Photovoltaic - Electric power direct from light | |||
Even a far north situated industrial nation like Germany could produce a big part of the needed energy by the roofs of the houses. Photovoltaic has much potential. |
Photovoltaik fair Intersolar 2005 in Freiburg |
Double-sided photovoltaic half transparent: Janus | |||
This on both sides active photovoltaic offers new creation elements for the architecture. Maybe a garden fence or the balustrade for a patio. |
Crystalline silicon in thin layer | |||
Much less consumption of silicon. Only 2 µ k instead of some 100 µm is the crystalline layer of this new thin layer module of Sharp thick. |
Fashion color black: new photovoltaic with more achievement | |||
With an increase in output of the crystalline silicon cells also there came a color change. Instead of up to now blue gleaming, present the new cells in deep black. |
Roof-integrated photovoltaic | |||
For what make a roof and integrate a photovoltaic? It is much eaiser, when the roof and the photovoltaikc are together delivered. |
Sandwich roof with heat insulation and photovoltaic | |||
Cross section by a ready roof element: Amorphous photovoltaic from Uni-Solar. Under it in 3 different strengths deliverable a foamed heat insulation. |
Roof: Photovoltaic roof underside | |||
In the underside of a ready roof element are the energy connections of the photovoltaic. Today with this new technology one would produce many large photovoltaic roofs more cheap. |
Roof renovation for big flat roofs | |||
1 m wide and up to 24 ms long are such ready roof elements in mono sandwich construction method. And the generated energy pays off the renovation completely by itself. |
Round standing seam roof with photovoltaic | |||
The photovoltaic is already provided on the roof elements. Quick assembly of the finished part roofs allow a very inexpensive roof as well as favorable solar energie. |
Progress with amorphous silicon cells | |||
The first modules of this size had only 10 watts till 1996. Then in 1997 I could test a 12 watts module. Now the technic has arrived at 18 watts. |
