Wow... a firmware update to my inverter sent the whole system into meltdown – the battery discharged, and the house seemed to be drawing power, and the solar, who knows where that was going? Aghhh... A short email exchange with Roland and Solar Tech Support sorted the problem... the firmware had reversed a setting (from when it was installed), and the CT clamp needed to be reversed. As soon as I had done that, the world returned to normal. Thanks, Roland; there is no way I would have come to that conclusion. Would I recommend them? You bet! Worth the fee? You bet, again!

I had a red status light on my GivEnergy battery pack and Ron at Solar Tech Support was a great help resolving the problem. He was able to do a remote diagnosis of the invertor BMS firmware and hardware and gave very quick practical and professional support. Thanks Rob

Great service from STS after a power cut and brownout left my GivEnergy inverters effectively useless. After filling the enquiry form out I was promptly given clear instructions by email explaining how to run their diagnostic software and they were working remotely in minutes. Soon after my inverters were back running again. Very helpful and knowledgeable people - thank you.

My old solax packed in and was replaced by solar tech support. I am impressed at the very short time scale, sorted in only 3 days. Some were quoting 2-3 weeks. The old unit and all the packing was taken away.

Local Knowledge

Solar in York — heritage homes, premium systems, and conservation considerations

York's solar installations tend to fall into two categories: carefully positioned panels on older properties in and around the city centre, and higher-spec systems on the newer housing estates to the north and east. The result is a higher proportion of premium inverter brands and a lower tolerance for bodged installations — which means the systems here tend to be well-installed but need specialist support when something goes wrong.

Heritage and conservation area installs

York has more conservation areas than most cities in Yorkshire. Many solar installations here went through additional planning processes to ensure panels sit within acceptable guidelines — rear-facing, ground-mounted, or on non-principal elevations. When these systems need component replacement, we match existing specifications precisely. Repairs and like-for-like replacements don't require new planning permission.

Higher proportion of SolarEdge and Enphase

York has significantly more SolarEdge and Enphase systems than we see in South Yorkshire. SolarEdge uses DC optimisers on each panel — essential on partially shaded period properties but each optimiser is a potential point of failure. Enphase microinverters appear on newer builds around Poppleton, Huntington, and Haxby. Both require panel-level diagnostics that differ from standard string inverter systems.

New-build estates driving battery uptake

Housing developments around Haxby, Strensall, Huntington, and the York outer ring increasingly come with solar as standard — typically 4–6kW arrays with GivEnergy or Sunsynk battery storage. These systems are modern and well-installed, but battery configuration problems are common: charge schedules not aligned to the occupier's tariff, CT clamps installed incorrectly during build, or firmware not updated post-handover.

Retrofit batteries on FiT-era systems

York's older FiT-era installations from 2012–2016 are prime candidates for battery retrofits. GivEnergy dominates this market — their AC-coupled systems bolt onto existing arrays without touching the original wiring. But we regularly see configuration issues on retrofits: export limiting set incorrectly, charge schedules fighting the FiT meter, or the installer leaving before the system was properly optimised for the homeowner's usage pattern.

Common Problems

What goes wrong with solar systems in York

York's mix of heritage properties and modern estates produces a distinct set of faults. These are the ones we diagnose most often.

1
SolarEdge optimiser failures on shaded period properties

Many York homes have SolarEdge systems specifically because they handle partial shading well — trees, chimney stacks, neighbouring rooflines on terraced and semi-detached properties. Those same chimney stacks and gables make the array perimeter longer, which is worth knowing if you are considering pigeon proofing for solar panels. Each panel has a DC optimiser, and when one fails, the SolarEdge portal flags the location but not always the root cause. We carry replacement optimisers and can usually diagnose and swap in a single visit. Panels underperforming →

2
New-build battery systems not configured for the occupier's tariff

A recurring issue on York's newer estates. The builder's installer commissions the battery system to a default schedule, hands over the keys, and moves on. The homeowner then runs for months (sometimes years) with charge schedules that don't match their actual electricity tariff — importing expensive peak electricity instead of using stored solar or cheap overnight rates. We reconfigure the entire battery system to match your tariff and usage patterns. GivEnergy support →

3
FiT meter conflicts on battery retrofits

York homeowners adding GivEnergy batteries to existing FiT-era systems sometimes find that the battery charges from the grid during the cheap-rate window, but the FiT meter records this as exported generation — inflating the export reading while costing real money. The fix involves CT clamp repositioning and charge schedule adjustment so the battery only charges from genuine solar surplus or verified cheap-rate imports. FiT payment problems →

4
Enphase microinverter and Envoy gateway faults

Enphase systems are becoming more common on York premium installs. Each panel has its own microinverter instead of a central unit. When a microinverter fails, that panel stops producing entirely. The Envoy gateway that manages the system can also lose connectivity or fail. These require specific diagnostic tools and Enphase-specific processes — different from standard string inverter or SolarEdge diagnostics. Inverter replacement in York →

Installer gone bust?

Your installer has closed — we take over from here

York was served by several installers that have since ceased trading. Whether your system was installed through a government scheme, a local company, or a national chain, the recovery process is the same — monitoring transfer (not GivEnergy), documentation rebuild, warranty verification, and ongoing support.

New homeowner

Just bought a house in York with solar panels?

York properties change hands frequently, and the solar documentation rarely follows. The situation is more complex here than in most areas — conservation area records, SolarEdge or Enphase monitoring accounts locked to the previous owner, FiT export tariff transfers, and sometimes heritage-specific installation conditions that affect what can be modified. We visit, identify everything, transfer accounts, and give you a complete picture.

FAQ

Solar repair in York — common questions

York sits about 40 minutes from our Leeds base, well inside our standard coverage area, and urgent faults are usually attended within one to two working days. For planned work, inverter replacements and annual maintenance visits are typically booked within the same week. A free remote diagnostic gives most people a same-day answer first, useful in York where the fault is often a single optimiser or microinverter rather than the whole inverter.
Conservation area rules affect new solar installations — not repairs to existing ones. If your panels were installed with the correct planning permissions, we can replace inverters, fix wiring faults, swap optimisers, and carry out all maintenance work without any additional planning approval. Where panels need physical replacement, we match the existing specification so there is no change to the roof appearance.
York is unusual in how many SolarEdge and Enphase systems we look after, where the fault often sits at optimiser or microinverter level rather than in the main unit, and no full replacement is needed. When the inverter itself has failed, replacement costs from £995 including the new unit, removal of the old one, installation, configuration, and commissioning. A free remote diagnostic pins down which component has failed before we quote. Inverter replacement in York →
