PowerTracker(TM) Solar Electric Systems Generate Maximum Energy

from Daylight

PowerLight Corporation and Shingleton Design have reached an exclusive agreement to pursue the joint development, marketing and sales of PowerTracker(TM) and PowerRack(TM) solar electric systems. Under this agreement, PowerLight purchased patents, intellectual property and other assets developed by industry veteran Jefferson Shingleton.

"This agreement will make it possible for us to focus our efforts on adding product features and supporting the global implementation of these technologies," noted Jefferson Shingleton of Shingleton Design.

PowerTracker systems use non-concentrating solar panels that harvest both direct and diffuse daylight, generating between 17% to 35% more energy than fixed solar panels as they automatically follow the sun's path from early morning to late afternoon. The PowerTracker system is based on a proven low-cost design in which a single motor, drive, and controller moves multiple rows of solar panels. A minimal number of moving parts results in very low maintenance costs.

"I have known Jeff Shingleton and have closely followed the evolution of his solar tracker designs for the last 12 years," said Dan Shugar, President of PowerLight Corporation. "We have productively incorporated his patented product on large projects over the last several years, and look forward to using its unique features to help expand the global solar market."

PowerTracker systems provide clean, reliable, on-site energy that's both economical and environmentally sound. These scalable solar systems deliver maximize energy during periods of "peak" demand -- when the grid is strained and power is most expensive. PowerLight is offering turnkey PowerTracker systems and components for applications of 100 kW and larger.

Forward thinking companies and government agencies are increasingly investing in solar generation for its economic and environmental benefits. On-site solar electric power systems reduce operating costs by transforming clean, abundant solar energy into electricity.
