1 Fichtner s activities in Solar Engineering Georg Brakmann Managing Director Fichtner Solar GmbH 1

2 Company Brief International leading solar engineering consultant, established in 1999 The solar company of the Fichtner group 25 solar projects in 12 countries on 5 continents Engineering for three of the four GEF supported large ISCC 6 B total investment volume of consulted projects 2 B for 6 large solar projects under construction 25 highly motivated and qualified employees in FICHTNERSOLAR Access to all 1900 staff of complete Fichtner Group. Operational activities completely merged with Fichtner in 2010 Carbon neutral: Engineered, financed, procured, constructed and operates own PV power plant in Spain 2

3 Goals of FichtnerSolar Advance the application of solar technologies Technology Development Center of Excellence for Solar Engineering Cooperation with all members of the Fichtner group Carbon neutral Fair financial return 3

4 Advance Application of Solar Technologies (Political Lobbying) ESTIA (European Solar Thermal Industry Association) World Bank: 200 M$ GEF grant for four ISCCs Solution of ISCC crises Spanish feed-in law BMU 10 M ZIP program Publications and networking within the solar community 4

5 Excellence in Solar Engineering Participation in technical development of EuroTrough solar collector Developed own solar performance software (SOLPRO) Visualization of solar plant layouts Competence building through training and transfer of responsibility to younger employees 5

6 Solar Heat (MW-th) Jun dumping to storage from storage direct used Solar Heat SOLPRO Software Time (hr.) Thermal storage transfers excess solar heat into evening hours. MWe Electricity Generation High air temperatures at midday result in reduced gas turbine performance. Solar electricity is produced when most needed by the grid. 21. Jun Solar generation Solar loss Fossil Generation Time (hr.) SOLPRO calculates 8760 hourly performance values of a reference year. 6

11 Solar Irradiation Direct on normal plane Direct Direct on horizontal plane Diffuse Global = Diffuse + Direct Different technologies use different type of irradiation. 11

12 Irradiation (W/m2) Dec DNI Incident Irradiation Solar Irradiation Time (hr.) Solar Irradiation Irradiation (W/m2) Jun DNI Incident Irradiation Solar Irradiation Time (hr.) Higher solar elevation angles in summer result in larger usable irradiation. 12

13 Technology: Parabolic Troughs First invented in Stuttgart

14 Technology: Parabolic Troughs 1984: small scale experimental solar power plant in Almeria 1912: 55 kw by Shuman in Egypt 14

15 Technology: Parabolic Troughs EuroTrough / Skal-ET California: 354 MW installed by Luz in and operating permanently since then 15

16 Technology: Parabolic Troughs 16

17 Technology: Fresnel, dishes, tower Fresnel Concentrators BMU sponsered development program Lower material costs but also lower efficiency Parabolic Dish with Stirling Engine Highest efficiencies (close to 30%) Suitable for decentralized small scale electrification in remote areas Power Tower Interesting technology due to high efficienyies and thermal storage More R&D needed 17

18 Solar Chimney Invented in Stuttgart by Schlaich Bergermann Solar Experimental (Manzanares) Future Solar Chimney Plants Capacity 50 kw 5 MW 30 MW 100 MW 200 MW Tower height 195 m 550 m 750 m m m Collector diameter 244 m m m m m Solar chimneys work on global irradiation and do not need cooling water. However only a small scale pilot plant was built. 18
