Contacted Solar Tech about my Givenergy battery storage system that wasn't working. Battery status was "idle". Given the company Givenergy had gone bust, I need independent quality technical help. Very patient and clearly very knowledgeable about battery systems Ron diagnosed possible issues and suggested several possible remedies. Worked our way through them and fortunately it began to work. The fault was very specific and only an experienced engineer would have thought to check. Suffice to say I'll be back if I need independent support again. Lastly you only pay if there is a solution. Outstanding.
My Givenergy battery stopped working nearly a month ago. After unsuccessfully reaching out to my installer, who looks like he's also busted, I found Solar Tech Support on a Google search. They fixed my issue in a couple of hours. Any frustrated Givenergy customers, I highly recommend these guys.
Excellent response to diagnose a problem on our SolarEdge installation. Kept us informed at every step. Diagnosis quickly completed and solution implemented.
Prompt and useful support regarding my Sunsynk system lack of performance. Ronald simplified the technical issues to make them understandable. Many thanks, looking forward to follow up.
Amazing support, went out of his way to help try and get us back up and running
What a fantastic service. Had my fault diagnosed within minutes and actually managed to resolve the issue remotely within a few minutes more. This guy is like a “Solar Batman” helping consumers fix their problems using his extensive industry knowledge and expertise. Outstanding service. Thank you so much.
Excellent service from Solar Tech Support. Extremely quick to respond, easy to deal with and clearly very talented engineers. They were persistent throughout a complex GivEnergy battery issue and resolved everything completely. Highly knowledgeable, professional and reassuring support from start to finish. Highly recommended.
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.
Ron made more sense in 20 mins than our installer has done over the last 12 months There is a jungle out there and you need someone like Ron to give a comprehensive overview and solution
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. 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!

What actually happened to Solarcentury
Solarcentury was a genuine UK solar pioneer — founded in 1998 by Jeremy Leggett, it grew into the country's largest solar company and put solar on roughly 25,000 homes, including its own C21e solar roof tiles. It did not go bust. What happened is that it left the home-solar market, and the consumer brand was wound down — which is why former customers can no longer find anyone to call.
Public record — Companies House
Solarcentury's residential installation arm — Solarcentury Microgen (UK) Ltd — was sold to Sweden's Svea Solar and renamed Svea Solar UK Ltd (company 11068740). Solarcentury itself stepped back to focus on large-scale solar farms.
The Norwegian renewables group Statkraft bought Solarcentury for around £118 million. Statkraft develops utility-scale solar, not domestic rooftop aftercare, and the Solarcentury consumer brand was retired. Solar Century Holdings Ltd (03570325) remains active as part of Statkraft.
The UK entity that had taken on Solarcentury's residential customers (formerly Solarcentury Microgen UK Ltd, company 11068740) was dissolved at Companies House — so the residential successor is gone too.
What it means for you: there is no Solarcentury to ring, and the residential successor has been dissolved. Your panels, your generation and your Feed-in Tariff are unaffected — but day-to-day support, repairs and ageing-inverter swaps now need an independent engineer.
What this means for your Solarcentury system
The brand is gone, but your system isn't. Most Solarcentury home installs are now 8–16 years old, so here's what's affected and what isn't.
Installer support and aftercare — gone. There is no Solarcentury, and the residential successor (Svea Solar UK Ltd) was dissolved in 2024. No one from that chain to call for faults or advice.
Workmanship warranty — the original installer cover is effectively gone. If your install came with an insurance-backed guarantee (IBG), check the certificate — IBGs are designed to survive the installer closing.
Original monitoring — early systems often had little or no monitoring, or used a portal that no longer exists. It can usually be added or re-established.
Your panels and generation — Solarcentury fitted quality panels; the vast majority are still performing well, and many carry a 10–25 year product and performance warranty that is independent of the installer.
Manufacturer warranties — separate from the installer. Panels are often still covered; string inverters are usually past their 5–12 year term, which is why they're the part that now needs attention.
Your Feed-in Tariff — the FIT accreditation stays with you and your property. A like-for-like inverter swap (same or lower capacity) does not affect it.
MCS registration — permanent and searchable at mcscertified.com, even though the installer has gone.
Five steps to take over your Solarcentury system
Work through these in order. The aim is simple: confirm what you've got, get it generating reliably again, and protect your Feed-in Tariff income.
Dig out the MCS certificate, Feed-in Tariff registration, and handover pack — they name the installer and list your panel and inverter models. If they're missing, search mcscertified.com by postcode and install date. Our Documentation Recovery guide covers the full process.
Before spending anything, find out the real state of the system — is it generating, is there a fault, what's the inverter and monitoring status. A remote diagnostic is free: no fix, no fee. If we can sort it remotely it's a flat £75; if it needs hands-on work we quote that up front.
The ageing string inverter — SMA Sunny Boy, Fronius, Power-One/ABB and similar — is the usual failure point on a Solarcentury-era system. We replace it like-for-like or with a modern equivalent sized to your existing panels, keeping the same or lower capacity so your Feed-in Tariff is unaffected. Inverter replacement starts from £795 including supply, fit and commissioning.
If the system had monitoring registered under Solarcentury, it can be claimed into your own account; if it had none, a modern monitoring device can be retrofitted to most inverters. Follow our monitoring recovery guide, and rebuild any missing MCS or FIT paperwork while you're at it.
An older array benefits from an occasional check — DC isolators (a known weak point on systems of this age), MC4 connectors, mounting, and generation against expected. An independent annual maintenance visit catches problems early and keeps your FIT income flowing. From £195 per year.
Services for former Solarcentury customers
We support solar systems regardless of who installed them. These are the services most relevant to an ageing Solarcentury system.
Not sure if your Solarcentury system is still working properly? An engineer call gives you a clear picture — faults, inverter status, monitoring, and a written action plan. Free: no fix, no fee.
Remote diagnostic →The classic Solarcentury job: a 12-year-old string inverter that's failed or throwing faults. We swap it FIT-safe — same or lower capacity — and re-commission. From £795 supplied and fitted.
Inverter replacement →The full picture for an orphaned system — fault diagnosis, monitoring re-established, documentation rebuilt, warranty status checked, and a written condition report you can act on.
System recovery →If your monitoring was registered under Solarcentury, we move it to your own homeowner account — or retrofit a monitoring device if the original system never had one.
Monitoring transfer →Your panels may still hold a 10–25 year manufacturer warranty even though the installer has gone. If there's a panel or component fault, we check what's claimable and handle the claim.
Warranty support →An older system with no installer behind it benefits from a yearly health check — DC isolators, connectors, and generation against expected — to protect your Feed-in Tariff income. From £195.
Annual maintenance →Wherever Solarcentury fitted you, we can help
Solarcentury installed nationwide, so most of our help for former customers starts with a free remote diagnostic, available anywhere in the UK. For hands-on work — an inverter swap or an on-site inspection — we're based in Yorkshire and cover the surrounding region, and can advise on the rest of the country case by case.
Guides for customers of installers that have closed
Step-by-step process for reclaiming an inverter account locked under a defunct installer — or adding monitoring to a system that never had it.
Monitoring recovery guide →Your panel and inverter warranties are independent of Solarcentury. Here's how to claim directly with the manufacturer — what you need and how to escalate.
Warranty claim guide →What you can and can't change on a FIT-accredited system — and how a like-for-like inverter swap keeps your payments intact.
FIT system guide →Missing your MCS certificate or FIT paperwork from Solarcentury? Most installation documents can be recovered — here's the full process.
Documentation guide →Common questions from Solarcentury customers
Tell us about your Solarcentury system
Let us know what you've got — roughly when it was installed, the inverter brand if you can see it, whether it's still generating, and what paperwork you have. We'll come back the same day with a clear plan to get it sorted.
