Analysis of difficulties and issues related to the design, construction, transportation, installation and operation of two single-blade wind turbines type as part of a hybrid project to supply electrical energy to an isolated rural community in northern of Colombia are discussed in this paper. This study modeling aerodynamic forces, as well as the analysis the materials used in the construction stage, welding analysis and control systems. This investigation indicates the difficulty to provide stability of civil and mechanical structures of wind turbines without a complete assurance of installation. Most significant issues associated to the development this case including the lack of plan strategy and deficient supervision during construction stages.
