Адаптація методу оцінки зваженої ефективності фотоелектричних інверторів до кліматичних та експлуатаційних умов України
Анотація
Розроблено методику визначення регіональних зважених коефіцієнтів ефективності фотоелектричних інверторів на основі даних PVGIS SARAH-3 (2005–2023). Методику застосовано для 19 локацій України, що охоплюють п’ять кліматичних зон. Запропоновано та розраховано національний зважений коефіцієнт корисної дії (ККД) та проведено порівняння з європейським та каліфорнійським зваженими ККД. Встановлено, що розподіл робочих точок інверторів в Україні суттєво відрізняється від закладеного в європейському стандарті оцінки ефективності інверторів. Зокрема, вага домінантної точки навантаження суттєво знижується порівняно з європейською метрикою, а вага точки повного навантаження стає практично нульовою. На практиці це призводить до зміни рейтингу комерційних інверторів та має важливе значення для проєктування фотоелектричних систем в Україні.
Ключові слова: фотоелектричний інвертор, зважена ефективність, коефіцієнт корисної дії, національний зважений ККД, PVGIS, європейська ефективність, каліфорнійська ефективність.
