Solar Alliance Energy Inc. has filed a full patent application for Powershed, a solar-powered charging station for robotic lawnmowers. The patent application was filed jointly with the University of Tennessee Research Foundation.
The company also has announced that Powershed has advanced beyond the prototype stage, and that its latest design – which features an increase of 33 percent in power generation per unit – has resulted in four system sales in the month of July.
Solar Alliance developed the Powershed design in cooperation with a researcher from the University of Tennessee. The company had previously filed a provisional patent application with the U.S. Patent and Trademark office, which provided intellectual property protection pending the 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,” says 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.”
Powershed will initially be offered through commercial distribution partners and direct sales; the possibility of sub-licensing the product to robotic lawnmower manufacturers exists, says Solar Alliance, and will be pursued as demand increases. The current retail price for Powershed is $4,500, although the company indicates it expects to achieve a significant cost reduction as manufacturing capacity and sales increase. The Solar Alliance team is scheduled to exhibit and demonstrate Powershed at GIE+Expo 2021.
