Cov nqi hluav taws xob txuas ntxiv nce ntxiv, Thiab Kev Txhim Kho Cov Tsev Neeg Photovoltaics hauv Asmeskas Cov Tsev Neeg tau dhau los ua ib qho kev nthuav dav
May 23, 2022
Kev tshawb fawb qhia tau hais tias ntau tus neeg siv hauv tsev hauv Tebchaws Meskas tau nqis peev ntawm $ 15, 000 thiab $ 30, 000 hauv PV systems. Nws puas tsim nyog rau kev nqis peev piv rau kev them nyiaj rau lub tuam txhab hluav taws xob tsis siv hluav taws xob los ntawm PV system?
Thaum yuav ib lub tsev PV system, nws cov lus hais siab yuav ua rau tib neeg xav tias vim li cas lawv thiaj li yuav cov khoom kim heev PV?
Piv nrog rau kev txhim kho PV hauv tsev, cov nqi hluav taws xob them rau lub tuam txhab hluav taws xob tsis zoo li qhov siab. Lub koom haum tshawb fawb tau tshawb xyuas qhov no, ua ntej ntawm tag nrho cov, nws tau tshawb xyuas qhov xwm txheej ntawm kev lag luam tam sim no, yog vim li cas cov neeg siv nruab photovoltaic systems, thiab hluav taws xob ntau npaum li cas lawv xav kom them. Tom qab ntawd nws tshuaj xyuas tus nqi nruab nrab ntawm PV modules thiab tshuaj xyuas kev txhawb siab hauv txhua lub xeev Asmeskas kom nce tus nqi ntawm thaj chaw PV.
Raws li US Energy Information Administration (EIA), txhua tsev neeg siv qhov nruab nrab ntawm 893kWh ntawm hluav taws xob ib hlis, yog li ntawm tus nqi nruab nrab ntawm $0.138/kWh, tus nqi hluav taws xob ib hlis yog kwv yees li $123, piv rau daim nqi hluav taws xob txhua hli rau ib tsev neeg hauv California. rau $229. Kev txheeb cais qhia tau hais tias dhau 20 xyoo dhau los, cov nqi muag khoom hluav taws xob hauv Tebchaws Meskas tau nce 59 feem pua, lossis 2.95 feem pua ntawm ib xyoos. Qhov no txhais tau hais tias nyob rau 20 xyoo tom ntej no, qhov nruab nrab nqi hluav taws xob txhua hli hauv Tebchaws Meskas yuav nce mus txog $ 213, thaum qhov nruab nrab nqi hluav taws xob txhua hli hauv California yuav nce mus txog $ 398.
Qhov ntawd txhais tau hais tias cov tsev neeg Asmeskas yuav them tag nrho $ 39,460 hauv cov nqi hluav taws xob nyob rau 20 xyoo tom ntej raws li cov nqi keeb kwm. California cov tsev neeg yuav them $73,465 hauv cov nqi hluav taws xob nyob rau 20 xyoo tom ntej.
Kev tsim kho kev lag luam tsis ntev los no tau pom tias cov khoom muag tau nce siab, thiab lub zog tsis muaj qhov tshwj xeeb. Yog li cas daim nqi hluav taws xob yuav nyob rau hauv 20 xyoo? Cov nqi no tseem xav tias kev siv hluav taws xob ntawm cov neeg siv hauv tsev yuav nyob zoo li qub rau 20 xyoo, tab sis raws li Asmeskas siv zog ua hluav taws xob hauv tsev, nce cov khoom siv hluav taws xob thiab siv tsheb hluav taws xob, ntau tus neeg siv hauv tsev tuaj yeem xav tias yuav siv hluav taws xob ntau ntxiv hauv cov khoom siv hluav taws xob. yav tom ntej.
Lwm qhov tseem ceeb uas tuaj yeem ua rau cov nqi hluav taws xob ntau dua yog kev hloov khoom dua tshiab. Teb Chaws Asmeskas cov khoom siv hluav taws xob uas ua rau cov neeg siv khoom hauv tsev muaj kev laus thiab xav tau kev txhim kho loj lossis kev kho dua tshiab. Raws li kev kwv yees, $ 500 txhiab daus las yuav raug siv rau hauv kev sib txuas lus los ntawm 2035. Tus nqi $ 50 billion yuav raug xa mus rau cov tsev neeg Asmeskas, uas yuav ua rau nce nqi hluav taws xob.
Cov txiaj ntsig ntawm lub zog thaub qab kuj tseem tuaj yeem nce ntxiv raws sijhawm. Cov hluav taws xob hluav taws xob tau nce ntxiv thoob plaws Asmeskas, thiab Kev Tshawb Fawb Xov Xwm ntawm US Energy Information Administration (EIA) cov ntaub ntawv qhia tau hais tias Asmeskas kev cuam tshuam nrog huab cua hnyav tau nce ob npaug rau 20 xyoo dhau los. Cov cua daj cua dub tshwm sim los ntawm kev hloov pauv huab cua yuav tsum tau nce ntxiv, yog li lub luag haujlwm ntawm cov roj teeb lub zog cia cov tshuab ua cov khoom siv hluav taws xob thaub qab hauv kev muab lub zog txhim khu kev qha zoo li yuav nce ntxiv.
Qhov tseeb, tib neeg tsis paub tias yuav siv hluav taws xob ntau npaum li cas hauv 20 xyoo tom ntej. Txawm hais tias cov nqi hluav taws xob hauv Asmeskas tau nce 59 feem pua ntawm 20 xyoo dhau los, cov nqi hluav taws xob yav tom ntej tsis tuaj yeem txiav txim siab. Qhov no yog qhov uas photovoltaic systems tuaj rau hauv kev ua si. Los ntawm kev yuav khoom thiab txhim kho PV systems, cov neeg siv hauv tsev tuaj yeem ua kom paub tseeb tus nqi hluav taws xob yav tom ntej, ua kom yooj yim rau kev siv nyiaj thiab npaj rau yav tom ntej.
Raws li kev sib txawv, tus nqi ntawm PV systems tau poob. Xyoo 2010, tus nqi nruab nrab ntawm kev txhim kho PV system nyob hauv tsev yog kwv yees li $ 40, 000, thaum cov nqi tam sim no tau poob ntau dua 70 feem pua los ntawm qhov ntawd, thiab kwv yees li 37 feem pua hauv tsib xyoos dhau los ib leeg. Txawm li cas los xij, PV module nqi tau nce me ntsis hauv 2022 vim yog cov nqi tsheb thauj mus los, cov nqi khoom siv thiab cov nqi tariffs rau cov khoom siv PV txawv teb chaws, thiab cov kev ntxhov siab no tsis xav kom yooj yim rau lub sijhawm luv.
Thaum sib piv cov quotes, tus nqi ib watt ntawm hluav taws xob yog qhov zoo tshaj plaws kev sib piv metric. Lub National Renewable Energy Laboratory tus nqi ntsuas tau hais tias los ntawm 2021, tus nqi hluav taws xob nruab nrab hauv Tebchaws Meskas yuav yog $ 2.65 / W, thaum lub peev xwm nruab nrab nruab nrab ntawm thaj chaw PV systems hauv Tebchaws Meskas yuav yog 7.15kW. Yog li ntawd, tus nqi nruab nrab ntawm kev txhim kho lub tsev PV system yog kwv yees li $ 18,950. Tus nqi nruab nrab ntawm 12.5kWh roj teeb lub zog cia nruab rau nws yog $ 4.26 / W, thiab tus nqi nruab nrab suav nrog cov roj teeb yog $ 30,460.
Cov nqi saum toj no tsis suav nrog kev txhawb nqa. Tam sim no, tsoomfwv Meskas muab 26 feem pua ntawm cov peev nyiaj se credit rau cov tshuab photovoltaic. Cov tshuab photovoltaic tsim nyog tuaj yeem txo cov nqi. Tus nqi ntawm lub tsev photovoltaic system tsis muaj roj teeb lub zog cia yog US $ 14,023. Lub roj teeb lub zog cia qhov system raug teeb tsa. Tus nqi yog $22,540. Piv nrog rau cov nqi hluav taws xob muaj peev xwm ntawm $ 39,460, kev xa khoom ncaj qha ntawm PV systems zoo li qhia meej cov txiaj ntsig kev lag luam.
Ntau tus tswv tsev xav tau qiv nyiaj los yuav tsev PV systems. Nws cov paj laum luv luv yog 2.99 feem pua lossis qis dua, tab sis cov paj laum ntawm 20- xyoo qiv feem ntau yog 5 feem pua rau 8 feem pua lossis siab dua. Raws li qhov nruab nrab cov paj laum ntawm 7 feem pua, ib qho $ 14, 000 qiv nyiaj rau lub tsev PV system yuav tag nrho txog $ 26, 000 tshaj 20 xyoo, thaum lub PV system, nrog rau cov roj teeb cia, yuav tag nrho. txog $42,000.
Raws li ib txwm muaj, thaum cov neeg siv hauv tsev tau txais cov tshuab hluav taws xob photovoltaic, cov tuam txhab hluav taws xob tseem yuav them lawv cov nqi siv hluav taws xob txawm tias 100 feem pua ntawm lawv cov hluav taws xob xav tau. Thaum cov nqi them los ntawm txhua qhov kev siv hluav taws xob sib txawv, lawv feem ntau nyob ib puag ncig $ 10 toj ib hlis. Thiab nyob rau 20 xyoo tom ntej, qhov sib npaug li $ 2,400 uas cov tsev neeg tseem yuav tau them cov nqi hluav taws xob, ntxiv rau cov nqi hluav taws xob ntau dhau.
Raws li cov ntaub ntawv, cov neeg siv hauv tsev tuaj yeem txuag tau ntau npaum li $12,000 nrog rau 20- xyoo qiv. Hauv qee qhov chaw hauv Asmeskas qhov chaw muag khoom hluav taws xob tus nqi siab tshaj qhov nruab nrab, cov neeg siv hauv tsev tuaj yeem txuag tau ntau dua.
