الملخص

خصائص العواكس تتأثر سلبا بالظروف المناخية للصحراء القاسية وبالتالي أداء المنظومات يقل. هذه الورقة تشخص تأثير نوعين مختلفين من الرمال المتحركة نوع A و B من ليبيا على الأداء والسلامة للعواكس الشمسية. العينات أخذت من مناطق مناسبة لتركيب محطات القدرة الشمسية. فهي مختلفة في حجم الحبيبات والتركيب الكيميائي: نوع A بحجم بتراوح من 355.0-025.0 ملم و النوع B بحجم 479.0-124.0ملم. النتائج المتحصل عليها بإستخدام نفاث الرمال تشير إلى أن الرمل نوع A له تأثير أكثر من النوع B لأن صغر حبيبات النوع A ساهم في انتشارها على مساحة أكبر من العاكس. كما لوحظ في مدى الدراسة أن تغيير السرعة له تأثير أكبر من تغيير كميات الرمل. بعد تنظيف الأسطح، الانعكاسية انخفضت إلى 2.2 % و خشونة السطح ازدادت بحوالي 1 ميكروميتر في حالة كتلة 5.0 جرام عند سرعة 27 متر/ث. في حالة كتلة 2 جرام وسرعة 21 متر/ث الخشونة وجدت 3 ميكرومتر
