This paper presents a study of hybrid solar photovoltaic and micro-hydro system for rural areas of Yogyakarta Special Region. The Yogyakarta region is very potential in developing renewable energy for the supply of electricity, especially in rural areas. Efforts to develop renewable energy is in line with the Indonesian government program that targets until 2025, in Indonesia the electrical system is supplied by power plants by 25% comes from renewable energy. The types of renewable energy that have the greatest potential in Yogyakarta are solar photovoltaic and micro-scale hydro energies. In this study, the potential of micro-hydro power plants was revealed by measuring the irrigation water flow, head, and the output power produced. The potential of solar photovoltaic energy is obtained from solar radiation data for the Yogyakarta region. Data on the potential of the two energy sources is then used to design a hybrid power plant for the needs of a villages electricity supply. To get the appropriate generating capacity, a survey of the villages electrical energy needs is carried out. The results of the design of the generating capacity, the required investment costs, the selling price of electricity, and the payback period are discussed in this paper.
