A solar vapour compression refrigeration system was designed for preserve the fishes in the boat for cholachal atmospheric conditions. Now a days fisheries using ice bar for preserve the fishes. By using solar refrigeration system can reduce the weight of ice bar and fuel consumption. Intensity and relative humidity are the performance affecting factors of solar refrigeration system. The various affecting factors were analysed due to the change of relative humidity at the seashore. The solar energy is derived by active solar technique. Solar panel is the essential component to generate the electricity from the sun. Solar panels reduce the pollution levels of the atmosphere. Due to solar refrigeration effect we can enhance the quality of fishing and reduce the fuel consumption.
