Abstract

The main objective of this paper is to present the techno-economic analysis of an off-grid Photovoltaic system, which prepared to support disaster mitigation scheme in remote areas. As a case study, a regency in Mentawai Island, Sumatera Barat is chosen to represent a remote area in a disaster-prone location. The proposed system capacity is 20 kWp PV system as a single electricity source for medical facility in the island. As a tool in this study, RETScreen software was used to analyze the technical, environmental, and economical feasibility analysis. As a base case scenario, the medical facility was supported by a diesel-fueled generator and the PV system can deliver 10.14 MWh of electricity to load annually. Net annual GHG emission reduction of the system is 19.4 ton of CO2 equivalent. With the total initial cost for the whole PV system at USD 41,380, RETScreen simulation result showed that the equity payback of the project is 6.0 years with IRR of 11.9% hence the project is financially viable.

Abstract

The transition to electric vehicles in Indonesia continues to progress, along with increasing awareness of the importance of reducing emissions and utilizing renewable energy. One of the challenges still faced is the limited infrastructure for charging and battery swapping. This study designed a battery charging system using two 100Wp solar panels connected in parallel to increase the charging current, and a Maximum Power Point Tracking solar charge controller to regulate the input current to the battery. Tests were conducted on three variations of battery capacity, namely one battery (12 Ah), two batteries (24 Ah), and four batteries (48 Ah), to evaluate the efficiency and charging time of the batteries. The results showed that the charging time for each variation ranged from 3 to 6 hours, depending on the number of batteries and solar irradiation conditions. The designed lightweight Public Electric Vehicle Battery Charging System (SPBKLU) proved to be a sustainable emergency solution for battery charging using renewable energy sources.
