This study investigated application of photovoltaic (PV) panels for office building. Bandung, Indonesia is chosen as case study due to its hot and humid climate. To conduct this study, first, site selection was evaluated, followed by load evaluation using standard requirement for energy-efficient office building. Then, design and size of the system was defined. Feasibility of this study was evaluated from technical and economic indicators, i.e. energy delivered, energy export and import to the grid, yearly savings, and payback period. Simulation of this study was performed with various scenarios on the design electricity load. This study shows that solar PV panels are feasible to be installed in flat roofs and western façade. With 365 m2 of solar panel in total, it can generate 66 MWh electricity per year. If PV provide electricity for lighting inside the building, the payback period is 12 years. This payback period become faster, i.e. 6.24 years, if all the electricity is sold to the grid.
