Simulation of impact azimuth angle on specific energy output of a fixed mounting rooftop PV system in Jakarta, Indonesia

Abstract

One of the key performances of a PV system is specific energy output, which is calculated based on energy output compared to the input solar irradiation under operating conditions. The specific energy output is affected by many factors, mainly by the amount of solar irradiation received by the module. This work presents the simulation of impact azimuth angle on specific energy output by the fixed mounting rooftop PV System in Jakarta, Indonesia. Simulation is carried out using SolarGIS PVPlanner by varying roof orientation, which is correlated with module azimuth angle. The tilted of the module is assumed 30°, fixed with the common residential roof tilt in Jakarta, Indonesia. It is found that the highest annual specific energy output is about 1,243 kWh/kWp produced by module orientation of Northeast, while the lowest is produced by module facing South with specific energy output about 1,098 kWh/kWp.
