The main problem of small wind turbines is their maintenance needs. They require a lot of care and it’s much more fun to build the wind turbine than to maintain or fix it.
To our knowledge maintenance failures and their consequences are known only locally and rarely shared. Quantitative feedback hopefully will help to facilitate the maintenance operation.
The report can be seen here :
The raw data can be seen here : Raw data survey.
The online tools used (lime survey) made the causes of the problem hard or sometimes impossible to determinate.
More data crossing are needed in order to figure out some failures pattern.If you are willing to help,get in contact with us.
