Abakiriya bamwe bazabaza impamvu kubyara amashanyarazi ya pv yanjye ya pv bitameze nkukwezi gushize iyo urumuri rukomeye mugihe cyizuba kandi igihe cyumucyo kikaba kirekire?
Nibisanzwe.Reka ngusobanurire: ntabwo aruko urumuri rwiza, niko urwego rwamashanyarazi rwa pv.Ibi ni ukubera ko ingufu za pv sisitemu igenwa nibintu byinshi, ntabwo ari urumuri gusa.
Impamvu itaziguye ni ubushyuhe!
Ubushyuhe bwo hejuru buzagira ingaruka ku mirasire y'izuba, kandi bizanagira ingaruka ku mikorere ya inverter.
Ubushyuhe bwo hejuru yubushyuhe bwizuba buri hagati ya -0.38 ~ 0.44% / ℃, bivuze ko iyo ubushyuhe buzamutse, ingufu z'amashanyarazi akomoka ku mirasire y'izuba zizagabanuka.Mu nyigisho, niba ubushyuhe buzamutse kuri 1 ° C, amashanyarazi ya sitasiyo yamashanyarazi izagabanukaho 0.5%.
Kurugero, 275W izuba ryizuba, ubushyuhe bwumwimerere bwa pv paneli ni 25 ° C, nyuma, kuri buri 1 ° C kwiyongera, ingufu z'amashanyarazi zigabanuka kuri 1.1W.Kubwibyo, mubidukikije bifite urumuri rwiza, kubyara ingufu biziyongera, ariko ubushyuhe bwo hejuru buterwa numucyo mwiza bizahagarika burundu amashanyarazi yatewe numucyo mwiza.
Amashanyarazi ya pv amashanyarazi ni menshi cyane mugihe cyizuba n'itumba, kuko ubushyuhe burakwiriye muriki gihe, ikirere n'ibicu biroroshye, ibiboneka ni byinshi, urumuri rw'izuba rwinjira cyane, kandi hari imvura nke.Cyane cyane mu gihe cyizuba, nigihe cyiza cyumwaka kuri pv amashanyarazi kubyara amashanyarazi.
