Ua ntej tshaj plaws, kev tsim hluav taws xob photovoltaic feem ntau txhim khu kev qha. Nws yog qhov tseeb tias lub peev xwm ntsia tau tseem nce ntxiv. Ntau thiab ntau tus neeg xav tias photovoltaic yog lub zog yav tom ntej ntawm noob neej. Txawm hais tias tus nqi yog me ntsis siab dua tam sim no, nrog kev nce qib ntawm thev naus laus zis, lub sijhawm ntawm kev siv Internet pheej yig yuav tuaj sai lossis tom qab. Txij thaum ntawd los, photovoltaics yuav ua rau kev txhim kho dav dav, uas tseem yog lub hom phiaj ntawm lub xeev los txhawb kev txhim kho lub zog.
Tam sim no, photovoltaic fais fab nroj tsuag feem ntau faib rau hauv: centralized fais fab nroj tsuag thiab faib fais fab nroj tsuag rau lub ru tsev ntawm cov tsev nyob, industrial thiab coj mus muag vaj tse, thiab lwm yam.
Nyob rau hauv xyoo tas los no, nrog rau kev ua qias tuaj ntawm ib puag ncig thiab kev txhawb zog thiab kev txhawb zog ntawm lub xeev rau lub zog tshiab, photovoltaics tau lees paub ntau dua los ntawm cov neeg. Raws li cov khoom siv nyiaj txiag hauv tsev neeg, cov chaw tsim hluav taws xob photovoltaic yog ob qho tib si huv si thiab cov peev txheej, tab sis vim Tsis muaj kev saib xyuas kev lag luam thiab qee cov tub lag luam tsis zoo, tsis zoo, ua rau lub hnab sib xyaw ua ke ntawm qhov zoo thiab qhov tsis zoo hauv kev lag luam photovoltaic. Yog li yog tias peb txiav txim siab los nqis peev, peb yuav tsum xaiv lub lag luam uas ntseeg tau li cas? Qhov no yuav tsum yog qhov teeb meem txhawj xeeb tshaj plaws rau cov neeg siv.
Lub tshuab hluav taws xob photovoltaic feem ntau saib ntawm tsib ntu:
1. Hnub ci vaj huam sib luag (hnub ci modules, kev lag luam feem ntau muab faib ua ob pawg: crystalline silicon thiab nyias-film modules); crystalline silicon modules tau muab faib ua ob pawg: monocrystalline silicon thiab amorphous silicon);
Kev xaiv hnub ci vaj huam sib luag: Ua ntej ntawm tag nrho cov, nyias-zaj duab xis modules tsis pom zoo, vim li cas koj hais li ntawd? Saib ntawm kev sib koom ua lag luam, kev ua lag luam sib koom ntawm cov yeeb yaj kiab nyias nyias yog qhov qis tshaj. Thib ob, monocrystalline modules thiab polycrystalline modules tuaj yeem xaiv tau, vim tias lawv muaj ntau lub lag luam sib koom thiab yog cov thev naus laus zis paub tab. Ob lub ntsiab lus tau lees paub rau 25 xyoo thiab lub zog tso zis tsis tsawg dua 80 feem pua ntawm thawj lub zog.
2. Photovoltaic brackets (sib faib ua ob pawg: taag brackets thiab taug qab brackets);
Kev xaiv bracket: Rau cov brackets, ruaj khov feem ntau xaiv, vim hais tias txawm hais tias cov kauj ruam taug qab twb paub lawm, cov nqi kho yuav tsum tau nyob rau theem tom ntej, thiab kev lag luam feem me me. Tom qab ntawd koj yuav tsum xaiv lub bracket ruaj khov. Lub bracket ruaj khov feem ntau yog siv kub-dip galvanized C-shaped steel brackets thiab aluminium profiles hauv khw. Nco ntsoov tias C-shaped steel brackets yuav tsum tau muab ntsia kom tsis txhob muaj qhov chaw vuam thiab lwm txoj hauv kev. Yog hais tias chav tsev orientation thiab lwm yam yuav tsum tau welded. Ua haujlwm zoo ntawm kev tiv thaiv xeb, thiab tsis tu ncua xyuas kev tiv thaiv xeb. Bracket lub neej thiab cov khoom siv lub neej yog tib yam.
3. Inverters (txoj hlua inverters, micro inverters, thiab centralized inverters);
Inverter xaiv: centralized inverters tsis haum rau me me faib tshuab; Nws yog qhov khib nyiab heev los siv micro-inverters; Feem ntau, txoj hlua inverters raug xaiv, thiab hlua inverters yog tib yam kom pom kev lag luam.
4. Cable;
Cov kab hluav taws xob photovoltaic feem ntau yog siv hauv cov tshuab faib. Cov kab hluav taws xob photovoltaic muaj cov khoom sib txawv dua li cov kab hluav taws xob zoo tib yam nyob rau hauv cov nqe lus ntawm qhov kub thiab txias, kev laus tsis kam, kev muaj peev xwm, thiab khoov. PV cables yog siv tsis hais txog ntawm DC hauv qhov system. Tsis tas yuav txhawj xeeb txog AC cable ib feem, uas feem ntau ua raws li cov cai ntawm State Grid, txwv tsis pub State Grid yuav tsis lees txais ua ntej.
5. Distribution box (combiner box)
Distribution box (combiner box) xaiv: Feem ntau, lub thawv sib txuas muaj qhov sib txawv thiab lub zog sib txuam raws li qhov sib txawv ntawm lub peev xwm. Cov kev cai yooj yim rau cov khoom me me ntawm cov khoom siv hluav taws xob faib hluav taws xob tsis yog siab, tsuav yog muaj cov khoom siv rov qab los ntawm tus kheej, kev tiv thaiv hluav taws xob hluav taws xob, riam hloov hluav taws xob, hluav taws xob hluav taws xob, thiab lwm yam. Cov kev xav tau sib txawv ntawm qhov chaw mus rau qhov chaw, raws li cov cai hauv zos.
