“…The results showed that the PV module with bigger cross-sectional and surface area wasted 155% more heat and produced 10.8% and 4% more power, while also reducing module temperature by 10.6% and increasing module efficiency by 14.5%. The module with round fins dissipated just 27% warmer than the standard module (Amber et al, 2021). This study evaluated the daily and yearly performance of a cooled by air PVT collector with triangle-shaped obstacles to a standard one.…”

The research investigates the use of fins fastened to a solar panel's rear surface for passive cooling. The research compared solar modules with air cooling against modules with connected fins acting as a heat sink. The comparison was based on the former. The research studies the cooling of modules with fins using two different types of air: ventilation air and still air. By comparing the heat transmission by photovoltaic panels with and without fins, the research sought to analyses the effects of the environment and solar radiation on the performance of solar cells. The inquiry was done hypothetically. According to the findings, using fins for cooling reduced cell temperature and improved electrical and thermal efficiency. The estimated performance values of the PVT solar cell obtained by using the COMSOL program and the experimental measurements carried out during the daytime were reasonably in accord. The biggest reduction in cell temperature is (3.7ºC at noon), while the greatest increases in electrical and thermal efficiency are (16.54% and 58.3%, respectively). There is good agreement between experimental and numerical results.

“…At the temperature range of 67 °C-50 °C, PV modules are subject to high thermal stress (Kurtz et al, 2009;Vaillon et al, 2020). The variations in the PV module's temperature are due to cooling under natural wind flow (Dwivedi et al, 2020;Amber et al, 2021).…”

Analysis of various degradations of five years aged mono c-Si, poly c-Si, and thin-film photovoltaic modules from rooftop solar installations in Dhaka’s tropical wet and dry climate conditions

This study evaluates the degradation of mono, poly, and thin-film silicon solar photovoltaic (PV) modules through visual and electrical measurements in Dhaka’s tropical wet and dry climate conditions. For this, several sites of rooftop solar PV installations in Dhaka, aged at least 5 years, were selected for field investigation. A visible inspection for visual degradation followed by experimental testing on various electrical characteristics of the PV modules installed on the rooftop using a portable Seaward I–V Tracer for measuring the electrical degradation was done. The electrical data were used to evaluate the degradation of short circuit current, open circuit voltage, fill factor, and maximum power in the field as compared to the nameplate values. Experimental results showed the varying types of visual degradation types such as visible cracks, snail trails, moisture intrusion, front glass, and discoloration for the investigated PV modules. The degradation of PV modules in terms of short circuit current was 0.7%/year for 85Wp mono c-Si, 7.6%/year for 150Wp poly c-Si, and 9.7%/year for 105Wp silicon thin-film, respectively. We believe this study would guide the maintenance of the solar PV systems installed on Dhaka city’s rooftop buildings.

“…This goal can be achieved by using passive or active cooling elements. 82,99,100 Active cooling approaches and combining PV with thermal systems (PV/T) bring in additional complexity and energy consumption 101,102 whereas passive cooling approaches such as adding heatsink to the rear side of the PV module, 100,103 the use of phasechange materials (PCM), and optical filters are found to be promising. 93,104,105 In 1977, a PCM was suggested as potential thermal storage when integrated with a PV module 106 and patented in 1983.…”
