Mazkur tadqiqotda chang va ifloslanishning quyosh panellarining samaradorligiga ta’siri eksperimental jihatdan o‘rganildi. Quyosh batareyalari (photovoltaic panellar) atmosferadagi chang zarrachalarining to‘planishi natijasida yorug‘lik oqimining kamayishi va natijada elektr energiyasi ishlab chiqarish ko‘rsatkichlarining pasayishi muammosiga duch keladi. Tadqiqot O‘zbekistonning janubiy quruq iqlim sharoitida o‘tkazilib, turli darajadagi changlanish (0 g/m², 5 g/m², 15 g/m²) sharoitida panellarning kuchlanish, tok va chiqish quvvat ko‘rsatkichlari o‘lchandi. O‘lchov natijalariga ko‘ra, chang qatlami 15 g/m² ga yetganda quyosh paneli samaradorligi o‘rtacha 40% gacha kamaygani aniqlandi. Harorat va nurlanish sharoitlari (E = 850 W/m², T = 28 °C) doimiy saqlangan holda, changning optik singdirish ta’siri asosiy yo‘qotish omili sifatida qayd etildi. Tadqiqot natijalari shuni ko‘rsatadiki, quyosh panellarida muntazam tozalash tizimini joriy etish yoki gidrofobik himoya qoplamalarini qo‘llash samaradorlikni barqaror ushlab turishda muhim omil hisoblanadi. Ushbu ish natijalari quyosh energiyasi tizimlarining ekspluatatsiya ishonchliligini oshirish hamda O‘zbekistonning cho‘l va yarim cho‘l hududlarida amaliyotga tatbiq etish uchun ilmiy asos bo‘la oladi.
