Single-Axis Solar Tracker STP SA-20
Maximum solar output thanks to our innovative differential tracking system.
Thanks to our special EOD differential tracking system, the solar tracker always aligns itself optimally, ensuring maximum energy yield – even in diffuse light.
Low-profile precipitation collectors can be mounted on the tracker at any time.
The tracker operates with exceptional energy efficiency, consuming just 2.0 kWh per year. Our innovation lies in the fact that the tracker does not merely follow the sun’s daily path; when it is cloudy, it automatically seeks out the optimal angle for available sunlight. The east-west azimuthal rotation range is 140°. The unit features a 50 W electric actuator and can be powered by a 24 V DC battery or a stabilized power supply.
Heavy duty and low-maintenance: Special bearings for continuous operation.
At night, the tracker automatically orients itself towards the east and waits for sunrise. The control electronics are housed in a hermetically sealed plastic enclosure, withstanding even extreme weather conditions. The steel structure is designed to withstand strong wind gusts, is easy to assemble and disassemble, and can be broken down into manageable components even for transport by horse.
Reliable technology – for consistently efficient operation. Superior build quality ensures a long service life and a very low risk of failure. Its simple design and proven technology makes the tracking system particularly effective and cost-efficient to operate.
