Reliability of small wind farms

The reliability of small wind farms is still very low. As the manufacturer says, even if you invest in a truly high-quality wind farm, it won't be effective for 20 years. During this time, you will be forced to repair it and replace defective parts. If you still decide to install a small wind farm, make sure it fails, when and how often. Considering all of the above information, it is most convenient to install a low power wind turbine on the tower. This will greatly facilitate service and repair work. Removing equipment from separate towers will greatly increase equipment operating costs Since we have been exposed to services, it should be mentioned that in windy areas, wind farms can operate for 7,000 hours or more per year. If it is a car with a speed of 50 km / h, it will pass 350,000 km per year. This means that regardless of the manufacturer's recommendations, devices with such working resources have an unavoidable annual service, which requires at least inspection of all screws and lubrication components.
