For most PV power plants, the Single Axis Tracker is the top pick due to its cost performance ratio. Compared to the fixed system there is about a 10% additional cost, but a 10% to 25% increase of power generation. Thus, the Internal Rate of Return is a benefit. When selecting a solar system, there are three basic categories to consider: the product cost, the installation cost, and the cost of 20 years of maintenance. According to American EPC companies such as SunPower, First Solar and others, there is an additional 10% maintenance cost for tracking systems compared to fixed systems. The benefits of trackers for investors should make them the preferred choice.

DAT has been applied to a PV system (silicon or thin film panels) installed mostly in northern hemispheres. In these areas, due to the low rise of sun position, the array distance for either Fixed or SAT Systems need to be wider, which does not meet economic efficiency standards.  DAT is the best choice for power generation. There are mainly three different models of DAT: GST-100, GST300/350 and GST-400. With 10 to 60 square meter panels on each tracker, one Controller program can command up to 6 trackers. The basic features of the program are back-tracking, high wind protection, and preset positioning for panel cleanup and snow mode.
