Maintenance and Care for Small Wind Turbines

Proper maintenance and care are essential for maximizing the efficiency and lifespan of your small wind turbine. This comprehensive guide outlines the necessary steps and practices to maintain your wind turbine, ensuring reliable performance and minimizing downtime. Whether you’re managing a turbine for residential, business, or agricultural use, understanding these maintenance procedures will help keep your system running smoothly.

Understanding Wind Turbine Maintenance

Wind turbine maintenance is divided into preventive and corrective maintenance. Preventive maintenance involves regular inspections and routine tasks to prevent failures, while corrective maintenance addresses repairs after a fault has occurred.

Benefits of Regular Maintenance

  • Increased Efficiency: Regularly serviced turbines operate at optimal levels.
  • Extended Lifespan: Preventive maintenance prolongs the life of the turbine.
  • Reduced Downtime: Minimizing unexpected breakdowns ensures continuous energy production.

Preventive Maintenance Schedule

Creating and adhering to a maintenance schedule is crucial. The schedule should be based on the manufacturer’s recommendations and tailored to specific environmental conditions and operational demands.

Monthly Checks

  • Visual Inspections: Look for signs of wear or damage on the rotor blades and tower.
  • Bolt Tightening: Check and tighten any loose bolts and electrical connections.
  • Noise and Vibration Checks: Listen for unusual noises or vibrations that indicate potential issues.

Semi-Annual Checks

  • Lubrication: Apply lubricant to bearings and moving parts to ensure smooth operation.
  • Brake System Inspection: Test the brake system to ensure it engages correctly and safely.
  • Electrical System Assessment: Inspect wiring, connections, and insulation for signs of wear or damage.

Annual Checks

  • In-Depth Structural Inspection: Examine the structural integrity of the tower, nacelle, and blades.
  • Generator Service: Check the generator and associated electrical components for corrosion or degradation.
  • Performance Review: Assess the energy output of the turbine to determine if it meets expected performance levels.

Corrective Maintenance

When issues are identified during routine checks or turbine performance drops unexpectedly, corrective maintenance is required.

Common Issues and Solutions

  • Blade Damage: Replace or repair damaged blades to prevent further imbalance and vibration.
  • Electrical Failures: Address wiring issues, replace worn components, and ensure all electrical connections are secure.
  • Mechanical Wear: Replace worn bearings and gears that could lead to more significant mechanical failures.

Professional Maintenance Services

While basic maintenance can often be performed by the turbine owner, professional services are recommended for more complex tasks.

  • Annual Service Checks: Have a qualified technician perform an annual service check to ensure all aspects of the turbine are functioning correctly.
  • Specialist Repairs: Utilize specialist services for high-level repairs, particularly for gearbox issues or electrical faults.

Emergency Procedures

Establish a set of emergency procedures for dealing with sudden failures or unsafe conditions.

  • Emergency Stop Systems: Ensure all users know how to engage the emergency stop to quickly shut down the turbine if needed.
  • Storm Preparation: Implement protocols for securing or shutting down the turbine during severe weather to prevent damage.

Record Keeping

Maintain detailed records of all maintenance activities, inspections, and repairs. These records are valuable for:

  • Warranty Claims: Detailed maintenance logs are often necessary to support warranty claims.
  • Resale Value: Comprehensive maintenance records can increase the resale value of your turbine.
  • Operational Analysis: Reviewing maintenance logs can help identify recurring issues or areas for improvement.


Effective maintenance and care are crucial for the successful operation of a small wind turbine. By establishing a regular maintenance schedule, addressing issues promptly, and keeping detailed records, you can ensure that your wind turbine continues to provide reliable, efficient energy for years to come.
