Profitability assessment of PV rooftop implementation for prosumer under net metering scheme in Indonesia

This study conducts an analysis of photovoltaic (PV) rooftop potential for domestic application in Indonesia. In this study, the potential solar energy is simulated by using IES VE software coupled with a Monte Carlo probabilistic approach to account for the variability of solar energy. Economic analysis is undertaken based on the calculated solar energy using an exceedance probability of 90%. The economic analysis is developed under the latest net metering scheme as regulated by Regulation of Minister of Energy and Mineral Resources in Indonesia. The study shows that despite a mismatch between the peak solar generation and the peak demand for power that rooftop PV is still cost effective. Using the latest net metering scheme, the costumer is benefiting from a PV rooftop investment despite the significant reduction of export energy price compared to the previous net metering regulation.
