Txoj kev suav ntawm photovoltaic fais fab tuag muaj peev xwm yog raws li hauv qab no:
Theoretical txhua xyoo fais fab tiam=tag nrho txhua xyoo nruab nrab hnub ci hluav taws xob * tag nrho cov roj teeb cheeb tsam * photoelectric conversion efficiency
Txawm li cas los xij, vim muaj ntau yam, lub zog tsim hluav taws xob ntawm photovoltaic fais fab nroj tsuag yog qhov tseeb tsis ntau.
Kev tsim hluav taws xob txhua xyoo tiag tiag=theoretical txhua xyoo lub zog tsim * kev tsim hluav taws xob tiag tiag
Yog li dab tsi yog yam uas cuam tshuam rau lub zog tsim hluav taws xob ntawm photovoltaic fais fab nroj tsuag, cia peb coj koj los nkag siab.
1. Lub hnub ci hluav taws xob ntau npaum li cas
Lub hnub ci cell module yog ib qho cuab yeej uas hloov lub hnub ci zog rau hauv hluav taws xob hluav taws xob, thiab kev siv hluav taws xob hluav taws xob ncaj qha cuam tshuam rau cov hluav taws xob tsim tawm.
2. Lub kaum sab xis ntawm lub hnub ci cell module
Cov ntaub ntawv tau txais los ntawm qhov chaw nres tsheb huab cua feem ntau yog cov hnub ci hluav taws xob ntawm lub dav hlau kab rov tav, uas yog hloov mus rau cov hluav taws xob hluav taws xob ntawm lub dav hlau inclined ntawm photovoltaic array los xam lub zog tsim hluav taws xob ntawm photovoltaic system. Qhov zoo tshaj plaws inclination muaj feem xyuam rau lub latitude ntawm qhov project qhov chaw. Kwv yees qhov txiaj ntsig ntawm kev paub yog raws li hauv qab no:
A. Latitude 0 degree -25 degree, lub inclination lub kaum sab xis yog sib npaug rau latitude
B. Latitude yog 26 degree -40 degree, thiab inclination yog sib npaug rau latitude ntxiv rau 5 degree -10 degree
C. Lub latitude yog 41 degree -55 degree, thiab inclination yog sib npaug rau latitude ntxiv rau 10 degree -15 degree
3. Conversion efficiency ntawm solar cell modules
Photovoltaic modules yog qhov tseem ceeb tshaj plaws rau kev tsim hluav taws xob. Tam sim no, kev hloov dua siab tshiab ntawm polycrystalline silicon modules ntawm thawj-kab hom ntawm kev ua lag luam feem ntau yog siab dua 16 feem pua, thiab kev hloov dua siab tshiab ntawm monocrystalline silicon feem ntau yog siab dua 17 feem pua.
4. Qhov System Poob
Zoo li txhua yam khoom, thaum lub sijhawm 25-xyoo lub neej voj voog ntawm photovoltaic fais fab nroj tsuag, kev ua tau zoo ntawm cov khoom siv thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob yuav maj mam txo, thiab lub zog tsim hluav taws xob yuav txo qis xyoo los ntawm xyoo. Ntxiv nrog rau cov txheej txheem kev laus no, kuj tseem muaj ntau yam xws li qhov zoo ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, kev teeb tsa hauv Circuit Court, plua plav, kev poob qis, thiab cable poob.
Feem ntau, lub zog tsim hluav taws xob ntawm lub kaw lus txo qis li 5 feem pua hauv peb xyoos, thiab lub zog tsim hluav taws xob txo qis rau 80 feem pua tom qab 20 xyoo.
1. Kev sib xyaw ua ke poob
Txhua qhov kev sib txuas ntawm series yuav ua rau poob tam sim no vim qhov sib txawv ntawm cov khoom tam sim no; kev sib txuas ua ke yuav ua rau tsis muaj hluav taws xob vim qhov sib txawv ntawm qhov sib txawv ntawm cov khoom; thiab qhov kev poob ua ke tuaj yeem ncav cuag ntau dua 8 feem pua.
Yog li ntawd, txhawm rau txhawm rau txo qhov kev sib xyaw ua ke, peb yuav tsum ua tib zoo saib rau:
1) Cov khoom siv nrog tib lub sijhawm tam sim no yuav tsum nruj me ntsis xaiv hauv cov koob ua ntej kev teeb tsa ntawm lub chaw nres tsheb fais fab.
2) Cov yam ntxwv attenuation ntawm cov khoom yog zoo ib yam li qhov ua tau.
2. Plua plav npog
Ntawm tag nrho cov ntau yam uas cuam tshuam rau tag nrho lub zog tsim muaj peev xwm ntawm photovoltaic fais fab nroj tsuag, hmoov av yog tus naj npawb ib tus neeg tua neeg. Cov kev cuam tshuam tseem ceeb ntawm plua plav photovoltaic fais fab nroj tsuag yog:
1) Los ntawm shading lub teeb mus txog lub module, nws cuam tshuam rau lub zog tsim;
2) cuam tshuam cov cua kub dissipation, yog li cuam tshuam rau kev hloov dua siab tshiab;
3) Cov plua plav nrog cov kua qaub thiab alkali tso rau ntawm qhov chaw ntawm lub sijhawm ntev, uas ua rau lub rooj tsavxwm ntog thiab ua rau lub rooj tsavxwm nto tsis sib xws, uas yog qhov tsim nyog rau kev sib txuas ntxiv ntawm cov plua plav thiab ua rau muaj qhov sib txawv. reflection ntawm lub hnub ci.
Yog li ntawd, cov khoom yuav tsum tau wiped huv si ib ntus. Tam sim no, kev ntxuav ntawm photovoltaic fais fab nroj tsuag feem ntau suav nrog peb txoj kev: sprinkler, phau ntawv tu, thiab neeg hlau.
3. Cov yam ntxwv kub
Thaum qhov kub thiab txias nce los ntawm 1 degree, lub crystalline silicon hnub ci cell: lub siab tshaj plaws tso zis zog txo los ntawm 0.04 feem pua, qhov qhib Circuit Court voltage txo los ntawm 0.04 feem pua ({ {5}}mv/degree ), thiab qhov luv luv tam sim no nce 0.04 feem pua. Txhawm rau txo qhov cuam tshuam ntawm qhov kub thiab txias ntawm lub zog tsim hluav taws xob, cov modules yuav tsum tau ua kom cua zoo.
4. Kab thiab transformer poob
Cov kab poob ntawm DC thiab AC circuits ntawm lub kaw lus yuav tsum tswj tsis pub dhau 5 feem pua. Vim li no, cov hlau uas muaj hluav taws xob zoo yuav tsum tau siv rau hauv kev tsim, thiab cov hlau yuav tsum muaj txoj kab uas hla txaus. Thaum lub sij hawm tu system, tshwj xeeb yuav tsum tau them rau seb cov connectors thiab terminals yog ruaj.
5. Inverter efficiency
Vim tias lub inverter muaj cov khoom siv hluav taws xob xws li inductors, transformers thiab IGBTs, MOSFETs, thiab lwm yam, kev poob yuav tshwm sim thaum lub sijhawm ua haujlwm. Cov hlua inverter dav dav yog 97-98 feem pua, qhov nruab nrab ntawm inverter efficiency yog 98 feem pua, thiab transformer efficiency yog 99 feem pua.
6. Duab ntxoov ntxoo, daus npog
Hauv qhov chaw nres tsheb fais fab, yog tias muaj cov tsev siab nyob ib puag ncig, nws yuav ua rau cov duab ntxoov ntxoo rau cov khoom, thiab yuav tsum tau zam kom ntau li ntau tau hauv kev tsim. Raws li lub hauv paus ntsiab lus ntawm Circuit Court, thaum lub Cheebtsam txuas nrog nyob rau hauv series, tam sim no yog txiav txim los ntawm qhov tsawg tshaj plaws block, yog li yog hais tias muaj ib tug duab ntxoov ntxoo ntawm ib lub block, nws yuav cuam tshuam rau lub zog tsim ntawm cov khoom. Thaum muaj daus ntawm cov khoom, nws tseem yuav cuam tshuam rau lub zog tsim hluav taws xob thiab yuav tsum tau muab tshem tawm sai li sai tau.
