Slew Drive Solar Sun Tracker High Terrain Tolerance
Working principle:
A single-axis solar sun tracker follows the sun's azimuth
throughout the day. The tracker points the solar array to the east
in the morning and follows the sun across the sky to sunset in the
west, at which time it returns to its east-facing default position
to await the next sunrise. The single-axis tracker will not adjust
to compensate for the altitude, but the can be manually adjusted
through the year.
The tracking system is controlled by the tracking controller, with
simple structure, easy installation, flexible response, good
reliability and strong fault identification ability. Compared with
traditional fixed inclination installation, the generating capacity
can be increased by 15%-20% (depending on local conditions).
