Tracstar Solar Trackers are racks for photovoltaic panels that follow the sun to increase the daily power produced. They are azimuth trackers with provisions for adding an elevation drive for dual-axis tracking. Our testing has shown azimuth tracking to produce over 96% of full tracking output with no adjustments, so we only recommend dual-axis tracking for large systems, wind protection, or optical requirements.
Tracstar trackers are made up of three components; the electronic controller, the hub, and the rack to hold the PV panels. The various hub sizes are defined by the maximum square footage of panel they can carry.
We can build any size tracker. Smaller sizes are off the shelf.
We have two rack systems. The usual is shipped UPS complete from the factory for your application and just needs to be bolted together. The second system saves shipping costs because you purchase pipe for it locally. Since the panel brackets are modular, the system can be configured in any way and changed at any time. The overall cost is greater, but there is greater flexibility.
We offset adjacent panels to reduce wind loading. The racks can be assembled with all panels on the same plane, but the hub capacity is reduced.
The azimuth drive motor is protected by a shear pin similar to lawn mowers or outboard motor propellers. During extreme winds this pin will break and protect the motor. The tracker will rotate until it is perpendicular to the wind so the installation should provide for full 360 degree rotation. Replacement (spare included) is done with simple tools. Models without a shear pin and/or with dual motors are available for critical installations in unattended locations.
We would prefer to provide a price specifically for your application
using information from the following simple questionaire.
If you will send us this information, we will quote on a tracker and possibly an alternative.
The following can be used to figure an approximate price.
We recommend that you step up to the next larger tracker if your panel area exceeds 75% of the rated area.
That results in a conservative design and leaves room to add panels in the future.
