| Intersolar fair 2005 in Freiburg |
| 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. | |||
| 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. | |||
| 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. | |||
| 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. | |||
| 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. | |||
| 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. | |||
| 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. | |||
| 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. | |||
| 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. | |||
| 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. | |||
| 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. | |||
