Kev siv cov khoom siv hollow square thiab rectangular
Cov kav dej plaub fab yog cov khoom siv tseem ceeb thiab tseem ceeb rau cov tshuab txhawb nqa photovoltaic vim nws cov qauv zoo heev thiab kev siv nyiaj tsawg. Youfa hom kav dej hlau plaub fab siv dav hauv cov qauv txhawb nqa hnub ci, thiab muag kub hauv Middle East thiab Africa.
Cov raj xa dej plaub fabCov khoom siv photovoltaic brackets yog siv dav hauv kev tsim cov photovoltaic brackets vim lawv cov khoom siv zoo heev thiab kev ruaj khov ntawm cov qauv. Photovoltaic bracket yog ib qho tseem ceeb ntawm lub hnub ci photovoltaic fais fab tsim hluav taws xob, feem ntau yog siv los txhawb thiab kho cov vaj huam sib luag hnub ci. Kev siv cov raj plaub fab plaub fab ua cov ntaub ntawv txhawb nqa muaj cov txiaj ntsig hauv qab no:
Lub zog siab:Lub raj duab plaub fab uas muaj qhov hla ntuag ua rau nws muaj zog thaum raug cov khoom thauj ntev thiab hla ntuag, ua rau nws tiv taus cov yam ntxwv sab nraud xws li cua hlob thiab daus hlob.
Kev ruaj khov zoo:Tus qauv tsim ntawm lub raj plaub fab ua kom muaj kev ruaj khov zoo tom qab kev teeb tsa, txo qhov kev hloov pauv los ntawm cov zog sab nraud.
Yooj yim rau kev ua:Kev ua cov raj plaub fab thiab plaub fab yog qhov yooj yim heev, thiab tuaj yeem txiav, vuam, thiab kho qhov chaw raws li qhov xav tau tiag tiag, ua rau kev teeb tsa thiab kev saib xyuas yooj yim.
Sib dua:Piv rau lwm cov ntaub ntawv, cov kav dej plaub fab plaub fab sib dua, ua rau lawv yooj yim dua rau kev thauj mus los thiab teeb tsa, thiab txo cov nqi tsim kho.
Kev tiv thaiv xeb:Cov kav dej plaub fab uas tau kho qhov chaw muaj kev tiv thaiv corrosion zoo thiab tuaj yeem hloov kho rau ntau yam huab cua, ua rau lawv lub neej ntev dua.
Kev Lag Luam:Tus nqi tsim khoom ntawm cov raj plaub fab thiab plaub fab yog qhov qis, tsim nyog rau cov ntawv thov loj, thiab tuaj yeem txo qhov nqi tag nrho ntawm cov tshuab hluav taws xob photovoltaic.
Kev pab cuam tom qab muag zoo:Youfa hom muaj lub koob npe zoo hauv kev ua lag luam, muab kev pabcuam tom qab muag zoo kom ntseeg tau tias cov neeg siv khoom txaus siab thaum siv.
Yog li ntawd, daim ntawv thov ntawm cov raj plaub fab plaub fab hauv kev txhawb nqa photovoltaic tsis yog tsuas yog txhim kho kev ua tau zoo ntawm cov kev txhawb nqa, tab sis kuj txhawb nqa kev txhim kho ntawm kev lag luam photovoltaic.
