The result shows that the net energy discharge cost of Case 6 (with three parallel channels and two different sensible heat storage modules in each channel) is highest (62.26 USD/kW-h). Case 3 (six concrete connected in the series arrangement) yields high storage and discharge energy densities at a low cost of 1.18 USD/kW-h.
One of the important aspects of designing a suitable PCM-based solar water heater is proper selection of PCM. The important properties that need to be considered for selection of PCM are as follows. 1. High latent heat of phase change which leads to large energy storage density. 2.

The PCM is placed in a storage tank, and the HTF flows through channels into a heat exchanger. The PCM is macroencapsulated in PCM modules that are located in the storage container—the HTF flows around the capsules. The PCM is a component of the HTF and increases its capacity to store the heat—called " PCM slurry.
The energy storage modules tested in this study were modeled after parallel-plate heat exchangers frequently used in commercial and domestic hot water applications [38], [14]. This allowed comparison to past studies and enables module fabrication with off-the-shelf aluminum and NiTi sheet material.
