Tracker is the Best Solution to increase power generation for solar energy.

    Power generation can be increased by 15% to 45% according to different longitude, latitude, and climate conditions. Generally, the Horizontal Single Axis Tracking system ( HSAT ) is suitable for low latitudes. In high latitudes, the Horizontal Tilted Single Axis Tracking system ( HTSAT ) and Dual Axis Tracking system  ( DAT ) are ideal. In the same location, single axis trackers can increase power generation by 15% to 25%, and for dual axis trackers power generation can increase up to 45%.

Single Axis Tracking System

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.

 

Main characteristics of GST's Single Axis Tracker are：

•    Structural designs with hot dip galvanized steel within a tracking system composed of a linear actuator, distant remote hybrid controller, and anemometer resisting frequent typhoons in Taiwan

•    North south arrays, 45 degree tracking east west

•    Back-tracking feature

•    One controller commanding 12 trackers with a quick installation program

•    Low power consumption with just 0.02 kWh per day per tracking array

•    485 communication features to properly relay system warning or error messages

•    50 years of structural design that meet local building standard requirements

•    Safety mode for high winds and typhoons

•    System base built with optional driven pile, premade concrete pile, or onsite pulled concrete block

                                                                                                

Dual Axis Tracking System (DAT)

   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.
