Piv txwv li, ntawm no yog cov lus nug tseem ceeb uas koj yuav xav tau teb ua ntej hnub ci teeb tsa: "Lub hnub ci vaj huam sib luag tsim hluav taws xob ntau npaum li cas?"Cia peb khawb rau hauv cov lus teb.
Hnub ci vaj huam sib luag ua haujlwm li cas?
Kev teeb tsa lub hnub ci vaj huam sib luag nyob hauv tsev tau nce los ntawm 2.9 gigawatts hauv xyoo 2020 txog 3.9 gigawatts hauv 2021, raws li US Energy Information Administration (EIA), tsoomfwv lub koomhaum.
Koj puas paub tias hnub ci vaj huam sib luag ua haujlwm li cas?Muab yooj yim heev, hnub ci zog yog tsim thaum lub hnub ci rau ntawm photovoltaic panels uas ua rau koj lub hnub ci vaj huam sib luag.Cov hlwb no hloov lub hnub lub zog rau hauv hluav taws xob thaum lub hnub ci yog nqus los ntawm PV hlwb.Qhov no tsim cov nqi hluav taws xob thiab ua rau hluav taws xob ntws.Tus nqi hluav taws xob tsim tawm nyob ntawm ob peb yam, uas peb yuav nkag mus rau hauv ntu tom ntej.
Lub hnub ci vaj huam sib luag muab lub zog txuas ntxiv dua tshiab, txo cov nqi hluav taws xob, kev pov hwm tiv thaiv kev nce nqi hluav taws xob, cov txiaj ntsig ib puag ncig thiab kev ywj pheej ntawm lub zog.
Lub Zog Muaj Zog Ua Ib TugHnub Ci Vaj Huam Sib LuagTsim tawm?
Lub hnub ci vaj huam sib luag tuaj yeem tsim hluav taws xob ntau npaum li cas?Tus nqi ntawm lub zog tsim los ntawm lub hnub ci vaj huam sib luag ib hnub, tseem hu ua "wattage" thiab ntsuas los ntawm kilowatt-teev, nyob ntawm ntau yam, xws li lub hnub ci siab tshaj teev thiab vaj huam sib luag efficiency.Feem ntau cov hnub ci vaj huam sib luag rau cov tsev tsim tawm ib ncig ntawm 250 - 400 watts tab sis rau cov tsev loj, tuaj yeem tsim tau txog 750 - 850 ib kilowatt teev ib xyoos ib zaug.
Hnub ci vaj huam sib luag manufacturers txiav txim siab lub hnub ci fais fab tso zis rau cov khoom raws li xoom obstructions.Tab sis qhov tseeb, tus nqi ntawm lub hnub ci zog ntawm lub vaj huam sib luag tsim tau txawv nyob ntawm seb lub hwj chim tso tawm ntawm lub vaj huam sib luag thiab pes tsawg lub hnub ci lub sij hawm uas lub hnub ci zog ntawm lub tsev nyob.Siv cov ntaub ntawv los ntawm cov chaw tsim khoom ua qhov chaw pib raws li kev suav rau koj lub tsev.
Yuav xam pes tsawg Watts AHnub Ci Vaj Huam Sib LuagTsim tawm
Lub hnub ci vaj huam sib luag tsim muaj pes tsawg watts?"Watts" xa mus rau lub vaj huam sib luag qhov xav tau lub zog tsim khoom raws li lub hnub ci zoo meej, qhov kub thiab txias thiab lwm yam.Koj tuaj yeem xam ntau npaum li cas lub hnub ci vaj huam sib luag tsim los ntawm kev sib npaug ntawm lub hnub ci vaj huam sib luag hluav taws xob tso tawm los ntawm koj lub hnub ci siab tshaj plaws hauv ib hnub:
Kilowatt-teev (kWh) = (teev hnub ci x Watts) / 1,000
Hauv lwm lo lus, cia peb hais tias koj tau txais 6 teev ncaj qha tshav ntuj txhua hnub.Muab qhov ntawd los ntawm wattage ntawm cov chaw tsim khoom vaj huam sib luag, xws li 300 watts.
Kilowatt-teev (kWh) = (6 teev x 300 watts) / 1,000
Hauv qhov no, tus naj npawb ntawm kilowatt-teev tsim tawm yuav yog 1.8 kWh.Tom ntej no, xam cov hauv qab no rau tus naj npawb ntawm kWh ib xyoos twg siv cov qauv hauv qab no:
(1.8 kWh/hnub) x (365 hnub/xyoo) = 657 kWh/xyoo
Nyob rau hauv rooj plaub no, lub hnub ci vaj huam sib luag tso tawm ntawm lub vaj huam sib luag tshwj xeeb no yuav tsim 657 kWh ib xyoos twg hauv cov khoom siv hluav taws xob.
Dab tsi cuam tshuam ntau npaum li cas Lub Hnub Ci Vaj Huam Sib Luag Tsim?
Raws li peb tau hais lawm, ntau yam cuam tshuam rau lub hnub ci vaj huam sib luag tsim hluav taws xob, suav nrog lub hnub ci vaj huam sib luag loj, lub hnub ci siab tshaj plaws, hnub ci vaj huam sib luag efficiency thiab lub cev muaj zog:
- Hnub ci vaj huam sib luag loj: Lub hnub ci vaj huam sib luag loj tuaj yeem cuam tshuam rau lub hnub ci zog uas tsim los ntawm lub hnub ci vaj huam sib luag.Tus naj npawb ntawm lub hnub ci hauv ib lub vaj huam sib luag tuaj yeem cuam tshuam rau lub zog nws tsim.Hnub ci vaj huam sib luag feem ntau muaj 60 lossis 72 lub hlwb - feem ntau, 72 lub hlwb tsim hluav taws xob ntau dua.
- Peak hnub ci cov sij hawm: Peak hnub ci lub sij hawm tseem ceeb nyob rau hauv lub hnub ci zog tsim vim hais tias lawv pab koj txiav txim seb muaj pes tsawg teev ntawm lub hnub ci hnyav koj tau txais thiab yuav pab tau koj txiav txim seb tus nqi ntawm hluav taws xob koj lub hnub ci panels tsim tau.
- Hnub ci vaj huam sib luag efficiency: Hnub ci vaj huam sib luag efficiency ncaj qha cuam tshuam rau lub hnub ci zog vim nws ntsuas cov nqi hluav taws xob hauv ib cheeb tsam.Piv txwv li, "monocrystalline" thiab "polycrystalline" yog ob yam sib txawv ntawm lub hnub ci vaj huam sib luag - monocrystalline hnub ci hlwb siv ib leeg-crystal silicone, uas yog nyias, siv tau zoo.Lawv muab kev ua haujlwm ntau dua vim tias cov hluav taws xob uas tsim hluav taws xob tuaj yeem txav mus los.Polycrystalline solar cells feem ntau muaj kev ua haujlwm qis dua li cov hnub ci monocrystalline thiab tsis tshua kim.Cov neeg tsim khoom yaj silicon crystals ua ke, uas txhais tau hais tias electrons txav tsawg dua ywj pheej.Monocrystalline hlwb muaj qhov ua tau zoo ntawm 15% - 20% thiab polycrystalline hlwb muaj qhov ua tau zoo ntawm 13% - 16%.
- Tsis muaj kev cuam tshuam ntawm lub cev: Koj tuaj yeem tsim hluav taws xob ntau npaum li cas yog tias koj muaj ntoo ntau dhau ntawm koj lub tsev lossis lwm yam kev cuam tshuam?Lawm, lo lus teb rau "lub zog npaum li cas ntawm lub hnub ci vaj huam sib luag tsim tau?"yuav nyob ntawm seb lub hnub ci npaum li cas tuaj yeem nkag mus rau koj lub hnub ci vaj huam sib luag.
