As more homeowners across Kent invest in solar panels, keeping them clean has become increasingly important. Dirty panels can lose efficiency over time as dust, traffic film, algae, bird droppings, lichen and other contaminants reduce the amount of sunlight reaching the solar cells.

While it may be tempting to ask your regular window cleaner to give your panels a quick clean, there are several important reasons why using a specialist solar panel cleaning company is the safer and more effective choice.

One of the biggest differences between a professional solar panel cleaning company and a general window cleaner is how the work is carried out.

At Lilypad Exterior Cleaning Ltd, we regularly use professional high-level access towers where required, allowing us to work safely alongside the roof and apply the correct amount of pressure to our specialist solar panel brushes.

Many window cleaning companies clean solar panels from ground level using long water-fed poles. While this can be suitable in some situations, the length and flexibility of the pole can make it difficult to apply consistent pressure to the brush head. This often means stubborn dirt, algae, lichen and bird fouling are not fully removed.

Being positioned closer to the panels allows us to clean every section thoroughly while maintaining complete control over our equipment.

Not all contamination can be removed with pure water alone.

Over time, solar panels can develop stubborn organic growth, traffic film and lichen that require more than a standard rinse. Using unsuitable chemicals can damage protective coatings or even affect manufacturer warranties.

That’s why we use specially formulated soft wash cleaning products that are approved for use on solar panels. These products are designed to safely break down organic contamination while protecting the glass surface and anti-reflective coatings.

Combined with purified water and specialist equipment, this delivers a far more effective clean than water alone where heavier contamination is present.

Insurance is another important consideration that many homeowners overlook.

Solar panels are a significant investment, and any work carried out on or around them should be covered by the appropriate insurance.
Lilypad Exterior Cleaning Ltd is fully insured for professional solar panel cleaning, giving our customers complete peace of mind.

Before hiring anyone to clean your solar panels, it’s worth asking whether their insurance specifically covers this type of work. While many excellent window cleaners provide fantastic window cleaning services, solar panel cleaning is a specialist service and may not always be included within their insurance policy.

Solar panels are designed to last for decades, but like any external surface they require periodic maintenance.

Professional cleaning helps remove:

• Bird droppings
• Dust and pollen
• Traffic film
• Algae
• Lichen
• Moss spores
• Organic staining

Keeping panels clean helps maximise the amount of sunlight reaching the photovoltaic cells while also improving their overall appearance.
