12 Grid Connected PV Power: Navarra, Spain. Total power 1.2 MW, 280 tracker units with BP-Saturn modules, 120 trackers with modules from other suppliers. Tracking along azimuth axis, module tilt 45, commissioning Source: EU PV Project Synopsis,

13 Global Photovoltaic Market (2005) Market volume PV modules (power) 1,800 MW Price per Watt (system) 5.0 Market volume PV systems (turnover) 9,000 Mio. Growth of market annually more than 40 % Price reduction - 5 %/year Market volume PV industry today is equal to market volume of semiconductor industry in the late 1970-ies -13-

14 Electricity from solar (PV) cells is today not competitive with coal / oil / nuclear power, but: We see a rapid (supersonic) growth of the PV industry Why? -14-

15 PV has become a symbol for an inexhaustible, clean and sustainable energy for the future Cost reductions are to be expected for the future. This will open a virtually infinite energy resource for grid connected electricity supply Today, off-grid electricity markets are developing which promise large markets with a stable growth for a large high technology industry -15-

16 Governments in Japan in Germany in some of the states of the USA in almost all the states of the European Union have taken measures to help the PV industry to grow. -16-

17 Support of Renewable Energies is an important part of the German Energy Policy in view of the threats to society through global warming finite resources (+ increasing consumption = rising prices) (political) insecurity of supply, high volatility of prices continued use of nuclear energy -17-

18 Policy measures in Germany support production of renewable energy technologies and consumption of energy from renewable sources. Research and Technology Development (66 Mio Euro in 2004 from the Federal Ministry for the Environment, Nature Conversation and Nuclear Safety (BMU), 1/3 of the total sum is for photovoltaics) The Renewable Energy Law (EEG, April 2004) (Regulation of tariffs for electricity produced from renewable resources: wind, small hydropower, biomass, photovoltaics) -18-

19 The German Renewable Energy Law (EEG) Regulations for electricity from solar (photovoltaic) cells: Electric power utilities must pay Euro/kWh (2006) for electricity from photovoltaic generators, which is fed into the electricity grid (feed in tariff). The contracts between producers and utilities run for 20 years The feed in tariff for new contracts is reduced every year by 5 % (0.492 /kwh in 2007, /kwh in 2008 etc.) No tax money is spent, the electricity utilities redistribute the extra costs to all other electricity consumers. -19-
