We decided to treat ourselves to an upgrade to our existing solar system, and after a little searching, it became evident that Ron and his team provide the service and support we required. Decommissioning and recommissioning our new SunSynk inverter and a wall-mounted Fogstar battery (which is of substantial size and weight compared to the original) was completed swiftly and competently. The installation was perfectly executed, and all upgraded paperwork for the increased battery export capacity was handled by Ron. I have no hesitation in recommending this team of support technicians to you.

Very speedy response. Handled by a real human who took my system through a logical process with the desired outcome within minutes of them accessing my inverter settings. Ron passed me on to Ash, they are both ex-Givenergy people who clearly know their stuff and can give the reassurance of proper technical support now that the Givenergy support desk has closed. A worthwhile investment in ensuring my expensive kit is kept fully functioning.

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.

Very happy with the support I got from Ron at Solar Tech Support with my GivEnergy battery problem. The battery having operated perfectly for 3 years suddenly stopped discharging. He sorted it out in minutes.

Paul Elliott · Sep 2026 Google

Absolutely fantastic customer service. The team were incredibly helpful, responsive and genuinely willing to do everything they could to help get things sorted. With all the uncertainty surrounding the future of GivEnergy at the moment, it was particularly reassuring to have people who were knowledgeable, approachable and prepared to step in when needed. After a glitch with my firmware update caused problems with my system, these guys really did come in and save the day. They took the time to investigate the issue, explain what was happening and work towards getting everything back up and running. It’s refreshing to deal with a company that genuinely seems to care about its customers and is willing to go the extra mile when something goes wrong. Superb service from start to finish. Many thanks for all the help and support — it’s very much appreciated. Highly recommended.

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.

Local Knowledge

Solar in Derby — strong adoption across every era of housing

Derby's solar landscape is more varied than most cities in our extended coverage. The city has substantial FiT-era installs on its Victorian and Edwardian terraces, government scheme systems across the suburban estates, and a wave of modern hybrid installs with battery storage on the new-build developments springing up around the southern and eastern fringes. Each era of installation brings different brands, different failure patterns, and different support needs.

Victorian and Edwardian terraces with ageing FiT arrays

Derby's older neighbourhoods — Normanton, Pear Tree, Darley Abbey, and parts of Littleover — have a high concentration of FiT-era solar from 2011–2015. Compact 2–3kW arrays on narrow south-facing roofs with single string inverters, typically Solis or Growatt. These systems have been generating reliably for a decade, but the inverters are now reaching end of life. Replacement is straightforward and FiT payments continue unaffected.

Suburban estates with government scheme installs

The 1960s–1980s suburban belt — Alvaston, Sinfin, Chaddesden, Mackworth — was heavily targeted by ECO and Green Deal solar programmes. Systems are typically 3–4kW with budget string inverters installed by national companies at volume. Many of those companies have since closed, leaving homeowners with ageing hardware and no support. Documentation is often missing, monitoring was never set up, and faults go undetected.

New-build developments with hybrid battery systems

Developments around Chellaston, Mickleover, and the southern fringes of Derby increasingly include solar panels with battery storage as standard — typically 3–4kW arrays with GivEnergy hybrid inverters and 5.2kWh or 8.2kWh batteries. The hardware is modern and reliable, but developer handovers leave systems on factory defaults: charge schedules not configured, CT clamps not calibrated, and tariff integration not set up. These systems work but underperform until someone configures them properly.

Remote diagnostic as a practical first step

Derby is at the edge of our on-site coverage — about 90 minutes from our Yorkshire base. For most faults, a free remote diagnostic is the smartest first move. We analyse monitoring data, generation meter readings, fault codes, and firmware versions remotely. This identifies the fault before we travel, so we arrive with the right parts and complete the job in a single visit. For configuration issues on battery systems, the fix is often entirely remote.

Common Problems

What goes wrong with solar systems in Derby

Derby's three-era installation landscape creates a distinct fault profile. FiT-era systems are hitting inverter failure age, government scheme installs have documentation gaps, and modern battery systems need proper configuration. These are the faults we see most often.

1
String inverter failure on FiT-era systems across the city

Derby's 2011–2015 FiT-era systems are reaching the point where string inverters fail. Solis, Growatt, and older Fronius units have a practical lifespan of 10–15 years, and many are now showing symptoms: blank displays, zero generation, intermittent fault codes, or earth fault trips. The panels are typically fine — replacement with a modern hybrid inverter restores generation and your FiT payments continue unaffected. We stock the most common models and can usually complete a swap in a single visit. Inverter replacement →

2
Battery systems on new-build estates not saving money

A growing complaint from homeowners on Derby's newer developments. The system was sold as a money-saver — store cheap-rate electricity overnight, use solar during the day, export the surplus. In practice, many systems import from the grid during peak hours because the charge schedule doesn't match the tariff, the CT clamp is reading incorrectly, or eco mode settings weren't enabled. We diagnose and fix these configuration issues remotely — no on-site visit needed in most cases. GivEnergy support →

3
Government scheme systems with no monitoring and no documentation

Installations across Alvaston, Sinfin, Chaddesden, and Mackworth through ECO and Green Deal programmes were done at volume. Monitoring was rarely set up, MCS certificates were lost, and warranty registration was left to the homeowner. When the inverter fails a decade later, there's no paper trail and the installer has closed. We identify the hardware, rebuild the documentation, check manufacturer warranties, and set up proper monitoring so you know what your system is actually producing. Monitoring offline guide →

4
Partial shading on terraced streets reducing output

Derby's older terraced streets — particularly in Normanton and Pear Tree — have tightly packed rooflines where chimney stacks, aerials, and neighbouring properties cast shadows across panels at certain times of day. On standard string inverter systems, shading on one panel drags down the output of the entire string. If your generation is noticeably lower than expected, shading analysis is part of every diagnostic we run. In some cases, optimiser retrofits or panel reconfiguration can recover significant lost output. System underperforming →

Installer gone bust?

Your Derby installer has closed — we take over from here

Derby's solar systems were installed by a mix of national companies and regional outfits — several of which have since gone into administration or been dissolved. Mark Group operated heavily across the East Midlands through government schemes. Solarplicity had customers across Derbyshire. If your installer has closed, any surviving manufacturer warranty depends on the brand, and we handle the full recovery.

Most common
Mark Group

Administration 2015. Leicester-based — Derby was core territory. Government scheme installs with Fronius inverters now 10+ years old.

Mark Group guide →
Solarplicity

Dissolved November 2023. Combined energy supplier and solar installer. 7,500+ customers nationally — Derbyshire properties included.

Solarplicity guide →
Solar Plants

Dissolved February 2022. Wales-based but installed across the Midlands and northern England.

All Brands

Solis, Fronius, GivEnergy — Derby's three-era brand mix

Derby's solar brands reflect the city's installation timeline. Older FiT-era systems run Solis, Growatt, or Fronius string inverters. Government scheme installs often have Fronius IG units from Mark Group rollouts. Newer battery systems predominantly use GivEnergy hybrid inverters. We diagnose, repair, and replace every brand — no manufacturer affiliation, no bias. GivEnergy Ltd entered administration in April 2026, so a manufacturer warranty claim is no longer possible. Depending on how the system was bought, cover may still come from your installer's workmanship guarantee, an insurance-backed guarantee, Section 75 if you paid by credit card, or the MCS Consumer Code. We help you work out which route may still apply, and we supply and fit replacement GivEnergy hardware at fixed prices.

Solis, Growatt — budget string inverter replacement on FiT systems
Fronius — IG, IG Plus, Primo, Symo replacement and repair
GivEnergy — battery diagnostics, configuration, firmware, replacement hardware supplied and fitted
SolarEdge, Sunsynk, Fox ESS, Huawei — all supported
Warranty claims for manufacturers still trading: Sunsynk, SolarEdge, Growatt, Solis, Enphase

FAQ

Solar repair in Derby — common questions

Derby sits in our extended coverage, about an hour and a half from our Yorkshire base, so urgent on-site attendance is usually within three to four working days. That is exactly why we lead with the free remote diagnostic here: it identifies the problem same-day and tells us precisely what parts and time the visit needs, so nothing is wasted when we do travel.
Yes. We cover Derby and the wider Derbyshire area including Belper, Ripley, Ilkeston, Long Eaton, Alvaston, Mickleover, Littleover, Spondon, Duffield, and surrounding areas. For properties further into the Peak District, a remote diagnostic is often the most practical first step. Remote diagnostics are available UK-wide regardless of location.
Derby systems run from compact 2kW FiT-era arrays on terraced streets to modern 6kW hybrid setups on new-build estates, so the replacement cost genuinely depends on what is on your roof. Replacement costs from £995, which includes the new unit, removal of the old one, installation, configuration, and commissioning. Larger and hybrid units sit above that, in line with brand, model, and system size. We confirm the exact requirement with a free remote diagnostic before quoting. Inverter replacement service →
Yes. GivEnergy is the most common battery brand we see across Derby, both on new-build installations and retrofits to existing panels. Common issues include the battery not charging from solar, importing from the grid during peak hours when it shouldn't, and charge schedules not aligned to the homeowner's tariff. Most configuration faults can be diagnosed and fixed remotely. If the issue is hardware — a faulty battery module or inverter — we attend on-site with replacement parts. GivEnergy support →
