“…However, no work has been found in the literature where a phase change material has been integrated with a PV and hybrid renewable energy system. Phase change materials have the ability to cool down the PV [25] and store huge amount of energy in a latent form, consequently increasing the PV electrical efficiency [26]. The present study investigates how the integration of a phase change material with a PV panel will affect the optimization of the HRES, which thus has the potential to reduce the cost of energy.…”

The intermittent nature of renewable sources, such as solar and wind, leads to the need for a hybrid renewable energy system (HRES) that can provide uninterrupted and reliable energy to a remote and off-grid location with the use of a biogas generator and battery. In the present study, conventional PV panels have been integrated with phase change material (PCM) for power enhancement. In addition, various configurations (i. PV-Wind-Battery system, ii. PV-PCM-Wind-Battery, iii. PV-Wind-Biogas-Battery and iv. PV-PCM-Wind-Biogas-Battery) have been compared for the hot and humid climatic location of Chennai, India. Optimization has been carried out to minimize the cost of energy and the net present cost has also been computed. It has been found that the integration of PCM with the PV-Wind-Biogas-Battery-based off-grid system results in savings of USD 0.22 million in terms of net present cost and reduces the cost of energy from USD 0.099/kWh to USD 0.094/kWh. Similarly, for another off-grid HRES configuration of PV-Wind-Battery, the integration of PCM results in savings of USD 0.17 million, and reduces the cost of energy from USD 0.12/kWh to USD 0.105/kWh.

“…Latent heat thermal energy storage technology with PCMs is a promising way to improve the utilization rate of renewable energy, and ease the contradiction between energy supply and demand 1–5 . PCMs have many application potentials, such as continuous use of solar energy, waste heat recovery and utilization, cooling of electronics, mobilized thermal energy storage 6–14 . Inorganic hydrated salts PCMs have the advantages of high latent, stable phase change temperature, wide range of phase change temperature, and low price.…”

The main objective of this research is to characterize, via experimental analysis, the effects of thickeners on thermophysical properties of Alum (KAl[SO4]2·12H2O) as phase change material (PCM) for energy storage. Six thickeners, including sodium carboxymethyl cellulose (CMC‐Na), sodium polyacrylate (PAAS), polyacrylamide (PAM), polyvinyl alcohol, xanthan gum (XG) and methylcellulose (MC), are added in Alum. Then the thermophysical properties and the cycle stability are tested and analyzed by step cooling experiment, differential scanning calorimeter, hot disk, scanning electron microscopy, high‐low temperature alternating test chamber, X‐ray diffraction (XRD), and Fourier transform infrared spectrometer (FT‐IR). The results showed that the adding of 2 wt% CMC‐Na, 1 wt% PAAS, 2 wt% PAM, 5 wt% XG, and 1 wt% MC to Alum can effectively reduce the subcooling of Alum while still maintaining the latent heat at a high level. After stability test with 60 melting‐solidification cycles, the results indicate that Alum with 1 wt% MC has the best thermal cycle stability and has the highest latent heat (230 J/g). The latent heat is only 8.1% lower than that of pure Alum after 1 cycle, and 11.1% higher than that of pure Alum after 60 cycles. The XRD, FT‐IR, and thermogravimetry results show that it has good chemical and thermal stability.

“…The system was found to be beneficial even with low-velocity conditions. By integrating micro-fins, PCM and nano-enhanced PCM, Sourav et al (2019) numerically and experimentally studied the effect of passive cooling technique (n-PCM) to lower PV temperature. Luo et al (2017) developed a PV-PCM device using shapestable composite paraffin PCM and found that form-stable composite PCM helps to control PV panels' temperature easily.…”

Photovoltaic (PV) panel, coupled with phase change material (PCM), has attracted broad attention for the panel's thermal management. Despite the higher energy storage capability of PCMs, the main disadvantage is their low thermal conductivity which is compensated to an extent with the nano-enhanced PCMs (NEPCMs). In this study, numerical simulations are carried out to compare the natural convection phenomena and thermal response of PV-NEPCM with simple PV-PCM for various tilt angles. CuO nanoparticles with a 4% volume concentration are selected for NEPCM. The thermal performance of PV-NEPCM at inclinations of 0°, 15°, 30°, and 45\(^\circ\) are compared with a simple PV-PCM system. The average temperature of PV, liquid fraction and thermal energy stored in PCM, the PV efficiency are compared for PV-PCM and PV-NEPCM systems. Results show that the loading of nanoparticles increases the conduction heat transfer inside PCM. It has also been shown that at lower inclinations, the use of NEPCM is more effective due to the dominance of conduction heat transfer. At higher tilt angles, natural convection plays a significant role in the heat transfer mechanism inside PCM. By using NEPCM, the maximum decrease in PV temperature of 1.11\(℃\) and maximum improvement in the liquid fraction (7.6%) are achieved when \({\theta }=0^\circ\) compared to simple PCM. Enhancement of thermal energy stored in PCM increases slightly upon adding nanoparticles, and the highest improvement is obtained for \({\theta }=0^\circ .\) Maximum enhancement of PV efficiency is found to be 1.6% for \({\theta }=0^\circ\) inclination on adding nanoparticles at a fraction of 4 vol.%. Keywords: PV, nano-enhanced PCM, nanoparticles, natural convection, liquid fraction.
