I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.
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.
Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them
Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)
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
I've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues
Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.
After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.
Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.
Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.
I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration (their Trustpilot reviews don't lie!). So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.
This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.
I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

Solar in Darlington — steady FiT-era coverage across south Durham
Darlington and south County Durham don't have the sheer density of solar installations you see in West Yorkshire or the East Midlands, but there's a steady spread — mostly FiT-era systems on post-war housing estates and government-scheme installs on social housing. The area also includes the Catterick Garrison corridor, where military and ex-military housing saw a particular concentration of installations. Many of these systems are now 10+ years old, the original installers are gone, and the hardware is reaching the age where faults become common.
Darlington's residential solar is concentrated on the 1950s–1970s housing estates — Cockerton, Haughton, Mowden, Whinfield. These properties have large, unobstructed roof areas ideal for solar, and many took advantage of FiT incentives between 2011 and 2015. Typical installations are 3–4kW arrays with Solis or Growatt string inverters. The panels are still performing well, but the inverters are reaching end of life.
The Catterick Garrison and Richmond area has a concentration of solar installations on military and ex-military housing estates. Some were installed through government energy efficiency programmes, others by private installers under FiT. The high turnover of military tenants means systems go unmonitored for years at a time, minor faults go unreported, and documentation gets lost between occupants.
The rural areas west of Darlington — Barnard Castle, Middleton-in-Teesdale, Stanhope, and the Wear Valley — have scattered larger systems on farmhouses and rural properties. These tend to be 4–6kW installs, often with no monitoring and limited mobile signal making remote diagnostics harder. When they do develop faults, owners often don't notice for months because there's no monitoring in place.
Homeowners across the Darlington area with existing FiT-era systems are increasingly adding battery storage — typically GivEnergy or Sunsynk. Rural properties with higher electricity consumption and off-peak tariff availability benefit most, but the battery needs proper configuration to deliver savings. We see a growing number of retrofit installs where the battery was fitted but never optimised for the household's actual usage pattern.
What we do in Darlington
Darlington is our northern service hub — we cover the town and surrounding areas on a regular schedule. Most systems here are FiT-era installs now needing their first inverter replacement or professional maintenance. Remote diagnostic before every visit. No call-out fees. Pricing in writing.
On-site fault diagnosis — inverter errors, low generation, grid relay faults, panel damage, battery issues. From £245.
Fault diagnosis →Full swap — old inverter removed, new unit fitted, configured, and tested. We cover all mainstream residential brands. £795.
Inverter replacement →County Durham sees more overhead-line outages than average. Adding an EPS circuit means your battery keeps lights, heating controls, and broadband running during cuts.
EPS installation →Annual maintenance visit — system health check, generation analysis, wiring inspection, firmware review, written condition report. From £195.
Annual maintenance →Bought a house with solar in the Darlington area? We survey everything, identify brands and installation date, set up monitoring, and deliver a written system report. From £295.
On-site walk-through →Remote system review — monitoring data, generation history, fault logs, and firmware all checked without a visit. Written diagnostic report usually same-day. £75.
Remote diagnostic →What goes wrong with solar systems in Darlington
The Darlington area's solar install base is predominantly FiT-era systems from 2011–2015, now reaching the age where hardware failures become common. The rural spread and military housing turnover add complications unique to this part of the North East.
The majority of solar systems across Darlington, Newton Aycliffe, and Bishop Auckland were installed between 2011 and 2014 under FiT incentives. They typically run Solis, Growatt, or Fronius string inverters that are now past the 10-year mark. Symptoms: blank display, no generation, intermittent fault codes, tripping the consumer unit. The panels are almost always fine. Replacement with a modern hybrid inverter restores full output and adds battery-ready capability. Inverter replacement →
Rural properties across Teesdale, Weardale, and the Richmond corridor often have larger solar arrays that were never connected to monitoring. Without monitoring, a fault can reduce output by 30–50% and go unnoticed for months or even years — the homeowner just assumes winter generation is always low. We start with a remote diagnostic where possible, or an on-site performance check where mobile signal is too weak for remote access. Remote diagnostic →
Several installers who operated across County Durham and North Yorkshire have since closed — Mark Group, Solarplicity, and a number of smaller regional firms. Homeowners are left with no support route, missing documentation, and locked monitoring accounts. The systems are usually still generating — they just have no one managing them. We handle full recovery: monitoring transfer, documentation rebuild, warranty verification, and ongoing maintenance. Installer gone bust guide →
A growing number of Darlington-area homeowners with existing FiT systems are adding GivEnergy or Sunsynk batteries to take advantage of off-peak tariffs. When the battery isn't delivering the expected savings, the cause is almost always configuration: charge schedule not aligned to the tariff window, CT clamp direction wrong, eco mode disabled, or a firmware update that has reset values. We diagnose and fix this remotely in most cases. GivEnergy support →
Your Darlington installer has closed — we take over from here
County Durham and North Yorkshire had a mix of national and regional solar installers operating during the FiT era. Several have since closed. If your installer has gone into liquidation or stopped trading, we handle the full recovery — monitoring transfer, documentation, warranty claims, fault diagnosis, and ongoing maintenance.
Administration 2015. Government scheme installs across County Durham and North Yorkshire. Fronius inverters now 10+ years old.

Solis, Growatt, GivEnergy — we fix them all in Darlington
The Darlington area's install base leans toward Solis and Growatt on older FiT-era systems, with GivEnergy and Sunsynk growing on battery retrofits. Fronius appears on Mark Group installs. Each brand has different diagnostic methods, firmware management, and warranty processes — we know them all.
Areas around Darlington we cover
Darlington and the wider south Durham and North Yorkshire area. All at the same pricing — the only difference from our core Yorkshire coverage is a slightly longer booking window.
Not listed? If you're in south Durham or North Yorkshire, we likely cover you. Get in touch and we'll confirm availability. We also cover nearby Middlesbrough and Harrogate.
Just bought a house in Darlington with solar panels?
The Darlington area has a steady number of homes with solar panels from the FiT era and government schemes. When these properties change hands, the new owner rarely receives the MCS certificate, FiT registration details, monitoring login, or warranty information. Military housing around Catterick changes hands particularly frequently. We visit, identify every component, check performance, set up monitoring in your name, and hand over a written report.
GivEnergy battery systems in Darlington
GivEnergy battery retrofits are increasingly common across Darlington and south Durham — added to existing FiT-era solar systems on the 1960s–1980s housing stock. If your GivEnergy battery isn't delivering the tariff savings you expected, or the monitoring has never been properly set up, we provide specialist diagnostics, configuration, and ongoing support. Darlington is covered by our Teesside GivEnergy hub.
