Transcript

  • 1. Solar Future Strategy Conference Let’s talk about PV-inverters 8. June 2010 Christoph von Bergen, CEO, Sputnik Engineering AG
  • 2. Agenda  About Sputnik Engineering AG  Technology Trends ■ Efficiency ■ Quality ■ Lessons from other sectors  Market ■ Applications ■  For special conditions ■  Standard residential plant ■  Industrial roof and land projects ■ Grid parity needs more grid management ■ Price ■ Inverter shortage  Conclusion 2 | 6/8/10
  • 3. About Sputnik Engineering AG Founded 1991 Based in Biel / Bienne, Switzerland (Head Office) Subsidiaries in Germany Spain Italy France Sales Offices Czech Republic, Belgium Employees 330 and more than 400 outsourced jobs in exclusive partner companies 3 | 6/8/10
  • 4. Sputnik Engineering Annual Installed Capacity in Megawatts MWac Annual increase in MWac Expected annual increase in MWac 4 | 6/8/10
  • 5. Products Product Portfolio 5 | 6/8/10
  • 6. Products Product Portfolio 6 | 6/8/10
  • 7. Technology Trends New technologies have to improve continuously the 3 key aspects: 7 | 6/8/10
  • 8. Technology Trends  Revolution or Evolution?   Currently we can not see revolutionary trends (technology jumps)   Evolution and continuous improvement is in the focus 8 | 6/8/10
  • 9. Technology Trends  In the context of inverters everybody is talking about efficiency?  Is efficiency strategically the key driver?   In the future, the efficiency values of different manufacturers will assimilate   High efficiency is important, but will become mandatory   The differentiation potential is decreasing 9 | 6/8/10
  • 10. Technology Trends: Efficiency SolarMax showing up with state of the art inverters SolarMax S, SolarMax E-Series, SolarMax MT Series, 1994: Sputnik introduced the efficiency jump 3-Level, SiC diodes first TL-inverter into the market 10 | 6/8/10
  • 11. Technology Trends: Quality All efforts and investments in product quality will increase the reliability. In general the inverter reliability has the biggest impact to the performance ratio of the entire PV- SolarMax 6000S installation. (String inverter: 4600 Wac) Why? contains 1227 components.   An inverter is built with more than thousand components   The integrated microcontrollers (DSP) contain several hundred pages of source code.   Rough electrical conditions at the AC-side (bursts, spikes, etc.)   A breakdown by the PV-inverter mainly causes a total breakdown for the entire PV-installation The importance of the product quality for PV- SolarMax 100 TS inverters is underestimated so far. (Central inverter: 100 kWac) contains 3199 components. 11 | 6/8/10
  • 12. Technology Trends: Quality   Reliable evaluation of product quality needs operation experience with an adequate installed base of test units during a significant period of time.   This is not easy to achieve, therefore only a few reports related to this topic were published yet.   Is Mean-Time-Between-Failure (MTBF) a good benchmark to evaluate reliability/ quality? “Infant Normal life End of life  MTBF calculations are only valid for mortality” the constant „normal life“-phase Wear-out  In this phase MTBF values up to several 100 years are possible   What does MTBF have to do with lifetime? Nothing at all! // First month First year 15 years 16 years Operating time 12 | 6/8/10
  • 13. Technology Trends: Quality We strongly believe that product quality will be strategically important for the future success of our company. For that reason we will invest even more in the relevant business processes:   R&D (reliable designs, extensive field tests)   Purchasing (Supplier evaluation & controlling)   Production (Testing & quality checks)   After-Sales (Fast reaction time on-site or via helpdesk)  Quality management (up to date reports about all inverter- failures to manage a continuous improvement) 13 | 6/8/10
  • 14. Technology Trends   Lessons from other sectors   Higher voltages   1500 VDC   690 VAC   Optimizing overall system performance   Smart grids and power management Source: Cleanfuture™ and Portlant State University 14 | 6/8/10
  • 15. Market trend Applications  Non-homogeneous applications / critical conditions   DC-DC converter or micro inverter (Revival from the 90’s)  Advantages due to multiple trackers (e.g. BiPV)  More components: higher costs and lower quality  Working under rough ambient conditions (coldness/heat, humidity) From 1995 to 1997 Our 160 Wac Micro-Inverter  Extensive to monitor and to exchange (BiPV) mounted at the back side of a  Quality and economics will decide on the success 200Wp PV-module. We run field tests with 500 pieces. 15 | 6/8/10
  • 16. Market trend Applications  Small plants and standard residential applications   String inverters   Good price performance ratio   Inverter location can be selected in a for electronics reasonable environment and customer accessibility   Likely mainstream solution for the next years Top of Europe (Jungfraujoch) Highest PV installation in the world, 3,500 m. above sea level. Start-up 01/2008 Devices: 4xSM3000S 16 | 6/8/10
  • 17. Market trend Applications  Industrial roof / land projects   Central inverters   Optimized for higher voltages   Best price performance ratio   Reduced quantity of components as a basis for less break-downs   All-In-Solutions are available - ready to connect with MV-grid Largest PV installation in France La Réunion, 4.4 megawatts. Start-up 2006/2007 Devices: 1xSM300C, 7xSM100C, 1xSM80C, 2xSM35C, 2xSM30C, 2xSM25C, 1xSM20C 17 | 6/8/10
  • 18. Standards for PV inverters Main Categories Product safety EMC Grid connection & protection EN 50178 (Europe) IEC/EN „61000 series“ VDE 0126-1-1 (Parts of Europe) UL 1741 (North America) BDEW MV-Guideline (Germany) RD1663 (Spain) DK5940 (Italy) G83/1 (UK) IEEE 1547 (North America) And many more… 18 | 6/8/10
  • 19. Standards for PV inverters Each country and/or region has its own standards for PV-inverters ... 19 | 6/8/10
  • 20. Grid parity needs more grid management With the large amounts of unpredictable renewable energies the grid operators have new challenges for the grid management. They easiest access for monitoring and control of the whole installation is through the PV-inverter. The utilities must have the possibility to control the PV-installation.   Power reduction   Reactive power   Fault ride through (FRT) 20 | 6/8/10
  • 21. Cost Reduction What brings the cost down:  Economies of scale   Higher purchasing volumes   New production processes   Internationalization of inverters to increase market volume  Smart design/ topology   Integration of discrete elements   Less components  New components   SiC Diodes, DSP, etc  Higher efficiencies   reducing cost for cooling and housing  Harmonisation of standards   Clean the standard-jungle to a reasonable size 21 | 6/8/10
  • 22. Price development Average price development of string inverters 22 | 6/8/10
  • 23. Shortage Our Capacity Utilization Component Shortage PV-Market Recovery 23 | 6/8/10
  • 24. Shortage What are our bottlenecks?   Capacitors and inductors   Delivery time: up to 50 weeks   Power semiconductors (IGBT, MOSFet)   Delivery time: up to 20 weeks   Semiconductors (DSP)   Delivery time: up to 18 – 26 weeks 24 | 6/8/10
  • 25. Shortage The electronic component shortage is worldwide existent and it is a reaction of the recovering global electronics market. Worldwide turnover ($ bn) 2008 delta 2009 delta 2010 Electronic components 398 -16% 332 +7% 356 PV-inverter sales 2.5 +20% 3 +27% 3.8 PV-inverter demand share 0.3% 0.45% 0.53% PV-inverters have still an insignificant effect and influence on the global electronics market. 25 | 6/8/10
  • 26. Conclusion Our strategic approaches: Flexibility   Close to the customer, feel market needs   Short time to market for new products   Flexible production following the market changes  High quality in products and processes   Excellent After-Sales services  Cost awareness   Keep costs down   Lean management 26 | 6/8/10
