The Ultimate Guide to Slew Drives for Solar Tracking Systems

In the quest for maximum energy yield, solar tracking systems have become essential. At the heart of these sophisticated systems lies a critical component: the slew drive. This guide delves into everything you need to know about this pivotal technology.

What is a Slew Drive and How Does it Power Solar Tracking?

A slew drive is a compact, high-torque rotational actuator. It combines a slewing bearing, a worm gear, and a housing into a single, robust unit. In solar tracking, it provides the precise, controlled movement that allows photovoltaic panels or mirrors to follow the sun’s path across the sky.

Core Components and Engineering

The durability of a slew drive comes from its integrated design. The slewing bearing handles axial, radial, and moment loads, while the worm gear setup offers high reduction ratios and self-locking capabilities, ensuring panels stay securely positioned even in high winds.

Key Advantages of Using Slew Drives in Solar Arrays

Choosing the right drive system impacts efficiency, reliability, and lifetime cost. Slew drives offer distinct benefits:

High Torque in a Compact Design: They deliver exceptional rotational force from a small footprint, ideal for space-constrained installations.

Precision and Reliability: Engineered for smooth, accurate movement, they ensure optimal sun alignment for years with minimal maintenance.

Integrated Solution: By combining multiple functions, they simplify system design, reduce parts count, and enhance overall structural integrity.

Selecting the Right Slew Drive for Your Project

Not all slew drives are created equal. Key selection criteria include torque capacity, backlash requirements, sealing against dust and moisture, and corrosion protection.
