Abstract:
Human activities and climatic elements, including temperature, humidity, and wind speed, have an impact on natural dust deposition. Therefore, this study aims to investigate the effects of wind speed, relative humidity, and ambient temperature on the performance of soiled photovoltaic panels in Al Seeb, Oman. The study was conducted by exposing the solar PV panels to outdoor sunlight for a duration of two months. Parameters such as solar radiation, voltage, current, solar panel temperature, wind speed, relative humidity, and ambient temperature were collected in a short time interval. It was observed that the dust densities of 20.7 g/m2, 27 g/m2, and 41.3 g/m2 resulted in electrical power reductions of 18 %, 33 %, and 40 % for the panels uncleaned for one week, two weeks, and three weeks, respectively. The effect of daily dust resulted in an energy reduction of 14 %. Moreover, dust deposition decreases when the wind speed increases, resulting in a higher power output and vice versa. The higher the humidity, the stronger the dust\'s adhesion to the surface, resulting in more deposition and reduced power output. The maximum power output of 82.3 W was achieved at the wind speed of 10 m/s, 34.9 % relative humidity, and ambient temperature of 38.5 °C.
摘要:
人类活动和气候因素,包括温度,湿度,湿度和风速,对自然粉尘沉积有影响。因此,这项研究旨在研究风速的影响,相对湿度,和环境温度对AlSeeb中污染光伏板性能的影响,阿曼。该研究是通过将太阳能PV板暴露于室外阳光下两个月来进行的。太阳辐射等参数,电压,电流,太阳能电池板温度,风速,相对湿度,在短时间间隔内收集和环境温度。据观察,20.7g/m2,27g/m2和41.3g/m2的粉尘密度导致电力减少18%,33%,一周未清洁的面板占40%,两周,还有三个星期,分别。每日灰尘的影响导致能量减少14%。此外,当风速增加时,灰尘沉积减少,导致更高的功率输出,反之亦然。湿度越高,灰尘对表面的附着力越强,导致更多的沉积和降低的功率输出。在10m/s的风速下实现了82.3W的最大功率输出,34.9%相对湿度,环境温度为38.5°C。
