1 RENEWABLE ENERGY FOR EUROPE - RESEARCH IN ACTION PV solar electricity in Europe – competing with Japan, USA and SEA ( China, Taiwan, Korea, India, etc.) Dr. Winfried Hoffmann SCHOTT Solar GmbH, Management Board Member of the Board of the German Solar Industry Association (BSi), the European PV Industry Association (EPIA) and the Scientific Boards of FhG-ISE and ISFH

2 RENEWABLE ENERGY FOR EUROPE - RESEARCH IN ACTION Ingredients for successful competition within a given world economy region ($, €, ¥)  Big local market size  strong local industrial production $ € ¥ 2

3 RENEWABLE ENERGY FOR EUROPE - RESEARCH IN ACTION  the creation of a strong local industry production employment (primary and secondary) taxes  the creation of a corresponding big local market market support programs boundary conditions for "free" markets Development of a new future industry needs 3

4 RENEWABLE ENERGY FOR EUROPE - RESEARCH IN ACTION  Global competitiveness strong R&D quick transfer via piloting into production  Economy of scale purchase (@2/3 material cost !) cost learning curve for individual companies For an individual company and a given technology it is important: 4

7 RENEWABLE ENERGY FOR EUROPE - RESEARCH IN ACTION Competitiveness between electricity generating cost for PV and utility prices Source: RWE Energie AG and RSS GmbH Photovoltaics Utility peak power Bulk power market support programs necessary: 7 Europe well in balance with other regions !

8 RENEWABLE ENERGY FOR EUROPE - RESEARCH IN ACTION  Cost and price decrease for technology driven PV solar electricity systems (… -5% (+) p.a.) experience curves and technology roadmap  Cost and price increase for conventional electricity (… +1% … 3% (+) p.a.) fuel price increase internalization of external cost (CO2, … ) price differentiation of peak and bulk electricity in truly liberalized markets  Degree of correlation between times of peak power demand (high price) and delivery of PV produced electricity Point of time for competitiveness of grid- connected PV solar electricity without support 8 Europe together in the same boat with other regions!

11 RENEWABLE ENERGY FOR EUROPE - RESEARCH IN ACTION Comparison of the future market development in Europe and Japan Yearly installations mainly Germany Cumulative installations mainly Germany Yearly installations Japan Cumulative installations Japan Additional EU-installations e.g. EU-wide feed-in tariff program (not contained in accumulated curve) must be revised towards 5 GW cumulative and 1300 MW in 2010 in Europe ! 11

12 RENEWABLE ENERGY FOR EUROPE - RESEARCH IN ACTION Market-Pull in Japan for PV Solar Electricity Disadvantage of strong € !

13 RENEWABLE ENERGY FOR EUROPE - RESEARCH IN ACTION  Worldwide free trade  not enhanced by WTO mechanisms  Macroeconomic parameters as differences in interest rates and changing currency exchange ratio (US Dollar, Yen, Euro) prevent or accelerate import and exports between regions  Need for boundary conditions (as discussed within the scientific economic field e.g. R. Mundell) between the regions; otherwise: return on investment calculations become obsolete and a whole industry, mainly in high investment production, may suffer. Support Programs Boundary conditions for €-, $- and ¥- currency regions 13 Strong € gives disadvantages compared to products from the ¥- and $-regions !

15 RENEWABLE ENERGY FOR EUROPE - RESEARCH IN ACTION Price Experience Curve for PV Solar Modules History Forecast 15 Individual companies: Watch out for corresponding production cost decrease with appropriate economy of scale !

16 RENEWABLE ENERGY FOR EUROPE - RESEARCH IN ACTION Is there a necessity for 2nd and 3rd generation technologies to replace c-Si wafer technology for module production cost below 1 €/W ? No, but utilize new features of thin film and new concept cells to serve additional customer needs! Technology Evolution 16
