Backtracking Solar Sun Tracker Utility Scale Easy Operation
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).

Pastoral Complementary
Single Axis Solar Tracker can be used in pastoral industry, it refers to the combination of animal husbandry and photovoltaic power generation, normally photovoltaic panel can be installed on above the farm and prairie, cattle and sheep can be feeding under the area below the photovoltaic pane, also the PV panels can provide a good cover protecting for the animals under their shadow. The development of photovoltaic power generation and animal husbandry can eventually form a good ecological co-development model.
Land Photovoltaic
Land photovoltaic power station refers to the construction of photovoltaic power station under different terrain conditions such as mountains, hills, desert, wasteland etc. The construction of surface ups and downs, different orientations, the terrain can be used irregular, scattered. Good Future Solar Technologies Co.,Ltd. Will help to design the project according to terrain condition, location and customer requirements.
