Envision's Solar Tree with CleanCharge.
Envision Solar IS currently manufacturing solar trees for General Motor's parking lots. They have signed an agreement with GM to provide its corporate sites with parking lot chargers and soon after its dealerships... The Chevy Volt will be truly green! One parking lot 'tree' can charge six to eight electric vehicles in a day.
Envision Solar’s Solar Tree® with EnvisionTrak™ has dual access tracking which tilts the solar array toward the sun - and follows it throughout the day. The tracking system is 20-25% more efficient than stationary panels.
