Tsis muaj hluav taws xob
Lub zog hluav taws xob photovoltaic hloov lub teeb lub zog ncaj qha mus rau DC lub zog los ntawm cov yam ntxwv ntawm cov khoom siv hluav taws xob, thiab tom qab ntawd hloov DC lub zog rau hauv AC lub zog uas tuaj yeem siv los ntawm peb los ntawm inverter.
Lub tshuab hluav taws xob photovoltaic yog tsim los ntawm cov khoom siv hluav taws xob photovoltaic, brackets, DC cables, inverters, AC cables, lub hwj chim faib khoom, transformers, thiab lwm yam. Photovoltaic modules thiab DC cables muaj DC tam sim no sab hauv, thiab tsis muaj kev hloov pauv. Lawv tsuas tuaj yeem tsim hluav taws xob, tsis yog magnetic teb.
Txawm hais tias cov zis transformer yog alternating tam sim no, qhov zaus yog tsawg heev, tsuas yog 50 Hz, thiab cov magnetic teb generated yog tsawg heev. Inverter yog ib qho khoom siv uas hloov tam sim no ncaj qha mus rau qhov hloov tam sim no. Muaj lub zog hluav taws xob hloov hluav taws xob sab hauv, thiab qhov zaus feem ntau yog 5-20KHz, yog li nws yuav tsim hluav taws xob hloov pauv, yog li nws tseem yuav tsim hluav taws xob hluav taws xob. Lub teb chaws muaj cov qauv nruj rau electromagnetic compatibility ntawm photovoltaic inverters.
Piv nrog rau cov khoom siv hauv tsev, cov hluav taws xob hluav taws xob hluav taws xob ntawm photovoltaic inverters yog hais txog tib yam li cov khoos phis tawj phau ntawv, thiab qis dua induction cookers, hair dryers, thiab tub yees.
Yog li ntawd, kev tsim kho ntawm photovoltaic fais fab nroj tsuag yuav tsis tsuas yog ua rau muaj kev puas tsuaj rau tib neeg noj qab haus huv, tab sis kuj muab lub ntiaj teb ntsuab thiab huv si zoo zog, uas yog lub neej yav tom ntej lub zog txoj kev loj hlob ntawm noob neej.
Cov txheej txheem tsim khoom tsis yog" siab zog noj"
Kuv tsis paub tias muaj pes tsawg tus neeg hais lus phem hais tias photovoltaic fais fab tuag yog qhov muaj kuab paug siab thiab siv zog ntau hauv cov txheej txheem tsim khoom. Cov lus xaiv zoo li no tau nthuav tawm ntau dua ib zaug.
Kev lag luam photovoltaic feem ntau suav nrog plaub qhov txuas: crystalline silicon purification, silicon ingots thiab wafers, photovoltaic cells thiab photovoltaic modules. Ntawm lawv, kev ua kom huv ntawm crystalline silicon yuav tsum ua kom tiav nyob rau hauv qhov kub thiab txias thiab siv hluav taws xob ntau, suav txog li 56% -72% ntawm tag nrho cov kev siv zog. Nws yog cov txheej txheem tsim tshuaj tseem ceeb tshaj plaws hauv kev lag luam saw; thiab cov" muaj kuab paug siab" los ntawm high-purity polysilicon By-products ua nyob rau hauv ntau lawm.
Crystalline silicon purification yog qhov tseeb ntawm kev lag luam loj, kev siv hluav taws xob ntau. Txawm li cas los xij, qhov no tsis tau txhais hais tias cov khoom siv hluav taws xob photovoltaic muaj kev siv zog siab. Nws yog ib qho tsim nyog los hloov tag nrho lub zog siv hauv kev tsim ib chav tsev ntawm photovoltaic modules rau hauv kev siv hluav taws xob thiab muab piv nrog lub zog tsim hluav taws xob ntawm cov modules thaum lawv lub neej. Hauv xyoo 2015, Ministry of Industry thiab Information Technology tau tshaj tawm" Specification Conditions rau Photovoltaic Manufacturing Industry", qhia tias kev siv hluav taws xob ntawm cov txheej txheem ntau lawm polysilicon yuav tsum tsawg dua 120 kWh / kg; Kev tsim kho tshiab thiab nthuav dav yuav tsum tsawg dua 100 kWh / kg, thiab qib kev siv hluav taws xob no yuav tsum nyob ze rau qib tam sim no Lub ntiaj teb' qib siab heev.
Raws li qhov kev hloov pauv no, kev siv hluav taws xob photovoltaic uas ua tau raws li cov cai hauv lub tebchaws yuav tsum muaj 0.6-1.2 kilowatt-teev hluav taws xob los tsim ib lub watt ntawm photovoltaic modules. Raws li 25-xyoo lub neej ncua ntawm photovoltaic modules, photovoltaic fais fab tuag ntau dua li kev siv hluav taws xob ntau.
Tsis muaj teeb meem lub teeb
Lub teeb muaj kuab paug yog hem tib neeg' kev noj qab haus huv. Nyob rau hauv lub neej txhua hnub, tib neeg' qhov teeb meem tshwm sim feem ntau yog kiv taub hau ntawm cov neeg taug kev thiab cov neeg tsav tsheb los ntawm qhov kev xav ntawm cov iav iav, thiab qhov tsis xis nyob los ntawm qhov teeb pom kev tsis tsim nyog thaum hmo ntuj rau tib neeg lub cev.
Yog li txhua tus neeg txhawj xeeb heev txog seb puas muaj lub teeb paug hauv kev teeb tsa ntawm photovoltaic modules. Qhov tseeb, qhov pom lub teeb pom kev coefficient ntawm cov iav tempered zoo tib yam yog 9% ~ 11%, uas yuav tsis ua rau lub teeb paug. Lub photovoltaic module siv tib hom iav raws li lub tsev, thiab nws yuav tsis ua rau lub teeb muaj kuab paug.
Lub hauv paus ntawm lub teeb muaj kuab paug yog pom lub teeb. Lub tshuab hluav taws xob tsim hluav taws xob hauv lub tshuab hluav taws xob photovoltaic yuav nqus cov teeb pom kev zoo thiab hloov mus rau hauv hluav taws xob hluav taws xob, uas yuav txo qhov kev xav ntawm lub teeb pom kev ntxiv.
Thiab nrog cov thev naus laus zis tshiab, ntau cov khoom siv hauv tsev photovoltaic tuaj yeem ua rau hauv qhov chaw frosted, uas tuaj yeem txo qhov kev xav ntawm lub teeb pom kev.
Tsis muaj suab nrov, tsis muaj emissions
Ob lub ntsiab lus no kuj yooj yim to taub. Kev tsim hluav taws xob photovoltaic yog kev hloov pauv ntawm lub hnub ci zog rau hauv hluav taws xob hluav taws xob. Nws yog photoelectric hloov dua siab tshiab. Yuav tsis muaj suab nrov lossis muaj kuab paug emissions thaum lub sijhawm ua haujlwm. Nws yog qhov tsim nyog rau kev teeb tsa ntawm thaj chaw nyob thiab kev lag luam thiab kev lag luam rooftops.
Nyob rau hauv xyoo tas los no, cov khoom siv hluav taws xob photovoltaic tau tsim sai heev, thiab feem ntau yog cov khoom siv hluav taws xob zoo nkauj photovoltaic tsim nyog rau kev teeb tsa ntawm lub ru tsev, muaj kev ua haujlwm ntawm kev txuag hluav taws xob thiab txo qis emissions, thiab tseem tuaj yeem tiv thaiv thiab tsis muaj dej.
Ntau lub chaw tsim khoom thiab cov neeg nyob hauv tau teeb tsa cov chaw siv hluav taws xob photovoltaic ntawm lub ru tsev. Peb tuaj yeem paub qhov tsis muaj suab nrov thiab emission-dawb lub zog tsim cov txheej txheem.
