The using of renewable energy in Indonesia is significantly increasing as fast as the development of its technology and electricity needs, especially in residential area. The office area is one of the biggest electricity consumer. This article discusses the development planning of the Solar Home System (SHS) in office sector, in Special Region of Yogyakarta Province. The development planning has 3 steps such as solar energy calculation, design and system quantity calculation, and the implementation at one site. System design is calculated by the energy potential and electricity loads would be covered. This calculation aims to get the best operation performance of the SHS. The SHS design is used to provide electricity of more than 20 lighting points both inside or outside the building and also is used as back up plan when the public grid is off. The design has power capacity of 1 kW with 24 VDC on its operation voltage at on-grid topograph. The system used 1 kWp of solar panel array, 1 kW of Solar Charge Controller and 1 kW pure sine inverter. The whole components of the system is an appropriate technology by then.
