Quickly removes water from the solar panel, promoting its self-cleaning.
D-Solar Defendor is a concentrated product that when diluted in water creates a hydrophobic (water repellent) coating for solar panels, which also provides antistatic properties to the solar glass, thus reducing dust adhesion, keeping it cleaner between cleanings, increasing the efficiency of the next wash as well as increasing irradiance on rainy days, producing up to 5% more energy.
The hydrophobic coating on the D-Solar Defendor is designed to be applied in specific climates (sometimes extreme rain, sometimes extreme drought) with a robot or brush tractor, and on solar panels that are not heavily soiled.
The coating lasts up to 1 year, however ChemiTek recommends applying the product twice a year when there is more soiling.
This product is fully tested and certified by the international laboratory TÜV Sud.

D-Solar Defendor gives your solar panels a hydrophobic coating which repels water and dirt 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 is designed to be applied with a robot or a tractor brush.
Yes, you should use de-ionized water, that is distilled water, with pure solvents, and free of ions, to dilute your D-Solar Defendor solution and apply it to your panels.
Yes, this solution was developed precisely for application in extreme climates, that is very rainy or very hot and dry climates.
ASA can be applied in all kinds of climates and provides an antistatic coating; D-Solar is for extreme climates (with a lot of rain or very dry) and provides a hydrophobic coating, so it will take longer to remove and requires a specific water for dilution.
The surface of photovoltaic solar panels must be clean in order to ensure full operation and maximum efficiency. Any kind of dirt 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 footprint of the sun's rays, i.e. reduce the amount of sunlight reaching the solar module cells, and thus the panel will produce less power.
To the naked eye the panels may appear clean, however there will be dirt 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 efficiency compared to a clean solar panel. However, an energy loss of 10 to 15% can be observed in panels with some dirt.
In fact, rain, snow, or wind alone does not wash the solar panels, because wind carries particles, snow because it blocks sunlight, and rainwater because it is slightly acidic and, when it dries, leaves spots that quickly attract dirt again, thus making the solar system less efficient.
A simple way to illustrate why the weather alone does not wash out the solar panels is to look at the windshield of your car. If you leave your windshield dirty for a long time, you will lose visibility due to accumulated dirt, but thanks to the cleaner that you apply and the windshield wiper, you can wash the glass and regain visibility in no time!
In this way, the solar panels are like the windshields of your car, except that they do not have readily available liquid for washing the solar panels associated with the windshield wiper.
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 D-Solar Defendor.
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.
Solar Wash Protect as a cleaning product, in addition to efficiently removing different types of dirt, does not allow dirt to adhere as easily to the surface of the solar panel, due to its antistatic property. Therefore, by preventing the panels from getting dirty more quickly, it prevents a rapid decrease in the solar panel's power generation. Since dirt does not stick to the surface of the panel, in subsequent cleanings you will notice an easier and faster removal of dirt.
