Passive Solar Tracker for Photovoltaic Modules

Incorporating over two decades of experience with tracker design and more than three decades of innovation of new products, Zomeworks has introduced the F-Series Track Rack™ Passive Solar Tracker. It features an integral early morning rapid return system, is shipped partially assembled, is easy to install, and is module specific.

SIMPLICITY AND ELEGANCE: The sun's heat moves liquid from side to side, allowing gravity to turn the Track Rack™ and follow the sun - no motors, no gears and no controls to fail.

UNIVERSAL: Six standard UTR and UTR-F Track Racks™ fit all common photovoltaic modules.

EASY TO TRANSPORT: Universal Track Rack™ is "knocked down" and packaged in one to four (depending on the size of the rack) easy-to-handle boxes that fit conveniently into a pickup truck.

How the Zomeworks Track Rack Follows the Sun...

The Track Rack begins the day facing west. As the sun rises in the east, it heats the unshaded west-side canister, forcing liquid into the shaded east-side canister. As liquid moves through a copper tube to the east-side canister, the tracker rotates so that it faces east

The heating of the liquid is controlled by the aluminum shadow plates. When one canister is exposed to the sun more than the other, its vapor pressure increases, forcing liquid to the cooler, shaded side. The shifting weight of the liquid causes the rack to rotate until the canisters are equally shaded.

As the sun moves, the rack follows (at approximately 15 degrees per hour), continually seeking equilibrium as liquid moves from one side of the tracker to the other.

The rack completes its daily cycle facing west. It remains in this position overnight until it is "awakened" by the rising sun the following morning.
