Hnub ci photovoltaic module yog tsim los ntawm lub hnub ci vaj huam sib luag, them nyiaj xws li, inverter thiab roj teeb; Hnub ci dc fais fab tshuab tsis suav nrog inverter. Txhawm rau ua kom lub hnub ci hluav taws xob tsim hluav taws xob tuaj yeem muab lub zog txaus rau kev thauj khoom, nws yog ib qho tsim nyog yuav tsum xaiv txhua yam khoom tsim nyog raws li lub zog ntawm cov khoom siv hluav taws xob. Siv 100W tso zis hluav taws xob thiab siv rau 6 teev hauv ib hnub ua piv txwv los qhia txog txoj kev suav:
1. Ua ntej, watt-teev noj ib hnub twg (xws li inverter poob) yuav tsum tau xam: yog tias qhov kev hloov pauv ntawm lub inverter yog 90%, ces thaum lub hwj chim tso zis yog 100W, qhov tiag tiag yuav tsum tau tso zis hwj chim yuav tsum yog 100W / 90% = 111 W; Yog tias siv 5 teev hauv ib hnub, kev siv hluav taws xob yog 111W * 5 teev = 555Wh.
2. Kev suav cov hnub ci vaj huam sib luag: raws li lub hnub ci hnub ci lub sij hawm ntawm 6 teev, cov zis hluav taws xob ntawm hnub ci vaj huam sib luag yuav tsum yog 555Wh / 6h / 70% = 130W, coj mus rau hauv tus account qhov kev them nqi thiab kev poob hauv cov txheej txheem them. Ntawm qhov ntawd, 70 feem pua yog lub zog tiag tiag siv los ntawm lub hnub ci vaj huam sib luag thaum lub sijhawm them nyiaj.
