Energy Potential and Economic Feasibility of Rooftop Solar PV on Office Buildings in Makassar City
Analisis Potensi Energi dan Kelayakan Ekonomi PLTS Atap pada Gedung Perkantoran di Kota Makassar
Abstract
Makassar receives high solar irradiation, but rooftop PV adoption on office buildings is still low. This study analysed the energy potential and economic feasibility of rooftop PV on three office buildings with 620–1,450 m2 of usable roof. Energy yield was simulated with PVWatts using a mean irradiation of 5.2 kWh/m2/day. Feasible capacity was 98–230 kWp, producing 131–306 MWh per year, or 18–27% of building consumption. Under the current rooftop PV scheme, NPV was positive, IRR ranged from 11.8% to 13.5%, and payback periods were 7.1–8.3 years. Rooftop PV is technically and economically feasible for office buildings in Makassar.
