Positioning of SolarVenti® Professional Units
  1. SolarVenti® Professional is designed for roofs (or ground) with little or no slope.
  2. SolarVenti® Professional is optimally installed facing as close to due south as possible.
  3. A deviation of up to 45 degrees from due south is possible, by simply increasing the area of solar collectors.
  4. At the design stage, you will need to take into account the roof hoods, roof windows and other technical equipment on the roof.

The professional model has been tested by the Fraunhofer Institute in Germany and approved for international Solar Keymark.
SolarVenti® participated in the German (LUKO project) developing the new EN norms.


Normally, it is not necessary to clean the surface of the collector. It can be washed down with water and mild soap if necessary (do not use solvents).


The filter is self-cleaning and requires a minimum of maintenance.

Expected lifetime

Minimum 15 years.
