Nyob rau hauv xyoo tas los no, qhov no yog ib lo lus nug uas tau tsa los ntawm ntau thiab ntau tus neeg.Raws li International Energy Agency, ntiaj teb no hnub ci zog tsim nyob rau hauv 2020 yog 156 terawatt-teev.Raws li tsoom fwv UK, lub UK tsim ntau tshaj 13,400 megawatts. ntawm lub zog thiab muaj ntau tshaj li ib lab ntsia. Hnub ci vaj huam sib luag kev teeb tsa kuj tau nce los ntawm qhov zoo siab 1.6% los ntawm 2020 txog 2021.Raws li ResearchandMarkets.com, lub hnub ci kev lag luam yuav tsum loj hlob los ntawm 20.5% mus rau $ 222.3 billion (£ 164 billion) los ntawm 2019 txog 2026.
Raws li "Tus Saib Xyuas" tsab ntawv ceeb toom, UK tam sim no tab tom ntsib teeb meem ntawm cov nqi hluav taws xob, thiab cov nqi hluav taws xob tuaj yeem nce li 50%. UK lub zog tswj hluav taws xob Ofgem tau tshaj tawm qhov nce ntawm tus nqi hluav taws xob (qhov siab tshaj plaws tus neeg muab khoom siv hluav taws xob. tuaj yeem them) los ntawm 1 Lub Plaub Hlis 2022.Qhov ntawd txhais tau hais tias ntau tus neeg xav kom tau txais txiaj ntsig ntau ntawm lawv cov nyiaj thaum nws los txog rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob xws li hnub ci.Tab sis cov hnub ci vaj huam sib luag puas tsim nyog?
Hnub ci vaj huam sib luag, hu ua photovoltaics (PV), muaj ntau lub hlwb semiconductor, feem ntau yog ua los ntawm silicon.Lub silicon yog nyob rau hauv ib lub xeev crystalline thiab yog sandwiched ntawm ob txheej conductive, txheej saum toj kawg nkaus yog noob nrog phosphorus thiab hauv qab yog boron.Thaum tshav ntuj dhau los ntawm cov txheej txheem no, nws ua rau cov khoom siv hluav taws xob dhau los ntawm cov khaubncaws sab nraud povtseg thiab tsim kom muaj hluav taws xob.Raws li Lub Zog Txuag Trust, cov nqi no tuaj yeem sau thiab khaws cia rau cov khoom siv hluav taws xob hauv tsev.
Tus nqi ntawm lub zog los ntawm lub hnub ci PV khoom tuaj yeem sib txawv nyob ntawm nws qhov loj thiab qhov chaw, tab sis feem ntau txhua lub vaj huam sib luag tsim tawm 200-350 watts ib hnub, thiab txhua qhov PV system muaj 10 mus rau 15 panels.Qhov nruab nrab UK tsev neeg tam sim no siv ntawm 8 thiab 10 kilowatts ib hnub twg, raws li lub zog sib piv lub vev xaib UKPower.co.uk.
Lub ntsiab nyiaj txiag sib txawv ntawm cov pa hluav taws xob thiab lub hnub ci zog yog tus nqi pem hauv ntej ntawm kev txhim kho lub hnub ci photovoltaic system.“Peb muab kev teeb tsa tus nqi £ 4,800 [kwv yees $ 6,500] rau 3.5 kW kev teeb tsa hauv tsev, suav nrog kev ua haujlwm tab sis tsis suav nrog roj teeb.Qhov no yog qhov nruab nrab qhov loj ntawm UK cov kab ke hauv tsev thiab yuav tsum nyob ib puag ncig 15 txog 20 square metres [kwv yees] 162 txog 215 square feet] panels, "Brian Horn, tus kws tshaj lij kev pom zoo thiab tus kws pab tswv yim ntawm Energy Efficiency Trust, hais rau LiveScience hauv email.
Txawm hais tias tus nqi pib siab, qhov nruab nrab ntawm lub neej ua haujlwm ntawm lub hnub ci PV yog nyob ib ncig ntawm 30-35 xyoo, txawm hais tias qee cov tuam txhab tau thov ntev dua, raws li Lub Chaw Haujlwm Saib Xyuas Hluav Taws Xob thiab Hluav Taws Xob Hluav Taws Xob.
hnub ci vaj huam sib luag roj teeb bank
Kuj tseem muaj kev xaiv los nqis peev hauv cov roj teeb kom sau tau ntau lub zog uas tsim los ntawm lub hnub ci photovoltaic system.Los yog koj tuaj yeem muag nws.
Yog tias lub tshuab hluav taws xob photovoltaic tsim hluav taws xob ntau dua li koj lub tsev siv, nws muaj peev xwm muag cov khoom siv hluav taws xob ntau dhau rau cov khoom siv hluav taws xob raws li Smart Export Guarantee (SEG).SEG tsuas yog muaj nyob hauv Askiv, Scotland thiab Wales.
Raws li cov tswv yim, cov tuam txhab hluav taws xob sib txawv tau teeb tsa tus nqi ntawm tus nqi uas lawv txaus siab yuav lub zog ntau dhau los ntawm koj lub hnub ci PV system nrog rau lwm cov khoom siv hluav taws xob txuas ntxiv xws li hydro lossis cua turbines.Piv txwv li, txij Lub Ob Hlis 2022, lub chaw muab hluav taws xob E. ON yog tam sim no muab cov nqi nce mus txog 5.5 pence (kwv yees li 7 xees) ib kilowatt.Tsis muaj cov nqi them nyiaj tas li raws li SEG, cov neeg muag khoom tuaj yeem muab cov nqi ruaj khov lossis hloov pauv tau, txawm li cas los xij, raws li Energy Efficiency Trust, tus nqi yuav tsum ib txwm muaj. saum toj no zero.
"Rau cov tsev nrog lub hnub ci vaj huam sib luag thiab cov kws tshaj lij kev lees paub, hauv London thiab Sab Qab Teb Sab Hnub Tuaj ntawm Askiv, qhov chaw uas cov neeg nyob hauv lawv lub sijhawm feem ntau nyob hauv tsev, txuag £ 385 [kwv yees $ 520] ib xyoos, nrog rau kev them rov qab ntawm thaj tsam 16 xyoo [cov duab kho Nov 2021] hli]”, Horn hais.
Raws li Horn, lub hnub ci vaj huam sib luag tsis tsuas yog txuag hluav taws xob thiab tseem ua tau nyiaj hauv cov txheej txheem, lawv kuj ntxiv tus nqi rau koj lub tsev. "Muaj pov thawj tseeb tias cov tsev uas muaj kev ua tau zoo zog tau muag rau tus nqi siab dua, thiab cov hnub ci vaj huam sib luag yog qhov tseem ceeb hauv qhov kev ua tau zoo.Nrog rau cov nqi tsis ntev los no tau nce thoob plaws hauv kev ua lag luam, qhov cuam tshuam ntawm cov hnub ci vaj huam sib luag ntawm cov nqi tsev Nws zoo nkaus li muaj kev tsom mus rau kev txo cov kev xav tau ntawm lub zog thiab hloov mus rau cov khoom siv hluav taws xob tauj dua tshiab, "Horn tau hais tias. Lub hnub ci fais fab tuaj yeem nce tus nqi muag ntawm ib lub tsev los ntawm £ 1,800 (kwv yees $ 2,400).
Tau kawg, hnub ci tsis yog tsuas yog zoo rau peb cov nyiaj hauv tuam txhab nyiaj xwb, tab sis nws kuj pab txo qhov kev puas tsuaj ntawm kev lag luam hluav taws xob ntawm peb ib puag ncig.Cov kev lag luam uas tawm hauv tsev cog khoom feem ntau yog hluav taws xob thiab hluav taws xob tsim hluav taws xob.Qhov kev lag luam muaj 25 feem pua. ntawm tag nrho cov emissions thoob ntiaj teb, raws li US Environmental Protection Agency.
Raws li lub zog ruaj khov thiab txuas ntxiv mus, lub hnub ci photovoltaic systems yog cov pa roj carbon nruab nrab thiab emit tsis muaj lub tsev cog khoom gases.Raws li Energy Efficiency Trust, qhov nruab nrab UK cov tsev siv PV system yuav txuag tau 1.3 txog 1.6 metric tonnes (1.43 txog 1.76 tonnes) carbon. emissions ib xyoos twg.
"Koj tuaj yeem sib txuas hnub ci PV nrog lwm cov thev naus laus zis tshiab xws li cov twj tso cua sov.Cov thev naus laus zis no ua haujlwm zoo nrog rau ib leeg vim tias lub hnub ci PV tso tawm qee zaum ncaj qha rau lub tshuab hluav taws xob, pab txo cov nqi cua sov, "Peb pom zoo kom sab laj koj tus neeg tsim khoom kom paub meej cov kev tu ncua ua ntej koj cog lus rau kev txhim kho lub hnub ci PV system," nws ntxiv.
Hnub ci PV vaj huam sib luag tsis yog qhov tsis muaj kev txwv thiab hmoov tsis yog tsis yog txhua lub tsev sib haum nrog lub hnub ci PV kev teeb tsa. "Raws li qhov loj thiab qhov chaw tsim nyog ru tsev muaj rau kev txhim kho PV panels, tej zaum yuav muaj qee qhov kev txwv," Horn hais.
Lwm qhov kev txiav txim siab yog seb koj puas xav tau kev tso cai rau kev teeb tsa lub hnub ci PV system. Cov vaj tse tiv thaiv, cov tsev nyob hauv pem teb thiab cov chaw nyob hauv cov chaw tiv thaiv yuav tsum tau tso cai ua ntej kev teeb tsa.
Huab cua tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub hnub ci PV los tsim hluav taws xob.Raws li E.ON, txawm hais tias lub hnub ci vaj huam sib luag yuav raug tshav ntuj txaus los tsim hluav taws xob, suav nrog hnub huab cua thiab lub caij ntuj no, nws yuav tsis yog qhov ua tau zoo tshaj plaws.
"Txawm hais tias koj lub kaw lus loj npaum li cas, koj tsis tuaj yeem tsim txhua lub zog uas koj xav tau thiab xav tau los ntawm kab sib chaws los txhawb nws.Txawm li cas los xij, koj tuaj yeem kho koj lub zog siv hluav taws xob, xws li siv cov khoom siv los tsim hluav taws xob thaum nruab hnub thaum cov vaj huam sib luag tawm, "Horn tau hais.
Ntxiv rau kev txhim kho lub hnub ci PV system, muaj lwm cov nqi los txiav txim siab, xws li kev saib xyuas.Cov hluav taws xob uas tsim los ntawm lub hnub ci vaj huam sib luag yog hu ua direct tam sim no (DC), tab sis cov khoom siv hauv tsev siv alternating tam sim no (AC), yog li inverters raug teeb tsa los hloov. direct tam sim no.Raws li lub zog sib piv lub vev xaib GreenMatch.co.uk, cov inverters no muaj kev ua neej nyob nruab nrab ntawm tsib thiab 10 xyoo.Tus nqi ntawm kev hloov pauv yuav txawv los ntawm tus neeg muag khoom, txawm li cas los xij, raws li tus qauv lub cev MCS (Micro-Generation Certification Scheme ), qhov no raug nqi £ 800 (~ $ 1,088).
Tau txais qhov zoo tshaj plaws ntawm lub hnub ci PV system rau koj lub tsev txhais tau tias yuav khoom nyob ib puag ncig. "Peb pom zoo kom xaiv cov ntawv pov thawj thiab cov ntawv pov thawj uas tau lees paub thaum txhim kho txhua hom kev siv hluav taws xob hauv tsev.Cov nqi yuav txawv ntawm cov neeg tsim khoom thiab cov khoom lag luam, yog li peb pom zoo kom pib ua haujlwm yam tsawg kawg tau txais nqe lus los ntawm peb tus neeg tsim khoom, "Horn hais. hais.
Tsis muaj qhov tsis ntseeg tias qhov zoo ib puag ncig ntawm cov hnub ci vaj huam sib luag yog qhov tsim nyog.Raws li lawv cov nyiaj txiag muaj txiaj ntsig, hnub ci PV tshuab muaj peev xwm txuag tau nyiaj ntau, tab sis tus nqi pib yog siab.Txhua lub tsev sib txawv ntawm kev siv hluav taws xob. thiab lub peev xwm ntawm lub hnub ci vaj huam sib luag, uas yuav cuam tshuam txog nyiaj npaum li cas koj tuaj yeem txuag tau nrog lub hnub ci PV system.Los pab koj txiav txim siab zaum kawg, Lub Zog Txuag Trust muab lub tshuab xam zauv los ntsuas seb koj tuaj yeem txuag tau li cas nrog lub hnub ci zog.
