The main components that comprise typical microhydro schemes are electromechanical equipments, civil structures, and energy distribution systems [4]. An optimum operational design, smart selection of equipment, and reduced professional consultation input can lower the overall cost[5– 7]. It is important to pay attention to actions to reduce the whole microhydro cost because it is always the main concern for small communities especially in rural areas. In order to minimize the overall cost,microhydro system must be in the optimal operation and component selection. Furthermore, the microhydro must be reliable,robust,and manageable with minimum technical knowledge by local communities.
