  1. SunSpec Alliance LaunchesTracker Standard Initiative Tracker Standard Technical Briefing

  2. Today’s Presenters John Nunneley Executive Director SunSpec Alliance Andrew Murray Controls Engineer

  3. About the SunSpec Alliance • A federation of 60+ global competitors, collaborators & trading partners • Establish Open Information Standards for PV • Reduce friction and cost • Grow total available market • Promoters of “SunSpec Certified” solutions • Symbol of value and transparency

  4. SunSpec Alliance Members

  5. Why Data Standards? CUSTOMER Benefits Drive out cost inefficiencies Establish economies of scale Open new markets Catalyst for innovation Metrics for testing & certification Highlight best practices Drive out cost inefficiencies Leverage economies of scale Component interchangeability Platform for policy directives Establish minimal quality specs Protect existing investments SUPPLIER Benefits

  6. Where Do You Start? Component definitions and data models Plant, Inverter, Module Units of measure kWh, Irradiance, Volt, VAR 1-minute sample, 15-minute sample Encoding Integer, floating point Transports TCP/IP, Modbus Access methods Web service, SQL Output formats Excel, application specific Things To Standardize

  7. SunSpec Alliance & Smart Grid • SunSpec Inverter Monitoring specification • IEC 61850 harmonization • Smart Energy 2.0 harmonization • SunSpec Inverter Control specification • Volt/VAR control • Curtailment • Ancillary services • De facto standards via adoption & deployment

  8. SunSpec Showcase Program • Simultaneous, multi-application, monitoring of live PV plants • Program highlights • Expert symposium on scaling solar deployment in smart grids • Live solution demonstrations • SunSpec Certified “Showcase” plants • Delivered in partnership with leading global cities

  9. SunSpec Performance Payoff • More accurate system sizing • Impacted by inaccurate de-rating and poor feedback loop • Potential to decrease total system cost • Higher plant uptime • Impacted by lack of global visibility • Potential to dramatically increase availabllity • Increased predictability • Expectations (financial impact, performance ratios) • Forecasting (capacity planning) • Higher return on capital for customers and suppliers SunSpec compatible PV plants install in less time, produce more energy, and generate higher profits for the entire supply chain

  10. Technical Committee Overview John Nunneley, Executive Director John@SunSpec.Org January 2013

  11. Technical Committee Charter • Identify where standards are needed • Define interoperability requirements • Recommend existing standards • Create standards where none exist • Information models for PV Plants • Data interchange format • Best operational practices • Work with International community to promote the use of standards

  12. Standardization Partners • NIST/SGIP Smart Grid Interoperability Panel and roadmap • IEEE 1547/P2030 Interconnection guidelines and interoperabilitywith the electric power system • IEC 61850 Communication networks and systems for power utility automation, logical nodes, protocol mappings • EPRIAdvanced Functions for Distributed Energy Resources • ZigBeeSmart Energy 2.0 specification • UPVI Specification for module electronics • SolarTech Solar 3.0™ Standards for permitting & interconnection

  13. SunSpec Philosophy • Use existing standards when appropriate • Keep it simple • Bottoms-up approach • Membership driven • Focus on quality

  14. Standards Development Methodology Customer Certified Product Technical Proposal Technical Leader Interoperability Testing Open Specification FocusedWork Group
