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.

Absolutely amazing service. Ive had a couple of issues with my Givenergy system and couldn't manage to get in touch with Givenergy after they went bust. So I was searching on Google and came across Rons number. I sent Ron a WhatsApp message and got a prompt reply and he resolved the problem I had with my system. I can't recommend Ron enough its not often you get such a good service in this day and age. If you are experiencing issues with your solar system Ron is the man to contact.
What an Amazing service and so helpful . I have had problems with a faulty GivEnergy inverter and Ron has been so diligent in investigating and reporting on it . I’d give him more than 5 stars if I could for his help in diagnosis and potential solution. Thoroughly recommend .
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.
Our SolarEdge PV system with LG batteries had its first hiccup after 8 years of hard work. The Inverter failed. Fortunately I found Solar-Tech-Support who diagnosed the problem very quickly, ordered a replacement unit and fitted it shortly after we received the unit from SolarEdge. Very thorough and professional approach. Thank you, a solid 5 star recommendation.
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.
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 £95; 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 £995 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 £995 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.
