“…Passive cooling systems does not require any power which makes those more popular avenue for research [15]. Commonly used passive cooling techniques rely on thermosiphon driven air flow [16], capillary action based water flow or evaporation [17] and, heat absorption by phase change materials (PCM). Currently use of PCM as heat absorber and temperature regulator is the most reliable and economical method for the cooling of PV panels.…”

Solar photovoltaic (PV) panels are commonly and widely employed source of renewable power generation. Nonetheless, they suffer from very inferior poor light to energy conversion efficiency. This drawback is aggravated further by 0.02% for every Kelvin rise in solar cell temperature. This paper presents a modelling work on PV cooling techniques through phase change material layer integration on rear PV surface. The PCM layer can absorb the excess heat generated in the panel. Making a composite of highly conductive nanomaterial and this PCM as a layer will boost the heat transfer and maintain PV temperatures close to optimum. Vaseline (Petrolatum or soft paraffin) was selected as the PCM due to easy availability. Graphene nanomaterial was the thermal conductivity enhancer. The cooling effect of the PCM nanocomposite was tested at three different front surface temperature. It was found that addition of PCM layer brings the cooling effect at PV front. This effect further enhances on the addition of PCM nanocomposite layer.

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.

Photovoltaic panels nowadays are considered one of the most important methods for generating electricity directly from the sun as a green energy resource. The photovoltaic cells convert about 20% of solar energy to electric power, and the rest is converted to heat that increases the cells temperature. The photovoltaic performance decreases by about 0.4%–0.5% for each 1°C increase in cell temperature. This article studies the effect of using a novel cooling design to cool floating photovoltaic panels with natural cold water from natural sources. ANSYS has been used to conduct a series of simulations under different boundary conditions like solar radiation, ambient temperature, and cooling water temperature at Duhok Dam Reservoir, KRI. The results of the proposed cooling module showed a significant increase in efficiency (1.26%–2.49%) and power performance (17.76–36.81W) and a significant increase in power (6.43%–14.89%) compared to the non-cooled module. Thus, using an active cooling method for floating panels could be a typical option to boost the output of the solar panels. The results of this research have outperformed other research, with a power increase rate of about 14.1%.
