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. 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. 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. 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. 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-integrated photovoltaic
For what make a roof and integrate a photovoltaic? It is much eaiser, when the roof and the photovoltaikc are together delivered. 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. Crystalline silicon in thin layer
Much less consumption of silicon. Only 2  k instead of some 100 m is the crystalline layer of this new thin layer module of Sharp thick. 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. 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. Airing system of single-family dwellings
On the top left in the picture is the flap of the summer bypass. Thus the chill current of air from an underground buried pipe is not warmed up by the exhaust air. Comfort ventilation system with summer bypass
If it is very warm in summer, the heat recovery is undesirable. This living space airing has already integrated the bypass for the summer activity. Apartment airing with heat recovery
How does a ventilation system with heat recovery function? In the exhibition stand of Aerex had been a very clear explanation for this. Electic power failure in spite of own photovoltaic equipment
Normally a net-coupled photovoltaic equipment switches off immediately if the net has no tension. Protection for electrical engineers maybe just repairing the grid. Inventer in the German Bundestag
A victory for a complete diffferent inverter stategy on the roof of the German Bundestag in Berlin. Modular instead of high voltage. Dashboard of the first inventer
Zurich ETH developed the prototype of the first inventer. Extremely a lot of expenditure for 576 watts of top achievement. Here the dashboard. First inverter for grid  conection
A real museum piece from the year 1984 was to be seen in the exhibition stand of Baden Wurttemberg: the first inverter with one has tested net feed functions. Fire brigade can refuse extinguishing
Who holds jet of water on something what leads up to 1,000 volts of tension? This photovoltaic switches off at 100 degrees and does not endanger the fire brigade. LED Lamps surface lighting
During the day the light comes by the 10% transparent photovoltaic. The energy is stored and provides also at night for lighting. Station with photovoltaic and LED lamps.
Slightly clear photovoltaic on the top, below a surface with LED lamps. Light of the day provides for more lighting and security at night and everything without mains connection. Photovoltaic world record
12,5 ms ² and 1,550 watts with one modul makes the world-biggest photovoltaic possible. The modul is from Ertl lower Austria. WLAN rip of, no thanks!
11.60 EUR for 2 hours. What should somebody do with such an offer on a fair? An offer with time limit to be consumed in one block is senseless. Blimp airship and solar calculations
If one has seen the adaptable photovoltaic foil of Sharp just on a photovoltaic fair and sees all at once a Blimp, one catches of course immediately to calculate. A blimp is no zeppelin
Above the exhibition center circles a Blimp. Blimp are holding the form by the inside pressure. At a zeppelin, however, by a stiff scaffolding. Fair tents in Freiburg
The intersolar fair 2005 was too big for existing 3 fair halls with 12,000 ms ². Not to have to put up tents again it is extended till 2006 by a hall 4 with 4800 ms ². Intersolar fair Freiburg 2005
A biaxial tracked photovoltaic is the landmark of the Intersolar, which greets the visitors at the entrance. Indeed, not correctly turned towards the sun. Sheep wool insulation
Each cubicmeter contains 16 kg sheep wool. Each sheep delivers about 2 kg wool per year. But how does it happen, that wool is nearly not more expensive than other insulation? Hall heating with wood pellets
Minus 9 degree Celsius 10:00am on the parking lot of the fair. To warm such a tent like fair hall, it's better to rent a 800 kW pellets heating. Heat pump demo
This modified home exercise kit is for the illustration of the heat pump. The compressor powered by human muscles takes the coolant. Home exercise kit heat pump
The theory is well known. Higher temperature difference between cold and warm side causes more energy demand for the heat pump.
