Building Integrated Photovoltaic for Rooftop and Facade Application in Indonesia

Abstract

Building sector is one of the biggest energy consumption along with residential, transportations and industrials. Building Integrated Photovoltaic (BIPV) can be an alternative to reduce energy consumption in the building and to secure the energy reserves. This study investigates the application of BIPV on the rooftop and facade of a high-rise building in Jakarta. Here, both technical and economic feasibility study are outlined. We employed the Sunny Web Design software and econometric spreadsheet program to calculate the energy generation and required specifications. BIPV rooftop produces greater energy yield compared to BIPV facade. This is because more radiation can be captured by BIPV rooftop on optimum azimuth and tilt angle. The BIPV reduce 5.97% of energy consumption. From the economic side, the total project cost and revenue of BIPV application is, respectively, 11.4 million USD and 1.2 million USD. This study can be broadened to develop BIPV in Indonesia.
