Annual solar maintenance visit On-site inspection, service, and report
A thorough on-site inspection of your entire solar and battery system. We physically check every component — panels, cabling, isolators, inverter, battery, earthing — verify all settings, and provide a written maintenance report with any actions needed.
On-site visit
What happens on the day:
Typical visit duration: 1–2 hours depending on system size. The written report follows within 24 hours.
What's included
Physical Panel Inspection
Visual inspection of all panels for cracks, delamination, hotspots, snail trails, bird damage, and soiling. Frame and mounting condition checked. Cable clips and trunking inspected for UV degradation or mechanical damage. Light cleaning included where safe and accessible.
Electrical Safety Checks
DC isolator operation confirmed. AC isolator and consumer unit connections checked. Earth bond continuity verified. Cable entry points and glands inspected for water ingress. Any signs of heat damage, arcing, or loose connections flagged immediately.
Inverter & Battery Health
Inverter physically inspected for fan noise, heat discolouration, and error indicators. Battery units checked for swelling, damage, and cable condition. Cell balance reviewed via inverter interface. Generation performance compared against expected output for your system size and location.
Settings & Configuration Audit
Export limit verified against DNO agreement. Charge and discharge schedules reviewed for your current tariff. Firmware version noted with update recommendation if applicable. Monitoring portal checked and corrected if needed. CT clamp orientation confirmed.

What we check on site
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.
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.
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.
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.
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.
On-site maintenance vs remote health check
Both services assess your system's health — but they cover different ground. Choose the right one for your situation.
Best for: systems not inspected recently, older installations, property sales, peace of mind.
Best for: performance concerns, settings review, systems already physically inspected. See health check →
Annual maintenance visits across Yorkshire & beyond
We carry out on-site annual maintenance visits across a wide coverage area from our Yorkshire base — including Leeds, Bradford, Wakefield, Harrogate, York, Sheffield, Huddersfield, Doncaster, Hull, Barnsley, Scunthorpe, Grimsby, Mansfield, Derby, Nottingham, Manchester, Darlington, and Middlesbrough.

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.
When was your system last inspected?
If it's been more than a year — or if no one has physically checked since installation — a maintenance visit catches the issues that monitoring can't see. From £195, written report included.
