tenacity was amazing, not only did he go above and beyond but did not ask for payment i had to ask him how to pay. If you need a solar fix this company is brilliant
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.

Major installers gone bust leaving Yorkshire systems unsupported
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.
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, BMS 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. If it's just the WiFi, we can set it up on site, from £195.

CT clamp errors, export limits, charge schedules, firmware issues. Free diagnosis, charged only if we fix it remotely.
Typically up to £495. Component replacement, wiring faults, battery issues, connector repair. Written quote before work starts.

We're based in Leeds and cover the whole region. Core areas get next-day availability for urgent faults. The full region within a week.
We also cover extended areas including Mansfield, Derby, Nottingham, Manchester, Darlington, and Middlesbrough. Remote diagnostics available nationwide. Full coverage map →
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.
Tell us what's happening — fault codes, display messages, generation figures, how long it's been like this. We'll start with a remote diagnostic and confirm whether a site visit is needed. No call-out fee. Written quote before any work.
Due to unprecedented demand we’re currently only carrying out on-site work in Yorkshire, and replies are taking up to 7 days. Remote diagnostics continue for the whole UK as normal.
