“…Heat is taken up by cells from the surface and released into the surrounding environment. Active cooling systems rely on external electric power to operate fans or pumps that remove heat from the surface of the panels [27]. Active cooling, which uses active components like fans and pumps, is more effective than passive cooling and has a higher capacity to remove heat from PV panels [16].…”

Due to its widespread availability and inexpensive cost of energy conversion, solar power has become a popular option among renewable energy sources. Among the most complete methods of utilizing copious solar energy is the use of photovoltaic (PV) systems. However, one major obstacle to obtaining the optimal performance of PV technology is the need to maintain ideal operating temperature. Maintaining constant surface temperatures is critical to PV systems’ efficacy. This review looks at the latest developments in PV cooling technologies, including passive, active, and combined cooling methods, and methods for their assessment. As advances in research and innovation progress within this domain, it will be crucial to tackle hurdles like affordability, maintenance demands, and performance in extreme conditions, to enhance the efficiency and widespread use of PV cooling methods. In essence, PV cooling stands as a vital element in the ongoing shift towards sustainable and renewable energy sources.

“…Penggunaan heat sinks multi level pada modul photovoltaic yang diselidiki melalui metode elemen hingga (FEA). Pada validasi CFD dengan perbedaan jarak sirip dan ketebalan dapat ditunjukkan bahwa semakin besar jarak sirip maka semakin rendah suhu rata-rata pada modul photovoltaic dan semakin besar ketebalan sirip hasil simulasi menunjukkan rata-rata suhu modul photovoltaic menjadi rendah [13]. Sistem pendingin dari photovoltaic cell dengan penggunaan pendingin air seperti model radiator pada photovoltaic cell dapat meningkatkan keluaran daya listrik dari photovoltaic cell dan meningkatkan efisiensi dari photovoltaic cell [14].…”

“…The panel temperature differences calculated regarding the base case were 1.49℃ for metal mesh and 3.18℃ for cooling fins. Ahmad et al [24] conducted a numerical simulation to investigate electrical and cooling performance for PV modules by truncated multi-level fin heat sink fin. In their study, it was seen that the proposed fin gives a lower average temperature and higher electrical power for the PV module than the plane fin.…”

An existing PV system is cooled by heat dissipation to air by straight fins arrays attached at the backside of the panels. However, a little average temperature drop has been achieved in the plant. The current research aims to simulate and investigate the low cooling performance experienced in the plant and recommend improved PV cooling by backside installed fins. A CAD model was constructed with CATIA software and imported to ANSYS-Fluent to simulate and investigate the cause of low cooling performance. In addition, cooling performance by 45°, 90°and 135° have been studied. The solar PV panel has 1000-mm-width and 2000-mm-length, whereas the fins' base dimensions are 830-mmwidth, and 1260-mm-length and each fin has 80-mm-height. The reference case study's average temperature measured in the actual site is 46.9℃, while the simulation prediction is 48.4℃. The 3.3% difference suggests that the simulation procedure is sufficient to investigate the other cases. Solar PV is paired with the fins air cooling system, stimulating the PV/T with only a 2.7% difference between the actual measurements and the simulation prediction. The bare panel simulation results predicted the backside temperature to be 13.4℃ above the ambient temperature. The 45° and 90° oriented fins reduced the backside temperature to 4.2℃ and 9.54℃ above the ambient temperature. In contrast, the 135° oriented fins have a negative cooling effect, as they increased the backside temperature to 19.05℃ above the ambient temperature. The analysis suggests that the low-performing cooling in the physical system is due to the bad thermal contact between the array base plate and the panel's backside.
