13. K2 Solar Confidential What Went Wrong at Solyndra?  Groundbreaking Technology beaten by the market  Unique design enabled 20% greater energy harvest from reflected light  Reduced Balance of System (BOS) costs  Simplified installation- No anchoring  IRS Private Ruling to include roofing costs in 30% Investment Tax Credit  High cost structure (fully automated production line)- could not ramp volume and reduce costs as quickly as market  Misrepresentation by management

14. K2 Solar Confidential Aug 2011 Declared Bankruptcy $100M in Revenue Sep 2010 Fab 2 Opened ~60% Drop in Price Effects of Government Industry Support 2006: First systems installed  Solar Trade Tariffs  2013 Solar PV Cells Manufactured in China: 31%+  2014 Solar PV Modules Manufactured in Taiwan and China: 26%-59%  7 of top 10 PV module manufacturers are now in China SOLYNDRA TIMELINE

15. K2 Solar Confidential Shift in Solar Cell/Module Manufacturing 15 Source: NREL  Solar PV Module Costs  ~50% of module cost driven by cost of polysilicon wafer  Polysilicon Cost -2007: $450/kg -2015: $18/kg

19. K2 Solar Confidential How Solar Saves Money  Utility Rate Schedules  Residential: Tiered Structure  Rates increase as the consumer uses more energy. Solar shaves off top tiers (most expensive)  Commercial Rates: Time-of-Use (TOU) Structure  Energy (kWh) and Demand charges (kW)  Energy (kWh)- Actual energy consumed over time:  Demand (kW)- Energy draw rate: Set by any 15-minute interval in the entire month  Net Metering  Solar produces ~70% of its annual energy during summer months between 9a-4p  Allows over-production (kWh) in summer months to create credits ($) that offset debits in the winter months.  Monthly Statements with Annual True-up Billing

23. K2 Solar Confidential Solar Financing  Equipment Loans  Residential: 15-20 year loans. Homeowner owns solar system. (Remaining Electric Bill (with Solar) + Loan Payment < Existing Monthly Electric Bill)  Commercial: 5-7 year commercial loans (Short term = Negative cash flow), Solar eqpt is collateral  Leases  Residential: 15-20 year Leases where 3 rd party installs, owns, and maintains the system (Remaining Electric Bill (with Solar) + Lease Payment < Existing Monthly Electric Bill)  Commercial: 5-7 year Operating Leases (off-balance sheet, purchase @FMV at end of lease). Short term => high payments => Negative cash flow  Power Purchase Agreements (PPA’s)  3 rd Party installs, owns, and maintains systems.  Property owner pays for all energy generated by system for $/kWh price + annual price escalator.  Limited benefits to property owner. 3 rd party gains cost savings, tax benefits, incentives, and depreciation deductions  Property Assessed Clean Energy (PACE) Financing  Property owner obtains loan from local County. County puts special assessment on property taxes. Property owner pays back loan over term (up to 20-years) with additional payment on property taxes.  County sells municipal bond (PACE bond) to private accredited investor  Funds flow through County to property owner to pay for system  Off-balance sheet, automatically transferable upon sale

24. K2 Solar Confidential Emerging Trends in Solar Market  Solar PV + Energy Storage  Solves problem of intermittent generation from solar/wind  Reduces customer demand charges  Li-Ion battery systems & Flow batteries- Vanadium / Zinc / Aqueous Hybrid Ion  PACE (Property Assessed Clean Energy) Financing  Loan against the equity in the property and invoiced as assessment on property taxes  Covers any Energy Efficiency and/or Renewable Energy Project  No Capital & Cash-Flow Positive Solar Deals  Off Balance sheet and no additional debt load  Automatically transferable upon sale of property  Government Policy  Reduction of Federal Investment Tax Credit  State incentives programs for renewables  National Energy Policy  Utility Pushback  Although small, Distributed Solar threatens utility monopolies and business model  Efforts to eliminate Net Metering, Shifting cost to Demand rates, Fixed charges for solar  SolarCity’s Grid Logic (Micro-grids) & SunVerge (Solar Integrated Storage)
