Experimental Evaluation of Solar Powered Egg Incubator with Integrated Thermal Energy Storage: (Case Study: West Showa Zone Bako District, Ethiopia)

The sun's energy is the best choice for thermal energy generation because it is accessible worldwide and is free to utilize. Poultry egg incubation requires a continuous supply of energy for efficient performance and operation. On-grid power does not reach rural areas in Ethiopia, and even in areas where it is available, electricity may be unreliable or shut off at any time, leading to incubator malfunctions, limited production, and high costs. The utilization of generators increases the operational expenses of incubators, and the natural incubation process by hens yields a very small number of chickens. A solar-powered egg incubator with a thermal energy storage system was constructed, modeled, and tested in this investigation to evaluate its performance. A solar egg incubator was developed using a solar collector with built-in sensible solid heat storage (positioned beneath the absorber plate), a 50-egg capacity incubation chamber, and a control unit. During the incubation period, there is ample sunlight that is converted into the energy required for a solar-powered egg incubator by a flat plate solar collector in the study area. The findings indicated that on the days with the highest solar radiation (629.3w/m2), the average outlet collector temperature was 53°C, while 37°C was achieved on the days with the lowest solar radiation (397.5w/m2). The maximum collector thermal efficiency was determined to be 44.33%. A total of 20 eggs were tested for both fertility and hatchability over a 21-day period in a solar-powered egg incubator. The incubation chamber was maintained within a temperature range of 36.5 to 39.5°C and a relative humidity range of 40 to 75% using a temperature controller (thermostat STC 1000) throughout the incubation period. The percentage of fertile eggs and hatchability were 61.11% and 27.27%, respectively.
