Solar Tracker STP SA-20
Description
The solar tracker uses our innovative differential system, so even in heavy cloud cover it is able to find the optimal position.
Flat liquid collectors can also be successfully mounted on the tracker.
The tracking system is very energy-efficient, energy consumption does not exceed 2kW/h per year. A certain innovation isfollowing the Sun in one plane(our own design of the electronics system). The tracking system is very energy-efficient, energy consumption does not exceed 2kW/h per year. A certain innovation is following the Sun in one plane), this is done in a wide range of angles. The angle of rotation in the east-west azimuth is 140°. The executive element is oneelectric actuator with a power of 50W,it can be powered by direct current from a battery with a nominal voltage of 24V or from a stabilized mains power supply (our own design, an additional paid option).
Special bearings ensure smooth operation of the system and very long use.
During the night, the tracker sets itself in the east position, waiting for the Sun to appear.The control electronics are mounted in a hermetic plastic housing, resistant to adverse weather conditions. The steel structure of the tracker is designed to withstand strong gusts of wind, and is also very easy toassemble and disassemble. The structure can be disassembled into parts, making it easy to transport.
The highest quality of workmanship ensures long service life and low risk of failure. Simple construction and proven solutions make the tracking system very effective and economical in terms of operation.
