Qhov tseem ceeb, nws yog "tag nrho-hauv-ib tus neeg saib xyuas lub zog" hauv photovoltaic (hnub ci) + lub zog cia (roj teeb) system - tshwj xeeb tsim los tswj koj peb qhov tseem ceeb hluav taws xob xav tau. Yooj yim hais, nws ua peb yam:
Nws hloov lub "lub hnub ci hluav taws xob" tsim los ntawm lub hnub ci vaj huam sib luag (uas peb tsis tuaj yeem siv ncaj qha) mus rau hauv hluav taws xob tsis tu ncua uas tuaj yeem siv hauv koj lub tsev qhov hluav taws xob, rau tej yam xws li them koj lub xov tooj, khiav lub tshuab cua txias, lossis lub zog lub tub yees;
Yog tias lub hnub ci vaj huam sib luag tsim hluav taws xob ntau dua thaum nruab hnub tshaj qhov koj siv (piv txwv li, thaum cov neeg laus nyob hauv chaw ua haujlwm thiab cov menyuam yaus nyob hauv tsev kawm ntawv, thiab tsis muaj leej twg siv hluav taws xob hauv tsev), nws khaws cov hluav taws xob ntau dhau ntawm lub roj teeb, xws li khaws cov dej ntau dhau rau hauv lub thoob, siv thaum hmo ntuj lossis hnub huab cua;
Nws kuj tseem ua haujlwm nrog rau "daim phiaj hluav taws xob" uas koj them rau: thaum daim phiaj hluav taws xob muaj, nws tseem ceeb siv lub hnub ci dawb ua ntej, thiab tsuas yog siv lub zog hluav taws xob thaum xav tau; Yog tias daim phiaj dheev poob qis (piv txwv li, vim muaj cua daj cua dub ua rau cov kab hluav taws xob), nws cia li hloov mus rau "roj teeb lub zog," tiv thaiv cov khoom siv tseem ceeb xws li cov tub yees thiab cov pa oxygen concentrators los ntawm kev poob zog.
Hauv ntej, nws tsis yog ib qho - lub hom phiaj cov cuab yeej, tab sis yog ib qho kev tswj hwm koj "lub hnub ci zog, lub zog khaws cia, thiab lub zog hluav taws xob," kom ntseeg tau tias koj muaj hluav taws xob ntseeg tau thiab txuag koj nyiaj.
