Professional servicing to keep your solar system generating at maximum efficiency — protecting your investment for decades to come.
Solar panels are often described as a "fit and forget" technology, and whilst they are certainly low-maintenance compared to many home appliances, they are not entirely maintenance-free. A well-maintained solar PV system in Yorkshire can generate up to 25% more electricity over its lifetime than a neglected one — meaning regular servicing pays for itself many times over.
Here in West Yorkshire, our weather brings its own challenges. Panels accumulate bird droppings, moss, lichen, traffic pollution and general grime that reduces the amount of sunlight reaching the cells. Damp winters can allow water ingress into junction boxes if seals have degraded. Gusty Pennine winds can loosen mounting brackets and shift panels over time.
Leeds Solar's comprehensive annual maintenance service covers everything from physical cleaning and visual inspection to full electrical testing and performance analysis. We provide you with a detailed health report so you always know exactly how your system is performing and whether any action is required.
Our engineers are MCS-accredited, fully insured and carry all the specialist equipment needed to safely access your roof and test your system properly. We service all makes and models of solar panel, inverter and battery storage system across Leeds, Bradford, Harrogate, Wakefield and throughout West and North Yorkshire.
Our thorough maintenance visit covers every aspect of your solar PV system.
Professional soft-wash cleaning using purified, deionised water and specialist equipment. No harsh chemicals — safe for your panels and the environment. Removes bird droppings, moss, lichen, dust and traffic film.
Close inspection of all panels for micro-cracks, delamination, discolouration or damage. We check mounting hardware, rails, brackets and fixings for corrosion, looseness or structural issues.
Full electrical safety inspection including insulation resistance testing, earth bonding checks, DC string testing, and verification that all isolators, fuses and circuit breakers are functioning correctly.
We interrogate your inverter's data logs to identify any fault codes, efficiency losses or communication errors. Firmware is checked and updated where available. We verify AC output quality and grid connection parameters.
Inspection of all roof-level junction boxes, MC4 connectors and DC cabling runs for UV degradation, rodent damage or water ingress. We re-seal any weatherproofing that has deteriorated.
A written health report detailing current performance versus expected output, any findings from our inspection, recommended actions and a performance forecast for the coming year.
We recommend a full annual maintenance service for all residential solar PV systems. This keeps your MCS installation warranty valid, ensures compliance with your inverter manufacturer's warranty conditions, and gives you peace of mind that your system is generating safely and efficiently.
For commercial systems — particularly those on warehouses, factories or farm buildings — we recommend a bi-annual service schedule due to the higher value of the installation and the greater exposure to dust, pollution and bird activity that commercial roof environments typically experience.
Additionally, we'd recommend booking an out-of-cycle inspection if:
Our maintenance contracts offer the best value — sign up for an annual or multi-year plan and you'll receive priority booking, discounted callout rates and proactive reminders before your service is due.

Technically, yes — if your panels are at ground level or on a very low-pitched roof that can be safely accessed without specialist equipment. However, for the vast majority of UK homes where panels are installed on sloping roofs, we strongly advise against DIY cleaning.
The risks include falls from height, voiding your roof or panel warranty by using incorrect cleaning methods or products, and potentially causing electrical faults by allowing water near junction boxes or connectors. Tap water contains minerals that leave deposits when it dries, which can actually reduce panel efficiency further — professional cleaning uses purified, deionised water to avoid this problem.
The electrical elements of a solar PV system — testing, inverter diagnostics and junction box work — should always be carried out by a qualified electrician or MCS-accredited engineer. Working on DC solar circuits carries significant risks if you don't have the right training and equipment.
Our engineers are fully trained in working at height, carry appropriate public liability insurance, and use commercial-grade purified water cleaning systems. Booking a professional service is safer, more thorough and better value in the long run.
If you notice any of these warning signs, don't wait for your annual service — contact Leeds Solar immediately on 0330 223 7664 and we'll arrange a prompt inspection.
Regular professional maintenance actually protects your warranty. Most panel and inverter manufacturers require evidence of proper maintenance to honour warranty claims. Neglecting maintenance — particularly allowing moss or lichen to grow on panels — can void your product warranty. We provide a written service report after every visit that serves as your maintenance record.
A typical residential service takes between 2 and 4 hours depending on system size, roof complexity and the condition of the panels. Commercial services are scheduled on a half-day or full-day basis. We'll give you a specific time estimate when you book.
You need to be home at the start of the appointment so we can access your inverter and consumer unit indoors. Once we have what we need, many customers prefer to carry on with their day — our engineers are professional, DBS-checked and will let you know when the outdoor work is complete.
Yes, there will be a short period — typically under an hour — when your system is isolated for safety during electrical testing. We aim to schedule this during periods of low irradiance where possible, and the generation lost during this time is minimal compared to the long-term efficiency improvements the service delivers.
Absolutely. We service all brands and installations, regardless of who originally fitted your system. We work with all major panel brands (JA Solar, REC, Sunpower, LG, Trina and others) and inverter manufacturers (SolarEdge, Fronius, SMA, Huawei, GivEnergy). Our engineers carry comprehensive test equipment suitable for all systems.
Keep your system generating at peak performance. Annual servicing from just £99.
