  1. Photovoltaic and Solar Thermal Systems in GermanyMarket and Technical Development Dr. Uwe Hartmann DGS Berlin Brandenburg e.V. DGS@DGS-Berlin.de www.dgs-berlin.de

  2. DGS activities: • Publications: Manuals PV and Solar Thermal systems • Development of PV simulation software DGS Manuals: Solar Thermal Systems and PV Systems PV Simulation Software SolEm

  3. Local section of the German Solar Energy Society, the oldest nationwide solar organisationin Germany (3.000 members) • Manuals PV Systems, Solar Thermal Systems and Bioenergy Systems in English, Spanish, Italian and Portuguese for experts • “Sonnenenergie” Magazine PV, Solar Thermal and Bioenergy Installers‘ Guide; information: http://www.greenpro.de

  4. Solar School Berlin: • Training for technical and sales staff : engineers, architects, trade workers, sales managers, consultants • since 1996 more than 2000 persons and companies have been trained

  5. Projects with DGS participation • Planning and services for PV and solar thermal projects • Computer simulation and predicting yield of large solar thermal or PV systems for banks and investment societies • Monitoring of solar systems • Quality assurance for solar energysystems:RAL initiative and label

  6. PV-Market in Germany

  7. Solar Cell Turnover p.a. worldwide and Costs in Germany

  8. Situation of Solar PV Market In 2005 installed: appr. 600 MWp In 2006 expected: appr. 700 MWp Turn over 2005: > 3.000.000.000 € Totally installed: > 1,6 GWp Employees: > 20.000 Cost reduction: 60% within 6 years Cost increase since 2004 !

  9. German PV Production Companies Between 1999 and 2004 more than one billion Euroswere invested in new production lines

  10. Feed-in Tariffs in Germany

  11. Market Share of Cell Types worldwide

  12. Cell Types Thin film cells Mono Poly Kupfer-Indium-Diselenid (CIS) Silicon cells amorphes Silizium Cadmium-Tellurid (CdTe) Hybrid HIT-Cells

  13. Technical and Economical Trends Market Share: Cristalline Silicon and Thin Film Cells Market Share: PV-Systems in Buildings and in Rural Areas

  14. Comparison: material use and energy expenditure of cristalline silicon and thin film cells

  15. Trend: BIPV • Standardisation: • Prefabricated elements • Norm for BIPV • Costs are higher but multiple benefit

  16. Trend: BIPV

  17. Trend: BIPV

  18. Trend: movable PV-systems Benefit: Up to 40% more yield

  19. Quality Assurance and Quality of Guarantees given are essential Effectivity of Support Programs for Renewables Important: Not only the yield expected is crucial for the investment decision but also the potential risk

  20. Quality assurance of PV- and ST-Systems RAL-Keymark of the DGS

  21. Financing of PV-Systems • Fonds („Quality criteria for solar fonds“ , UVS and BEE, 2005) • Leasing • Citizens as shareholders of PV-Systems • Roof renting

  22. Monitoring of PV-Systems Sensors for temperature and radiation Datalogger with fault indication Visualisation of yield Monitoring via Internet

  23. Displays Two examples for outdoor and indoor areas Example for indoor area

  24. Solar Thermal Market Growth in Germany

  25. ST-Producers in Germany Producers founded in the `80s Wagner, Solvis etc. The big players Viessmann, Buderus etc. Specialists like Schüco, Roto Frank, Velux

  26. Solar Thermal Trends Solar Air Conditioning Systems Phoenix, Conergy Solar Heating Systems Water Drain Back Systems Wagner, Paradigma Solar Energy Centre Parabel

  27. Berlin: Solar Energy CentreStralsunder Street

  28. Trend: Solar and pellets

  29. Trend: BIST

  30. The Market Incentive Program (MIP) Strong increase of applications in 2006 due to oil and gas price increase Total appr. 160.000 incl. July Mean collector area appr. 11 m2 50% of applications for heating systems Since 08 / 2006 program closed

  31. The Future of ST-Support Programs MIP: Reduction of incentive Till 8/2006: 54,6 €/m2 and 70,2 €/m2 MIP: new incentive based on CO2-emission reduction or kWh produced? Renewable Energy Law for Heating Systems? (Acc. to the REL for electricity)

  32. Solar Air Conditioning • Heating demand of buildings is falling • Comfort demand is rising • Together: cooling demand during summer is rising Example: Location in Southern France

  33. Example of Solar Air Conditioning System (Open System) in Freiburg Southern Germany • 100 m2 solar air collectors • 100% solar fraction during summer • No storage necessary • Only two days (2002) with more than 27° in rooms

  34. Thank you for your attention
