Book a proposal callBook a one-off auditI contacted STS when I was having problems with my GivEnergy AC3 inverter and they were extremely helpful. They took the time to properly investigate the system, talked me through a number of things we could try remotely, and ultimately inspected the system to establish what had gone wrong. They identified that the inverter’s battery board had failed beyond repair, while confirming that the two batteries themselves were still healthy. They also provided a clear report explaining their findings, which was particularly helpful given the current situation with GivEnergy. What impressed me most was their knowledge and willingness to help. They didn’t just give me a quick diagnosis — they took the time to understand the problem and explain the options available to me. I’m very pleased with the service I received from STS and would have no hesitation in recommending them to anyone needing help with a GivEnergy solar and battery system.
Any long suffering Givenergy customers are strongly recommended to use solar tech support. They fixed my battery issue in couple of hours.
A really big thank you to Ron and his team, he has vast amounts of knowledge and got my system back up and running, also good to get on with. I was absolutely lost as to know what to do, no help from installer and somehow came across Ron and am I glad I did. I would definitely definitely recommend him to anyone who has faults with there solar system, any make I would say. Thanks again Ron a pleasure meeting you.
When my GivEnergy battery started playing up it became basically useless and several companies I called said they couldn’t help. Solar Tech Support really knew their stuff, communicated very well and resolved the problem quickly. Without them I’d have had to buy a replacement battery.
Excellent knowledge and service. Ron responded to my initial query really quickly (same day), and confirmed that he could add extra panels and battery to my existing GivEnergy setup - something I’d been told by other installers wouldn’t be possible. Two weeks later (!), scaffolding was up and Ron and his team were on site to fit the extra 5 panels and two more GivEnergy batteries. I now have a truly optimised system, which has made the most of the south facing roof space I have, without having to start again with new kit. I’m now generating enough on the solar to fill my batteries, and avoid using the grid. I’ve also exported far more than before. Brilliant experience, well recommended.
Why independent commercial solar maintenance matters
Most commercial solar maintenance providers in the UK are also installers. That creates a structural conflict of interest — the same company that benefits from selling you new hardware is the one advising you on whether your existing equipment needs replacing.
STS is not tied to any manufacturer, installer, or distribution network. We carry out inverter replacements, component swaps, and hardware repairs — but we have no incentive to recommend work that is not necessary. When we say a component needs replacing, it is because it does — not because we profit from a preferred supplier relationship.
That independence is why our inspection reports carry weight with landlords, facilities managers, and procurement teams. If you need an objective assessment of a commercial solar asset — whether for acquisition due diligence, insurance compliance, or performance benchmarking — our reports are written without a commercial agenda.
We work with all major inverter and battery brands used in UK commercial installations. Our engineers are experienced with three-phase systems, string and micro-inverter configurations, large-scale battery arrays, and the monitoring platforms that connect them. Read more about how we work.
Operations & maintenance contracts
Annual on-site inspection, real-time fault monitoring, performance reporting, and priority access to our engineering team. Structured contracts with clear SLAs — no rolling subscriptions, no hidden fees.
Emergency commercial repair
System down, inverter failure, safety alarm. Same-day remote triage, next-business-day on-site for contract holders. Non-contract emergency callouts available subject to availability.
System takeover
Inherited a building with solar. Original installer gone. Current O&M provider not performing. We conduct a baseline audit, get monitoring online, and transition the system onto an STS contract.
Independent performance audit
One-off on-site inspection and performance assessment. Due diligence before acquisition, a second opinion on system performance, or an independent report for insurance or compliance purposes.
Facilities managers
You are responsible for the solar asset on a commercial building and need a reliable, independent maintenance partner. You want clear SLAs, scheduled inspections, automated fault alerts, and a single point of contact when something goes wrong.
Property owners & landlords
You own or have acquired a building with a commercial solar installation. You need to know what condition it is in, whether it is performing to specification, and who is going to maintain it going forward. You may need an independent audit for insurance or tenancy compliance.
UK businesses with solar
Your business invested in solar to reduce energy costs. The installer who fitted it may no longer be trading, or the commercial solar maintenance they promised has not materialised. You want an independent provider who will keep the system running and tell you the truth about its condition.
How we work
No account setup, no minimum term for one-off audits. O&M contracts are agreed in writing before any work begins.
Tell us about your system — size, brand, age, current maintenance arrangement (if any), and what you need. We will confirm whether an O&M contract, a one-off audit, or an emergency callout is the right starting point.
We provide a written proposal covering exactly what is included, the annual cost, SLA terms, and any additional services available. Nothing starts until both sides have signed off.
For new O&M contracts and system takeovers, we begin with a baseline inspection — a full assessment of current system condition, monitoring status, and any faults or underperformance. This establishes the starting point for ongoing maintenance.
Scheduled annual inspections, real-time monitoring (where the equipment supports it), written reporting after every visit, and priority access to our engineering team for faults and emergencies. If the system needs connectivity setup to enable remote monitoring, we can arrange that for an additional fee.
