Horizontal single axis tracking system
Horizontal single axis tracking system means that PV modules are mounted on a horizontal axis and track the sun in the east-west direction along the horizontal axis. Horizontal single-axis tracking system is mainly composed of: solar cell module mounting bracket, horizontal rotating shaft, rotating driving mechanism, wind speed detection device and tracking controller.
The 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).
