CPV Technology Recap Overview of the State of CPV Commercialization CPV Energy Yield & Metrics Economic Analysis of CPV Power Plants Opportunities Created by CPV Deployment
Slide 3Patents Pending © SolFocus, Inc. 2010
CPV Technology Basics
Concentrator Photovoltaic (CPV) Utilizes optics to concentrate sunlight onto
photovoltaic surfaces to generate electricity
Requires sunny conditions with direct sunlight
Dual-axis tracking for consistent energy production throughout the day
Concentrates sunlight >500x onto small, high-efficiency, multi-junction solar cells
>2X efficiency of silicon PV cells
Fresnel lenses (plastic/acrylic)
Reflective optics (glass optics)
