  Photovoltaic or solar collector


Best of all 100% of the roof surface with photovoltaik and 100% with Sonenkollektoren. This goes by a new technology which unites both functions in the same surface perfectly.

Combined modul photovoltaic solar collector Combined modul photovoltaic solar collector
Looks like a photovoltaic, delivers more electric power than a normal photovoltaic, because this modul delivers also heat at the same time and works so cooler.


Photovoltaic modul with water cooling Photovoltaic modul with water cooling
The photovoltaic has 2 connections for cooling water. Warm with the warmth the swimming pool or the earth collector of the heat pump based heating system.


Backside of a combined photovoltaic modul Backside of a combined photovoltaic modul
Horizontal the common cooling pipe, vertically the capillar pipes for the cooling of the photovoltaic cells. Every degree Celsius cooling brings 0,48% more power.


Heat pump for warm water and heating Heat pump for warm water and heating
Compact in one unit with the buffer storage, the system manages the warmth from the photovoltic moudules, heating and cooling of the earth collector.
