| Mini photovoltaic home system12 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.Light, communication and education as the entrance to reach a higher standard of living.The fossil age increased the difference between poor and rich dramatic. There was never enough fossil energy for the whole mankind. The solar age makes it possible for the poorest to catch up. |
| 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. | |||
| 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 | |||
