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.

STS were incredibly responsive and helpful In diagnosing an issue with my GivEnergy inverter. Although distance meant it was impractical for me to use them to fully solve the issue, I’m grateful for the help and detail they provided. Don is a real professional gent and a hero in my eyes.

Massively massively recommended. We had a big battery array (49kW across three phases) put in four years ago. c £35k cost. It’s been a total nightmare for many reasons, not least 1. our installer being totally useless and unresponsive and 2. Givenergy, our battery supplier, going bust. Long story short it had never worked anywhere near properly despite countless hours on phones and emails; the best we’d achieved was one third of the batteries working. Rather than write it off, I asked a PM friend to try to source someone who could come on site and review and revive the system. He found Solar Tech Support and Ron. Ron assured us he was the man to get it going again. After so many years of pain, I was not convinced but, true to his word, five hours later it was up and running. Lovely chap, super knowledgeable with a support team to lean on who are also clearly super technical. I honestly didn’t think there was much chance of getting this array going ever again so was absolutely delighted when Ron and team pulled it off. Bravo!

Peace of mind before winter or after a period of poor generation
Property sale preparation — documented proof the system has been professionally maintained
What we check on site
1
Roof and panel condition
Every panel is visually inspected from ground level and, where safely accessible, from roof level. We check for cracked cells, delamination, snail trails, hotspot discolouration, bird droppings, lichen, and general soiling. Mounting frames and fixings are inspected for corrosion, loosening, or weather damage. Cable trunking and clips are checked for UV degradation — a common issue after 5+ years where plastic clips become brittle and snap.
2
Electrical connections and safety
DC isolator tested for correct operation — this is the most common point of failure in older systems and a potential fire risk if the switch mechanism degrades. AC isolator and consumer unit connections checked for tightness. Earth bond continuity verified. All cable entry points and glands inspected for water ingress. MC4 connectors checked where accessible. Any signs of arcing, heat damage, or loose terminations are flagged as immediate priority.
3
Inverter and battery health
Inverter physically inspected — fan noise, ventilation clearance, heat discolouration on casing, and any visible error indicators. Current generation checked against expected output for your system size, orientation, and time of year. For battery systems: units physically inspected for swelling, damage, and cable condition; cell balance reviewed via the inverter interface; charge and discharge tested; battery health metrics recorded for comparison on future visits.
4
Settings, firmware, and monitoring
Export limit setting verified against your DNO agreement — this commonly drifts after firmware updates or smart meter installations. Charge and discharge schedules reviewed for your current electricity tariff (Octopus Flux, Intelligent Go, Agile, etc.) with recommendations if settings are suboptimal. Firmware version checked with update recommendation where beneficial. Monitoring portal verified — generation data recording correctly, alerts configured, account access confirmed.
5
Written maintenance report
Within 24 hours you receive a structured written report covering everything inspected: current condition, any issues found, photographs, and a prioritised list of recommended actions (immediate, short-term, advisory). This report serves as a maintenance record — useful for warranty purposes, property sales, and tracking system condition over time.

Frequently asked
A remote health check analyses your system's performance data, settings, and battery telemetry from monitoring software — no one visits your property. It's excellent for catching performance issues, configuration problems, and firmware concerns. A maintenance visit is an on-site service where an engineer physically inspects every component: panels, cabling, isolators, earthing, inverter, battery units, and connections. Physical issues like damaged cable clips, water ingress, corroded connectors, DC isolator degradation, and panel soiling cannot be identified remotely. For a full remote analysis, see the solar system health check.
Most manufacturers recommend an annual maintenance inspection. For systems under five years old in good condition with active monitoring, every 12 to 18 months is reasonable. Older systems, systems in exposed locations (coastal, rural, heavy tree cover), or systems with battery storage benefit from annual visits. The key issue is that physical degradation — cable clip failure, DC isolator wear, water ingress, mounting corrosion — won't show up in monitoring data. Only a physical inspection catches these.
We assess panel condition and soiling level as part of every visit. Light cleaning of accessible panels is included where it's safe to do so — typically ground-floor or easily accessed first-floor arrays. Heavy soiling, bird droppings, or lichen buildup that requires specialist cleaning equipment, scaffolding, or cherry picker access is noted in the report with a recommendation and estimated cost. We never use pressure washers on solar panels — only soft wash methods that comply with panel manufacturer guidelines, as high-pressure water can damage panel seals and coatings.
Yes — battery inspection is a core part of the visit for any system with storage. We physically inspect battery units for swelling, heat discolouration, damage, and cable condition. Cell balance is reviewed through the inverter interface. Charge and discharge cycles are tested. Battery health metrics (state of health, cycle count where reported) are recorded. We also review your charge schedules and tariff settings to confirm they're configured correctly for your current electricity tariff — many customers are on suboptimal schedules without realising.
This is a one-off visit — no ongoing commitment, no subscription, no direct debit. You book when you need it. Many customers simply book once a year on their own schedule. If you want continuous remote monitoring, an annual on-site visit, and priority response bundled together on an ongoing basis, ask us about the Solar Health Plan — but there is absolutely no obligation to sign up. The one-off maintenance visit is a complete, standalone service.
All major UK solar and battery brands: GivEnergy, Sunsynk, SolarEdge, Growatt, Solis, Fox ESS, Huawei, SMA, Fronius, Enphase, and Tesla Powerwall. We service string inverter systems, micro-inverter systems, hybrid systems with battery storage, and AC-coupled retrofits. Panel brands don't matter for servicing — the inspection is the same regardless of manufacturer. If the system was installed in the UK, we can service it.
