Track Racks & Photovoltaic Racks

Since 1980, more than 19,000 Zomeworks single axis trackers have been installed, in different climates, on nearly every continent in the world. Track Racks™ are highly cost-effective components for domestic and industrial photovoltaic power  systems; water pumping systems; cathodic protection systems; and traditional power utilities.

Construction

Major rack components are comprised of welded steel construction.  Years of building solar racks has shown that welded steel construction holds up the best – whether it’s wear and tear from years of wind exposure, extreme temperature variation or severe weather events.  Steel components  give our racks an edge on strength and long term durability.


Module mounting rails are made from 6000-series heat-treated  aluminum.  Our aluminum mounting rails are designed to withstand the  same conditions as the welded components, but offer more flexibility and  options for mounting and also do not require the use of paint.  The  wall thickness has been increased to resist fastener “pull-out” and  provide an extra margin of strength.

Simplicity & Elegance

The sun’s heat moves liquid from side to side.  This action allows gravity alone to turn the Track Rack to follow the sun—therefore no motors, no gears and no controls to fail.


The Track Rack features an early morning, rapid-return system.  Shipped partially assembled, it’s easy to install and is module specific.


Easy-to-transport, the Track Rack is broken down and packed into one to five boxes (depending on the size of the rack).  

   

Design

Zomeworks Trackers are polar, single-axis type.  All of our trackers  move through 90 degrees of rotation. 


The inclination of the tracking axis can be manually adjusted to optimize the performance throughout the  year (in the Northern Hemisphere this means “steeper” in the winter and  “flatter” in the summer).  


This design is very effective, significantly  increases module efficiency and results in a strong, simple, reliable  tracking system.

Passive=Simple

All mechanical things need maintenance at some point.  The heart of  Zomeworks tracking system has no moving parts or electronics – requiring  only the heat from the sun.  All of our tracking racks only require 2  bearings for movement.  


  The bearings on our smallest rack are  maintenance-free, and the larger models have a grease fitting for  periodic re-lubrication.

Models

Six standard UTR and UTR-F  Track Racks fit all common photovoltaic modules. The UTR020, UTRK040 and the UTRF072, -090, -120 and -168  are named for the number of square feet of module area they hold. 


  

Warranty

All Zomeworks products are made in our factory in Albuquerque, New  Mexico.  

Track Racks are warranted for 10 years and 90 mph winds 3  second gusts.  Replacement parts can be ordered through our dealer  network or directly from us. 

Product options, FAQ's, and Pricing.

How do Trackers work?

1. Sunrise

The Track Rack (photovoltaic/solar tracker) 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.  


2. Morning

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.

3. Day

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. 

4. Evening

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.

ALEX 60™ Aluminum Rail

Zomeworks’ engineered universal aluminum module mounting rails are  now integrated into all of Zomeworks Track Rack™ and Fixed Rack product  lines.

It is extruded from 6063 T-6 mill finish aluminum and will accept  standard 1/4″ or 5/16″ stainless steel module mounting hardware. It  weighs less and is stronger than the traditional steel rails. It will be  easier to handle, install, it’s naturally corrosion resistant and  requires no maintenance.

The ALEX 60 rail can be purchased separately, please call for pricing.
Engineering certification for the UTRF168 Tracker for California as  well as New Mexico, using the new aluminum extrusion are available by  clicking the links below.
