“…There are many reviews available about the integration of latent heat energy storage material in the solar still [63,64], covering various types of latent heat energy storage materials such as paraffin, lauric acid, glauber's salt and stearic acid [24,27]. Among these, paraffin is most widely used owing to its low cost and favourable thermo-physical and chemical properties [26,63,65,66].…”

Solar power is considered as the most essential renewable energy in human life, particularly for daily activities. The application of solar water heater is significantly able to reduce the electric load of water heating so that this method is indirectly able to save energy needs. The biggest challenge is increasing the energy density of warm water storage. The best storage medium is paraffin, but it is constrained by the low thermal conductivity of the paraffin and also the wrapping media. This study focuses on efforts to improve thermal conductivity of paraffin as a heat storage medium by using nickel mixture at a ratio (volume) of 10 - 50%. Samples of paraffin and nickel paraffin mixture are inserted into the wrapper of aluminum 6063 material and then tested for heat absorption and release process. The best heat absorption is shown by the sample with the most nickel content, while in the heat release process the best performing sample is shown with a nickel mixture between 20–40%. These results are directly related to the power rate of each sample. The results of this study can be used as a reference for increasing the thermal capacity of warm water storage from solar water heaters.

The study investigates the impact of Phase Change Material (PCM) and nano Phase Change Materials (NPCM) on solar still performance. PCM and a blend of NPCM are placed within 12 copper tubes submerged in 1 mm of water to enhance productivity. Thermal performance is assessed across four major scenarios with a fixed water level of 1 mm in the basin. These scenarios include the conventional still, equipped with 12 empty copper rods and 142 g of PCM in each tube, as well as stills with NPCM Samples 1 and 2. Sample 1 contains 0.75% nanoparticle concentration plus 142 g of PCM in the first 6 tubes, while Sample 2 features 2% nanoparticle concentration plus 142 g of PCM in the subsequent 6 tubes. Aluminum oxide (Al2O3) nanoparticles ranging in size from 20 to 30 nm are utilized, with paraffin wax (PW) serving as the latent heat storage (LHS) medium due to its 62 °C melting temperature. The experiments are conducted under the local weather conditions of Vaddeswaram, Vijayawada, India (Latitude-80.6480 °E, Longitude-16.5062 °N). A differential scanning calorimeter (DSC) is utilized to examine the thermal properties, including the melting point and latent heat fusion, of the NPCM compositions. Results demonstrate that the addition of nanoparticles enhances both the specific heat capacity and latent heat of fusion (LHF) in PCM through several mechanisms, including facilitating nucleation, improving energy absorption during phase change, and modifying crystallization behavior within the phase change material. Productivity and efficiency measurements reveal significant improvements: case 1 achieves 2.66 units of daily production and 46.23% efficiency, while cases 2, 3, and 4 yield 3.17, 3.58, and 4.27 units of daily production, respectively. Notably, the utilization of NPCM results in a 60.37% increase overall productivity and a 68.29% improvement in overall efficiency.
