On analyzing the data, the month of February seems to have the greatest demand for storage. To effectively design a storage system, the system has to be designed for the day which requires the maximum storage. The maximum storage required by the system is for 411 kWh units of energy at site. Water as a sensible Thermal Energy Storage (TES) medium is the most commonly used and commercially available storage. Large standardized as well as custom made water tanks with appropriate insulation are available in market. However, the size restriction might make water a less feasible option. Phase Change Materials (PCMs) are being researched as an alternative to water as TES medium. PCMs is a developing technology, however some PCMs are commercially available in the market. Zalba et al. (2003) reviews all the potential PCMs, which can be used as energy storage materials. The author further tabulates the PCM’s which are commercially available. From the commercially Savings in percentage
