Analysis on the Application of PV Technology in Terms of Tranditional Roof House. Case Study: Julang Ngapak Sundanese Traditional Roof Form

Abstract

This study departs from the thought that the implementation of new technology should consider the local context or the concept of “genius loci”. Based on this conception, this study is aimed to investigate whether the implementation of the current technology (here is PV technology) can be in accordance with the initial local traditional architectural form. To accommodate that objective, the roof form of the Sundanese traditional house called “Julang Ngapak”, located in West Java, was studied to analyse its particular orientation, North and South in regards to the solar incident level. The campus building of Bina Nusantara University, located in Jakarta, was selected for the study of PV roof implementation. The method of the study is simulation by applying the EnergyPlus software. There are three types of PV roof which were simulated to investigate the electricity production of the solar cell. The final deliveries of this study are to compare and to analyse the solar irradiance arrive on each type of roof and to define the most appropriate roof form in terms of orientation for implementing the BIPV concept on building particularly in Jakarta region.

Life Cycle Cost Comparison Study of PV and Concrete Rooftop in Jakarta

“…Solar panels with monocrystalline silicone technology was used in the simulation, with the following technical specifications: (1) the watt peak was 240 watts, (2) the efficiency of the module was 21.6%, (3) the temperature coefficient was −0.3%/°K, and (4) the panel dimension was 1580 × 798 × 35 mm which consists of 72 cells. Based on the previous research, to maximize the work of solar panels, the selected roof was flat shaped (flat roof) with 10-degree angle from the horizontal line (see Figure 3) [4].…”
