Qhov System Cheebtsam
Ntxiv rau lub hnub ci vaj huam sib luag, muaj lwm yam tseem ceeb ntawm lub tshuab hluav taws xob photovoltaic uas feem ntau hu ua "sib npaug ntawm qhov system" lossis BOS. Cov khoom no muaj xws li inverters, racking, thaiv, txuas, disconnects, Circuit Court breakers thiab hluav taws xob ntsuas.
Hnub Ci Vaj Huam Sib Luag
Lub hnub ci vaj huam sib luag muaj ntau lub hnub ci nrog cov khoom siv semiconductor encapsulated hauv cov khoom siv los tiv thaiv ib puag ncig. Cov khoom no tso cai rau lub cell kom ntes lub teeb, lossis tshwj xeeb tshaj yog, cov photons los ntawm lub hnub thiab hloov lawv lub zog rau hauv hluav taws xob muaj txiaj ntsig los ntawm cov txheej txheem hu ua cov nyhuv photovoltaic. Sab illuminated ntawm lub vaj huam sib luag tseem muaj cov txheej tiv thaiv kev cuam tshuam kom txo qis qhov poob vim kev xav. Feem ntau ntawm cov hnub ci vaj huam sib luag tsim tawm thoob ntiaj teb yog tsim los ntawm crystalline silicon, uas muaj qhov theoretical efficiency txwv ntawm 33 feem pua rau hloov lub hnub lub zog rau hauv hluav taws xob.
Inverters
Inverter yog ib qho khoom siv hluav taws xob uas lees txais hluav taws xob tam sim no hauv daim ntawv ntawm tam sim no ncaj qha (DC) thiab hloov mus rau qhov hloov pauv tam sim no (AC). Rau lub hnub ci zog, qhov no txhais tau tias DC tam sim no los ntawm lub hnub ci array yog pub los ntawm inverter uas hloov nws mus rau AC. Qhov kev hloov pauv no yog tsim nyog los ua haujlwm feem ntau cov khoom siv hluav taws xob lossis cuam tshuam nrog cov kab hluav taws xob. Inverters yog qhov tseem ceeb rau yuav luag txhua lub hnub ci zog thiab feem ntau yog cov khoom kim tshaj plaws tom qab lub hnub ci vaj huam sib luag lawv tus kheej.
Racking
Racking yog hais txog lub mounting apparatus uas kho lub hnub ci array rau hauv av los yog ru tsev. Feem ntau tsim los ntawm cov hlau lossis txhuas, cov cuab yeej siv kho tshuab kho lub hnub ci vaj huam sib luag nyob rau hauv qhov chaw nrog rau qib siab ntawm precision. Racking systems yuav tsum tau tsim los tiv thaiv huab cua huab cua xws li nag xob nag cua los yog cua daj cua dub cua nrawm thiab/lossis cov daus loj heev.
Cov khoom seem ntawm lub hnub ci PV system muaj xws li kev sib txuas, kev sib txuas, kev sib tsoo, cov ntsuas thiab cov xaim. Lub hnub ci vaj huam sib luag, raws li lub npe qhia, muab ob lossis ntau qhov hluav taws xob cables rau hauv ib qho loj dua. Combiners feem ntau suav nrog fuses rau kev tiv thaiv thiab siv rau txhua qhov nruab nrab mus rau qhov loj thiab siv hluav taws xob hnub ci arrays. Disconnects yog cov rooj vag hluav taws xob lossis cov keyboards uas tso cai rau kev txiav tawm ntawm ib qho hluav taws xob. Feem ntau siv rau ntawm ob sab ntawm lub inverter, uas yog "DC disconnect" thiab "AC disconnect" cov cuab yeej no muab hluav taws xob cais tawm thaum lub inverter xav tau los nruab lossis hloov. Circuit Court breakers los yog breakers tiv thaiv hluav taws xob systems los ntawm tam sim no los yog surges. Tsim los ua kom tau txais txiaj ntsig thaum tam sim no nce mus txog qhov nyiaj tau los, cov khoom tawg tuaj yeem ua haujlwm manually, ua raws li kev sib txuas ntxiv. Lub ntsuas hluav taws xob ntsuas lub zog uas dhau los ntawm nws thiab feem ntau siv los ntawm cov tuam txhab hluav taws xob hluav taws xob los ntsuas thiab them cov neeg siv khoom. Rau lub hnub ci PV systems, ib qho tshwj xeeb bi-directional hluav taws xob ntsuas yog siv los ntsuas ob qho tib si lub zog los ntawm kev siv hluav taws xob, thiab lub zog tawm ntawm lub hnub ci PV system. Thaum kawg, cov xaim hluav taws xob lossis hluav taws xob xa hluav taws xob thauj cov hluav taws xob hluav taws xob los ntawm thiab nruab nrab ntawm txhua qhov khoom thiab yuav tsum muaj qhov loj me kom nqa tau qhov tam sim no. Cov kab hluav taws xob raug tshav ntuj yuav tsum muaj kev tiv thaiv tiv thaiv UV, thiab cov xov hlau nqa DC tam sim no qee zaum yuav tsum tau hlau sheathing rau kev tiv thaiv ntxiv.
