Energy storage system is important to use electricity effectively from PV solar cell system. One big problem is how to choose business model for setting of Energy storage system. For effective use of energy from PV solar cell and economical use, it is important to select appropriate parameter for setting and compare their cost. In this study, we aim to understand each setting for Energy storage system and calculate cost for each business model to optimize parameter setting. Three business model we tested in this study was Self consumption, Peak shaving and Peak shifting for 4 seasons. We built the simulator by Matlab and find the best parameter to reduce peak at highest mean hour for each month. From results of simulation and calculation, it is found that Peak shaving is best parameter for most seasons, but calculation method from another approach is needed for more detail discussion
