Full-lifecycle support for commercial solar assets:
Request a proposalBook a one-off auditWhat a fantastic service. Had my fault diagnosed within minutes and actually managed to resolve the issue remotely within a few minutes more. This guy is like a “Solar Batman” helping consumers fix their problems using his extensive industry knowledge and expertise. Outstanding service. Thank you so much.
I reached on behalf of a friend, who had lost control of their battery following a storm. A couple giv energy “dealers” had attempted and said different fixes. None worked. Solar tech support solved it remotely on the first attempt almost instantly. Genuinely a 10/10 service.
Ron is incredibly knowledgeable about solar installs in general but knows givenergy products inside out and the key personnel that worked there from the start to the end. My problem was spurious in its nature but Ron spotted it straight away when he understood the installation details. In essence the installers didn’t fit the correct trip switch. He also gave me hope that in the future hardware repairs could be possible but it’s still early days. This guy really is in the know and keen to sucas a business If you need help don’t hesitate
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.
I’ve used Ron a couple of times regarding issues with my Givenergy inverter and batteries after Givenergy went bust. My system stopped working properly so it was a stressful time but Ron resolved the issues and got my system working properly again. He’s really helpful and knowledgeable and I wouldn’t hesitate to recommend him and to use him again if the need arose.
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.
