This study proposes a new model operation for an intermediate thermal storage (ITS) tank solar water heater system. It combines passive-charge active-discharge (PCAD) in single tank, potentially reducing the number of components system and improving net energy balance. The charge process is done by heating material using electric heater, which also suitable direct photovoltaic heating. temperature profile stabilized this stage shows close plateau line solid-liquid transition, indicating steady phase transition takes place. minimizes deviation between solid/liquid region, advantageous determining protocol. For discharge process, working fluid circulates from mantle side continues to inner resulting two-consecutive allows harness stored heat up 72.8%. achieved material, has better solidification mechanism. Thus, proposed PCAD able meet criteria ITS requires exchange during charge/discharge stage. finding demonstrates that simplification achievable. implication can be used as fundamental basis developing systems, including photovoltaic-heating systems where taken alternative instead electricity.
