Teb Chaws Asmeskas tsev neeg PV ntxiv rau lub zog cia kev lag luam tau nce!

Tam sim no, hybrid PV ntxiv rau cov qauv khaws cia yog nyob rau hauv Teb Chaws Asmeskas kev lag luam PV, nrog lub sij hawm cia ntev dua thiab kev loj hlob ntawm cov roj teeb cia / PV muaj peev xwm sib piv.

Lub Lawrence Berkeley National Laboratory's (LNBL) daim ntawv tshaj tawm hnub ci txhua xyoo sau tseg tias qhov loj ntawm lub hnub ci vaj huam sib luag nyob hauv Asmeskas tseem loj hlob ntxiv, thaum qhov feem pua ​​​​ntawm cov chaw khaws cia ntxiv, raws li kev txheeb xyuas qhov teeb meem ua ntej rau thawj ib nrab ntawm 2021-2022. Txawm hais tias qhov poob qis me ntsis, tus nqi nruab nrab nruab nrab rau txhua hom PV tej yaam num tau poob dua.

Tus nqi nruab nrab ntawm 7.

Kev loj hlob sai hauv thaj chaw PV

Daim ntawv tshaj tawm qhia txog cov ncauj lus tseem ceeb hauv Asmeskas kev lag luam PV, nrog LBNL hais tias qhov loj ntawm thaj chaw PV systems tseem loj hlob, mus txog qhov nruab nrab ntawm 7.0kW hauv 2021, thiab qhov loj ntawm cov tshuab tsis yog tsev neeg muaj. theem tawm. Feem ntau [cov tshuab tsis yog tsev neeg] kuj me me, nrog tus nqi nruab nrab ntawm tsuas yog 33kW hauv xyoo 2021, nrog thaj tsam 20 feem pua ​​​​loj dua 150kW thiab qhov nruab nrab ntawm ib ncig ntawm 250kW rau tag nrho cov tshuab tsis yog tsev neeg.

Lub chaw soj nstuam txhais cov kab ke uas tsis yog tsev neeg raws li qhov loj ntawm av-mounted fais fab nroj tsuag mus txog 5MW.

Lub caij no, cov khoom siv hluav taws xob theem hluav taws xob, xws li microinverters lossis DC optimisers, txuas ntxiv nce lawv cov kev sib koom hauv tag nrho cov qauv, suav txog 94 feem pua ​​​​ntawm cov tshuab hauv tsev hauv 2021, 81 feem pua ​​​​ntawm cov me me (<100kw) non-household="" systems="" and="" 36%="" of="" large="" non-household="" systems="">

Hais txog kev taug qab cov tshuab, nyob ib ncig ntawm 46 feem pua ​​​​ntawm tag nrho cov tshuab tsis yog tsev loj uas tau teeb tsa hauv 2021 yuav yog cov nroj tsuag hauv av, tsuas yog 12 feem pua ​​​​uas muaj peev xwm taug qab. Hauv kev sib piv, 13 feem pua ​​​​ntawm cov tshuab me me uas tsis yog tsev neeg thiab 2 feem pua ​​​​ntawm cov kab ke hauv tsev yog cov haujlwm hauv av, nrog rau qhov tsis txaus ntseeg ntawm kev taug qab, daim ntawv tshaj tawm qhia.

LBNL txheeb xyuas cov ntaub ntawv ntawm tus nqi teeb tsa uas them los ntawm cov tswv system ua ntej tau txais kev txhawb siab. Qhov no yog raws li ib feem ntawm cov ntaub ntawv loj dua, uas feem ntau suav nrog cov tshuab PV nyob ib leeg.

Trends nyob rau hauv qhov system loj nyob rau lub sij hawm

Nqe nkhaus

Daim ntawv tshaj tawm qhia tias tus nqi nruab nrab ntawm qhov project hauv Asmeskas tau poob los ntawm qhov nruab nrab ntawm ib ncig ntawm {{0}}.4c/W ib xyoos, tab sis tus nqi ntawm tus nqi txo tau qis dua txij li xyoo 2013, nrog rau kev txo nqi txhua xyoo. nyob ib ncig ntawm 0.1c-0.2c/W txij thaum ntawd los.

Nyob rau hauv cov nqe lus ntawm kev nce nqi-hloov tiag tiag, tus nqi nruab nrab rau tag nrho peb lub sector tau poob los ntawm 0.1c-0.2c/W ntawm 2020 thiab 2021. cov nqi ntxiv tau nce siab rau cov nqi dhau los ntawm ob xyoo, tab sis txawm li cas los xij, cov ntaub ntawv ua ntej rau thawj ib nrab ntawm 2022 qhia tias tus nqi nruab nrab nruab nrab tiag tiag rau cov tsev nyob tsis hloov pauv ntawm ib nrab xyoo 2021.

Txawm li cas los xij, muaj kev pom zoo dav dav hauv kev lag luam uas cov khoom lag luam tsis txwv yuav ua rau muaj kev ntxhov siab rau tus nqi, tab sis qhov no yuav tsis cuam tshuam tag nrho cov nqi ntawm cov phiaj xwm teeb tsa, thiab qee qhov ntawm cov nqi tiag tiag, hauv kev hloov pauv nyiaj txiag rau cov ntaub ntawv nqi. Hauv cov ntsiab lus nominal, tus nqi nruab nrab rau tsev neeg thiab cov tshuab tsis yog tsev neeg loj tau nce siab hauv thawj ib nrab xyoo 2022.

Ib yam li ntawd, muaj qhov sib txawv ntawm qhov sib txawv ntawm cov xeev hauv Teb Chaws Asmeskas, nrog ib nrab ntawm lub xeev qhia qhov nce ntawm cov nqi tsev neeg nruab nrab hauv 2020-2021, thaum feem ntau ntawm lub xeev qhia qhov txo qis hauv cov nqi tsis yog tsev neeg.

Nyob rau hauv 2021, tus nqi nruab nrab ntawm PV system nrog roj teeb cia yog $0.6-1.6/W siab dua ib qho PV system nyob ib leeg nyob rau peb ntu. siv ntau qhov kev ntsuam xyuas rov qab, LBNL kwv yees tias yog tias lub roj teeb 5kW tau nruab nrog 10-15kWh ntawm kev cia, tus nqi khaws cia ntxiv rau tsev neeg PV yog $1.9/W.

"Raws li cov tsev neeg ib txwm muaj PV thiab qhov ntau thiab tsawg, qhov no sib npaug rau qhov muaj peev xwm nce nqi ntawm lub zog cia ntawm kwv yees li $ 1,200 / kWh, uas zoo ib yam nrog cov nqi nruab nrab hauv tsev neeg lub zog khaws cia tau tshaj tawm los ntawm California Txoj Haujlwm Pabcuam Tib Neeg Tus Kheej."

Cov nqi tau poob qis txij li xyoo 2000. Raws li xyoo 2013, cov nqi tau nce qib

Hnub ci-cia co-qhov chaw

Xyoo no Daim Ntawv Qhia Txog Hnub Ci Tracker tseem suav nrog kev sib tham txog cov ncauj lus ntawm kev sib koom ua ke ntawm hnub ci cia, suav nrog cov ntsiab lus ntawm cov roj teeb cia ntxiv rau cov nqi thiab qhov system sizing.

Daim ntawv tshaj tawm pom tias tus nqi ntxiv rau cov roj teeb cia hauv thaj chaw nyob tau nce tsis tu ncua, nce mus txog 10 feem pua ​​​​ntawm cov ntaub ntawv piv txwv hauv 2021. Cov nqi ntxiv hauv cov khoom tsis yog hauv tsev tau qis dua, hloov pauv thiab nce ntau xyoo. , nce mus txog 4.9 feem pua ​​​​ntawm tag nrho cov tshuab nruab hauv xyoo 2021.

Txawm li cas los xij, cov nqi ntxiv no tsis sib npaug thoob plaws Tebchaws Meskas, nrog rau kev nce ntxiv ntawm cov nqi ntxiv feem ntau cuam tshuam txog kev nce qib hauv ob peb lub xeev, xws li California. Hawaii muaj tus nqi ntxiv siab tshaj plaws ntawm ib lub xeev (93 feem pua ​​​​rau cov tsev neeg thiab 59 feem pua ​​​​rau cov tsev neeg tsis yog tsev neeg hauv 2021), thiab cov xwm txheej huab cua huab cua xws li cua daj cua dub Uri, uas tau ua phem rau Texas xyoo tas los, tau ua rau muaj kev xav tau ntau ntxiv. co-nyob roj teeb lub zog cia systems (BESS).

Sij hawm dhau mus, cov kab ke hauv tsev nrog lub zog khaws cia txuas ntxiv mus rau qhov loj me me, nrog kwv yees li 42 feem pua ​​​​ntawm cov tshuab nrog tsawg kawg 10kW roj teeb tau teeb tsa hauv xyoo 2021, tab sis cov tshuab tsis yog tsev neeg nrog lub zog cia ua me thiab me. Yuav luag ib nrab ntawm tag nrho cov uas tsis yog-tsev cov tshuab nrog kev cia nruab rau hauv 2021 yuav muaj roj teeb me dua 10kW.

LBNL hais tias qhov no yog vim "nce kev lees paub los ntawm cov neeg siv khoom me me ntawm cov ntawv thov uas tsis yog xav tau kev tswj hwm tus nqi".
