HCPV: High Efficiency…and Headroom Efficiency Comparison of Solar Technologies

Best at High Temperatures

Consistent Energy Production Peak Demand

Highest Energy Production

Compelling Cost Advantage CPV has a leading LCOE in its target market Higher consistent energy production Increasing system efficiency Decreasing manufacturing costs Source: GTM Research 2011

Minimum Environmental Impact Optimum use of land No permanent shadowing Preserved wildlife corridors Minimized water runoff erosion Distributed generation Dual land usage possible Flexible layout of sites Minimal land coverage/disruption Best cradle-to-cradle footprint Low lifecycle GHG intensity High recyclability (97%) Short energy payback No water consumption Land use for site generating 1 GWh/Year with: SolFocus 25% CPV 11% Efficient Thin Film Material Content 16

Rapid Deployment and Scalability Fields Can be Deployed Rapidly - Fast Time to Cash Projects can be Flexible in Deployment and be Taken Operational in Phases to Deliver Early Project Revenue Highly Scalable Manufacturing with Low CapEx for Manufacturing Installed CPV Manufacturing Capacity Currently 2-3X Forecasted Demand Rapid Expansion as Market Growth Accelerates
