UK-Based Specialists in Solar Panel Cleaning
APT ICC provides professional solar panel cleaning services across England and Wales, supporting industrial, commercial, and infrastructure clients with the safe and effective cleaning of solar installations. Solar panel cleaning focuses on removing surface contamination that can reduce light transmission and lower energy output over time.
The service is sometimes referred to as photovoltaic (PV) panel cleaning or solar array cleaning. In simple terms, it involves carefully cleaning the surface of solar panels to remove dirt, dust, algae, bird fouling, and other environmental deposits that naturally accumulate when panels are exposed to the elements. Even light soiling can significantly affect performance, particularly on large installations.
APT ICC cleans both ground-mounted solar farms and roof-mounted solar panels on factories, warehouses, and industrial buildings. Each site is assessed in advance to determine the safest and most appropriate cleaning method, taking into account panel type, access requirements, and whether the system remains live during works. Cleaning is carried out in a controlled manner to protect panels, frames, and surrounding roof structures.
Solar panel cleaning is typically used as part of planned maintenance to maintain efficiency and protect long-term asset value. It is especially important in industrial environments where airborne dust, traffic film, or agricultural residue can build up more quickly. Regular cleaning helps ensure systems continue to perform as expected and avoids unnecessary output losses.
With over 35 years of experience working in live industrial and commercial environments, APT ICC is trusted to deliver solar panel cleaning safely and effectively. All works are assessment-led and carried out under strict health, safety, and environmental controls, ensuring minimal disruption while delivering reliable results across England and Wales.
“I would like to express my sincere thanks to APT for the excellent job they carried out at Tai Bach. The project was a much needed one and now that it is completed it has really helped to improve the look of the town. We have received many good comments from the public which is always a good sign.”
Kevin Hiller - Property Surveyor, Neath & Port Talbot Council
“We employed the services of APT to renovate a Grade 2 Listed Building. Under the directive of Cadw we were not allowed to use any wet process or chemicals within the interior of the building. APT used Soda Blasting on sandstone, brick, ceramic glazed tiles, metal work, paintwork on ceilings, coving, woodwork and ornate fixtures.
It was a great achievement to have one system for all the surfaces that needed cleaning and restoring and one that also ticked all the boxes of the environmental and conservation officers. The process saved us both time & money in being able to have just one company on site. We are very grateful to APT for their hard work on this project.”
Tim Luke - Gee Construction
“I would like to thank APT-ICC for their excellent work and assistance on the Barclays Bank project. They delivered the scheme and additional works on time and without issue thanks to Andrew and his team for all your extra effort, long hours and commitment. I look forward to using them on future renovations.”
Graham Lowe - Project Manager, Overbury Plc
“We have been receiving an overwhelming number of positive comments about the war memorial cleaning. Yesterday, during the small ceremony at the Penrallt column on the 1st World War anniversary, many expressed their appreciation for how splendid the memorial looks after the cleaning. We anticipate sharing photos on the internet page later this week. Additionally, we have shared your details with another person who serves as the clerk to two other local councils. Thank you once again for the exceptional work.”
Janice Davies - Gwynedd Council
Dirt, dust, and environmental build-up reduce the amount of light reaching the panels. This lowers energy output and efficiency over time. Regular cleaning helps systems perform as intended.
Even light soiling can cause noticeable performance loss, especially across large arrays. In industrial environments, airborne dust and traffic film can build up quickly. Cleaning helps restore consistent output.
Small, easily accessible systems may be cleaned in-house with care. However, roof-mounted panels, large arrays, or live systems usually require specialist access and methods. Incorrect cleaning can damage panels or reduce lifespan.
Yes, when cleaning is properly planned and controlled. Professional cleaning is often carried out on live systems using suitable equipment and methods. Safety and panel protection are key considerations.
Low-pressure cleaning with appropriate tools and water quality is typically used. Harsh chemicals or abrasive methods should be avoided. The correct approach depends on panel type and site conditions.
This depends on location, surrounding activity, and environmental exposure. Industrial and agricultural areas often need more frequent cleaning. Many sites include panel cleaning as part of planned maintenance.
Yes. Removing build-up reduces hot spots, uneven loading, and long-term surface wear. Clean panels are also easier to inspect for damage or defects.
Yes. In some cases, suitable professional-grade cleaning products can be used safely. APT ICC can advise on appropriate solutions, including those manufactured by APT Commercial Chemicals, which we use across sites in England and Wales.
