The Phase change material based high temperature solar energy storage device is used to produce electricity by means of sterling engine or process heating application. The energy storage is taken place by means of exploitation of latent heat of fusion of material stored inside the tank system. The method is mainly chosen because its capacity to producing high energy density and store energy can be successfully extracted with small variation in temperature every time, which adds major advantage in the entire processing. The justification on selection made for phase change material is discussed; the layer of insulating material is applied over system under thermal consideration analysis and optimization. The application of layer depicts heat loss to surrounding and thus helps further major temperature. The paper shows comparison between results, one obtained via experimental set up, observation noting, calculation performed and other by computer simulation, where the process is centric about computerized model formed and performance evaluation measure of real time prototype system.
