Intersolar 2009 photovoltaic fair |
Floorplan Intersoler 2009 | |||
Growth of 7 halls with 76.000 squaremeter to 9 occupied halls with 100.000 squaremeter. |
Cities with solar energy | |||
Imagine entire cities powered by the sun. Already the placards from the parking lot west to the entrannce show the most important of the Intersolar 2009. |
The potential of solar power | |||
Put enough pannels in enough places, and the promise of solar becomes limitless. For this, a technology based on raw material available like sand on the beach in necessary. |
Enough solar power for planet earth | |||
Finally, solar power on the scale the planet has been waiting for. In 7 month brought Applied Materials 5 factories to mass production. |
Masdar photovoltaic | |||
At the Masdar project, they do not order for the future town photovoltaic modules, but photovoltaic factories. Applied materials delivers the production equipment. |
Cheap photovoltaic | |||
The moduls are the 1/4 size from Signet. Signet is top favorite for the roof of my future house. Signet has the production equipment from Applied Materials. |
Combined electric power and heat | |||
2008 had been this combination of photovoltaic and solar collector honored by the German price of handwork companies. |
Combination photovoltaic and solar collector | |||
Roof areas have to be used more efficient. More electric power by cooling the photovoltaic and heat production as an additional benefit. |
Electric scooters for Africa | |||
Photovoltaic and electric scooters for Africa. A theme mentioned by PEGE in alternative US military budget 2007 and oil exit 2008 now shown at the Intersolar. |
Dipl. Ing Samuel D Fan | |||
Shows the range of his home systems. Left a 12 V DC system with 12 Ah battery and 18 Watt photovoltaic, left with 2 100 Ah batteries and 160 Watt PV. |
Mini photovoltaic home system | |||
12 Volt 12 Ah battery and 18 Watt photovoltaic are enough for radio, light, charge the cell phone and a netbook. On the right side 2 12 V sockets. |
Solar home system with 1300 Watt | |||
2 * 80 Watt photovoltaic and 2 * 100 Ah batteries can produce by an inverter up to 1300 Watt 230 Volt AC. This is like to have on a camp ground a 6 A fuse. |
Box photovoltaic home system open | |||
In the box at the bottom 2 100 Ah lead acid batteries and above the inverter. Left below middle a fan to bring the heat from the inverter out of the box. |
1,25 Megawatt inverter | |||
Who has a roof as large as 2 soccer fields needs this a little bit bigger inverter. In the opened part on the right side is a transformer for the medium voltage grid. |
Megawatt electric cable | |||
3 electric rails 10mm x 80mm are coming from the inverter. After this each phase has 2 cables, each 300 mm² to the 20.000 Volt transformator with 1,25 MW power. |
1,25 Megawatt Transformator | |||
This 4,3 tons heavy trnaformator has the task to feed 1,25 MW solar electric power in the medium voltage grid. In the right 3 cables for 20 kV. |
Daylight from the roof to interior room | |||
On the fair is a trailer to show how to bring daylight into a windowless interior room by a light well. |
Interior room illuminated by light from the roof | |||
In the interior room of the trailer comes light only by a light well with 25 cm diameter. |
