Photovoltaic and heat combined

Cogeneration of electric power and heat from one modul. Optimal utilization of roofs by combined production of electric power and heat on the same area.
Combined collector 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.

  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.

  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 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.

  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.
