Tsim cov Pawg ntawm Hnub Ci Backsheet

Kev lag luam hnub ci tau ua kom muaj kev vam meej nyob rau ob peb lub xyoo dhau los, nrog lub hnub ci vaj huam sib luag tau dhau los ua lub hauv paus ntawm kev daws teeb meem hluav taws xob tauj dua tshiab. Qhov tseem ceeb ntawm cov vaj huam sib luag no yog lub hnub ci backsheet, uas ua lub luag haujlwm tseem ceeb hauv kev ua kom lub neej ntev thiab kev ua haujlwm ntawm lub hnub ci modules. Kev nkag siab txog hnub ci backsheet pawg tsim yog qhov tseem ceeb rau cov tuam txhab, cov neeg tsim khoom thiab cov neeg siv khoom vim nws cuam tshuam rau kev ua tau zoo, ua haujlwm ntev thiab tag nrho cov kev ntseeg tau.

Lub hnub ci vaj huam sib luag yog dab tsi?

A hnub ci backsheetyog ib txheej tiv thaiv nyob rau sab nraum qab ntawm lub hnub ci vaj huam sib luag. Nws muaj ntau yam haujlwm xws li hluav taws xob rwb thaiv tsev, ya raws thiab UV tsis kam. Backsheets yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees ntawm lub hnub ci hlwb thiab ua kom cov vaj huam sib luag ua haujlwm tau zoo thoob plaws hauv lawv lub neej. Muab nws qhov tseem ceeb, xaiv cov ntaub ntawv rov qab zoo tuaj yeem cuam tshuam qhov kev ua tau zoo thiab kav ntev ntawm koj lub hnub ci vaj huam sib luag.

Classification ntawm solar back panels

Cov qeb tsim ntawm hnub ci backsheets tuaj yeem txheeb cais raws li cov khoom siv, kev ua haujlwm thiab daim ntawv thov. Ntawm no yog cov pawg tseem ceeb:

1. Khoom siv

Hnub ci backsheets yog tsim los ntawm peb cov ntaub ntawv:

• Polyvinyl fluoride (PVF):PVF backsheets paub txog lawv cov huab cua zoo heev thiab ua haujlwm ntev thiab feem ntau siv hauv cov hnub ci ua haujlwm siab. Lawv muab kev tiv thaiv UV zoo heev thiab tiv taus tshuaj lom neeg degradation, ua rau lawv zoo tagnrho rau qhov hnyav ib puag ncig.
• Polyester (PET):Polyester backsheets yog lub teeb yuag thiab tus nqi tsim nyog, ua rau lawv muaj kev xaiv nrov rau ntau lub tuam txhab. Thaum lawv muaj kev tiv thaiv zoo tiv thaiv ya raws thiab UV rays, lawv yuav tsis zoo li PVF xaiv. Txawm li cas los xij, kev nce qib hauv polyester thev naus laus zis tau ua rau muaj kev ua tau zoo dua qub.
• Polyethylene (PE):PE backsheet yog qhov kev xaiv pheej yig tshaj plaws thiab feem ntau siv hauv cov hnub ci qis kawg. Thaum lawv muab kev tiv thaiv yooj yim, lawv yuav tsis muab tib theem ntawm kev ua haujlwm ntev thiab ua haujlwm zoo li PVF lossis PET cov ntaub ntawv.

2. Muaj nuj nqi

Cov haujlwm ntawm hnub ci rov qab vaj huam sib luag tuaj yeem faib lawv:

• Insulating cov ntaub ntawv:Cov ntaub ntawv rov qab no feem ntau yog siv rau cov hluav taws xob rwb thaiv tsev, tiv thaiv kev xau hluav taws xob uas tuaj yeem cuam tshuam kev nyab xeeb thiab kev ua haujlwm ntawm koj lub hnub ci vaj huam sib luag.
• Moisture-Resistant Backsheets:Cov ntawv rov qab no tsom rau kev tiv thaiv kev nkag mus ntawm cov dej noo, uas tuaj yeem ua rau corrosion thiab degradation ntawm lub hnub ci hlwb. Lawv yog cov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov huab cua ntub.
• UV resistant backsheet:UV tsis kam yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees ntawm koj lub hnub ci vaj huam sib luag rau lub sijhawm ntev. Ib daim ntawv rov qab uas muab kev tiv thaiv UV siab pab tiv thaiv yellowing thiab degradation, kom ntseeg tau tias kev ua haujlwm ntev.

3. Cov qeb raws li kev thov

Hnub ci backsheets kuj tseem tuaj yeem raug cais raws li lawv daim ntawv thov:

• Solar vaj huam sib luag:Backsheets siv nyob rau hauv daim ntawv thov nyob rau hauv lub tsev feem ntau saib xyuas qhov zoo nkauj thiab tus nqi-zoo thaum tseem muab kev tiv thaiv txaus.
• Commercial solar panels:Cov vaj huam sib luag rov qab no feem ntau yog tsim los rau kev ua haujlwm siab dua thiab ua haujlwm ntev txij li kev teeb tsa kev lag luam feem ntau ntsib qhov xav tau ntau dua.
• Utility scale solar panels:Cov phiaj xwm siv hluav taws xob xav tau cov ntaub ntawv rov qab uas tuaj yeem tiv taus huab cua huab cua thiab muab kev ntseeg tau ntev, ua cov ntaub ntawv ua tau zoo xws li PVF yog qhov kev xaiv zoo tshaj plaws.

nyob rau hauv xaus

Kev tsim ntawmhnub ci backsheetpawg yog ib qho tseem ceeb ntawm lub hnub ci vaj huam sib luag tsim thiab tsim khoom. Los ntawm kev nkag siab txog ntau yam ntawm cov ntaub ntawv rov qab, cov neeg koom nrog hnub ci kev lag luam tuaj yeem ua cov kev txiav txim siab uas yuav txhim kho kev ua haujlwm thiab kev ua haujlwm ntev ntawm kev teeb tsa hnub ci. Raws li qhov kev thov rau lub zog tauj dua tshiab txuas ntxiv mus ntxiv, qhov tseem ceeb ntawm kev xaiv lub hnub ci rov qab yuav tsuas yog nce ntxiv kom ntseeg tau tias lub hnub ci thev naus laus zis tseem yog lub zog siv tau thiab siv tau rau yav tom ntej.
