Heavy-Duty Screw Jacks in Solar PV Tilt Adjustment Systems

Modern photovoltaic power plants increasingly rely on dual-axis tracking systems to maximize solar exposure and boost power generation efficiency. These systems require precise, stable, and durable actuation to continuously adjust panel tilt and azimuth throughout the day. NUODUN supplied heavy-duty screw jacks engineered specifically for large-scale solar tracking structures.

Application

The system shown integrates a NUODUN worm-gear screw jack paired with a geared motor, mounted directly on the solar tracking frame. This actuator provides controlled, high-torque positioning for the tilt axis of the PV array.

Key Functions

• ±0.5° high-precision tilt adjustment
  Ensures optimal sun-tracking accuracy, enabling the panels to maintain the best possible angle as solar position changes.
• High load capacity for large PV arrays
  Supports the structural weight and environmental loads (wind, snow, vibration) common in outdoor installations.
• Smooth, reliable motion under continuous operation
  Worm-gear design offers inherent self-locking capability to prevent back-driving, ensuring safe and stable panel positioning.
• Outdoor durability
  Corrosion-resistant housings, sealed lubrication, and weatherproof configurations withstand long-term exposure to rain, UV radiation, sand, and temperature cycling.
