Roof renovation for big flat roofs

Photovoltaic
	Different view points about photovoltaic from our different technical magazines as wide outstretched information about electric power from light.

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.

Photovoltaic roof integration
	Reduce costs by photovoltaic roof integration instead of making the roof and all the photovoltaic seperat with much more work time.

Photovoltaik fair Intersolar 2005 in Freiburg

Fair report from Intersolar in 2005 in Freiburg. In 3 parts. fair in general, only about photovoltaicand special part solar energie for Africa.

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.

Transparent photovoltaic
The connecting leads are hidden in the metal frame. The photovoltaic cells generate energie from light of both sides. So, this module is also called Janus.

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.

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.

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.
