Fair report from the Intersolar 2009. It is possible to built up solar energy as fast as the production of crude oil and natural gas decreases.
| 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.

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.

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.
