What is Pure Water?

It’s water in its purest form, physically processed to remove the minerals that would otherwise lead to limescale spots and streaks.
Such impurities are referred to as TDS (total dissolved solids) and are measured in ppm (parts per million).

The water is considered 100% demineralised (pure) when TDS is 0 ppm.

How does the cleaning effect work ?

  • Water always tries to keep a balanced mineral content.
  • By filtering the water all minerals are removed. The water takes them back from the dirt of the cleaned surface.
  • When rinsing with water, the dirts runs down.
  • The surface remains streakfree.
  • You only need one cleaning step. The surface cleans by itself without residues.


What has to be cosidered when cleaning solar panels?

  • Avoid large temperature differences between water  and surface.
  • Especially in summer, the modules are very hot.
  • The temperature diffrenece between water and module should not be more than 20°C.


What systems are available for filtering the water?

  • Reverse-Osmosis (RO) and Deionisation (DI).
  • The difference is the frequency of use, the amount of needed water and the investment and maintenace cost.
