wind turbine maintenance

Home wind turbine, ranging from small wind systems for residential applications to those capable of generating up to 20 kilowatts, are transforming the way homes harness wind energy. These turbines not only offer a clean, renewable, and cost-effective source of electricity, especially in areas with ample wind resources but also significantly reduce utility bills.

Effective maintenance is crucial for maximizing the performance and lifespan of a home wind turbine. Routine checks, every six to twelve months, ensure the turbines operate safely and efficiently, thereby avoiding expensive repairs and extending the turbine’s service life.

Routine Inspection and Preventive Maintenance

Regular and thorough inspections are vital to ensure the longevity and efficient operation of home wind turbines. Here’s a detailed guide to conducting routine inspections and preventive maintenance:

  1. Initial and Ongoing Inspections:
  2. Key Components to Inspect Regularly:
    • Blades and Rotor: Check for cracks, damage, and ensure clean surfaces for optimal performance.
    • Gearbox and Generator: Use a boroscope for internal inspections and check for wear and tear.
    • Electrical Systems: Inspect wiring, connections, and the control unit for damage or wear. Replace worn parts immediately.
    • Structural Integrity: Examine the tower foundation, nacelle, and ensure all bolts are tightened as per manufacturer’s specifications.
  3. Maintenance Tasks:
    • Lubrication: Regularly lubricate moving parts to reduce friction and prevent wear. This includes the gearbox, generator bearings, and blade bearings.
    • Bolt Tightening and Replacements: Follow a strict schedule for inspecting and re-torquing bolts, especially after severe weather conditions.
    • Cleaning and Adjustments: Keep the nacelle, rotor, and other exposed surfaces free of debris and vegetation to prevent unnecessary load and potential damage.

Regular maintenance not only prevents unexpected failures but also ensures that the home wind turbine operates at peak efficiency. By adhering to a structured maintenance schedule and promptly addressing any issues, homeowners can enjoy sustained wind energy production with minimal disruptions.

Cleaning and Lubrication

Cleaning Tasks:

  • Rotor and Nacelle: Regular cleaning is crucial to maintain the efficiency of the wind turbine. Ensure the rotor and nacelle are free from vegetation and debris to prevent operational hindrances.
  • Debris Removal: Clean off any dust, sand, moss, insects, and pollution regularly. These elements can significantly reduce the turbine’s efficiency if not addressed.
  • Use of Cleaners: Employ cleaners like Extreme Simple Green, which is known for its degreasing power and safety on composite materials, ensuring it does not corrode turbine components.

Lubrication Tasks:

  • Regular Oil Changes: Conduct regular oil changes as per the manufacturer’s recommendations to ensure smooth operation.
  • Component-Specific Lubricants: Use the correct lubricant for different components such as gearbox, generator bearings, and blade bearings, considering the turbine’s operating conditions like temperature and pressure.
  • Monitoring and Maintenance: Keep a regular check on the lubrication system and perform oil analysis to detect any contaminants or signs of wear. Change the oil at recommended intervals to avoid increased friction and wear.

Environmental Considerations:

  • Ensure that the lubricants used are suitable for the harsh and remote environments in which many turbines operate, enhancing reliability and efficiency.

Blade and Electrical Component Care

Blade Maintenance:

  • Inspect for Damage: Regularly check blades for signs of fatigue, erosion, or damage from lightning and overloading. Immediate attention to these issues can significantly extend blade life.
  • Repair and Paint: Address any cracks, corrosion, and paint chips promptly to prevent further deterioration and maintain optimal performance.
  • Heat Treatment for Warping: If a blade appears bent, use a heat gun or blow dryer to carefully heat the blade until it is very hot, then reshape as needed without melting the material. If the blade appears bent in hard shape, you might need to order replacement.

Electrical Component Maintenance:

  • Connection Checks: Ensure all electrical connections are clean and tightly secured to prevent power losses and potential hazards.
  • Cable Integrity: Avoid using solid or undersized cables for the turbine’s power cords. Opt for appropriately sized, flexible cables to ensure efficient power transmission and reduce the risk of heat damage.
  • Monitoring Sounds and Vibrations: A slight hum from the turbine is normal, but severe shaking or vibration indicates installation issues, such as blades being installed backwards.

General Tips:

Troubleshooting Common Issues

Understanding and addressing common wind turbine issues is crucial to minimize downtime and repair costs. Here are some key troubleshooting steps:

  • Voltage and Power Output Checks:
    • DC Voltage Test: Always disconnect the turbine from the battery bank and/or charge controller before testing the DC voltage.
    • Using Tools: Employ a DC voltmeter and/or ammeter on the DC side of the rectifier to check for variable voltage.
    • Battery Charging: Charge a battery only if the turbine’s output is higher than the battery’s current voltage.
  • Structural and Environmental Considerations:
  • Mechanical and Wear Issues:

Professional Maintenance and When to Seek Help

When to Hire a Professional:

  • Installation and Major Repairs: Hiring a professional installer, especially for initial setup and major repairs, is crucial for ensuring safety and compliance with local regulations. Professional installers are often licensed electricians who can handle the complex electrical components of wind turbines.

Benefits of Professional Maintenance:

  • Extended Lifespan: Proper installation and routine professional maintenance can significantly extend the lifespan of your home wind turbine, potentially beyond 20 years.
  • Efficiency and Safety: Regular professional check-ups help maintain the efficiency of the turbine and ensure all safety protocols are followed to prevent accidents and breakdowns.


Maintaining a home wind turbine is pivotal to harnessing wind energy efficiently and sustainably, ensuring not only the extension of the turbine’s lifespan but also maximizing its performance through thorough inspections, routine care, and prompt repairs.
