The dual-axis tracking Solar Tree has been awarded a patent by the U.S. Patent and Trademark office.
By tracking the movement of the sun throughout the day, a Solar Tree with Envisiontrak can produce a significant increase in energy output over traditional static solar arrays, which generate maximum output only when the sun is at its peak, generally between noon and 3 p.m. , says the company.
The first installation is part of an Axion Power Cube installation project, explains the company, with funding recently approved by the state of Pennsylvania’s Solar Energy Program. It will analyze the amount of solar energy that can be generated by the Solar Trees and then stored in Axion Power’s lead carbon PbC batteries. A Solar Tree with Envisiontrak will deliver solar energy during the day with its output compared to that of an adjacent fixed Solar Tree. The energy will then be released to demonstrate how it can be delivered back to the grid during peak usage times.
"EnvisionTrak overcomes one of the biggest objections to fixed solar photovoltaics installations by maximizing the amount of energy that can be delivered during daylight hours," said Bob Noble, CEO of Envision Solar. "By offering the first dual-axis tracking parking lot solar array, we can enable organizations to significantly increase the amount of clean energy that they produce for very little additional cost."
