Qhov sib txawv ntawm monocrystalline thiab polycrystalline solar panels
1. Los ntawm qhov pom ntawm tus qauv, plaub fab ntawm monocrystalline silicon cell yog arc-puab thiab tsis muaj tus qauv ntawm saum npoo.
Plaub fab ntawm cov polycrystalline silicon cell yog cov ces kaum, thiab saum npoo muaj cov qauv zoo ib yam li paj dej khov.
2.2. Rau cov neeg siv, tsis muaj qhov sib txawv ntau ntawm monocrystalline silicon cells thiab polycrystalline silicon cells hauv kev siv cov khoom siv, thiab lawv lub neej thiab kev ruaj ntseg zoo heev. Qhov kev hloov pauv nruab nrab ntawm cov cell monocrystalline silicon siab dua li ntawm polycrystalline silicon, tab sis tus nqi tam sim no kuj siab dua li ntawm polycrystalline silicon. 3 3. Hauv cov txheej txheem tsim qauv, cov cell polycrystalline muaj cov txheej txheem tsim khoom tsawg dua li cov cell monocrystalline. Yog li ntawd, lub zog siv hauv kev tsim cov txheej txheem ntawm polycrystalline silicon solar cells yog me ntsis tsawg dua li ntawm monocrystalline silicon solar cells, tab sis lub zog tsim ntawm monocrystalline solar cells yog siab dua. Xam qhov kev siv zog sib piv tsis txawv ntau.
Kev sib piv ntawm monocrystalline photovoltaic modules thiab polycrystalline photovoltaic modules
1) Saib keeb kwm, daim ntawv thov ib leeg-siv lead ua photovoltaic vaj huam sib luag tau ntxov dua li ntawm polycrystalline photovoltaic panels.
2) Hais txog kev siv, daim ntawv thov polycrystalline silicon hauv cov chaw siv hluav taws xob ntau dua li cov monocrystalline silicon, nrog monocrystalline silicon suav rau 30% thiab polycrystalline silicon suav txog 70%.
3) Saib ntawm qhov tsos, monocrystalline silicon yog xim xiav tsaus, yuav luag dub, polycrystalline silicon yog ntuj xiav, thiab xim yog ci, ib lub xov tooj ntawm tes siv ib puag ncig ntawm plaub fab, thiab polycrystalline cell yog xwmfab.
4) Saib ntawm qhov hloov pauv, qhov ua tau zoo ntawm ib qho siv lead ua siab dua li ntawm polycrystal, li 10%-20%.
5) Saib ntawm tus nqi, tus nqi ntawm ib qho siv lead ua yog me ntsis kim dua li ntawm polycrystalline. Tus nqi ntawm cov tuam txhab sib txawv sib txawv, thiab tus nqi lag luam yog tsib xees rau ib dime ib watt.
6) Saib ntawm cov ntaub ntawv ntsuas ntawm kev txo qis, nws tau pom tias ib leeg siv lead ua thiab polycrystalline muaj lawv tus kheej qhov zoo, thiab nws tsis tuaj yeem paub qhov txawv ntawm qhov ua kom nrawm los ntawm ib qho siv lead ua thiab polycrystalline pom. Hais lus zoo, cov khoom lag luam zoo (qib kev sib khi, seb puas muaj phau ntawv xov xwm, txawm tias nws tawg), muaj kev cuam tshuam ntau dua rau kev txo qis.
7) Saib tus nqi/kev ua piv txwv, tam sim no, tus nqi/kev ua haujlwm piv ntawm polycrystalline yog siab dua me ntsis ntawm ib leeg siv lead ua. Nws tsuas yog rau tam sim no. Raws li tus nqi ntawm cov khoom siv ib leeg zuj zus, qhov rov qab tuaj yeem tshwm sim hauv ob peb xyoos tom ntej no.
