Photovoltaic Applications & Formats Thinking Outside the Rectangle Ted Walker
Tubes For Commercial Applications • Lower Installation Costs • Installed using lighter weight hardware due to lower wind resistance • Does not need to be tilted and directed to the sun
Tubular Photovoltaic Ability to capture sunlight across a 360-degree surface Direct Diffuse Reflected Currently being sold by Solyndra
Each cylinder is one inch in diameter and made up of two tubes. • Solyndra uses equipment it has developed to deposit up to 150 CIGS cells on the outside of the inner tube. • A proprietary light concentrating coupler is added on top of the CIGS cell.
Solyndra Installation Process • CIGS – (copper, indium, gallium, diselenide) photovoltaic printed on glass tube • 14% Efficiency http://www.solyndra.com/Products/Videos
Tubular design can cover nearly double the roof space, producing more annual electricity.
Currently only being marketed for commercial rooftops. • U.S. has 30 billion square feet of commercial rooftop • Could create up to 150 Gigawatts annually 40 cylinders lay side by side in a rectangular frame to form each 1-meter-by-2-meter panel
Photovoltaic Roofing • each shingle produces 17 watts on a clear afternoon • Lightweight & Flexible • Virtually Unbreakable (No Glass) • Shadow & High Heat Tolerant • Thin Film Photovoltaic • Amorphous Silicon Alloy
Thickness can be 100 times less than that of conventional cells • Deposited using a vapor-deposition process at low temperatures • Materials with different light absorption properties can be deposited continuously, one on top of another, to capture the broad solar spectrum more effectively

Odysseus – unmanned, spy wing that flies continuously for up to 5 years in the stratosphere on solar power alone
Photovoltaics – Function & Aesthetics Naturally Inspired Design The Solar Tree Installations in Vienna, Frankfurt, and Milan
Designed By Ross Lovegrove Incorporates 38 mini solar panels connected to individual LED lamps While tested in Vienna the solar trees were able to provide light during the night-time even when the sun did not appear for as many as four days in a row Street lighting consumed 10 percent of all the electricity used in Europe in 2006 or 2,000 billion KWh, and resulted in carbon emissions of 2,900 million ton
