  1. Distributed Electronics: More than shade mitigation September 2011

  2. Agenda Distributed electronics market The opportunity Where we’re going Tigo Energy Confidential – Not for Redistribution

  3. Distributed Solar Electronics Market MORE ENERGY MODULE VISIBILITY ENHANCED SAFETY DESIGN SIMPLICITY 3 Tigo Energy Confidential – Not for Redistribution Market is very vibrant and growing rapidly 2011 growth expected to by more than 100% Nearly 2 GW expected to ship in 2014 Tigo Energy now shipping 10,000 u / wk Has become accepted globally

  4. Tigo Energy’s Approach Tigo Energy Confidential – Not for Redistribution • Lower the cost of energy production • Lower the cost of system ownership • Enable IT-based new business models • IT based O&M • Performance based financing • Integrated building management • Performance forecasting & site planning

  5. How? UNPARRELLED EFFICIENCY ADVANCED ANALYTICS “NET ZERO” COST OPTIMAL RELIABILITY Tigo Energy Confidential – Not for Redistribution

  6. Impedance Matching • Algorithm-based approach • Precise mathematical calculation of peak power point for each module • Works with any inverter • No use of trial-and-error • Industry-leading efficiency of 99.5% • 6patents issued; 42 additional patents submitted • Tigo Energy is the only company producing this type of architecture Tigo Energy Confidential – Not for Redistribution

  7. Tigo Energy ™ Maximizer Solution • Lowest On-Module Part Count • Cost scaling • Improved module reliability • Quick path to module integration • Highest Efficiency • Very little heat disappation • Power scaling to 350W and beyond • “Vertical” solution • Use any inverter (on-grid or off) • Use any module type Tigo Energy Confidential – Not for Redistribution

  8. Tigo Energy Product Cost Roadmap Tigo Energy Cost Per Watt Declines Significantly • 2ES product to be announced at SPI (Oct), and shipping in Q4 • Integrated J-Box product expected to ship in 1st half 2012 • Tigo Energy is the only DC optimization product with 350W (and soon, even greater) power output capacity • Further leverage to lower overall system costs Tigo Energy Confidential – Not for Redistribution

  9. Integration Path Note: : Ambient temperature equal to 75F Tigo Energy Confidential – Not for Redistribution

  10. Smart Module-Optimized Inverter • Eliminate boost stage for US inverters • 1.5% efficiency increase • 30% better reliability • 25% cost reduction • US: Longer strings reduce electrical BoS cost by 20% • This neutralizes the only advantage DC-to-DC converters had Cost Reduction Already Pays For Tigo Energy In Residential This Year Tigo Energy Confidential – Not for Redistribution

  11. Energy Harvest Improves Over Time More Energy Energy Harvest Residential (Shaded) Tier I inverter manufacturer retro-fit of 9-year-old site: 35% power improvement • Over time, energy harvest grows: • Projected lifecycle degradation happens at varying speeds • System components suffer undetected failures • Production can be impaired by environmental effects • Soiling accumulates at varying rates Unshaded Time lab test: 3-4% power improvement Tigo Energy Confidential – Not for Redistribution

  12. Tigo Energy on Unshaded System Improves Production by 8% More Energy Tigo Energy Installed on Blue Array Tigo Energy Confidential – Not for Redistribution

  13. Advanced Analytics Enables IT Based Service • Sampling frequency • Every 2 seconds • Sampling accuracy • 0.1% sampling accuracy on I, V • Synchronous sampling • Eliminates time based & environmental “noise” Note: System ID = 20 Tigo Energy Confidential – Not for Redistribution

  14. Tigo Energy Improves Commercial ROI by 20% Note: Assumes 1MW system size, 3.5% incremental harvest in year zero, 0.5% degradation mitigation, and $0.25 FIT with no annual escalator. Assumes no optimized inverter. Tigo Energy project costs yield >50% IRR on a commercial-scale installation Tigo Energy Confidential – Not for Redistribution

  15. Summary • Distributed Electronics • Value beyond shade mitigation Tigo Energy Confidential – Not for Redistribution
