Envision Solar Files for U.S. Patent for Tracking Solar Tree® System
EnvisionTrak™ Multi-Axis Hybrid Tracking Technology has Increased Output, Decreased Cost

SAN DIEGO (June 2, 2011) – Envision Solar International, Inc., (www.envisionsolar.com) (OTC BB:EVSI), a leading sustainable infrastructure designer and developer, announces the company has filed for a U.S. patent with the Patent and Trademark Office. The application is for the company’s multi-axis EnvisionTrak™ solar tracking systems, which are designed to increase energy output by approximately 20 percent over a standard fixed PV array. Initial installations of the technology are currently underway in Warren and Milford, Mich., New Castle, Penn. and in San Diego this summer.

The patent application describes a “Device for Continuously Reorienting a Solar Panel.” Envision Solar Founder and CEO Robert Noble and company President Desmond Wheatley invented the technology.

CEO Robert Noble said, “We began our development work in 2006 on this tracking technology to increase the output of our fixed Solar Tree® solar canopies. Having achieved this important technology and intellectual property milestone, our team has advanced our previously patented Solar Tree® products into Envision Solar’s next generation—ultra-high output solar parking array technologies. Solar parking arrays have structural and functional requirements which are unique to this new building type including significant limiting factors of specific installation sites. However, our EnvisionTrak™ technology, a hybrid, multi-axis design, provides a highly functional solution which allows the entire Solar Tree® canopy to track the sun, while not restricting traffic flow in drive aisles of parking lots.”

Envision Solar is pursuing an aggressive technology and product development program, including fully integrated EV charging stations. The company’s intellectual property portfolio is growing, and Envision Solar is nearing the establishment of a new archetype for the renewable energy and building industries—“smart” solar integrated infrastructure and building systems.

Envision President Desmond Wheatley said that demand for the company’s new Tracking Solar Tree® System is coming from every sector: utilities, corporations, military, municipalities, departments of transportation, cities, electric vehicle manufacturers and dealers, and many other markets. “The EnvisionTrak™ integrated Solar Tree® product satisfies these markets’ need for robust, infrastructure quality, high utility, high design, low-maintenance distributed solar energy production,” He said.

Wheatley added, “Our company has long been recognized as the leading inventor and project developer of solar parking array systems, with projects installed throughout the U.S. including Dell Computer Headquarters in Round Rock, Texas and the National Renewable Energy Labs in Golden, Colo.” Wheatley said the new EnvisionTrak™ technology can now provide a greatly reduced cost of generation for customers, and far more clean energy output from each installation, while still providing much-needed shade for cars and people, and an architecturally beautiful enhancement to the neighborhood.
