【 摘 要 】

Solar energy is a renewable energy source, from that electricity can be generated. In response to increasing electrical energy costs, large number of thermal storage technology has been introduced by various researchers. The latent heat storage type system got a good response for the storage of solar energy in various applications. In the present work, an attempt has been made to showcase the utilization of solar energy to produce electrical energy using paraffin wax as phase change material and Peltier modules. In this experiment 5kg of paraffin wax has been used in a cylindrical absorber to store the thermal energy. The experimental results show that the time average minimum and maximum temperature of paraffin wax varies from 31.56°C to 94.24 °C in day1, 29.59 °C to 88.12 °C in day2, 32.02 °C to 88.36 C in day3 and also the minimum and maximum voltage generated by the peltier module varies from to 0.07V to 0.507V in day 1, 0.063V to 0.428V in day2, 0.072V to 0.428V in day3 of experimentation.
