Performance Analysis of Multi-Oriented Residential Rooftop PV System in Indonesia Towards Net Zero Emission by 2060

Abstract

Performance of 5 kWp Multi-Oriented Photovoltaic (PV) Power Plant installed in one of the houses in Jakarta, Indonesia has been obtained by evaluating the performance of the rooftop PV Power Plant system. To calculate the impact of the system on Net Zero Emissions (NZE), it is necessary to evaluate the performance to determine the quality of the installed system's performance by calculating the Performance Ratio (PR) and the Capacity Factor (CF). The data needed to calculate PR and CF consist of PV array outputs; irradiation that falls on the surface of the array, ambient temperature and PV module temperature. These data were collected for one year from January to December 2022. From the calculation, the system yields 76.07% PR, 11.13% CF, and CO2 emissions reduction was 3,703.63 kg/year. As a comparison and reference, a PR and CF system calculation is carried out with PVSyst software which simulation results can be used to design a PV Power Plant system with the proper orientation both multi and single oriented for optimal performance. The technical quality of a good PV Power Plant system is needed to support the achievement of Indonesia's target towards NZE in 2060. The results of the study show that compared to the system PR, the performance evaluation of the PV Power Plant system based on CF systems is more appropriate to be used as a benchmark because it is more oriented to the output system which is directly proportional to the reduction of CO2 emissions.
