Insurance-backed guarantee on our workmanship
A solar array is a twenty-five year asset with electrical components that need periodic attention. Soiling, a failed optimiser or a tripped inverter can quietly cost you a large share of your expected output for months before anyone notices. We run our own servicing and maintenance department rather than outsourcing it.
What solar servicing and maintenance covers
Solar PV servicing covers the visual inspection, electrical testing, cleaning and fault diagnosis needed to keep a system safe and producing the electricity it was designed to generate. It includes checking panel condition and mounting, testing inverter performance and error logs, inspecting isolators, cabling and connections, and confirming the system is generating in line with expectations for its size and orientation. Maintenance is the ongoing programme of these checks; repair and fault finding is the reactive work carried out when generation drops, a fault light appears, or the system stops exporting altogether.
Who needs it
Any homeowner or business with an existing solar PV system benefits from periodic servicing, regardless of how long ago it was installed or who installed it. This includes systems nearing the end of an inverter warranty, systems that have never been serviced since installation, systems showing reduced output on the monitoring app, and commercial arrays where downtime has a direct cost. It also covers households who bought a property with solar already fitted and have no service history or paperwork for the system.
When it's needed
A service is worth booking annually as routine good practice, and sooner if you notice a fall in generation, an error code on the inverter display, a tripped isolator that won't reset, visible panel damage after weather, or an export figure on your smart meter that no longer matches previous years. Systems that are 8–10 years old or older are also worth a health check, since inverters typically carry a 5-year warranty (extendable to 20) and connections can loosen or degrade over time even where nothing has visibly gone wrong.
Why professional servicing matters
Solar PV involves DC voltages, rooftop working and grid-connected electrical systems, so diagnosis and repair need to be carried out by competent, insured engineers rather than guessed at from ground level. A proper service also protects the value of your original investment: undiagnosed faults can silently cut generation for months, and some issues, left unresolved, risk affecting warranty cover on panels, inverters or batteries. Using an MCS certified, NAPIT registered team means the work is carried out to the standards your original installation should have met.

What it costs to wait
What happens when this is left alone
Falling generation goes unnoticed
Most homeowners don't track daily generation closely enough to spot a gradual decline. A failing string, a shaded panel, or a degrading inverter can quietly cut output by 20–30% for months before anyone questions why the electricity bill hasn't dropped as expected.
Small faults become expensive failures
A loose connection, a failing MC4 connector, or an inverter throwing intermittent errors rarely fixes itself. Left unaddressed, these issues can escalate to full inverter failure, arcing at connection points, or isolator damage — all of which cost more to put right than an early diagnostic visit would have done.
No record, no accountability
Systems installed by companies that have since gone out of business, or that were installed without clear commissioning paperwork, leave homeowners with no one to call when something goes wrong. Without a service history, it's also harder to establish whether a fault is covered under a remaining panel, inverter or battery warranty.
Our process
How we deliver the work
- 01
Book a survey or diagnostic visit
Tell us what you've noticed — reduced generation, an error code, a visible fault — or simply that the system has never been serviced. We'll arrange a visit at a convenient time.
- 02
Visual and physical inspection
Our engineers inspect panels, mounting, cabling, isolators and the inverter, checking for damage, corrosion, loose connections and any signs of wear or previous poor workmanship.
- 03
Electrical testing and fault diagnosis
We test string performance, inverter output and error logs, and carry out the electrical checks needed to pin down the cause of any drop in generation or reported fault.
- 04
Written report and quote
You receive a clear explanation of what was found, what it means for your system's performance, and a written quote for any repair, part replacement or further work required.
- 05
Repair, sign-off and ongoing support
Once you approve the work, our in-house team carries out the repair, retests the system, and confirms it's generating correctly, with our workmanship covered by a 2-year insurance-backed guarantee.
Benefits
What this changes for you
One team, whoever installed your system
We service and repair solar PV systems we installed ourselves and systems installed by other companies, so you're not stuck if your original installer is no longer trading or too far away to help.
Protects your original investment
A system generating below its potential is quietly costing you money every day. Servicing identifies and corrects the causes of underperformance so the system delivers the savings it was designed for.
Proper fault diagnosis, not guesswork
Our engineers use inverter data logs and electrical testing to identify the actual cause of a fault rather than replacing parts speculatively, so repairs are targeted and the underlying issue is resolved.
In-house team, no subcontracted handovers
Our servicing and maintenance department is made up of our own directly employed engineers, so the person diagnosing the fault is accountable for the repair and the sign-off.
Guaranteed workmanship
Repair and servicing work carried out by our team is covered by a 2-year workmanship guarantee, insurance-backed via QANW, giving you cover beyond a simple verbal assurance.
Written record for future reference
Every service or repair visit is documented, giving you a paper trail of the condition and performance of your system — useful for warranty claims, insurance purposes, or a future property sale.
In detail
Solar PV Servicing & Maintenance explained properly
Panel-level checks
Servicing includes a visual check of panel surfaces for cracking, delamination, hot spots or debris, and inspection of the mounting system and roof penetrations for movement, corrosion or loose fixings. Panel warranties typically run from 12 to 30 years depending on the manufacturer, and identifying physical damage early can be relevant to a warranty claim.
Inverter diagnostics
The inverter is usually the first place a fault shows up, whether as an error code, a shutdown, or a drop in reported output. Inverters typically carry a 5-year manufacturer warranty, extendable to 20 years, and our engineers can interrogate the inverter's logs to identify string-level faults, isolation faults, communication errors or component failure.
Battery storage servicing
Where a system includes battery storage, servicing extends to checking battery health, charge/discharge cycling, communication with the inverter, and any error reporting from the battery management system. Batteries typically carry a 10-year warranty, and periodic checks help confirm the battery is charging, discharging and reporting correctly.
Electrical safety and compliance
Every servicing visit includes checks of isolators, consumer unit connections, earthing and cabling condition, in line with Part P and the electrical safety standards expected of NAPIT registered work. This is particularly important on older systems or those installed before current best practice was established.
Residential and commercial servicing
We service domestic rooftop arrays and larger commercial and public sector installations. Commercial servicing is scheduled to minimise disruption to site operations, with reporting suited to facilities and estates teams. We cover Lancashire, Merseyside, Cheshire and Greater Manchester, including Preston, Ormskirk, Southport, Liverpool, Warrington, Chester, Wigan and Bolton.
Common questions
Questions about solar pv servicing & maintenance
Do you service solar systems you didn't install?
Yes. Our in-house servicing and maintenance team inspects, diagnoses and repairs solar PV systems regardless of who originally installed them, including systems where the original installer is no longer trading.
How do I know if my solar panels need servicing?
Signs include reduced generation on your monitoring app, an error code or warning light on the inverter, an isolator that won't reset, visible panel or mounting damage, or simply never having had a service since installation.
How often should solar PV be serviced?
An annual check is good practice, though systems that are 8–10 years old or showing any signs of reduced performance are worth inspecting sooner, particularly as inverters and connections age.
Can you fix a solar inverter fault?
Yes. Our engineers can diagnose inverter faults using error logs and electrical testing, and carry out repairs or replacements where needed, working within the inverter's applicable warranty terms where relevant.
What does a solar panel service include?
A service typically covers a visual inspection of panels and mounting, electrical testing of strings and connections, inverter diagnostics and error log review, and a check of isolators, cabling and earthing, followed by a written report.
My battery storage isn't charging properly — can you help?
Yes, our servicing covers battery storage as well as panels and inverters, including checking charge and discharge behaviour, communication with the inverter, and any battery management system fault codes.
Is servicing covered by my original warranty?
Panel, inverter and battery warranties are provided by the manufacturer and vary in what they cover. We can inspect your system and advise whether a fault is likely to fall within an existing manufacturer warranty.
Which areas do you cover for servicing and repairs?
We carry out solar PV servicing, fault finding and repairs across Lancashire, Merseyside, Cheshire and Greater Manchester, including Preston, Ormskirk, Southport, Liverpool, Warrington, Chester, Wigan and Bolton.
