The objective of this paper is to evaluate the performance of the hydrophobic coatings and detergent cleaning & antistatic protection for photovoltaic solar panels in semi-arid weather conditions in Benguerir Morocco. Various coating and cleaning strategies were tested on five photovoltaic (PV) systems with the same PV panels and electrical configurations. The first PV system (uncleaned) was not subject to any coatings or cleaning solutions. The second PV system (Water Cleaned) was periodically cleaned with raw water. The third PV system: solar wash protects (SWP) made use of a cleaning solution. The fourth:D solar defender (DSS) and fifth: industrial glass protect (IGP) PV systems each had a unique combination of the two hydrophobic coatings. The results demonstrated that after 9 months of operation, in the first 3 months (cleaning period) the average efficiency gain of the coated PV panels is around 10% compared to the reference system. Whereas in the non-cleaning period after 6 months of exposure, the efficiency gain is around 5%. After the outdoor exposure period, the cumulative energy gain of the coated systems compared to the water-cleaned reference reaches an average of 3%. It has been found that the SWP used 50% less water to clean the PV panels than the system cleaned without a cleaning solution, which made the panels harder to clean. The SWP is more successful at dust removal during the dry season (August-February) with low rain rates. However, during the rainy season (March-April), IGP outperformed SWP and DSD, with a small difference in PV performance. This study demonstrates the significance of using new cleaning strategies such as anti-soling coatings in dry areas to enhance the performance of photovoltaic systems, which may be useful for investors, researchers, and engineers interested in grid-connected photovoltaic and self-cleaning technology.
本文的目的是评估摩洛哥本盖里半干旱气候条件下光伏太阳能板的疏水涂层以及洗涤剂清洁和抗静电保护的性能。在五个具有相同光伏板和电气配置的光伏（PV）系统上测试了各种涂层和清洁策略。第一个光伏系统（未清洁）未使用任何涂层或清洁溶液。第二个光伏系统（水清洁）定期用原水清洗。第三个光伏系统：太阳能清洗保护（SWP）使用了一种清洁溶液。第四个：D太阳能防护剂（DSS）和第五个：工业玻璃保护（IGP）光伏系统各自有两种疏水涂层的独特组合。结果表明，运行9个月后，在最初3个月（清洁期），与参考系统相比，涂覆光伏板的平均效率增益约为10%。而在暴露6个月后的非清洁期，效率增益约为5%。在户外暴露期之后，与水清洁参考系统相比，涂覆系统的累计能量增益平均达到3%。已发现，与未使用清洁溶液清洁的系统相比，SWP清洁光伏板的用水量减少了50%，这使得面板更难清洁。在旱季（8月至2月）降雨率较低时，SWP在除尘方面更成功。然而，在雨季（3月至4月），IGP的表现优于SWP和DSD，光伏性能有微小差异。本研究证明了在干旱地区使用诸如防污涂层等新清洁策略以提高光伏系统性能的重要性，这可能对有兴趣于并网光伏和自清洁技术的投资者、研究人员和工程师有用。
