This research aims to experimentally improve the overall efficiency of solar photovoltaic (PV) panels by coating them with hydrophobic SiO2 nanomaterial. Also, an accurate mathematical model was used to estimate the parameters of the PV panel, which is a non-linear optimization problem. Based on the experimental data and using the particle swarm optimization (PSO) algorithm, the optimal five parameters of a single diode model of a PV panel were determined in this study. This experimental work was conducted and carried out in the Renewable Energy Laboratory of Assiut University, Egypt. A comparative analysis was completed for three identical solar PV panels; the first panel was coated with hydrophobic SiO2 nanomaterial, so it was considered to be a self-cleaning panel; the second panel was uncoated and cleaned manually on a daily basis; and the third panel was kept dusty all the time through the experimental investigation, and was used as a reference. Experimentally, the output power of the PV panels was monitored for each panel in this study. Also, the anti-static and anti-reflection effects of coating solar PV panels with hydrophobic SiO2 nanomaterial were investigated experimentally. According to the obtained experimental results, it was found that the use of SiO2 coating for PV panels results in the better performance of the PV panels. The overall efficiency of the coated panel increased by 15% and 5%, compared to the dusty panel and the uncoated panel which was manually cleaned daily, respectively.

疏水性SiO2纳米材料提高太阳能光伏板能源效率的实验研究。

这项研究旨在通过用疏水性SiO 2纳米材料涂覆太阳能光伏(PV)面板,以实验方式提高其整体效率。而且,使用了精确的数学模型来估算PV面板的参数,这是一个非线性优化问题。根据实验数据并使用粒子群优化(PSO)算法,本研究确定了光伏面板的单个二极管模型的最佳五个参数。这项实验工作是在埃及Assiut大学的可再生能源实验室中进行的。对三个相同的太阳能光伏电池板进行了比较分析。第一块面板涂有疏水性SiO 2纳米材料,因此被认为是一种自清洁面板;第二个面板每天不涂涂层并手动清洁;第三块面板在实验研究中一直保持灰尘,并作为参考。实验上,在这项研究中对每个面板的PV面板的输出功率进行了监控。此外,还研究了用疏水性SiO 2纳米材料涂覆太阳能光伏板的抗静电和抗反射作用。根据获得的实验结果,发现使用SiO 2PV板的涂层可提高PV板的性能。与每天手动清洁的多尘板和无涂层板相比,涂层板的整体效率分别提高了15%和5%。
