Connecting Homeowners With Reliable and Trusted Solar Panel Cleaners

Solar Assure – Solar Panel Cleaning

Why Choose our Certified Cleaners: Many tradespeople are turning to solar panel cleaning as it becomes more common. The issue is that many tradespeople lack the expertise, equipment and formal requirements to safely and effectively clean your solar panels.

This exposes you to risk of damage, voided warranty and possible injury at your home.

Our certified solar panel cleaners all meet the following standard independently verified by us:

• Verified Insurance (inc cover to property worked upon)
• Warranty safe processes
• Proper Personal Protective Equipment (electrically insulted gloves and boots)
• Verified ID and business check inc CCJ clear
• Thorough and ongoing online reputation and conduct checks

The Solar Assure network of certified cleaners is growing across the entire United Kingdom including England, Wales, Scotland and Northern Ireland.

Our network is presently expanding to ensure all homes have reasonable coverage and a certified cleaner within a viable service distance.

Cleaned Solar Panels

Maximum Energy Yield. Professional cleaning can restore up to 25% of your system’s output. By removing the “invisible” traffic film and salt spray common in the UK, your panels can finally capture every available ray of sunlight.

Accelerated Financial ROI. For homeowners on the Feed-in Tariff (FiT) or Smart Export Guarantee (SEG), more generation means more tax-free income. A professional clean often pays for itself through increased generation in just a few months.

Warranty Compliance. Most leading manufacturers specify that panels must be maintained to keep the performance warranty valid. Using Solar Assure certified methods ensures your investment stays protected under manufacturer terms.

Long-Term System Health. Regular maintenance using de-ionised pure water prevents the buildup of abrasive grit. This keeps the anti-reflective coating intact, ensuring your array continues to perform for its full 25-year lifespan.

Dirty Solar Panels

Permanent Glass Damage. Bird droppings contain oxalic acid, which can permanently etch the glass surface if left to bake in the sun. Once the glass is etched, its ability to transmit light is compromised forever.

Destructive “Hotspots.” Lichen and moss don’t just block light; they create localized areas of high resistance known as Hotspots. These can cause individual solar cells to overheat, leading to catastrophic system failure.

The Invisible Filter. Even if they look “fine” from the ground, panels in the UK quickly build up a sticky layer of pollen, dust, and vehicle emissions. This film acts as a permanent filter, dampening your system’s performance every single day.

Wasted Investment. A dirty system is an underperforming asset. Every day you delay cleaning, you are essentially buying electricity from the grid that your system should be providing for free.

Annual Efficiency Cycle

Solar panels in the UK are subject to a seasonal “sticky” film of pollen, tree sap and traffic emissions.

While rain may rinse off loose dust, it cannot shift the stubborn grime that builds up over 12 months.

An annual professional clean ensures your system enters the peak generation months (Spring and Summer) in optimal condition, preventing year-on-year performance degradation.

Visible Organic Growth

If you can see white or yellow spots (Lichen) or green tufts (Moss) from the ground, your panels are at immediate risk.

These organisms use tiny roots to grip the glass, which can lead to permanent etching and “hotspots” where cells overheat.

Because Lichen is highly resistant to rain, specialist removal is required to protect the structural integrity of the panel surface.

Discrepancies in Generation Data

If you monitor your system via an app or inverter and notice a lower-than-expected yield compared to the same month last year, dirt is the most likely culprit.

Even a thin, uniform layer of dust (which might not look “dirty” from a distance) can act as a filter, reducing the light reaching the silicon cells.

If the data shows a dip, your ROI is actively leaking.

Environmental High-Impact Zones

Homeowners located near busy roads, construction sites, farmland or coastal areas will experience much faster soiling.

Sea salt, bird droppings from local flight paths and agricultural dust create a “crust” that severely hampers performance.

In these environments, we recommend a bi-annual inspection to ensure your investment isn’t being stifled by its surroundings.

1. Comprehensive Safety Assessment

Every project begins with a meticulous pre-clean audit of your solar array. We inspect the panels for existing glass fractures, micro-cracks, or compromised wiring before any water touches the surface. This proactive approach ensures your system’s electrical integrity is fully protected and guarantees that the cleaning process is entirely safe for both our technicians and your property.

2. Specialised Non-Abrasive Access

We prioritise the structural health of your roof and panels by utilizing advanced carbon-fibre reach-and-wash systems. Our technicians never walk on your tiles or apply weight to the solar frames, completely eliminating the risk of cracked slates or internal cell damage. By operating safely from ground level or specialized towers, we maintain total control without ever compromising your home’s integrity.

3. Advanced Pure Water Technology

We use 100% de-ionised pure water to achieve a laboratory-grade finish. While standard tap water contains minerals that leave behind “spotting” and a dulling film, our purified water acts like a magnet for dirt. It lifts stubborn grime and dries to a perfectly clear, streak-free finish, ensuring maximum light transparency and allowing your panels to operate at their absolute peak generation capacity.

4. Environmentally Safe (No Chemicals)

Our process is entirely chemical-free, making it 100% safe for your garden, pets, and local wildlife. Because we avoid harsh detergents and solvents, there is zero risk of degrading the delicate anti-reflective coating on your panels or contaminating your rainwater harvesting systems. It is a sustainable, pH-neutral solution that delivers a superior clean while remaining environmentally responsible.

Pricing Guide

While exact costs vary based on your specific location and the complexity of the project, we believe in clear, upfront guidance. Most residential solar cleaning projects in the UK fall into the following investment brackets:

Estimated Price Brackets

Key Factors That Influence Your Quote

We don’t believe in “hidden fees,” but certain variables will affect the final price provided by your local Solar Assure technician:

• Access & Safety: Most systems can be cleaned from the ground using our carbon-fibre poles. However, if specialized towers or roof-access equipment are required for high or awkward reaches, this will be reflected in the cost.
• Level of Organic Growth: A “standard” film of dust and pollen is quicker to clear than a system heavily encrusted with lichen, moss, or bird “crust.” Heavy organic growth requires more pure water and more mechanical agitation (brushing).
