Chemitek’s Solar Wash Protect (SWP) is a 2-in-1 professional-grade solution that not only cleans accumulated organic dirt (bird droppings, pollen, tree sap, grease) from solar modules but also applies a protective antistatic coating to reduce future soiling.
Compatible with manual, robotic and drone-based cleaning systems, SWP is ideal for residential, commercial and utility-scale solar installations.

SWP is a professional solar panel cleaning and protection solution developed to remove organic dirt, dust, and residues from PV modules.
The product not only cleans the surface effectively but also leaves behind an antistatic, protective coating that helps reduce future soiling and water spotting.
It is a biodegradable, pH-neutral formulation, tested and approved for safe use on solar glass, frames, and coatings — reducing water consumption and brushing effort during every clean.
Cleans solar panels effectively
Reduces future soiling and spotting
Protects with an antistatic layer
Improves energy efficiency and yield
Solar Wash Protect is a biodegradable product designed to be as delicate as possible with the components of the solar module (ARC, silicone and aluminium frame).
Chemitek Solar Wash Protect (SWP) must always be diluted with pure or demineralised water before use.
The correct dilution ratio depends on the level of soiling and the cleaning method being used (manual, robotic, or drone).
For best results, apply on cool, dry panels, avoiding strong sunlight.
Suitable for regular cleaning cycles or lightly soiled panels. Removes dust, pollen, and minor organic residue while applying an antistatic coating that helps prevent re-soiling.
Ideal for most UK installations exposed to general pollution, bird droppings, or moderate organic buildup. Ensures deep cleaning while maintaining surface protection and shine.
Recommended for heavily contaminated panels or long-neglected sites. Provides maximum cleaning strength while remaining safe for coatings and seals. Repeat application may be needed in extreme cases.
The product delivers the best results when applied on cool, dry panels — avoid cleaning under direct sunlight.
We recommend using soft to medium bristle brushes to ensure an even clean without scratching the glass.
For manual or robotic cleaning, dilute SWP Concentrate according to soiling level (typically 1:100 to 1:300) and apply evenly using a hand, pump, or battery sprayer.
Spray evenly over the entire surface of the dry panels.
Allow a short dwell time (1–3 minutes) for the formula to loosen dirt and residues.
Brush or agitate to lift contaminants.
Rinse thoroughly with pure or demineralised water.
SWP leaves behind a thin antistatic protective layer that reduces future soiling and water spotting.
For operators using rotary brushes, cleaning robots, or drone systems, SWP can be pre-mixed directly into the cleaning water or dosed automatically via pump.
Mix at a ratio between 1:100 and 1:300 depending on dirt level.
Apply using your regular cleaning equipment, maintaining even water flow across panels.
Allow 1–3 minutes contact time, then rinse with pure water.
Do not allow the solution to dry on the surface.
This method is ideal for large-scale installations where efficiency and consistent coverage are key.
Chemitek is a global leader in the development of innovative solar panel cleaning and maintenance chemicals. Their range is designed to maximise PV system performance while protecting the environment. All products are biodegradable, TÜV-tested, and approved by major solar module manufacturers.
Unlike general-purpose cleaners, Chemitek products are specifically formulated for photovoltaic (PV) glass. They remove soiling effectively without damaging anti-reflective coatings, seals, or frames. Each product targets a specific issue — such as organic soiling, lichen growth, or static dust — and has been tested for compatibility and warranty safety.
Yes. Every Chemitek solution is biodegradable, pH-neutral, and non-toxic, designed for use in sensitive environments including floating PV systems and agricultural installations. Wastewater management guidelines are provided to ensure compliance with local regulations.
SWP is a 2-in-1 cleaner and antistatic protectant for regular maintenance of solar panels, removing dirt, pollen, and organic residue.
LRA, on the other hand, is a specialised treatment for stubborn biological growths such as lichen, moss, and algae. It’s ideal for panels in damp or shaded UK and Irish environments.
Yes. Chemitek holds letters of conformity from leading module manufacturers confirming that its products are warranty-safe when used according to the official instructions. They have been independently tested by TÜV SÜD to ensure full compatibility with solar glass and frames.
Cleaning frequency depends on the local environment. In the UK and Ireland, panels typically benefit from 1–2 cleanings per year using SWP, with additional LRA treatment as needed in high-lichen or coastal areas. ASA 2.0 can extend the interval between cleanings by up to 50%.
Yes — positively. By removing soiling and preventing recontamination, Chemitek products help recover lost yield caused by dirt and biological buildup. Field results show 3–5% performance improvements after cleaning with SWP or LRA, and longer-lasting cleanliness when ASA 2.0 is applied.
Chemitek’s full range — including SWP, LRA, ASA 2.0, and other cleaning agents — is available through their official UK & Ireland distributor, Solar Clean Robotics UK.
