Residential Wind Turbines: Maintenance Issues and Cost
Maintenance of a residential wind turbine falls into two categories: preserving the efficiency of the system and ensuring its safe operation. Fortunately, modern turbines have few moving parts and are designed to operate for up to 120,000 hours or roughly 15 years. The estimated cost of annual repairs and maintenance is about 2.5 to 2 percent of the original cost of the system, or about 0.01 cents per kilowatt hour.
