I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.

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.

Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them

Dennis Brown · May 2026 Trustpilot

Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)

Tony Deacon · May 2026 Trustpilot

Contacted Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone

Phill · May 2026 Trustpilot

I've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues

michael fairhurst · May 2026 Trustpilot

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.

Mr Machin · May 2026 Trustpilot

After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.

Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.

Hugh Speirs · Apr 2026 Trustpilot

Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.

Christopher · Apr 2026 Trustpilot

I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration (their Trustpilot reviews don't lie!). So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.

This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.

Andy Thomas · Apr 2026 Trustpilot

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!

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

Both involve an on-site inspection. The difference is ongoing monitoring, priority response, and the relationship that follows. Both are available UK-wide.

No ongoing relationship

Best for: pre-acquisition due diligence, second opinions, one-time assessment. See independent 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 £795 per year. 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.
