Amanye amakhasimende azobuza ukuthi kungani ukuphehlwa kukagesi kwesiteshi sami sikagesi se-pv kungekuningi njengasezinyangeni ezimbalwa ezedlule lapho ukukhanya kunamandla ehlobo futhi isikhathi sokukhanya sisande kangaka?
Lokhu kujwayelekile kakhulu.Ake ngikuchazele: akukhona ukuthi ukukhanya okungcono, kuyanda ukukhiqizwa kwamandla kwesiteshi samandla se-pv.Lokhu kungenxa yokuthi ukuphuma kwamandla esistimu ye-pv kunqunywa izici eziningi, hhayi nje izimo zokukhanya.
Isizathu esiqondile kakhulu izinga lokushisa!
Imvelo yokushisa ephezulu izoba nomthelela kuphaneli yelanga, futhi izophinde ibe nomthelela ekusebenzeni kahle kwe-inverter.
Izinga lokushisa eliphakeme kakhulu lamaphaneli elanga ngokuvamile liphakathi kuka -0.38~0.44%/℃, okusho ukuthi lapho izinga lokushisa likhuphuka, ukukhiqizwa kwamandla kagesi welanga kuzokwehla. Ngokombono, uma izinga lokushisa likhuphuka ngo-1°C, ukukhiqiza amandla wesiteshi samandla e-photovoltaic sizokwehla ngo-0.5%.
Isibonelo, iphaneli yelanga engu-275W, izinga lokushisa langempela lephaneli ye-pv lingu-25°C, ngemva, kukho konke ukukhuphuka okungu-1°C, ukukhiqizwa kwamandla kuncipha ngo-1.1W.Ngakho-ke, endaweni enezimo ezingcono zokukhanya, ukukhiqizwa kwamandla kuzokwanda, kodwa izinga lokushisa eliphezulu elibangelwa ukukhanya okuhle lizosusa ngokuphelele ukukhiqizwa kwamandla okubangelwa ukukhanya okuhle.
Ukukhiqizwa kwamandla kwesiteshi samandla se-pv kuphezulu kakhulu entwasahlobo nasekwindla, ngoba izinga lokushisa lifanelekile ngalesi sikhathi, umoya namafu mancane, ukubonakala kuphezulu, ukungena kokukhanya kwelanga kunamandla, futhi kunemvula encane.Ikakhulukazi ekwindla, isikhathi esihle kakhulu sonyaka sokuthi isiteshi sikagesi se-pv sikhiqize ugesi.
