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.
| 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. | 
| 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. |
