Powershed to exhibit at GIE+EXPO 2021 as commercialization process advances and product sales begin.

TORONTO and KNOXVILLE — Solar Alliance Energy Inc. announces that a full patent application has been filed, jointly with the University of Tennessee Research Foundation, for Powershed, a solar powered charging station for robotic lawnmowers. The Company also announced that Powershed has advanced beyond the prototype stage and the latest design iteration of Powershed has resulted in four system sales in July, driven by an increase of 33% in power generation per unit.

Powershed is a solar powered charging station for robotic lawnmowers that aims to simplify and improve the operation and use of robotic lawn mowers. Powershed is a product that allows consumers to cut the cord and place a robotic mower anywhere the sun shines.

Solar Alliance developed the Powershed design in cooperation with a researcher from the University of Tennessee and the patent application has been filed with the U.S. Patent and Trademark Office. Powershed had already filed a provisional patent application with the U.S. Patent and Trademark office, which provided intellectual property protection pending a full patent application.

“The Solar Alliance team has made significant advances with Powershed by increasing the power output of the charging station and decreasing costs,” said CEO Myke Clark. “Our goal has always been to move beyond the prototype stage with a prudent technology development plan and then market Powershed to a broader audience. With the filing of our final patent application, combined with the technology advances we have seen, we are now prepared to begin a broader marketing campaign targeting larger customers and partners.”


In support of the retail and commercial launch of the latest version of Powershed, the Solar Alliance team is scheduled to exhibit and demonstrate Powershed at the GIE+EXPO 2021 in Louisville, Kentucky in October.

The current retail price for Powershed is $4,500, although the Company expects to achieve a significant cost reduction as manufacturing capacity and sales increase. Powershed is designed to meet demand through a scalable production model and will initially be offered through commercial distribution partners and direct sales. The possibility of sub-licensing the product to robotic lawnmower manufacturers exists and will be pursued as demand increases.
