Raws li peb txhua tus paub, 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, tab sis vim muaj ntau yam, lub zog tiag tiag ntawm photovoltaic. fais fab nroj tsuag tsis ntau npaum li, qhov tseeb xyoo fais fab tiam=theoretical txhua xyoo fais fab tiam * lub zog tsim efficiency. Cia peb tsom mus rau kaum qhov tseem ceeb uas cuam tshuam rau lub zog tsim hluav taws xob ntawm photovoltaic fais fab nroj tsuag!
1. Lub hnub ci hluav taws xob ntau npaum li cas
Thaum lub zog hloov dua siab tshiab ntawm lub hnub ci hluav taws xob tsis tu ncua, lub zog tsim hluav taws xob ntawm photovoltaic system yog txiav txim siab los ntawm kev siv hluav taws xob ntawm lub hnub.
Kev siv hluav taws xob ntawm lub hnub ci hluav taws xob los ntawm photovoltaic system tsuas yog kwv yees li 10 feem pua (hnub ci kev ua haujlwm ntawm lub hnub ci, kev sib xyaw ua ke poob, plua plav poob, tswj inverter poob, kab poob, roj teeb efficiency)
Lub zog tsim hluav taws xob ntawm photovoltaic fais fab nroj tsuag yog ncaj qha ntsig txog cov hnub ci hluav taws xob, thiab lub hnub ci hluav taws xob siv hluav taws xob thiab cov yam ntxwv spectral hloov nrog cov xwm txheej huab cua.
2. 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 lub hauv paus ntsiab lus ntawm kev sib cais ncaj qha 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 lub hnub ci hluav taws xob ncaj qha Hbt ntuj tawg nyiaj Hdt thiab hauv av. reflected hluav taws xob npaum li cas Hrt.
Ht=Hbt plus Hdt plus Hrt
3. Kev ua haujlwm ntawm lub hnub ci cell modules
Txij li thaum pib ntawm lub xyoo pua no, kuv lub teb chaws lub hnub ci photovoltaic tau nkag mus rau lub sijhawm ntawm kev loj hlob sai, thiab kev ua haujlwm ntawm lub hnub ci hlwb tau raug txhim kho tas li. Nrog kev pab los ntawm nanotechnology, kev hloov pauv ntawm cov ntaub ntawv silicon yuav ncav cuag 35 feem pua nyob rau yav tom ntej, uas yuav dhau los ua "kev hloov pauv" hauv kev tsim hluav taws xob hnub ci. Kev sib deev".
Cov khoom siv tseem ceeb ntawm lub hnub ci photovoltaic hlwb yog silicon, yog li kev hloov pauv ntawm cov khoom siv silicon yeej ib txwm yog qhov tseem ceeb txwv kev txhim kho ntxiv ntawm tag nrho kev lag luam. Lub classical theoretical txwv rau kev hloov ntawm cov ntaub ntawv silicon yog 29 feem pua. Cov ntaub ntawv teev tseg hauv chav kuaj yog 25 feem pua, thiab cov cuab yeej no tau muab tso rau hauv kev lag luam.
Labs muaj peev xwm twb rho tawm high-purity silicon ncaj qha los ntawm silica tsis hloov nws mus rau nws yog xim hlau silicon thiab ces rho tawm silicon los ntawm nws. Qhov no tuaj yeem txo cov kev sib txuas nruab nrab thiab txhim kho kev ua haujlwm.
Kev sib koom ua ke thib peb tiam nanotechnology nrog cov thev naus laus zis uas twb muaj lawm tuaj yeem nce qhov hloov pauv ntawm cov ntaub ntawv silicon rau ntau dua 35 feem pua. Yog tias nws tau muab tso rau hauv kev lag luam loj, nws yuav txo tau tus nqi ntawm lub hnub ci hluav taws xob ntau. Qhov xwm zoo yog tias cov cuab yeej siv no "tau ua tiav hauv chav kuaj thiab tos rau cov txheej txheem ntawm kev lag luam".
4. 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;
Ib qho kev sib txuas ua ke yuav ua rau tsis muaj hluav taws xob vim qhov sib txawv ntawm qhov sib txawv ntawm cov khoom;
Kev sib xyaw ua ke tuaj yeem ncav cuag ntau dua 8 feem pua , thiab tus qauv ntawm Tuam Tshoj Engineering Kev Tsim Kho Standardization Association tau teev tseg tias nws tsawg dua 10 feem pua.
Daim ntawv ceeb toom:
(1) Txhawm rau txo qis kev sib xyaw ua ke, 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 sib xws yog raws 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 xov tooj ntawm tes yog kuaj tom qab kuaj raws li cov kev cai, thiab nws attenuation yuav tsum tsis txhob ntau tshaj 8 feem pua.
(3) Thaiv diodes qee zaum tsim nyog.
5. 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 kom tsis txhob muaj qhov kub thiab txias ntawm lub zog tsim hluav taws xob, cov ntsiab lus yuav tsum tau ua kom muaj cua zoo.
6. Plua plav
Plua plav poob hauv cov chaw nres tsheb fais fab tuaj yeem ncav cuag 6 feem pua! Cheebtsam yuav tsum tau wiped nquag.
7. MPPT taug qab
Qhov siab tshaj plaws tso zis hluav taws xob mus txog qhovtwg (MPPT) Los ntawm kev xaav ntawm daim ntawv thov hnub ci, 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. Tsis ntev los no, qee qhov kev tshawb fawb tau muab tso rau hauv DC lub thawv sib txuas.
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 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. Kev tsim kho tsis raug tso cai txiav cov fab. Thaum lub sij hawm kho qhov system, tshwj xeeb yuav tsum tau them nyiaj rau seb qhov kev pab cuam plug-in txuas thiab seb cov terminals puas ruaj khov.
9. Controller thiab inverter efficiency
Qhov hluav taws xob poob ntawm kev them nyiaj 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 inverter yog tam sim no ntau dua 95 feem pua, tab sis qhov no yog qhov xwm txheej.
10. Roj teeb efficiency (kev ywj pheej system)
Ib qho kev ywj pheej photovoltaic system yuav tsum siv lub roj teeb. Kev them nyiaj thiab tso tawm kev ua haujlwm ntawm lub roj teeb ncaj qha cuam tshuam rau kev ua haujlwm ntawm lub kaw lus, uas yog, nws cuam tshuam rau lub zog tsim hluav taws xob ntawm kev ywj pheej, tab sis qhov no tseem tsis tau nyiam txhua tus neeg. Kev ua haujlwm ntawm txhuas-acid roj teeb yog 80 feem pua; qhov ua tau zoo ntawm lithium phosphate roj teeb yog ntau tshaj 90 feem pua.
