Frequently Asked Questions

What is a solar slew drive?

A solar slew drive is a precision gearbox that rotates solar panels or mirrors to track the sun’s movement, maximizing energy capture throughout the day.

Can you customize the slew drive for our project?

Yes. Our in-house engineering team can modify torque, speed, motor type, housing, and interface dimensions to meet your specific requirements.

What’s the difference between single and dual axis drives?

Single axis drives rotate panels on one plane (typically east-west). Dual axis drives adjust both horizontally and vertically, ideal for high-precision CSP and heliostat fields.

Do your drives work in extreme climates?

Yes. Our IP66-rated, sealed units operate reliably in temperatures from -40°C to +80°C and resist sand, salt, and humidity.
