Solar Repair & Support in Hull

Hull and the East Riding have some of the best solar conditions in Yorkshire — flat terrain, open skies, and no hillside shading to contend with. The city saw heavy uptake during the FiT era, with thousands of systems installed on terraces, semis, and social housing between 2010 and 2014. Those systems are now 10–15 years old, and the inverters are reaching end of life. We're about an hour from our Leeds base and cover Hull regularly.

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

Dennis Brown · May 2026 Trustpilot

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.

Hugh Speirs · Apr 2026 Trustpilot

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!

Local Knowledge

Solar in Hull — high yield, ageing hardware, and orphaned systems

Hull was one of the earliest adopters of residential solar in Yorkshire. The city council backed several large-scale installation programmes, and private installers saturated the market during the peak FiT years. The result is a huge install base — but most of that hardware is now over a decade old. The panels are usually still fine; it's the inverters, wiring, and monitoring that need attention.

☀️
Flat terrain, maximum solar yield

Hull's flat geography is a genuine advantage for solar. No valley-side shading, no steep hillside orientation issues — most roofs get unobstructed sun from morning through afternoon. Systems here typically generate 10–15% more per kilowatt than equivalent arrays in the hilly parts of West and South Yorkshire. When a Hull system underperforms, the cause is almost always hardware failure rather than site conditions.

🏠
Massive FiT-era install base

Hull saw enormous solar uptake between 2010 and 2014 — council-backed programmes, government energy efficiency schemes, and private installers all competing for the generous Feed-in Tariff rates. The typical Hull installation from this era is a 2–4kW array with a Fronius, Solis, or Growatt string inverter on a semi-detached or terraced property. The panels have 25-year warranties and are usually fine; the inverters have 5–10 year warranties and many have already exceeded their expected lifespan.

🌊
Humber estuary exposure

Properties closer to the Humber — particularly in Hessle, North Ferriby, and the eastern parts of Hull — are exposed to estuarine weather conditions. Wind-driven moisture can corrode DC connectors, junction boxes, and panel frame earthing over time. This doesn't affect most systems, but where we see unexplained generation drops on Hull properties, connector corrosion is a more common cause than in inland areas.

🔋
Battery retrofits gaining momentum

Hull's FiT-era systems are prime candidates for battery retrofits. These arrays generate well but export most of their electricity for a few pence per unit. Adding a GivEnergy AC-coupled battery captures that surplus for evening use or cheap-rate arbitrage. The flat terrain and consistent generation profile means battery economics work particularly well here — but only if the configuration is set up correctly for the homeowner's tariff.

Services

What we do in Hull

Hull has a large base of solar installs from government-backed schemes and the FiT era. Many of these systems are now past their initial warranty period and need specialist support. We remote-diagnose before every visit — checking fault codes, generation trends, and monitoring data. No call-out fees. Written pricing before work starts.

Common Problems

What goes wrong with solar systems in Hull

Hull's solar issues are almost entirely age-related. The systems were well-installed on favourable terrain — but the hardware is reaching its limits after a decade-plus of continuous operation.

1
Ageing string inverters reaching end of life

The single most common issue in Hull. Thousands of FiT-era systems installed between 2010 and 2014 used Fronius, Solis, or Growatt string inverters with 5–10 year expected lifespans. Many have now exceeded that. Symptoms: blank display, no generation, intermittent fault codes, or the system switching off during peak sun and restarting later. These units are past economic repair — a modern replacement restores full generation and adds monitoring capabilities the original never had. Inverter replacement →

2
Systems running unmonitored for years

Many Hull FiT-era systems were installed before cloud-based monitoring was standard. The homeowner has no idea what their system generates, whether it's performing as expected, or whether a fault has been developing over months. We've attended properties where the system had been completely offline for over a year without the homeowner realising — the inverter display was facing the wall in a utility cupboard. We set up modern monitoring and establish a performance baseline. Fault diagnosis →

3
DC connector and junction box corrosion

More common in Hull than inland areas. Exposure to Humber estuary weather — wind-driven moisture with trace salt content — can corrode MC4 connectors, junction box seals, and panel frame earthing bonds over a 10–15 year period. Symptoms: intermittent generation drops that don't correlate with weather, or arc fault warnings on systems with detection. We inspect the full DC wiring chain, replace corroded connectors, and reseal junction boxes. Annual maintenance →

4
FiT export payments — confusion after inverter replacement

Hull homeowners on FiT sometimes worry that replacing an inverter will affect their tariff payments. It won't — the FiT is tied to the MCS installation certificate, not the specific hardware. Your generation and export payments continue at the same rate after an inverter swap. We provide confirmation documentation for your energy supplier and ensure the generation meter continues to read correctly post-replacement. Inverter replacement →

Installer gone bust?

Your Hull installer has closed — we take over from here

Hull's early adoption of solar means many systems were installed by companies that peaked during the FiT boom and no longer exist. National operators, council scheme subcontractors, and local firms — many have closed. Your system still works regardless of who installed it, and the recovery process is straightforward.

Installer not listed? The recovery process is the same regardless of who installed your system. Full installer gone bust guide or book a call.

All Brands

Fronius, Solis, GivEnergy — Hull's brand mix

Hull's solar brand mix reflects its installation timeline. Older FiT-era systems predominantly use Fronius IG and IG Plus inverters, or budget Solis and Growatt units. Newer battery retrofits are almost exclusively GivEnergy. We support all of them — and when an old inverter fails, we can replace it with a modern hybrid unit that adds battery capability to the existing array.

Fronius — IG, IG Plus, Primo, Symo replacement and repair
Solis, Growatt — budget inverter replacement on FiT systems
GivEnergy — battery retrofit, hybrid inverter, configuration
SolarEdge, Sunsynk, Fox ESS, Huawei — all supported
19+ brands — independent, no manufacturer bias

New homeowner

Just bought a house in Hull with solar panels?

Hull has one of the highest densities of residential solar in Yorkshire. If you've just bought a property here, there's a good chance it has panels — and a good chance nobody has maintained or monitored them in years. The installing company may no longer exist, the FiT paperwork may be missing, and there's no way to tell from the ground whether the system is performing. We visit, check everything, and hand you back a system that's properly managed.

FAQ

Solar repair in Hull — common questions

Hull is about an hour from our Leeds base — at the outer edge of our standard coverage area but a regular part of our schedule. For urgent faults like a dead inverter or total generation loss, we can usually attend within two to three working days. Scheduled work such as inverter replacements and annual maintenance is typically within the same week. A free remote diagnostic can identify most faults same-day if you need answers before the on-site visit.
Yes. Hull and the East Riding have some of the best solar conditions in Yorkshire. Flat terrain means no hillside shading, and the open landscape gives most properties unobstructed south-facing roofs. Systems here tend to generate more per kilowatt installed than equivalent arrays in the hilly parts of West Yorkshire. The trade-off is exposure — coastal winds and weather can affect panel fixings, wiring, and junction boxes over time, particularly on properties closer to the Humber.
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. Many Hull systems have Fronius, Solis, or Growatt string inverters from FiT-era installations that are now past economic repair. A free remote diagnostic confirms exactly what's needed before we quote. Inverter replacement service →
