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.

What 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.

Andrew Palmer · May 2026

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.

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!

Thank you for your diligence. On this occasion the battery was able to be saved but they have given a route to hopefully arrange a repair from the manufacturer.

Ron responded very promptly regarding my GivEnergy battery issue, his knowledgeable diagnosis was spot on and resolved the issue on first attempt. Would recommend to any and all.

What's included in your operations and maintenance contract

Annual on-site inspection

A full physical inspection of every component — panels, cabling, trunking, DC and AC isolators, inverters, battery units, earthing, and mounting systems. The engineer checks for UV degradation, water ingress, heat damage, cable clip failure, corrosion, fan wear, and any signs of physical deterioration that monitoring cannot detect.

Real-time fault monitoring

Where the installed equipment supports remote connectivity — most modern commercial inverters do — we configure automated fault alerts that notify the STS engineering team when the system reports an error, drops offline, or underperforms. Faults are often identified and diagnosed before anyone on site notices a problem.

Performance reporting

A written report after each annual inspection covering: system condition, generation performance against expected output, any faults or underperformance identified, photographs, and a prioritised list of recommended actions (immediate, short-term, advisory). Structured for use in building management, insurance, and compliance reporting.

Priority fault response

O&M contract holders receive priority access to the STS engineering team for fault diagnosis and emergency repair. Same-day remote triage for reported faults, with next-business-day on-site attendance where remote resolution is not possible. Response times confirmed in your contract SLA.

Settings & configuration audit

At each inspection: export limits verified against DNO agreement, charge and discharge schedules reviewed, firmware versions checked with update recommendations, monitoring portal configuration confirmed, and CT clamp orientation validated. Incorrect settings are the single most common cause of commercial solar underperformance.

Compliance documentation

Each inspection report serves as evidence of ongoing professional maintenance. Suitable for landlord requirements, insurance renewal, building management reporting, and audit purposes. We can provide additional documentation confirming system safety status on request.

Available add-ons

These services are not included in the standard contract but can be added at any time. All are priced separately and confirmed before work begins.

Thermal imaging survey

Infrared inspection of panel array to identify hotspots, micro-cracks, bypass diode faults, and cell-level degradation. Particularly valuable for large rooftop arrays where individual panel inspection is time-consuming.

Panel cleaning

Professional cleaning of panel surfaces. Light cleaning of accessible panels is included in the annual inspection where safe. Heavy soiling, lichen, bird droppings, or large arrays requiring specialist access are quoted separately.

Connectivity setup

If the system is not currently online-connected and the equipment is capable of remote monitoring, we can configure the connection. This enables the real-time fault monitoring included in your contract.

Ad-hoc site visits

Additional on-site visits beyond the scheduled annual inspection. Used for post-storm checks, component replacement oversight, or follow-up on specific issues identified in the annual report.

Bird proofing

Mesh guard installation to prevent nesting under rooftop panels. Assessed during the annual inspection and quoted if recommended. See bird mesh installation for more detail.

What happens during the annual inspection

1
Pre-visit preparation

Before arriving on site, we review the monitoring data from the previous 12 months — generation trends, fault history, and any alerts triggered since the last inspection. This means the engineer arrives informed and can focus the on-site time on areas that need attention.

2
Physical component inspection

Every accessible component is physically inspected: panels for cracks, delamination, hotspots, soiling, and bird damage; cabling and trunking for UV degradation and mechanical wear; DC and AC isolators for operation and heat damage; inverters for fan operation, error indicators, ventilation, and physical condition; battery units for swelling, heat discolouration, cable integrity, and cell balance.

3
Electrical safety verification

Earth bond continuity checked. Cable entry points and glands inspected for water ingress. Connection tightness verified at accessible terminals. Any signs of arcing, heat damage, or deterioration flagged immediately. This is the part of the inspection that protects against electrical fire risk — and the part that remote monitoring cannot replicate.

4
Settings and configuration audit

Export limits verified against the DNO connection agreement. Charge and discharge schedules reviewed against the building's tariff. Firmware versions noted with update recommendations where applicable. Monitoring portal and alert configuration confirmed. CT clamp orientation validated — incorrect CT clamp direction is the most common misconfiguration on commercial systems and directly causes export revenue loss.

5
Written report with prioritised actions

Within five business days you receive a structured written report covering: current condition of every inspected component, generation performance analysis against expected output, any faults or underperformance identified, photographs, and a prioritised recommendation list — immediate actions (safety or revenue-critical), short-term actions (schedule within 3 months), and advisory notes (monitor and reassess).

Commercial solar O&M contract vs one-off audit

FAQ

Frequently asked

A standard STS O&M contract includes an annual on-site inspection of all inverters, panels, cabling, isolators, and battery units; real-time fault monitoring with automated alerts where the equipment supports remote connectivity; a written performance and condition report after each inspection; compliance documentation for insurance and landlord requirements; and priority access to the STS engineering team for fault response and emergency repair. Additional services such as thermal imaging, panel cleaning, and ad-hoc site visits are available as add-ons.
Annual O&M contracts start from £10/kWp/annum. The exact cost depends on system size, number of inverters, site accessibility, battery storage complexity, and whether multi-site arrangements are required. All pricing is confirmed in a written proposal before any contract begins. There are no hidden fees — what is quoted is what you pay.
An STS engineer visits the site and physically inspects all system components: panels for condition and soiling, cabling and trunking for degradation, isolators and switchgear, inverters for fan operation and error indicators, battery units for physical condition and cell balance, and earthing and bonding. The engineer also audits all system settings — export limits, charge schedules, firmware versions, and monitoring configuration. A written report with photographs and prioritised recommendations follows within five business days.
Where the installed equipment supports remote connectivity — most modern commercial inverters do — we configure automated fault alerts that notify the STS engineering team when the system reports an error, drops offline, or underperforms against expected output. This allows us to identify and often diagnose faults before anyone on site notices a problem. If the equipment is not currently online, we can assess whether connectivity can be established and quote for the setup separately.
Standard contracts are annual with no automatic renewal — you choose to continue each year. Multi-year contracts are available at a reduced rate for clients who prefer longer-term arrangements. There is no exit penalty on annual contracts. We retain clients because the service is good, not because of contractual lock-in.
Yes. Each annual inspection report is structured to serve as evidence of ongoing professional maintenance. We can provide documentation confirming that the system has been inspected, that it is operating safely, and that any identified issues have been flagged with recommendations. This documentation is suitable for landlord compliance, insurance renewal, and building management reporting.
