Lub vaj huam sib luag hnub ci uas tseem hu ua photovoltaic vaj huam sib luag yog ib lub cuab yeej uas nqus lub hnub ci thiab hloov lub zog hnub ci mus ua hluav taws xob siv tau. Cov vaj huam sib luag hnub ci muaj ntau lub hlwb hnub ci (cov hlwb photovoltaic). Kev ua haujlwm ntawm lub vaj huam sib luag hnub ci nyob ntawm seb muaj pes tsawg lub hlwb hnub ci.
Ib lub photovoltaic module yog ua los ntawm cov hlwb hnub ci, iav, EVA, daim ntawv rov qab thiab thav duab. Cov tshuab teeb pom kev zoo niaj hnub no siv cov vaj huam sib luag hnub ci monocrystalline lossis cov vaj huam sib luag hnub ci polycrystalline. Cov hlwb hnub ci monocrystalline ua haujlwm tau zoo dua vim lawv tau tsim los ntawm ib lub pob zeb silicon thiab ntau lub pob zeb silicon tau yaj ua ke los tsim cov hlwb polycrystalline. Muaj ntau txoj hauv kev koom nrog hauv kev tsim cov vaj huam sib luag hnub ci.
Tsim cov vaj huam sib luag hnub ci
Muaj 5 yam khoom nyob rau hauv lub vaj huam sib luag hnub ci.
Cov hlwb hnub ci
Muaj ntau yam khoom siv uas siv rau hauv kev tsim cov roj teeb hnub ci. Cov silicon wafers thaum hloov mus ua cov roj teeb hnub ci lawm ces muaj peev xwm hloov lub zog hnub ci mus ua hluav taws xob. Txhua lub roj teeb hnub ci muaj cov silicon wafer uas them zoo (boron) thiab cov silicon wafer uas them tsis zoo (phosphorous). Ib lub vaj huam sib luag hnub ci feem ntau muaj 60 txog 72 lub roj teeb hnub ci.
Iav
Cov iav tempered uas tawv siv los tiv thaiv cov PV cells thiab feem ntau cov iav tuab li 3 txog 4 hli. Lub iav pem hauv ntej tiv thaiv cov cells ntawm qhov kub thiab txias heev thiab tsim los tiv thaiv kev cuam tshuam los ntawm cov khib nyiab hauv huab cua. Cov iav kis tau zoo heev uas paub txog lawv cov hlau tsawg pab txhim kho kev ua haujlwm ntawm cov vaj huam sib luag hnub ci thiab muaj cov txheej tiv thaiv kev cuam tshuam kom txhim kho kev sib kis lub teeb.
Lub thav duab txhuas
Ib lub thav duab txhuas extruded yog siv los tiv thaiv ntug ntawm lub laminate uas yog lub tsev rau cov cell. Qhov no muab ib qho qauv khov kho rau mount lub hnub ci vaj huam sib luag rau hauv qhov chaw. Lub thav duab txhuas yog tsim los kom tsis hnyav thiab muaj peev xwm tiv taus cov khoom siv kho tshuab thiab huab cua tsis zoo. Lub thav duab feem ntau yog nyiaj lossis anodized dub thiab cov ces kaum yog ruaj ntseg los ntawm kev nias lossis nrog cov ntsia hlau lossis clamps.
Cov txheej txheej EVA zaj duab xis
Cov txheej Ethylene-vinyl acetate (EVA) yog siv los qhwv cov roj teeb hnub ci thiab tuav lawv ua ke thaum lub sijhawm tsim khoom. Qhov no yog ib txheej pob tshab uas ruaj khov thiab tiv taus cov av noo thiab kev hloov pauv huab cua hnyav. Cov txheej EVA ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov av noo thiab av qias neeg.
Ob sab ntawm lub hnub ci cell yog laminated nrog EVA zaj duab xis txheej kom muab kev nqus dej thiab tiv thaiv cov xov hlau sib txuas thiab cov cell los ntawm kev cuam tshuam thiab kev co tam sim ntawd.
Lub thawv sib txuas
Lub thawv sib txuas yog siv los txuas cov xov hlau uas txuas cov vaj huam sib luag kom ruaj khov. Qhov no yog lub thawv me me uas tiv taus huab cua uas kuj muaj cov bypass diodes. Lub thawv sib txuas nyob tom qab lub vaj huam sib luag thiab qhov no yog qhov chaw uas txhua lub cell sib txuas thiab yog li ntawd, nws yog ib qho tseem ceeb kom tiv thaiv qhov chaw nruab nrab no ntawm cov dej noo thiab av qias neeg.
Feem ntau cov vaj huam sib luag hnub ci siv tau li ntawm 25 txog 30 xyoo thiab qhov ua haujlwm tau zoo yuav txo qis dua ib lub sijhawm. Txawm li cas los xij, lawv tsis tso tseg ua haujlwm thaum kawg ntawm lub neej hu ua; lawv tsuas yog maj mam lwj thiab lub zog tsim tau raug txo los ntawm qhov uas cov chaw tsim khoom xav tias yog qhov tseem ceeb. Ib qho ntawm cov laj thawj tseem ceeb uas ua rau cov vaj huam sib luag hnub ci muaj lub neej ntev yog vim lawv tsis muaj qhov chaw txav mus los. Tsuav yog lawv tsis raug puas tsuaj los ntawm lwm yam sab nraud, cov vaj huam sib luag hnub ci tuaj yeem ua haujlwm tau ntau xyoo. Qhov feem pua ntawm kev puas tsuaj ntawm vaj huam sib luag hnub ci kuj nyob ntawm hom vaj huam sib luag thiab thaum cov thev naus laus zis vaj huam sib luag hnub ci zoo dua ntau xyoo, qhov feem pua ntawm kev puas tsuaj tau zoo dua.
Raws li kev suav lej, lub neej ntawm lub vaj huam sib luag hnub ci yog qhov ntsuas ntawm feem pua ntawm lub zog tsim tawm ntau xyoo piv rau lub zog ntsuas ntawm lub vaj huam sib luag hnub ci. Cov chaw tsim khoom tsim cov vaj huam sib luag hnub ci xam kwv yees li 0.8% kev poob haujlwm txhua xyoo. Cov vaj huam sib luag hnub ci xav kom tsim tsawg kawg 80% ntawm lub zog ntsuas kom ua haujlwm tau zoo. Piv txwv li, rau lub vaj huam sib luag hnub ci 100 Watt kom ua haujlwm tau zoo, nws yuav tsum tsim tsawg kawg 80 Watt. Txhawm rau paub tias koj lub vaj huam sib luag hnub ci yuav ua haujlwm li cas tom qab ntau xyoo, peb yuav tsum paub qhov nrawm ntawm lub vaj huam sib luag hnub ci. Qhov nruab nrab ntawm qhov nrawm yog 1% txhua xyoo.
Lub sijhawm them rov qab zog (EPBT) yog lub sijhawm rau lub vaj huam sib luag hnub ci los tsim lub zog txaus los them rov qab lub zog siv los tsim lub vaj huam sib luag thiab lub neej ntawm lub vaj huam sib luag hnub ci feem ntau ntev dua li nws EPBT. Lub vaj huam sib luag hnub ci uas tau saib xyuas zoo tuaj yeem ua rau qhov kev puas tsuaj qis dua thiab tseem ua haujlwm tau zoo dua. Kev puas tsuaj ntawm lub vaj huam sib luag hnub ci tuaj yeem tshwm sim los ntawm kev ntxhov siab thermal thiab kev cuam tshuam rau cov khoom ntawm lub vaj huam sib luag hnub ci. Kev kuaj xyuas cov vaj huam sib luag tsis tu ncua tuaj yeem qhia txog teeb meem xws li cov xov hlau raug thiab lwm qhov chaw txhawj xeeb kom ntseeg tau tias cov vaj huam sib luag hnub ci kav ntev dua. Kev tshem tawm cov vaj huam sib luag ntawm cov khib nyiab, hmoov av, dej ntws thiab daus tuaj yeem ua rau cov vaj huam sib luag hnub ci ua haujlwm tau zoo dua. Kev thaiv lub hnub ci thiab khawb lossis lwm yam kev puas tsuaj ntawm lub vaj huam sib luag tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov vaj huam sib luag. Qhov kev puas tsuaj qis heev hauv huab cua nruab nrab.
Kev ua tau zoo ntawm iblub teeb hnub ci txoj kevfeem ntau nyob ntawm qhov ua tau zoo ntawm lub hnub ci vaj huam sib luag uas nws siv. Nrog ntau thiab ntau tus tib neeg thiab cov lag luam nqis peev rau hauv lub zog hnub ci, nws tsuas yog ib txwm xav tias qhov tseem ceeb tshaj plaws thiab kim tshaj plaws ntawm lub teeb pom kev zoo hnub ci yuav ruaj khov thiab tsim nyog cov nyiaj. Cov vaj huam sib luag hnub ci feem ntau siv tam sim no yog monocrystalline thiab polycrystalline hnub ci vaj huam sib luag, ob qho tib si muaj lub neej zoo sib xws. Txawm li cas los xij, qhov kev puas tsuaj ntawm cov vaj huam sib luag hnub ci polycrystalline yog siab dua me ntsis dua li cov vaj huam sib luag hnub ci monocrystalline. Yog tias cov vaj huam sib luag tsis tawg thiab yog tias lawv tsim hluav taws xob txaus rau koj cov kev xav tau, tsis tas yuav hloov cov vaj huam sib luag hnub ci txawm tias tom qab lawv lub sijhawm lav.
Raws li pom hauv daim duab, Zenith Teeb pom kev zoo yog lub chaw tsim khoom tshaj lij ntawm txhua yam teeb pom kev zoo hnub ci thiab lwm yam khoom muaj feem xyuam, yog tias koj muaj lus nug lossis project, thov tsis txhob yig tiv tauj peb. tiv tauj peb.
