FAQ
Why do solar panels need cleaning?
Over time, dirt, dust, bird droppings, lichen, and pollution build up on the surface of solar panels, blocking sunlight and reducing energy output. Regular cleaning keeps your panels performing at maximum efficiency.
How often should I have my solar panels cleaned?
For commercial or agricultural sites, we recommend every 6 months. For domestic systems, once a year is usually sufficient, though frequency may increase in dusty or coastal environments.
How much energy efficiency can I gain from cleaning?
Cleaning can improve output by up to 25%, depending on how dirty the panels are and local environmental conditions.
Do you use any chemicals or detergents?
We use pure deionised water for a spot-free finish, along with Chemitek Solar Wash Protect for professional protection against future soiling. These products are non-abrasive, biodegradable, and safe for all PV surfaces.
Can rain clean my panels for me?
No, rain simply moves dirt around. It’s similar to leaving your car outside in the rain, it doesn’t make it clean.
How do you clean panels safely on roofs?
We use professional access equipment including tracked MEWPs, roof-safe robots (SolarCleano F1), and approved fall-arrest systems to ensure full compliance with UK Work at Height Regulations.
Do you provide reports or photos after cleaning?
Yes, we provide full before and after photos and a report, including panel condition notes and optional performance analysis for insurance or maintenance records.
Can you clean panels on large commercial sites?
Absolutely. We specialise in industrial and commercial solar installations such as warehouses, factories, and farms. Our equipment allows us to cover thousands of panels efficiently and safely.
Will cleaning void my manufacturer’s warranty?
No. In fact, most warranties require regular maintenance to remain valid. We follow manufacturer-approved methods for safe, compliant cleaning.
What areas do you cover?
We cover Norfolk, Suffolk, Cambridgeshire, Lincolnshire, Bedfordshire, and across the UK for larger contracts.
Do you clean ground-mounted systems?
Yes, we’re fully equipped for both roof-mounted and ground-mounted solar arrays, including solar carports and tracked systems.
Do you offer bird proofing or maintenance services?
Yes, we offer gutter cleaning as standard with every Solar panel clean. Bird-proofing and high-level maintenance, providing a complete service package for solar asset owners.
Is your service insured and compliant?
Yes, we are fully insured, trained, and compliant with HSE and Work at Height regulations, providing Risk Assessments and Method Statements (RAMS) for every job.
Can I book a regular maintenance schedule?
Yes, we can set up scheduled cleanings throughout the year to ensure your panels stay efficient all year round.
