Envision Solar International (EVSI) is pleased to announce the successful installation of a second Solar Tree array for the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) at their Vehicle Testing and Integration Facility (VTIF).

Envision Solar completed the installation of the Solar Tree array for NREL four and a half days after the components arrived at the site on a single truck. The Drag and Drop capability Envision Solar offers meant limited disruption at the site and the ability to use the product right away, which was very appealing to NREL.

"I'm proud that we have been chosen again by NREL. They are delighted the Solar Tree deployment went so quickly and without any typical construction problems," stated Desmond Wheatley, Chief Executive Officer, Envision Solar.

"Our drag and drop infrastructure is comprised of engineered modules which enable us to deliver beautiful and complex structures, made simple and risk free for our customers. That's how we minimize installation time and impact to their property."

"The addition of this Made in America 18kW solar canopy incorporating EnvisionTrak and EV Charging supports NREL's R and D mission to integrate electric vehicles and grid systems for enhanced value," stated Tony Markel, Senior Engineer, NREL.

System benefits of the new tree were maximized by integrating the most efficient SunPower E20 solar panels and a compact transformerless bi-polar inverter from Ideal Power Converters.

The Solar Tree structure is designed to withstand 120mph winds and six feet of snow simultaneously; it is the most robust Solar Tree structure Envision Solar has designed to date.
