The solar-powered ice maker was developed in Kemujan, Karimunjawa island, Indonesia. It was powered by 6.66 kWp of solar PV, 19.2 kVAh battery storage, as well as 2 kW of solar ice maker machine, and connected into the utility grid (PLN). Solar energy is applied in this system to minimize utility grid consumption, which is produced by a diesel generator. The hierarchy of the energy supply was PV, batteries, and PLN, respectively. The system is capable to produce 180 kg of ice per production cycle, with a production cycle duration of roughly 20–27 hours. On cloudy days, the renewable energy penetration is around 15–19%. The COP of the ice maker machine is 1.02 and 1.45 for production cycle with ambient brine water temperature and low brine water temperature, respectively.
