| چکیده | ||
| گرد و غبار میتواند با ایجاد آسیبهای فیزیکی، تضعیف تابش رسیده و افزایش درجه حرارت سبب کاهش بازده یک آرایهی فتوولتائیک شود. تمیزکاری آرایهها درگیر مسائلی مانند اتلاف آب، انرژی و زمان است. یک وسیله مکانیکی کارآمد میتواند محیط بزرگی را در زمانی به مراتب کمتر از نیروی انسانی تمیز نماید. در تحقیق حاضر ساخت و مطالعهی عملکرد یک ماشین تمیزکننده مکانیکی بررسی شد. آزمایشهایی با دو عامل نسبت سرعت خطی معادل برس به سکوی تمیزکننده و نوع شوینده، هرکدام در سه سطح، در قالب طرح کامل تصادفی و سه تکرار انجام گردید. ارزیابیها نشان داد اثر عامل نسبت سرعت بر حذف گرد و غبار پنل در سطح 5 درصد معنیدار است؛ از طرفی اثر هر دو عامل آزمایش، در سطح 5 درصد بر افزایش توان معنیدار بود. نتایج نشان داد ماشین تمیزکننده میتواند با کاهش غلظت گرد و غبار، توان هر پنل 280واتی را تا 40وات و بازده را تا 4درصد افزایش دهد. | ||

| چکیده [English] | ||
| Dust deposition on the photovoltaic (PV) arrays surface may cause physical damages, weakens the sun's radiation, and increases the panel temperature that results in the reduction of the electrical efficiency of the panel. PV array cleaning is engaged with issues such as water and energy consumption, and long operating time. An efficient mechanical cleaner improves the cleaning operations compared to the manual operation. In this study, development of a mechanical cleaning machine for photovoltaic arrays surface was carried out. The machine was evaluated using two factors including: the equivalent speed ratio of the brush to the cleaning platform, and the type of detergent at three levels, respectively. The tests were arranged at completely randomized design with three replications. The results showed that the effect of equivalent speed ratio of the brush to the cleaning platform on dust removal was significant (p < 0.05). Also, the effect of all studied factors on output power was significant (p < 0.05). It was revealed that the cleaning machine can increase the amount of power in each 280-Watt panel by up to 40 Watt and the efficiency up to 4%. | ||
