Solar energy has been well known for some applications, one of them is the solar for productive use. Solar ice maker is one of the implementations of solar energy in productive use. In Indonesia, there are a lot of coastline areas with most people work in fishery aspect. Solar ice maker business has high potential to implement in these rural fishermen areas. The feasibility of solar ice maker was studied in some areas of Indonesia which evaluated based on the techno-economical evaluation. Techno evaluation was performed by analyzing the solar power prediction performance, renewable energy penetration, in-operated emission produced, and the system performance; while, the economical evaluation was seen from the NPV, IRR, the initial cost. The real scale testing was conducted in Kemujan’s solar ice maker system in Karimunjawa Island. The result showed that it produced NPV and IRR IDR IDR 198,217,345.80 and 5.45% respectively with the cycle use batter scheme, for 25 years of lifetime. The ice maker machine performance has COP 1.02 and 1.45 for high brine water temperature and low brine water temperature respectively. The duration of ice production in one production cycle is 27 hours 10 minutes for the high brine water temperature, and 20 hours 45 minutes for low brine water temperature. The study also designed the solar ice maker with some different scenarios performed for other areas, which include in Java Island and Outside Java Island to evaluate the best scenario. In Java Island, the case study employed Kampung Mariuk, Sukabumi. While outside Java Island, the design is located in Tanjungbatu, East Borneo. Both locations utilized the same ice maker machine; the brine water cooling and direct cooling machine. Based on scenarios rank, solar ice maker system in Java Island is better using PV On grid system. While in outside Java Island is feasible to use the PV On grid system with battery storage or diesel generator as backup energy plant.
