Badania eksperymentalne wpływu cześciowego zacienienia modułu fotowoltaicznego na generowaną moc elektryczną
PublicationZacienienie wpływa znacząco na parametry pracy modułu fotowoltaicznego. Kiedy część modułu jest zacieniona, niektóre ogniwa są spolaryzowane w kierunku zaporowym i zachowują się jak obciążenie, a nie jak generator. Miękkie źródła zacienienia, takie jak konary drzew, elementy konstrukcyjne budynku czy kominy, które rozpraszają i załamują światło, znacząco ograniczają ilość promieniowania, docierającego do powierzchni modułu, podczas...
