Zomeworks UTR020 Universal Track Racks are designed to fit most common photovoltaic modules. This flexibility translates to faster delivery, better quality and overall economy. The UTR020 Track Rack features an integral early morning rapid return system, is shipped partially assembled, is easy to install, and is module specific.
How the Universal Track Rack™ Follows the Sun
The UTR 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 15o 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.
