Design and Application of PV Rooftop for Grid Feed in Residential House South Lampung

Abstract

This study aims to design a rooftop solar power plant system and analyzing the power output using PVsyst Software. The location for the photovoltaic (PV) installation was carried out in the Way Hui local government housing in South Lampung, Indonesia. The method used in this research is direct measurement at the installation site and system design using software. In this study, energy audits were also carried out from the practitioner's residence. The results of the design are obtained from the software to consider the next process. The simulation results produces system energy in a year as much as 1,712 kWh, specific production 1,114 kWh / kWp / year, PF 0,724, normalized production 3.05 kWh / kWp / day, array losses 0.84 kWh / kWp / day, and system losses of 0.33 kWh / kWp / day.
