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).
