Horizontal Single Axis Solar Tracker Control System
Working principle:
Horizontal solar tracker control system, according to astronomical
algorithm, the motor drive the bracket to make the module track the
sunlight, so as to improve the sunlight exposure on the surface of
the PV module as much as possible, thus improving the power
generation.
Solar trackers are devices used to orient photovoltaic panels,
reflectors, lenses or other optical devices toward the sun. Since
the sun's position in the sky changes with the seasons and the time
of day, trackers are used to align the collection system to
maximize energy production.
