The Effect of Staggered porous fins on the performance of Photovoltaic panel in Baghdad

The temperature of a photovoltaic (PV) panel has a negative effect on the generated power. As the solar irradiance that falls on the PV increases, the operating PV temperature rises, which leads to a decrease in electrical efficiency. Therefore, there arises a need to introduce a cooling system to minimize PV temperature. In this study, the simple passive cooling method of extending its surfaces with fins was used to reduce the PV temperature. Different numbers of longitudinal aluminum fins were attached to the bottom surface of a PV panel and their effects were examined under realistic weather conditions for Baghdad, Iraq. Results show that the use of the passive cooling method under natural convection will be more effective in reducing PV temperature before solar noon than after solar noon. The maximum power enhancement was about 2.5 W and occurred at solar noon when using 10 aluminum fins. The peak efficiency value of the PV panel with fin cooling was about 15.3% against 14% for the unfinned PV panel.

“…It is critical that societies shift to accessible, renewable energy resources and maintain a balance between sustainability and economic benefits [1]. The use of renewable energy sources for daily energy needs is rapidly growing, and solar energy is an essential source that has a variety of uses, including direct/indirect heating and photovoltaic power generation [2,3]. The solar air heater (SAH) collector is essential for solar energy conservation and by heating the surrounding air can be used for a variety of purposes, including heating, cooling, and drying [4].…”

Artificial roughness applied to a Solar Air Heater (SAH) absorber plate is a popular technique for increasing its total thermal efficiency (ηt−th). In this paper, the influence of geometrical parameters of V-down ribs attached below the corrugated absorbing plate of a SAH on the ηt−th was examined. The impacts of key roughness parameters, including relative pitch p/e (6–12), relative height e/D (0.019–0.043), angles of attack α (30–75°), and Re (1000–20,000), were examined under real weather conditions. The SAH ηt−th roughened by V-down ribs was predicted using an in-house developed conjugate heat-transfer numerical model. The maximum SAH ηt−th was shown to be 78.8% as predicted under the steady-state conditions of Re = 20,000, solar irradiance G = 1000 W/m2, p/e = 8, e/D = 0.043, and α = 60. The result was 15.7% greater efficiency compared to the default smooth surface. Under real weather conditions, the ηt−th of the roughened SAH with single- and double-glass covers were 17.7 and 20.1%, respectively, which were higher than those of the smooth SAH.

“…Convection heat transfer is particularly significant in many engineering and industrial processes. These include air‐conditioning system, 1,2 fuel cells, 3 thermo‐electrical cooling, 4 and solar system, 5,6 and so forth. Therefore, several researchers have concentrated their efforts on improving this mechanism of heat transfer, and consequently, numerous techniques have been developed during the previous two decades.…”

A recent study compared experimentally the hydraulic and thermal activity of twisted tape inserts for two types, metal foam twisted tape (MFTT) and traditional twisted tape (TTT), in a double pipe heat exchanger. The investigation goal of the innovatively designed MFTT is to enhance the heat transfer process, which provides a higher thermal enhancement factor over those of TTT under the same conditions. Heat transfer activity in terms of Nusselt number (Nu) and Nusselt number ratio (Nu/Nu o ) as the heat exchanger equipped with the proposed MFTT and TTT inserts with various tape-twist ratios (y/W = 3.6, 5.2, and 6.8) are considered over various values of Reynolds numbers (16,300 < Re < 32,500). The results reveal an improvement in heat transfer rate with both MFTT and TTT and this improvement is proportional inversely to the twisted ratio, but the MFTT showed the highest value of heat transfer compared to TTT and clear tube. Also, the Nu of MFTT augments averaged about 175%-230% compared to the TTT depending on the twist ratio and about 275% and 500% over that of the clear tube. At a twist ratio of 3.6, the heat transfer coefficient is recorded at 37% and 45% for MFTT and TTT models,
