“…International Energy Agency announced a 4600 GW installation for photovoltaic (PV) and a corresponding 16% electricity generation for the world 76 . The temperature of the PV module is thought to be one of the critical issues to affect the electricity generation during operation of PV modules 77‐80 . It was reported that 1°C increase in temperature resulted in up to 0.5% reduction in efficiency of electricity generation for PV modules 81 .…”

Summary Latent heat thermal energy storage is essential for a broad range of multidisciplinary thermal applications, due to its capability of keeping a relative constant temperature during thermal energy storage/release. The aspect ratio (AR) and installation angle (tilted angle) for a latent heat energy storage tank play important roles in addressing the issue of thermal energy storage/release efficiency. In this work, the coupled effects of tank aspect ratio and tilted angle upon melting phase change were both experimentally and numerically investigated. Wide range of tank aspect ratios from 0.1 to 8.0 was studied with respect to four representative tilted angles (0°, 30°, 60°, and 90°). The detailed features of melting front propagation, temperature distribution, and free convection development in the melt phase were quantified. Results indicated that melting heat transfer was markedly affected by the tilted angle, regardless of tank aspect ratio. However, the fastest melting occurred at different tilted angles, if different tank aspect ratios were considered. With AR < 1.0, the highest melting rate was found at 0° inclination. As for AR > 2.0, the fastest melting was achieved at an inclination of 60°.

“…The fluid motion can enhance the transfer of heat to the PV surface. In recent years, extensive studies on PV coolers were conducted (see Table 1 ) [ [5] , [6] , [7] , [8] , [9] ]. Generally, the PV enhancers are made of stainless steel, aluminum, copper or other metals that have good thermal conductivity for heat transfer enhancement.…”

“…On the other hand, the economic feasibility assessment for PV enhancers can be performed using the PV enhancer cost effectiveness factor, F CE , which is an important parameter that is needed to be taken into account when designing an enhancer (reflector/cooler) for the PV 33 . This parameter states if the designed reflector/ cooler has added a sufficient power to the PV as compared to its cost or getting additional PV is better.…”

“…This parameter states if the designed reflector/ cooler has added a sufficient power to the PV as compared to its cost or getting additional PV is better. F CE was denoted as 33 where P PV,out is the gained power from a PV without an enhancer and P PVCE,out is the gained power from a PV with an enhancer. Y and Z are the cost of one watt of PV power and the cost of the enhancer, respectively.…”

The use of a reflector can increase the solar radiation on the photovoltaic module (PV) surface, whereby the energy output can be improved. However, the economic feasibility may need to be considered too. This study is conducted, for the first time, due to the lack of studies regarding the economic feasibility assessment of implementing reflectors under the Malaysian meteorological conditions. The outcome will give information about the suitability for implementing a PV reflector in Malaysia through an experimental setup at a sewage treatment site, for two months in 2022. The Malaysian meteorological data, which include daily solar radiation, ambient temperature and wind velocity, were collected to study the output energy, efficiency and the economic perspective of a PV. In February 2022, the PV was operating without a reflector and the averaged values for the monthly solar radiation, ambient temperature and wind velocity were 539.9 MJ/m2, 28.4 °C and 2.2 m/s, respectively, which resulted in an output energy of 106.43 kWh. On the other hand, for April 2022, the PV was operating with a reflector. With the respective averaged input parameters 544.98 MJ/m2, 28.9 °C and 1.51 m/s, the output energy was 121.94 kWh. It is thus shown that the PV with a reflector increases the PV’s output energy by 14.57%. Also, it is shown that the cost-effective factor value is 0.955 which means that the PV reflector is economically feasible to be implemented under the Malaysian meteorological conditions. Hence, extensive research should be conducted to improve the performance of PV reflectors. The findings of this paper maybe useful for researchers and/or manufacturers of PV reflectors.
