GST - Model DAT - Dual Axis Tracking System
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.
High concentrating solar panels only work with "direct sunlight" because the concentrator solar cells are minute (example: 3.6mm ^ 2). Extensive tracking accuracy is required. GST has had specialized tracker designs and productions since 2007, with particular specialization in HCPV trackers. With hybrid controller programming on each tracker, tracking accuracy has reached +/-0.1 degrees. GST has had long-term relationships with experienced vendors in the solar industry.
