Lub ntiaj teb tab tom tig mus rau cov khoom siv hluav taws xob tauj dua tshiab, thiab lub hnub ci zog yog ib qho kev xaiv nrov tshaj plaws. Thaum xav txog lub hnub ci fais fab, ib qho ntawm cov kev txiav txim siab tseem ceeb yog seb puas yuav xaiv ib qho ntawm cov kab hluav taws xob los yog off-grid system. Ob leeg muaj lawv qhov zoo thiab qhov tsis zoo, thiab qhov kev xaiv feem ntau nyob ntawm tus kheej qhov xwm txheej.
On-grid solar systems, tseem hu ua grid-tied systems, yog txuas nrog rau daim phiaj hluav taws xob hauv zos. Thaum koj lub hnub ci vaj huam sib luag tsim hluav taws xob ntau dua li qhov koj xav tau, qhov ntau dhau tau rov qab rau hauv daim phiaj. Hloov pauv, thaum koj cov panels tsis tsim txaus (xws li thaum hmo ntuj), koj tuaj yeem kos lub zog ntawm daim phiaj.
Lub ntsiab kom zoo dua ntawm on-grid systems yog lub peev xwm los sib npaug koj lub zog ntau lawm thiab noj. Koj tuaj yeem siv daim phiaj ua ib hom roj teeb, kos lub zog thaum xav tau thiab pub nws rov qab thaum tsis muaj. Qhov no tshem tawm qhov xav tau rau cov roj teeb uas kim heev. Tsis tas li ntawd, ntau lub cheeb tsam muaj cov kev pab cuam metering uas koj tuaj yeem tau txais credit lossis them nyiaj rau lub zog tshaj koj pub rau hauv daim phiaj.
Txawm li cas los xij, qhov teeb meem tseem ceeb ntawm on-grid systems yog tias lawv feem ntau tsis muab hluav taws xob thaum muaj hluav taws xob hluav taws xob. Txij li cov tshuab no tau tsim los kaw thaum muaj kev sib tsoo vim muaj kev nyab xeeb.
Off-grid solar systems tsis txuas nrog rau daim phiaj hluav taws xob thiab yog li yuav tsum muaj peev xwm tsim tau txhua yam hluav taws xob tsim nyog ntawm nws tus kheej. Cov tshuab no xav tau cov roj teeb cia thiab feem ntau ntxiv cov khoom siv hluav taws xob xws li cua lossis diesel generators.
Qhov zoo tshaj plaws ntawm off-grid systems yog ua tiav kev ywj pheej los ntawm daim phiaj siv hluav taws xob. Qhov no ua rau lawv zoo tagnrho rau cov chaw nyob deb tsis muaj kab sib chaws nkag. Lawv kuj muab kev thaj yeeb nyab xeeb hauv cov cheeb tsam uas tsis muaj kev cia siab rau daim phiaj xwm lossis cov nqi hluav taws xob kim.
Txawm li cas los xij, off-grid systems feem ntau yog qhov nyuaj thiab kim vim qhov xav tau ntawm cov roj teeb cia. Lawv kuj yuav tsum tau ua tib zoo tswj xyuas lub zog kom tsis txhob depleting lub roj teeb.
Xaus
Nyob rau hauv xaus, tsis yog ib qho system inherently zoo dua lwm yam; nws nyob ntawm koj tus kheej cov kev xav tau thiab qhov xwm txheej. On-grid systems feem ntau pheej yig dua thiab yooj yim dua tab sis cia siab rau kev sib txuas ntawm kab sib chaws ruaj khov. Off-grid systems muab kev ywj pheej thiab kev ntseeg siab ntawm tus nqi siab dua thiab nyuaj. Nco ntsoov xav txog koj lub zog xav tau, qhov chaw, peev nyiaj, thiab cov cai hauv zos ua ntej txiav txim siab.
