1. Cov yam ntxwv kub ntawm photovoltaic modules
Photovoltaic modules feem ntau muaj peb qhov kub coefficient: qhib Circuit Court voltage, luv Circuit Court tam sim no, thiab lub zog siab. Thaum qhov kub thiab txias, cov zis hluav taws xob ntawm photovoltaic modules yuav txo qis. Lub ncov kub coefficient ntawm mainstream crystalline silicon photovoltaic modules nyob rau hauv kev ua lag luam yog hais txog {{0}}.38 ~ 0.44 feem pua / degree, uas yog, raws li qhov kub thiab txias, lub zog tsim ntawm photovoltaic modules txo. Hauv txoj kev xav, rau txhua qhov ntsuas kub nce, lub zog tsim hluav taws xob txo qis li ntawm 0.38 feem pua.
Nws yog ib nqi sau cia hais tias raws li qhov kub thiab txias, lub luv luv-circuit tam sim no yuav luag tsis hloov, thaum lub qhib-circuit voltage txo, qhia tau hais tias lub ambient kub yuav ncaj qha cuam tshuam cov zis voltage ntawm lub photovoltaic module.
2. Kev laus lwj
Hauv kev siv lub sijhawm ntev, cov khoom siv yuav ua rau lub zog qeeb qeeb. Raws li tuaj yeem pom los ntawm ob daim duab hauv qab no, qhov siab tshaj plaws attenuation nyob rau hauv thawj xyoo yog hais txog 3 feem pua, thiab txhua xyoo attenuation tus nqi nyob rau hauv 24 xyoo tom ntej yog hais txog 0.7 feem pua. Raws li qhov kev suav no, lub zog tiag tiag ntawm photovoltaic modules tom qab 25 xyoo tseem tuaj yeem ncav cuag li 80 feem pua ntawm thawj lub zog.
Muaj ob lub laj thawj tseem ceeb rau kev laus attenuation:
1) Lub attenuation tshwm sim los ntawm kev laus ntawm lub roj teeb nws tus kheej yog feem ntau cuam tshuam los ntawm cov roj teeb hom thiab cov txheej txheem ntawm cov roj teeb.
2) Lub attenuation tshwm sim los ntawm kev laus ntawm cov khoom ntim yog feem ntau cuam tshuam los ntawm cov txheej txheem tsim khoom, cov khoom ntim thiab ib puag ncig siv. Ultraviolet hluav taws xob yog ib qho tseem ceeb vim li cas rau qhov tsis zoo ntawm cov khoom tseem ceeb. Lub sij hawm ntev irradiation ntawm ultraviolet rays ua rau EVA thiab daim ntawv rov qab (TPE qauv) kom muaj hnub nyoog thiab tig daj, ua rau txo qis hauv kev xa tawm ntawm lub module thiab txo lub zog. Tsis tas li ntawd, kev tawg, kub kub, xuab zeb abrasion, thiab lwm yam yog txhua yam uas ua rau kom lub zog attenuation ntawm cov khoom.
Qhov no xav kom cov tuam txhab tsim khoom nruj me ntsis tswj kev xaiv ntawm EVA thiab backplanes kom txo tau lub hwj chim attenuation ntawm cov khoom los ntawm kev laus ntawm cov khoom pab. Raws li ib tug ntawm cov thawj tuam txhab uas muag nyob rau hauv kev lag luam los daws cov teeb meem ntawm lub teeb-induced attenuation, lub teeb-induced high kub attenuation thiab muaj peev xwm-induced attenuation, Hanwha Q CELLS cia siab rau nws Q.ANTUM technology los muab anti-PID, anti-LID. thiab tiv thaiv LeTID, tiv thaiv qhov kub thiab txias, thiab kev taug qab zoo. Tra.QTM's quadruple fais fab tiam lav lav tau txais kev lees paub dav dav los ntawm cov neeg siv khoom.
3. Cov khoom pib lub teeb-induced attenuation
Thawj lub teeb-induced attenuation ntawm lub module, uas yog, lub hwj chim tso zis ntawm lub photovoltaic module muaj ib tug kuj loj poob nyob rau hauv thawj ob peb hnub ntawm kev siv, tab sis tom qab ntawd nyhav kom ruaj khov, thiab cov degree ntawm lub teeb-induced attenuation ntawm txawv. hom cell yog txawv:
Hauv P-hom (boron-doped) crystalline silicon (ib leeg siv lead ua / polycrystalline) silicon wafers, lub teeb los yog tam sim no txhaj tshuaj ua rau tsim cov boron-oxygen complexes nyob rau hauv silicon wafers, uas yuav txo tau cov haiv neeg tsawg lub neej, thiaj li hais tias ib co photogenerated carriers. yog recombined, txo cov cell efficiency, ua rau lub teeb-induced attenuation.
Txawm li cas los xij, photoelectric conversion efficiency ntawm amorphous silicon solar cells yuav poob qis hauv thawj ib nrab xyoo ntawm kev siv, thiab nws thiaj li ruaj khov ntawm li 70 feem pua rau 85 feem pua ntawm cov kev hloov pauv thawj zaug.
4. Plua plav npog
Loj-scale photovoltaic fais fab nroj tsuag feem ntau tsim nyob rau hauv cheeb tsam Gobi, qhov twg muaj kuj loj sandstorms thiab nag los nag tsawg. Nyob rau tib lub sijhawm, qhov zaus ntawm kev ntxuav tsis yog siab dhau. Tom qab siv mus ntev, nws tuaj yeem ua rau kev ua haujlwm poob li ntawm 8 feem pua.
5. Component series mismatch
Qhov tsis sib haum xeeb ntawm cov khoom hauv koob tuaj yeem piav qhia los ntawm cov nyhuv chim. Tus nqi ntawm cov dej nyob rau hauv lub thoob yog txwv los ntawm lub shortest ntoo board; thiab cov zis tam sim no ntawm photovoltaic module raug txwv los ntawm qhov qis tshaj tam sim no hauv series module. Qhov tseeb, yuav muaj qee lub zog sib txawv ntawm cov khoom, yog li qhov tsis sib haum xeeb ntawm cov khoom yuav ua rau qee lub zog poob.
