Nws yog qhov yooj yim heev rau nruab ib lub kaw lus uas tuaj yeem tsim hluav taws xob. Muaj tsib yam tseem ceeb uas xav tau:
1. Hnub ci vaj huam sib luag
2. Cov khoom siv bracket
3. Cov kab
4. PV daim phiaj-txuas inverter
5. Meter ntsia los ntawm lub tuam txhab daim phiaj
Xaiv lub hnub ci vaj huam sib luag (module)
Tam sim no, hnub ci hlwb ntawm kev ua lag luam tau muab faib ua amorphous silicon thiab crystalline silicon. Crystalline silicon tuaj yeem muab faib ua polycrystalline silicon thiab monocrystalline silicon. Lub photoelectric conversion efficiency ntawm peb cov ntaub ntawv yog: monocrystalline silicon> polycrystalline silicon> amorphous silicon. Crystalline silicon (monocrystalline silicon thiab polycrystalline silicon) yeej tsis tsim tam sim no nyob rau hauv lub teeb tsis muaj zog, thiab amorphous silicon muaj lub teeb pom kev zoo (muaj zog me ntsis hauv lub teeb tsis muaj zog). Yog li ntawd, feem ntau, monocrystalline silicon los yog polycrystalline silicon solar cell cov ntaub ntawv yuav tsum tau siv.
2. Txhawb kev xaiv
Hnub ci photovoltaic bracket yog ib qho tshwj xeeb bracket tsim los rau kev tso, txhim kho thiab kho lub hnub ci vaj huam sib luag hauv hnub ci photovoltaic lub zog tsim hluav taws xob. Cov ntaub ntawv dav dav yog aluminium alloy thiab stainless hlau, uas muaj lub neej ntev kev pab cuam tom qab kub galvanizing. Kev txhawb nqa feem ntau muab faib ua ob pawg: ruaj thiab tsis siv neeg taug qab. Tam sim no, qee qhov kev txhawb nqa ruaj khov hauv khw kuj tuaj yeem hloov kho raws li lub caij nyoog hloov pauv ntawm lub hnub lub teeb. Ib yam li thaum nws tau tsim thawj zaug, txoj kab nqes ntawm txhua lub hnub ci vaj huam sib luag tuaj yeem hloov kho kom haum rau qhov sib txawv ntawm lub teeb los ntawm kev txav cov fasteners, thiab lub hnub ci vaj huam sib luag tuaj yeem raug kho kom raug ntawm txoj hauj lwm teev los ntawm kev nruj dua.
3. Kev xaiv cable
Raws li tau hais los saum no, lub inverter hloov DC tsim los ntawm lub hnub ci vaj huam sib luag rau hauv AC, yog li ib feem ntawm lub hnub ci vaj huam sib luag mus rau DC kawg ntawm lub inverter yog hu ua DC sab (DC sab), thiab DC sab yuav tsum tau siv tshwj xeeb. photovoltaic DC cable (DC cable). Tsis tas li ntawd, rau kev siv photovoltaic, lub hnub ci zog siv feem ntau siv rau hauv ib puag ncig hnyav, xws li muaj zog UV, ozone, kub hloov pauv thiab tshuaj yaig, uas qhia tias photovoltaic cables yuav tsum muaj huab cua zoo tshaj plaws, UV thiab ozone corrosion kuj, thiab tuaj yeem tiv taus ntau yam kev hloov pauv kub.
4. Kev xaiv ntawm inverter
Ua ntej tshaj plaws, xav txog kev taw qhia ntawm cov hnub ci vaj huam sib luag. Yog tias lub hnub ci vaj huam sib luag tau teem rau hauv ob qho kev qhia tib lub sijhawm, nws raug nquahu kom siv dual MPPT taug qab inverter (dual MPPT). Rau lub sijhawm tam sim no, nws tuaj yeem nkag siab tias yog ob lub core processor, thiab txhua tus tub ntxhais ua haujlwm rau kev suav hauv ib qho kev coj. Tom qab ntawd xaiv lub inverter nrog tib specification raws li lub peev xwm ntsia.
5. Metering meters (ob txoj kev meters) ntsia los ntawm lub tuam txhab daim phiaj
Yog vim li cas rau kev txhim kho ob-txoj kev hluav taws xob ntsuas hluav taws xob yog tias cov hluav taws xob tsim los ntawm photovoltaic tsis tuaj yeem siv los ntawm cov neeg siv, thaum cov hluav taws xob ntxiv yuav tsum tau xa mus rau hauv daim phiaj, thiab cov ntsuas hluav taws xob yuav tsum ntsuas tus lej. Thaum lub tshuab hluav taws xob photovoltaic tsis tuaj yeem ua tau raws li qhov xav tau, nws yuav tsum siv hluav taws xob ntawm daim phiaj, uas yuav tsum ntsuas lwm tus lej. Ib qho tib si watt teev ntsuas ntsuas tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, yog li ntse watt teev ntsuas nrog bidirectional watt teev ntsuas ntsuas ntsuas tau siv.
