“…Ouédraogo et al examined the temperature reliance of efficiencies of individual energetic process and complete conversion efficiencies of a Si polycrystalline PV cell in the temperature range 10-50 °C (Ouédraogo, Zouma, Ouédraogo, Guissou, & Bathiébo, 2021). Empirical studies of the effect of using combined phase change materials (PCM) on the thermal behaviour and electrical performance of a PV panel were conducted (Senthil Kumar, Ashwin Kumar, Gowtham, Hari Selva Kumar, & Hari Sudhan, 2021). A study proposes a novel technique for estimating the electrical efficiency of PV modules as a function of the solar radiation, the temperature of the cooling fluid, and the solar incidence angle (Ventura, Tina, Gagliano, & Aneli, 2021).…”

This study conducts optimum tilt angle and orientation of a standalone c-Si monocrystalline solar photovoltaic (PV) system deploying PVsyst software. The site of the hypothesized solar PV system is at 9, Mountain Rise, Berea, Durban, South Africa. This work presents values of tilt and azimuth angles and battery operating temperature that support optimal solar PV system performance. The range of angles considered for tilt and azimuth for a fixed PV panel mounting is 0° to 90° and -100° to 100°, respectively. Based on the report obtained from PVsyst design and simulation software, this study finds that: the highest available energy, specific energy, used energy, solar fraction, and lowest loss were recorded at tilt 40° and Azimuth 0°. Further, the longest battery service life was attained at an operating temperature between -2 °C to 20 °C. Hence, 40° and 0° are the optimum tilt and Azimuth angles, respectively while running the storage system at a temperature, not more than 20 °C..

“…The output power achieved was above that of the conventional PV module for 230 min, with a maximum increment of 11.50% and an average increment of 7.28% under the experimental conditions. Others, such as Kumar et al [24], used nanoPCMs to increase the efficiency. The authors achieve a PV panel electrical performance enhancement of up to 4.3%.…”

Photovoltaic modules during sunny days can reach temperatures 35 °C above the ambient temperature, which strongly influences their performance and electrical efficiency as power losses can be up to −0.65%/°C. To minimize and control the PV panel temperature, the scientific community has proposed different strategies and innovative approaches, one of them through passive cooling with phase change materials (PCM). However, further investigation, including the effects of geometric shape, insulation, phase change temperature, ambient temperature, and solar radiation on the PV module power output and efficiency, needs further optimization and research. Therefore, the current work aims to investigate several system configurations and different PCMs (RT42, RT31, and RT25) and compare the system with and without insulation through computational fluid dynamic (CFD) tools. The final goal is to optimise and control the temperature of PV modules and evaluate their system efficiency and energy generation. The results showed that compared with a rectangular shape of the PCM container, the trapezoid-one exhibits a considerably better cooling performance with a negligible variation of the PV temperature, even when the melting temperature of the PCM was lower than the average ambient temperature. Moreover, the study showed that having insulation in the PCM container increases the amount of PCM needed, compared with no insulation case, and the increased amount depends on the PCM type. The newly proposed PV/PCM system configuration shows an efficiency and power generation enhancement of 17% and 14.6%, respectively, at peak times.

We humans find solutions for every problem around us. Taking an environmental problem for water scarcity we have come up with a traditional idea but a bit modified. We have used solar distillation as the basic concept and developed a single slope single basin solar still (SSSBSS) where we have used a storage material that is rarely used for this process and have carried out the research work in it. The experimental study is carried for a single slope single basin solar still (SSSBSS) under two cases (i) SSSBSS (ii) SSSBSS with zeolite crystals as storage materials. The still was made of galvanized iron (GI) and the sides were insulated with polystyrene. It has a basin area of 1 m2. Bore water of Coimbatore which is a bit salty was taken as the feed water. The test was carried out at Kuniyamuthur, Coimbatore during 10th, 11th, 12th of February 2021. Even though it was winter, the output was average. By the comparison using zeolite crystals, the efficiency was doubled compared to the first case.
