Dual Axis Tracker

Dual Axis Tracking System (DAT)

This tracker model has fulfilled the dream of tracking the sun all day in azimuth and elevation angles. Generally speaking, DAT has a maximum power generation compared to all tracker models and about 45 percent more power compared to Fixed PV System (about 25% in China).

Applications of DAT have ranged from Photovoltaic to High Concentration Photovoltaic (HCPV), such as solar tower thermal, heliostats polyethylene, or Sterling Optical power system. Macsun Solar has been focused on developing and designing precision HCPV Trackers since 2007.

With a hybrid controller program containing a calendric and sun sensor, its tracking accuracy has reached +/- 0.1 degree.

The test result has been recognized by RETC (Renewable Energy Test Center) in California. RETC has completed a six month outdoor test on MST’s dual axis tracker since October 2013 to May 2014 near 50 miles east of Las Vegas in Nevada USA.

Dual Axis Tracker for PV

DAT has been applied to a PV system (silicon or thin film panels) installed mostly in northern hemispheres. In these areas, due to low rise of sun position, 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 the purpose of power generation. There are mainly three different models of DAT: MST-100, MST-300/350 and MST-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 backtracking, high wind protection, and preset positioning for panel cleanup and snow mode.

Dual Axis Tracker for CPV

High concentrating solar panels only work with "direct sunlight", since the concentrator solar cells are quite tiny (example: 3.6mm²). Extensive tracking accuracy is required. Macsun Solar has had specialized tracker designs and productions since 2007, specializing in HCPV trackers. With hybrid controller programing on each tracker, tracking accuracy has reached +/-0.1 degree. GST has had long-term relationships with experienced vendors in solar industry.
