Agenda

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


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)
