Okulandelayo ukwethulwa kwentambo yekhwalithi ephezulu ye-Dc Photovoltaic, ngethemba lokukusiza ukuthi uyiqonde kangcono. Izintambo ze-photovoltaic ze-DC ziyizingxenye ezibalulekile zezinhlelo ze-PV, ezihlinzeka ngoxhumo oludingekayo lukagesi ukuze kunikwe amandla ukukhiqiza okusebenzayo nokuthembekile kwamandla elanga. Ukukhetha okufanele, ukufakwa, nokugcinwa kwalezi zintambo kubalulekile ukuze kuqinisekiswe ukuphepha, ukusebenza, nokuphila isikhathi eside kwesistimu yonke yamandla elanga.
