Cost Effective Distributed Generation Single Axis Tracker
Controller
Working principle:
HWL horizontal single axis tracker controller, using AC power
supply, with small volume, cast aluminum chassis, 25 years no rust,
installed on the torque tube, easy installation. The core
technology of our solar tracker control system is based on the
local longitude, latitude, time, the program can automatically
calculate the azimuth Angle and altitude Angle of the sun's
trajectory and its location at any time.
Unlike traditional fixed mount plants, single-axis tracking systems
need more space per module for the rotation of the PV modules and
to eliminate possible shading. However, the newest innovation in
this field is to optimize site design by adjusting the layout to
accommodate greater modules unique to its specific latitude and
vertical tilt angle.
The use of solar trackers is increasingly on the rise in PV solar
plants because it allows a significant gain in energy production;
hence, improving project performance. Tracking systems cost more
than the fixed mount PV Plants but the 25% gain in energy yield
could significantly bring down the cost.
