Kev tsim hluav taws xob photovoltaic tau dhau los ua ntau dua thoob plaws ntiaj teb, thiab cov khoom siv hluav taws xob hauv tsev tau maj mam dhau los ua cov cuab yeej tseem ceeb tshaj plaws rau kev tswj hwm lub zog hauv tsev. Tab sis ntau tsev neeg muaj teeb meem los txiav txim siab npaum li cas lub zog khaws cia: 5kWh, 10kWh, lossis 20kWh? Dab tsi ntawm kev siv fais fab tuaj yeem sib txawv ntawm lub zog cia tuav? Dab tsi yog qhov laj thawj tom qab suav cov peev txheej?
Qhov loj ntawm lub ru tsev hnub ci, lub zog siv los ntawm tsev neeg, thiab cov haujlwm niaj hnub ntawm cov neeg nyob ntawd yuav tsum tau coj mus rau hauv tus account thaum txiav txim siab loj npaum li cas lub zog cia hauv tsev yuav tsum yog. Qhov tseem ceeb tshaj plaws uas yuav tsum tau xav txog thaum ua kev suav suav nrog hauv qab no.
1. Kev siv hluav taws xob txhua hnub (kWh)
Qhov no yog qhov kev suav ua raws li. Koj daim nqi hluav taws xob yuav qhia koj tias koj siv zog npaum li cas txhua lub hlis. Koj tuaj yeem hloov tus lej ntawd mus rau tus nqi txhua hnub.
Piv txwv li:
Kev siv ib hlis: 450 kWh
Nruab nrab ib hnub: txog 15 kWh
2. Cov khoom tseem ceeb thaum siv lub zog thaub qab
Yog tias lub zog thaub qab tseem ceeb, xav seb koj xav tau hluav taws xob ntau npaum li cas kom koj cov khoom siv tseem ceeb tshaj plaws ua haujlwm thaum muaj hluav taws xob.

3. Roj teeb qhov tob ntawm qhov tso tawm (DOD)
Feem ntau, cov roj teeb lithium cia koj siv 90% ntawm lawv cov nqi.
Rated peev lub sij hawm DOD sib npaug usable peev.
Lub roj teeb uas muaj peev xwm ntawm 10 kWh feem ntau muaj 8 mus rau 9 kWh ntawm lub zog muaj txiaj ntsig.
4. Hnub ci PV tso zis
Thaum nruab hnub, cov hnub ci vaj huam sib luag tuaj yeem them cov roj teeb hauv tsev nrog lawv, uas txhais tau hais tias lub roj teeb tsis tas yuav loj npaum li.
Piv txwv li:
Kev xav tau ntawm tsev: 12-15 kWh ib hnub twg
Hnub ci tsim: 8-12 kWh / hnub; pom zoo cia loj: 5-10 kWh
2. Koj puas yuav mus nrog 5kWh, 10kWh, lossis 20kWh?
Qhov ntau thiab tsawg ua haujlwm zoo dua rau ntau hom tsev. Ntawm no yog ib qho kev sib faib muaj txiaj ntsig:
1. 5kWh Cia-Rau Me Loads lossis Basic Backup
A 5Kwh Chaw nres tsheb fais fabyog qhov zoo rau cov neeg uas tsuas xav tau lub zog thaub qab yooj yim lossis xav tau lub kaw lus cia yooj yim pib nrog. Qhov loj me no tuaj yeem:
Khaws lub tub yees, teeb, router, thiab hluav taws xob rau thaum muaj hluav taws xob luv luv.
Pab cov tsev uas txuag hluav taws xob los ntawm kev ua me me
Ua rau lub tsev solar panels zoo dua ntawm kev siv lawv tus kheej lub zog
Pom zoo rau:
6-10 kWh ib hnub twg
Chav tsev lossis tsev me me hauv nroog
Cov neeg uas xav tau kev nkag pheej yig - theem cia
2. 10kWh Cia-Qhov Kev Xaiv Zoo Tshaj Plaws rau Tsev Niaj Hnub No
Ib qhov system zoo ib yam li ibZog Generator Cia 10kwyog lub peev xwm loj tshaj plaws rau cov tsev nyob ib puag ncig.
Pros:
suav nrog feem ntau qhov chaw nyob 'kev siv hluav taws xob yav tsaus ntuj
Ua haujlwm nrog cua txias, tub yees, kev lom zem, thiab teeb
Pom qhov sib npaug ntawm tus nqi, kev ua tau zoo, thiab kev cia siab
Zoo rau cov tsev nrog lub hnub ci uas siv 5 mus rau 10 kW ntawm lub zog
Pom zoo rau:
Kev siv txhua hnub: 10 mus rau 20 kWh
Peb - chav pw
Cov neeg uas xav ua tus kheej ntau dua - txaus thiab ruaj khov
3. 20kWh Cia: Rau Cov Tsev Loj, Hnyav Loads, lossis Zog Kev ywj pheej
Lub roj teeb 20kWh yog qhov zoo rau tsev neeg, tsev loj, lossis cov neeg uas xav ua kom muaj zog tag nrho- ywj siab.
Cov xwm txheej zoo sib xws:
