Hukumar Lantarki ta Duniya (IEC) ta fito da IEC 60364-7-712: 2017 don "Lowananan shigarwar lantarki - Sashe na 7-712: Bukatun don shigarwa na musamman ko wurare - Tsarin samar da wutar lantarki na hasken rana photovoltaic (PV)".

Bayani: “IEC 60364-7-712: 2017 ya shafi shigar da lantarki na tsarin PV da aka yi niyyar samar da duka ko sashin shigarwa. Kayan aikin shigarwa na PV, kamar kowane kayan kayan aiki, ana magance su ne kawai gwargwadon zaɓin sa da aikace -aikacen sa a cikin shigarwa.

"

Matsayi:

Wannan bangare na IEC 60364 ya shafi shigarwar lantarki na tsarin PV wanda aka yi niyya don wadatar da duka ko ɓangaren shigarwar.

Kayan aikin shigarwar PV, kamar kowane abu na kayan aiki, ana aiki dashi ne kawai har zuwa yadda zaɓinsa da aikace-aikacen sa a cikin kayan aikin ya shafi.

Girkawar PV tana farawa ne daga tsarin PV ko saitin nau'ikan PV da aka haɗa a jeri tare da wayoyin su, wanda mai ƙirar PV ya samar, har zuwa shigarwar mai amfani ko wurin samar da kayan amfani (ma'anar haɗin kai ɗaya).
