Anti-Soiling & Surface Protection Coatings

Keep Panels Cleaner for Longer

Fine dust clings to module glass through static charge and moisture. Chemitek's anti-soiling coatings treat that cause: they are dosed into the cleaning water and applied in the same pass as a normal wash, leaving a thin protective layer on the glass.

Antistatic Solar Armor 2.0 (ASA 2.0) neutralises the static charge that pulls fine dust onto the glass. D-Solar Defendor (DSD) is a hydrophobic coating that makes water bead and run off. Chemitek reports up to 5% more energy than water-only cleaning, about 50% less cleaning water, and at least a year of protection.

Key Benefits

• Applied during a normal clean: no separate coating visit
• New dust lands loosely and comes off more easily at the next clean
• Up to 5% more energy than water-only cleaning (Chemitek)
• About 50% less cleaning water (Chemitek)
• At least 12 months of protection (Chemitek)
• ASA 2.0 carries 17 module-maker letters of conformity

How to Use (Chemitek Datasheets)

• ASA 2.0: dilute 1 kg in 1,000 L of cleaning water, then clean the panels as normal
• DSD: dilute 1 kg in 1,000 L of soft water (reverse osmosis, distilled, or treated with Water Softening Agent)
• Equipment: rotary brushes, robots or tractor-mounted brushes
• First application: the panels must come out fully clean so the coating bonds to bare glass; with a tractor brush, slow down until all soiling is removed
• Manual brushing: we usually recommend Solar Wash Protect instead

Field Evidence

• Morocco, Green Energy Park (peer-reviewed, Heliyon 2023): over nine months, Chemitek products gave cumulative gains over water-only cleaning of 3.2% (SWP), 2.0% (DSD) and 1.9% (IGP)
• Israel, Chemitek case study: modules protected with ASA after cement removal were still clean two weeks later, while unprotected modules had re-soiled
