Fair report Intersolar Freiburg 2005

Fair report from Intersolar in 2005 in Freiburg. In 3 parts. fair in general, only about Photovoltaikand special part a href=MY_SITE/2005-afrika/index.htm>solar power for Africa.

  During the day the light comes by the 10% transparent photovoltaic. The energy is stored and provides also at night for lighting.

  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.


Electic power failure in spite of own photovoltaic equipment 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.




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. 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. 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. 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. 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. 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. 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. 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.
