Design of Rooftop Photovoltaic System for 30/60- type House in Sukabumi, Indonesia using PVSyst Simulation

Abstract

The rooftop photovoltaic system is one of the renewable energy sources which is pushed by the Indonesian government to use as alternative energy in public and private buildings. But, the use of PV rooftops in small public housing is still low due to the lack of design standards which makes banking and financial institution do not have the interest to make special loan schemes for PV rooftops. This research wants to propose a design standard that is suitable for 30/60-type houses, a small public housing which popular in Indonesia due to the subsidized loan scheme from the government, using PVSyst simulation. The location is set in Ujung Genteng, Sukabumi because it has good solar energy potential (DNI=3.502kWh/m2 per day). The results of this research based on the PVSyst simulation, the PV rooftop design which is suitable for a 30/60-type house is consists of 4 units of 275Wp PV panel, Inverter 450Vac, and 2 units of 12V/200Ah battery.
