ABSTRACT:
Indonesia has determination to accelerate roof solar photovoltaic (PV) infrastructure in term of green house gas emission reduction target of 29% in 2030 in Indonesia’s National Determined Contribution. Proper orientation and tilt angle of solar PV installation will give optimum energy to meet the infrastructure’s need, but shading (e.g. cloud cover) will reduce energy converted in solar PV system. This study aims to compare orientation and tilt angle of roof integrated solar photovoltaic in tropical areas with high precipitation. The method in this study used REVIT software to simulate the roof with different orientations and tilt angle in the study case of Bogor City, Indonesia. The implementation of designing solar panels as a roof (Building Integrated Photovoltaics) needs consideration particularly in tropical areas with high precipitation. The meteorological condition which is related to cloud cover will significantly affect the performance of solar panels at certain times in the area. The characteristics atmosphere in Bogor area tend to have cloud formation at 1 p.m. It will lead to decreased irradiation absorption during the afternoon period (1 p.m. to 6 p.m.). Based on the simulation results, solar irradiance during morning period is significantly higher by 23.68% than afternoon period. The optimal orientation and tilt angle of roof solar PV in tropical areas with high rainfall tends to have 5⁰ and directed to the East.
