Ntau tus neeg paub tias txoj kev suav ntawm photovoltaic fais fab nroj tsuag tsim hluav taws xob yog qhov theoretical txhua xyoo lub zog tsim hluav taws xob=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 kev cuam tshuam ntawm ntau yam, lub zog tsim hluav taws xob ntawm photovoltaic fais fab nroj tsuag yog qhov tseeb tsis ntau, thiab qhov tseeb txhua xyoo lub zog tsim hluav taws xob=theoretical txhua xyoo lub zog tsim * lub zog tsim hluav taws xob tiag tiag. Yog li muaj pes tsawg yam cuam tshuam rau lub zog tsim hluav taws xob ntawm photovoltaic fais fab nroj tsuag?
1. Hnub ci hluav taws xob
Nyob rau hauv cov ntaub ntawv ntawm ib tug tej yam kev hloov dua siab tshiab efficiency ntawm solar cell Cheebtsam, lub zog tsim ntawm lub photovoltaic system yog txiav txim los ntawm kev siv ntawm lub hnub lub hluav taws xob. Lub hnub ci hluav taws xob siv zog thiab cov yam ntxwv spectral hloov nrog cov xwm txheej huab cua.
2. Lub inclination lub kaum sab xis ntawm lub hnub ci cell module
Rau tag nrho cov hnub ci hluav taws xob ntawm lub dav hlau inclined thiab txoj cai ncaj-divergent sib cais ntawm lub hnub ci hluav taws xob, tag nrho cov hnub ci hluav taws xob Ht ntawm lub dav hlau inclined yog tsim los ntawm cov hluav taws xob ncaj qha hnub ci Hbt ntuj tawg Hdt thiab hauv av reflected hluav taws xob Hrt.
Ht=Hbt plus Hdt plus Hrt
3. Kev ua tau zoo ntawm lub hnub ci cell modules
Raws li peb txhua tus paub, silicon yog cov khoom siv tseem ceeb ntawm lub hnub ci photovoltaic hlwb, yog li nws cov kev hloov pauv ib txwm yog qhov tseem ceeb txwv kev txhim kho ntxiv ntawm tag nrho kev lag luam. Tam sim no, qhov kev hloov pauv ntawm cov ntaub ntawv silicon tau ua tiav ntau dua 35 feem pua hauv chav kuaj, uas yog khi kom txo tau cov nqi hluav taws xob hnub ci.
4. 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; thaum qhov sib xyaw ua ke tuaj yeem ncav cuag ntau dua 8 feem pua , thiab tus qauv ntawm Tuam Tshoj Kev Tsim Kho Kev Tsim Kho Standardization Association yog tsawg dua 10 feem pua. Yog li ntawd, txhawm rau txo qis kev sib xyaw ua ke, kev saib xyuas yuav tsum tau them rau:
1) Cov khoom uas muaj tib yam tam sim no yuav tsum nruj me ntsis xaiv hauv series ua ntej lub chaw nres tsheb fais fab raug teeb tsa.
2) Cov yam ntxwv attenuation ntawm cov khoom yog zoo ib yam li qhov ua tau. Raws li lub teb chaws tus qauv GB/T--9535, lub siab tshaj plaws tso zis hwj chim ntawm lub hnub ci cell module yog kuaj tom qab qhov kev xeem nyob rau hauv cov kev cai, thiab nws attenuation yuav tsum tsis txhob ntau tshaj 8 feem pua. 3: Kev rho tawm diodes qee zaum tsim nyog.
5. Cov yam ntxwv kub
Thaum qhov kub thiab txias nce li 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-circuit tam sim no nce 0.04 feem pua. Txhawm rau kom tsis txhob muaj kev cuam tshuam ntawm qhov kub thiab txias ntawm lub zog tsim hluav taws xob, cov khoom yuav tsum tau ua kom muaj cua zoo.
6. Plua plav
Plua plav hauv qhov chaw nres tsheb fais fab tuaj yeem ua rau poob txog li 6 feem pua! Yog li ntawd, cov khoom yuav tsum tau so kom nquag plias.
7. Qhov siab tshaj plaws tso zis hluav taws xob taug qab (MPPT)
Los ntawm qhov kev xav ntawm daim ntawv thov hnub ci cell, lub npe hu ua daim ntawv thov yog kev taug qab ntawm qhov siab tshaj plaws tso zis hluav taws xob taw tes ntawm lub hnub ci cell. MPPT kev ua haujlwm ntawm daim phiaj-txuas txuas yog ua tiav hauv inverter.
8. Kab 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 xov hlau uas muaj hluav taws xob zoo yuav tsum siv rau hauv kev tsim, thiab cov xov hlau yuav tsum muaj txoj kab uas hla txaus. Kev tsim kho tsis pub txiav cov ces kaum. Thaum lub sij hawm tu system, tshwj xeeb yuav tsum tau them rau seb cov connectors thiab terminals yog ruaj.
9. Roj teeb efficiency (kev ywj pheej system)
Ib qho kev ywj pheej photovoltaic system yuav tsum tau siv lub roj teeb, thiab kev them nyiaj thiab kev tawm dag zog ntawm lub roj teeb ncaj qha cuam tshuam rau kev ua haujlwm ntawm lub cev, uas yog, nws yuav cuam tshuam rau lub zog tsim hluav taws xob ntawm kev ywj pheej. Feem ntau hais lus, qhov ua tau zoo ntawm cov roj ntsha lead-acid yog li 80 feem pua; Kev ua haujlwm ntawm lithium phosphate roj teeb yog ntau tshaj 90 feem pua.
10. Kev ua haujlwm ntawm cov maub los thiab photovoltaic inverter
Qhov hluav taws xob poob ntawm qhov kev them nqi thiab kev tawm hluav taws xob ntawm tus maub los yuav tsum tsis pub tshaj 5 feem pua ntawm qhov system voltage. Kev ua tau zoo ntawm daim phiaj-txuas photovoltaic inverters tam sim no ntau dua 95 feem pua, tab sis qhov no yog qhov xwm txheej.
