Abstract: This study compared the postharvest storage potentials of a solar-powered cool room and an off-grid metal-in-wall evaporative coolant. Temperature drop and relative humidity (RH) increase were used to assess the performance of cooling systems. The metal-in-wall evaporative coolant's cooling efficiency was measured. Tomato (UTC variety), Orange (Dan Benue variety) and Carrot (Orange Chantenay) were procured from the international fruits market in Duste, Jigawa State, Nigeria. The products were sorted and stored in three different storage conditions: room temperature (RT), solar powered cool room (SCR), and wall-in-wall evaporative coolant. Mass loss, color, firmness, total soluble solids and titratable acids, carotenoids, vitamin C, marketability percentage, and rate of nutrient degradation were among the quality characteristics assessed. The temperature was lowered to 17.24 °C by the metal-in-wall evaporative coolant, which was far lower than the room temperature (29.19 °C). Evaporative coolant's relative humidity rose from 69.84 to 83.91% while its average cooling efficiency was 60.79%. The average temperature and relative humidity of the solar-powered cool room were 10.45 °C and 86%, respectively. Fruit quality was significantly (p
