D-Solar Defendor
Hydrophobic coating for solar panels: improve self-cleaning properties in humid, rainy and/or snowy environments
D-Solar Defendor (DSD) is a high-performance coating designed specifically for solar panels. It combines the hydrophobic properties with the antiadherent properties, reducing the soiling’s adhesion to the modules and keeping your solar panels cleaner between cleanings by improving the self-cleaning properties on wet environments. Its properties also make the next cleaning easier and reduce light reflection on rainy days by quickly removing the water from the surface.

Certified for solar panels by TÜV Sud
The international laboratory TÜV Sud, recognized by their services of certification of solar panels, certified the DSD as safe for solar panels. This certification assures that the use of the DSD does not damage the panel’s components (e.g., aluminum frame, anti-reflective coating and silicone seals) and does not interfere with the light transmission.
Approved by PV manufacturers
The D-Solar Defendor has letters of conformity from the manufacturers:
- Longi
- JA Solar
- Trina
EASY+ TECHNOLOGY FOR THE SIMPLEST APPLICATION PROCEDURE ON THE MARKET
The hydrophobic coating DSD was designed to be applied with a robot (e.g., Sun-X, Solarcleano, Robsys or Hycleaner) or a brush on tractor (e.g., Sunbrush or SCM) by just mixing it in the cleaning water and cleaning as you would normally would with just water.
A range of benefits ...
Improved energy production: D-Solar Defendor's hydrophobic and antiadherent properties improve the cleaning effect from the rain, increasing energy output.
Long-lasting Protection: this hydrophobic coating helps to maintain the cleanliness and durability of your solar panels, extending their lifespan and reducing maintenance costs. The coating lasts a minimum of 1 year and can be reapplied without having to remove the previous layer.
Fully tested for solar by ÉMI-TÜV SÜD as safe for PV modules.
Environmentally Friendly: D-Solar Defendor’s water based formula is eco-friendly and safe for use on all types of solar panels.

FAQs
D-Solar Defendor gives your solar panels a hydrophobic coating which repels water and soiling from your panel, reducing dirt adhesion to your panel, water consumption, and cleaning time in subsequent washings, and thereby increasing energy production by up to 5%.
The D-Solar Defendor was designed to be applied with a robot (e.g., Sun-X, Solarcleano, Robsys or Hycleaner) or a brush on tractor (e.g., Sunbrush or SCM).
Yes, you should use de-ionized water to dilute your D-Solar Defendor.
You can use our treatment for hard and very hard water Water Softening Agent to make your water softer in order to dilute the DSD.
Yes, this solution was developed precisely for application in extreme climates, that is very rainy or humid climates.
ASA 2.0 can be applied in all kinds of climates and provides an antistatic coating; D-Solar Defendor is for rainy and/or snowy climates and provides an hydrophobic coating. The D-Solar Defendor requires demineralized water for the dilution, while the ASA 2.0 does not require it.
The surface of photovoltaic solar panels must be clean to ensure full operation and maximum performance. Any kind of soiling that may be on the surface of the solar module, be it dust, pollen, tree sap, bird droppings, sand, salt crystals, etc., will reduce the light transmission, i.e. reduce the amount of sunlight reaching the solar module cells, and thus the panel will produce less energy.
See here our contaminant removal agents.
To the naked eye the panels may appear clean, however there will be soiling accumulated, even if it is just the air pollution itself. A simple test to see if your panel is in need of cleaning is to wipe the surface of the panel with a white cloth or cotton pad before the actual cleaning.
According to recent studies, when a solar panel is very dirty it can lose up to 50% of its performance compared to a clean solar panel. However, the Worldwide average energy loss due to soiling is 3 to 5%.
In fact, rain or wind will not keep the panels fully clean. Wind will carry particles that will settle on the panel and rainwater is not enough to remove any incrusted soiling such as bird droppings or pollen. Rainwater can even lead to the appearance of hotspots by accumulating the soiling on the bottom frame of the panels.
In order for the warranty on your solar panel to remain valid, you should use solar panel cleaners that meet the manufacturers' requirements, such as ChemiTek's CRA, LRA, WSA and SWP.
However, as a rule, products with neutral pH that are tested by international laboratories and that are approved by the solar panel manufacturers themselves as they rule out any negative effect of their use on washing solar panels.
Yes, the antistatic and hydrophobic coatings from ChemiTek were developed having in mind the need to reduce cleaning time, maintenance costs and water usage.
