Cost-efficient and environmentally friendly solar panel cleaning technology

The TF-4 cleaning technology offers an efficient solution for PV module solar panel systems as well as for concentrated solar power systems too.

One of the reasons for the high effectiveness of the TF-4 technology is the fact that the cleaning process is divided into two phases, both of which are highly efficient.


The first phase involves a dry mechanical cleaning during which dust, sand and other easily removable contamination are eliminated.

In the second phase the surface is wet wiped removing any other remaining contamination.


The special micro-fiber textile material ensures the best cleaning results. To make it wet and therefore more efficient we use an environmentally friendly additive. The rolled textile is moved in a way that the surface is always cleaned with the clean part of the textile.


One of the great advantages of the TF-4 technology is the fact that it uses very little water. Depending on the amount of the contamination on the PV modules 1 liter of water is sufficient for cleaning up to 12-14 square meters of solar panel. The water usage of conventional cleaning technologies is 50-60 times more that ours. Another advantage is that the micro-fiber material collecting the contamination can be washed and reused multiple times.
