The rise of electric vehicle (EV) deployment in Indonesia urges the development of charging infrastructure. Leveraging renewable source such as solar energy as a source for EV charging can bring an end-to-end EV’s environmental value. EV charging and solar PV plant combined is a complex integration of technology therefore universities as research institutions could be pioneers in developing them. It also brings benefits for universities in increasing their sustainability points. By using simulation tool for solar PV power plant design (PVSyst) the amount of potential electricity generated from the sun is then estimated for an EV charging scheme in universities. The proposed design utilizes LPKEE ITB’s rooftop to acquire 81 kWp in capacity of solar power plant. The solar energy harvested can generate up to 120 MWh of electricity on the first year. From the solar power plant daily production profile, a level 2 EV charging scheme is modeled within 8 hours (8 a.m. – 4 p.m.) for one EV at a time, except between 10 a.m. to 1 p.m. it is possible to charge up to 2 EVs simultaneously. The number of EV could be charged during office hours vary from 5 unit (Hyundai Kona) to 26 unit (Toyota Prius PHEV) depends on its battery capacity. Financial analysis of investment on the solar power plant and EV charging station provides a recommendation for scenario involving RESCO which obtains NPV worth 53 million Rupiah, IRR 15,18%, and PBP in 5,96 years.
