Ambulances are vital to pre-hospital emergency care, yet many in isolated communities lack a full complement of electric powered medical devices. An approach not fully developed in the literature is to provide power to medical equipment in isolated communities is to apply modular solar photovoltaic (PV)-powered direct current (DC) nanogrid systems to provide uninterrupted power supply for mini-mobile clinics or ambulances. This study aims to i) integrate this modular DC nanogrid into ambulances, ii) analyze the estimated loads and iii) optimize the sizes of PV modules and batteries using the physical constraints of the ambulance and simulations with the Solar Alone Multi-Objective Advisor (SAMA) for representative locations in the global north and south (London, Ontario, Canada and Addis Ababa, Ethiopia). The results of this study found the rooftop integrated solar-powered DC nanogrid can supply critical power for the instruments inside the ambulance or mini clinic throughout the day without requiring grid power even with the ambulance moving. In Addis Ababa, a DC nanogrid system with a single 175-Watt (W) PV module and a 2- kilowatt-hour (kWh) battery bank is sufficient to meet an ambulance’s annual energy demand while providing the necessary voltage levels (6 V, 12 V, and 24 V) for onboard medical devices. This alternative PV system offers higher efficiency and reliability, making the proposed solution both sustainable and economically viable for remote healthcare applications.
