Solar Panel Cleaning Services – UK Wide
We provide professional solar panel cleaning services across the UK, helping asset owners maximise performance, protect equipment, and extend system lifespan. Using advanced SolarCleano robotic cleaners, QLEEN RotaQLEEN motorised brushes, and Chemitek-certified solar cleaning chemicals, we deliver safe, efficient, and cost-effective cleaning for rooftop systems, ground-mounted solar farms, and tracked solar arrays.
Why do solar panels need cleaning?
Immediately after installation, photovoltaic (PV) solar panels operate at peak efficiency. However, over time, environmental factors such as wind-blown dust, airborne particles, bird fouling, pollen, and rainfall residue begin to accumulate on the panel surface. This soiling creates a barrier between the sunlight and the solar cells, reducing the panels’ ability to absorb light and convert it into clean, usable electricity.
Data collected by our team over more than four years of cleaning a wide range of solar installations indicates that systems left uncleaned can suffer efficiency losses of between 20% and 75% over the course of a calendar year, depending on location and environmental conditions. To ensure the highest cleaning standards, all of our SolarCleano robots configured for wet cleaning operate using 100% de-ionised water. This process removes all minerals and impurities found in tap water, delivering a streak-free finish and helping panels stay cleaner for longer — extending performance beyond what standard water cleaning can achieve.
Professional Solar Panel Cleaning Services
Regular solar panel cleaning is one of the most effective ways to maintain energy output and protect long-term investment. Dirt, dust, pollen, bird droppings, and environmental pollution can significantly reduce panel efficiency — often by 5–20% or more depending on location and conditions. Our UK-wide solar cleaning services are designed to remove these contaminants safely and efficiently, restoring panels to optimal operating condition.
We work with a wide range of clients, including commercial building owners, agricultural sites, asset managers, and utility-scale solar operators. Whether your installation is roof-mounted, ground-mounted, or part of a tracked solar array, our team deploys the most appropriate cleaning method for your site, layout, and operational requirements.
Advanced Cleaning Technology
We utilise a combination of industry-leading equipment to deliver consistent, high-quality results:
SolarCleano robotic cleaning systems for large-scale and commercial installations
QLEEN RotaQLEEN motorised brushes for precision cleaning on rooftops, glass, and smaller arrays
Chemitek professional solar cleaning chemicals, used where appropriate to enhance cleaning performance and reduce re-soiling
This approach allows us to tailor the cleaning method to each site — whether that means wet or dry robotic cleaning, pure-water brushing, or chemical-assisted cleaning for stubborn contamination.
Suitable for All Solar Installations
Our cleaning services are suitable for:
Commercial and industrial roof-mounted solar systems
Large-scale ground-mounted solar farms
Tracked solar arrays, including systems with variable tilt and movement
Mixed or complex sites with varying panel heights and layouts
By combining robotic systems with manual and motorised tools, we can safely access difficult areas while maintaining speed and consistency across large installations.
Suitable for All Solar Installations
Regular solar panel cleaning delivers measurable benefits:
Increased energy output and system efficiency
Reduced risk of long-term panel degradation
Improved ROI and payback period
Lower maintenance costs over the system lifetime
Early identification of issues during routine cleaning visits
For many sites, scheduled cleaning forms a key part of an effective operations and maintenance (O&M) strategy.
Site-Specific Cleaning Plans
Every solar installation is different. To ensure we deliver the most effective service, we ask clients to complete a short enquiry form detailing key information about their system — such as installation type, size, access, and location. This allows us to assess the site properly and recommend the most suitable cleaning method before any work is carried out.
