| Combined collector
|
| 
|
|
|
From left to right: solar collector, photovoltaic and both in one. The combined colletor has a so good thermal efficiency, that hot water can be produced without heat pump.
|
| Part form an adequate roof
|
| 
|
|
|
An aluminium tin with inlaid pipes similar to a floor heating. The roof delivers heat in the summer. The roof is kept snow free in winter. Above the photovoltaic.
|
| 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.

| 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 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.
|
| 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.
|
| Electric power, heat and climate regulation
|
|
|
Big towns have a some degree Celsius more warm climate than the green surroundings. This has not to be like this, however a mad energy wastefulness costing us much money.
|
| Roof secure for the future
|
|
|
Roofs not producing no electric power an no heat and break down because a littile bit snowfall have nothing to do with a secure future.
