Water Softening Agent

Water Softening Agent

ChemiTek's Water Softening Agent (WSA) is a specially formulated solution designed to soften hard and very hard water, preventing mineral buildup on the windows or solar panels’ surface.

WSA works by capturing mineral ions such as calcium and magnesium. When added directly to a water tank, it acts within about 20 minutes. For setups without a water tank, real-time softening with a dosing pump and dynamic mixer (e.g., Dosatron) allows water to be softened directly from the tap. WSA can be used in conjunction with all other cleaning agents, including Drone Solar Cleaning Agent (DSA) or Drone Glass Cleaning Agent (DGA), for maximum effectiveness.

BENEFITS OF USING WATER SOFTENING AGENT (WSA)

By using our Water Softener for window- or solar panel cleaning, O&M teams and asset owners can:

  • Save Time and Money: treating water with WSA simplifies water logistics, reducing water shipping costs or avoiding the need for an onsite demineralization system;

  • Improve Energy Efficiency: mineral buildup can significantly reduce the energy output of your solar panels and speed up resoiling. WSA helps keep your panels operating at their maximum performance, providing a more consistent energy output;

  • Extend Panel Lifespan: regular cleaning with WSA helps protect your solar panels from damage caused by mineral buildup, extending their lifespan and ensuring that they continue to perform at their best.

Certified for solar panels by independent laboratories – tested by ÉMI-TÜV Sud.

WSA has been proven safe for all window and panel components (e.g., aluminium frame, anti-reflective coating, and silicone seals) and does not interfere with light transmission. It is suitable for all types of installations, including floating PV (FPV) systems.

FAQ

What kind of dirt can be cleaned with WSA?

WSA is not a cleaning product. It is a softener for hard and very hard water. It is biodegradable and reduces water hardness by capturing mineral ions, preventing spots and stains caused by mineral deposits (e.g., calcium).

Why is it necessary to treat the water before cleaning?

Tap water is almost always unsuitable for cleaning windows or solar modules. The presence of minerals will, after drying, form limescale/stain deposits on your glass. On solar panels this will decrease energy production or even damage the panel due to the creation of hotspots. On windows you won't get a spotless finish when using tap water. Therefore, one of the most important things to consider when cleaning your windows or solar panels, apart from the product you will use to remove the soiling, is the type of water used.

What is HARD water?

Hard waters are those with a high concentration of salts and minerals, mainly cations of calcium and magnesium, or cations of other metals, such as barium, iron, manganese, strontium and zinc. The hardness of water can differ geographically, i.e. it will depend on the geological nature of the place the water passes through and with which it comes into contact. Hard water is associated with areas where the rocks are of a calcareous nature. Waters from limestone areas are harder than waters from granitic areas (waters from granitic areas are typically softer).

Why is it important to use a specific type of water to clean solar panels?

The type of water used in the cleaning and maintenance of solar panels is one of the fundamental steps for correct cleaning. The use of hard water or water with a high content of organic matter (such as water from rivers and lakes) is not recommended for cleaning solar panels. It is recommended to use water with the least possible amount of impurities (the least possible amount of minerals and organic matter), with a neutral pH, non-abrasive to the panel materials.

What type of water is recommended to clean solar panels or windows?

The best water for cleaning solar panels is demineralized water obtained through mechanical or chemical softening processes. Distilled water is also a good option for cleaning panels. Unlike what most think, Reverse Osmosis is not the only way to clean solar panels. RO is recommended for cleaning windows though.

What is the dilution ratio of WSA?

Recommended Dilution Specifications according to Manufacturer (ChemiTek):

  • For soft water, use a dilution of 1:3500 (0,3L per 1000L);
  • For medium water, use a dilution of 1:2500 (0,4L per 1000L);
  • For hard water use a 1:1500 dilution (0,7L per 1000L);
  • For very hard water use a 1:1000 dilution (1L per 1000L).

Note: the dilution might vary according to the expected results.

How long does it take for WSA to act?

The WSA treatment has an action time of about 20 minutes when added directly in the water tank.

If your setup does not include a tank, the real time softening setup is the best for you. This setup includes a dosing pump and dynamic mixer. You can find more information here.

Can i apply other products from Chemitek when using WSA?

Yes, the WSA solution is compatible with other products of Chemitek’s solar range.

Approved by PV Manufacturers

Water Softening Agent has letters of conformity from the top PV manufacturers:

  • Longi
  • JA Solar
  • Runergy

WSA is specifically designed to capture the mineral ions present in hard water, preventing the formation of hard water spots and stains after cleaning. WSA ensures a spotless finish without affecting the windows, panels or the water environment.
