SDE3/SDE7/SDE14 Dual-axis Slewing drive

Description

High-Performance Slewing Drives for Solar Tracking Systems

Overview

Our range of slewing drives is specifically designed to meet the diverse needs of solar tracking systems. Available in 10 different sizes from 3″ to 25″, our more than 60 models cater to both regular and precise tracking requirements across various PV systems, including oblique tracking systems, flat single tracking systems, CPV, and solar thermal power tracking fields. Our slewing drives deliver higher output torque and holding moment torque, ensuring excellent tracking precision. Additionally, they feature anti-corrosion coating, anti-UV sealing, and IP66 protection class, making them ideal for use in PV, CPV, and CSP systems.

Quality Assurance

We maintain a strict quality control system in our own factory, ensuring every product meets high standards. Our products have passed the ISO9001-2008 quality system certification and comply with national engineering and machinery standards.

Applications

Dual-Axis Solar Tracking System

Our slewing drives are ideal for dual-axis solar tracking systems, which track the sun in both altitude and azimuth to maximize solar energy capture. These systems can increase power generation by 25% to 40% compared to optimal inclination angle power generation systems. Dual-axis trackers are particularly suitable for middle-high latitude areas and can be used in residential, commercial, industrial, or utility-scale solar power generation sectors. The high precision of our slewing drives ensures fully automatic tracking, achieving approximately 45% more power output than fixed mounting systems. Additionally, our slewing drives are easy to install, handle, and maintain.

Key Features

• High Output Torque: Enhanced performance for more challenging applications.
• Excellent Tracking Precision: Superior accuracy for maximum efficiency.
• Anti-Corrosion Coating: Prolongs the lifespan of the slewing drive.
• Anti-UV Sealing: Protects against UV radiation damage.
• IP66 Protection Class: Ensures resistance to dust and water ingress.
• Wide Application: Suitable for PV, CPV, and CSP systems.
