IP66 Enclosed Solar Tracker Slew Drive With Hourglass Worm For Solar Concentrated Solar
Description
The slewing drive is essencial part of CSP, concentrated solar power photovoltaic. Concentrated solar photovoltaics and concentrated solar thermal have optics that directly accept sunlight, typically used to orient a mirror and redirect sunlight along a fixed axis towards a stationary receiver. So the system must be angled correctly to collect energy. All concentrated solar systems must have trackers because the systems do not produce energy unless directed correctly toward the sun.
Besides, it need high precision in order to make sure the system can orient sun all the time and make full use of the sunlight.
Types of CSP
There are mainly three types of CSP stations:
1. Tower/Heliostat-sde slewing drive, se slewing drives
2. Parabolic-se slewing drives, ve slewing drives
3. Fresnel- ve slewing drives, se slewing drives
Our Product
With ease-of-use features and high performance, our single axis solar trackers are a simpler, more powerful solar solution to make the system move with the sun from dawn to dusk to maximize energy production thoughtout the day. Our slewing drives are designed to fit installations of all types of solar tracking system.
