| 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. | |||
| 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. | |||
| Light well |   | ||
| Light well to bring from the roof of a building daylight fo a windowless interior room. in | |||
