Sunfolding TopoTrack™ Solution Reduces Earthwork by 97% on Any Terrain

Featuring shorter tracker rows, TopoTrack improves terrain handling and constructability for large-scale solar and distributed generation

ALAMEDA, Calif., Sept. 15, 2022 /PRNewswire/ — Sunfolding, a supplier of innovative, US-made solar tracking technology, today announced a solution for projects on variable terrain that virtually eliminates grading within the solar array boundaries. Using Sunfolding’s AirLink technology, TopoTrack’s mechanically independent, scaled-down tracker rows minimize lost land within the fence line and at sites that were once considered off-limits to solar.

Sunfolding’s new TopoTrack™ solution virtually eliminates grading for solar projects on variable terrain.

Sunfolding will display TopoTrack™ in the Solar Power International exhibition hall at RE+, September 20-22, in Anaheim, Calif. Visit Booth 1220 to see TopoTrack™, learn about the Sunfolding T29 Single-Axis Tracker, and meet the Sunfolding team.

TopoTrack™ features two posts, two actuators, and two purlins. By shortening row length, TopoTrack™ improves slope tolerance between rows and expands the boundaries of where solar can go.

“Sunfolding is driven to challenge conventional wisdom about solar project development on any land. You no longer have to flatten your site to make it suitable for trackers. TopoTrack™ maximizes both capacity and yield while virtually eliminating grading,” said Glen Davis, chief executive officer of Sunfolding. “We’re making solar projects easier to develop, build and operate, and more profitable to own.”

The posts, actuators, and purlins for TopoTrack™ ship from US production facilities. Sunfolding sources over 90 percent of the tracker bill of materials from a 250-mile radius in the Midwest, delivering shorter lead times and reduced procurement risks.

“Passage of the Inflation Reduction Act is pointing to unprecedented solar growth and a shift towards infrastructure with low impact on the planet combined with positive impact on the US economy. This is what Sunfolding provides,” added Sunfolding Founder and Chief Technology Officer Leila Madrone. “Sunfolding makes it possible to build solar plants with no grading and no disruption of natural ecosystems due to the flexibility of our unique drive system. And our mechanical and structural components are domestically sourced from the US auto industry.”
