  • Solar energy is the largest energy resource on Earth – and is inexhaustible. Everyday, the sun provides 15 thousands time more energy than all fossil fuels we consume
  • International Space Station ISS, 1. Ausbaustufe: 62 kW (+ 16 kW) ‏ , Si-Zellen,  = 14,5 %
  • 1. Installed PV capacities show a steep growth curve. 2. PV is one of the fastest growing renewable energy technologies today and is projected to play a major role in global electricity production in the future. 3. Driven by attractive policy incentives (e.g. feed-in tariffs and tax breaks), the global installed PV capacity has multiplied by a factor of 37 in ten years from 1.8 GW in 2000 to 67.4 GW at the end of 2011, a growth rate of 44% per year 4. New capacity installed in 2011 was 27.7 GW, two-thirds more than the new capacity added in 2010
  • Despite the rapid growth of the PV market, less than 0.2% of global electricity production is generated by PV
  • Solar power on the path to becoming a key pillar of sustainable energy supply in Germany
  • During only 4 days in power cut, 90 enterprises lost 90 million USD. That is a huge money !
