Series A Funding (Aug 08) Solar America Initiative (Feb 09)

• ~$25M Series A led by NEA • Up to $3M grant to fund technology • NEA has $8.5B under investment commercialization projects and has funded more than 550 • Only systems company selected by the firms Department of Energy

“We think this company is going to be one of the survivors. They’ve got “We were impressed by Skyline's total system approach which substantially lower costs because of the way they’ve designed this. packages many high gain solar design elements into an elegant array It’s more than just a clever idea. ” leveraging traditional manufacturing for large scale.” Mark Perry, General Partner, NEA Martha Symko-Davies, Research Senior Supervisor, NREL

Demonstration Power Plant (May 09) Volume Production Partnership (Oct 09)

• 27kW power plant at Santa Clara Valley • Partnership with Cosma Transit Authority (VTA) International’s U.S. stamping and • Commissioned May 15; >2000 hours of assemble facility on-sun data • Skyline High Gain Solar Arrays • Field data confirms performance designed to fit automobile metal shop models “design rules” • Reusing America’s industrial base and retaining American jobs “Thanks to Skyline Solar, our first significant solar installation is now up ”We are excited to be manufacturing the Skyline HGS system and, by and running and is providing VTA with clean, renewable energy and doing so, contributing to America’s move toward energy a unique learning experience” independence.” Michael Burns, General Manager, Santa Clara VTA Horst Prelog, President, Cosma International

Tracked PV High capacity factor Materials intensive: silicon, metal, concrete High Gain Solar PV Combines best of both approaches Works on distributed and utility scale Silicon + Tracker

Reflector + Tracker SILICON + REFLECTOR + Solar Thermal TRACKER Dispatchable but capital intensive Only works on a massive scale

A dramatically simplified approach with just 2 major components:

1 HGS 2 Reflective Rack • Mounts verticallyPanel• Along rails • Facing Inwards

• Structural support

• Curved Reflector

• Integrated Tracker

Pre-assembled HGS Panel Reflective Rack Modular System • 85% less silicon • Breakthrough System • 67% fewer parts assembled in field • Low cost design Architecture – Separates light capture from • Plug & play array built from a – Fraction of materials needed power generation vs. standard panels few pre-assembled modular – Integrated racking and elements • Efficient thermal management tracking – Vertical orientation and heat • Reflector doubles as space sink improve cooling frame structure • Manufactured in existing module factories • Streamlined logistics • 100% recyclable materials • Compare to fixed tilt system built with many parts assembled in the field

Innovative heat sink keeps cells cool

HGS Panel uses 50kW per standard silicon cells container

Skyline installations give the option of power plant upgrades

Roll Stamp Assemble Stack

. Manufacturing process and line designed for standard metal fabrication equipment

. Easily adopted by automotive factories, HVAC sheet metal manufacturing plants, etc.

. Skyline partnership with Cosma International’s US stamping and assembly facility

. Faster energy payback • More Watts per pound of material • Reduced embodied energy . Lower carbon footprint • System almost entirely manufactured out of recyclable metal • 85% less hard-to-recycle materials: silicon, solder, encapsulents

Benefits of novel, patented architecture • Cost HGS reaches grid parity ahead of the pack • Capital Efficiency Factory CapEx as low as $0.08/Watt • Upgradability The world’s first upgradable solar power plants • Reliability Elegant design based on proven materials • Scalability Factory integrated systems yield fast low cost installations
