Hnub ci modules yog qhov tseem ceeb ntawm hnub ci zog systems.
Nws txoj haujlwm yog los hloov lub hnub ci zog rau hauv lub zog hluav taws xob thiab xa mus rau lub roj teeb rau kev khaws cia kom yooj yim rau kev ua haujlwm ntawm kev thauj khoom..
Raws li ib feem tseem ceeb ntawm photovoltaic modules, lub zog tso zis ntawm cov hnub ci cables tseem ceeb heev.
Yog li, dab tsi yam yuav cuam tshuam rau lub siab tshaj plaws tso zis zog ntawm hnub ci modules?
1. Cov yam ntxwv kub ntawm hnub ci modules Photovoltaic modules feem ntau muaj peb qhov kub coefficients: qhib Circuit Court voltage, luv luv tam sim no, thiab peak zog.
Thaum kub nce, Lub zog tso zis ntawm PV modules yuav poob. Lub ncov kub coefficient ntawm mainstream crystalline silicon photovoltaic modules ntawm kev ua lag luam yog hais txog -0.38-0.44%/C, uas yog, rau txhua qhov ntsuas kub nce, lub zog tsim ntawm photovoltaic modules txo los ntawm txog 0.38%.
Qhov kub coefficient ntawm nyias zaj duab xis solar cells yog qhov zoo dua. Piv txwv, Qhov kub coefficient ntawm tooj liab hlau selenium (CIGS) yog xwb -0.1-0.3%, thiab kub coefficient ntawm cadmium (CdTe) yog hais txog -0.25%, uas yog zoo dua li ntawm crystalline silicon cell.
2. Module aging thiab attenuation Nyob rau hauv daim ntawv thov mus sij hawm ntev ntawm photovoltaic modules, yuav muaj qeeb zog attenuation. Qhov siab tshaj plaws lwj yog hais txog 3% hauv thawj xyoo, thiab tus nqi lwj txhua xyoo rau yav tom ntej 24 xyoo yog hais txog 0.7%.
Los ntawm qhov kev suav no, lub zog tiag tiag ntawm photovoltaic modules tseem tuaj yeem ncav cuag 80% ntawm thawj lub zog tom qab 25 lub yim.
3. Kev pab them nqi ntawm cov plua plav thiab nag loj-teev photovoltaic fais fab nroj tsuag feem ntau ua rau hauv cheeb tsam Gobi, qhov twg cua thiab xuab zeb kuj loj heev thiab tsis muaj nag lossis daus me ntsis. Nyob rau tib lub sijhawm, qhov zaus ntawm kev ntxuav tsis yog siab dhau.
Tom qab siv sijhawm ntev, nws yuav ua rau ib tug efficiency poob ntawm txog 8%. Cov modules tsis sib xws hauv series hnub ci modules tsis sib haum thaum txuas nrog hauv series, uas tuaj yeem piav qhia intuitively los ntawm cov nyhuv cask.
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 kev tivthaiv mismatch yuav ua rau qee lub zog poob.
Cov ntsiab lus saum toj no yog cov ntsiab lus tseem ceeb cuam tshuam rau qhov siab tshaj plaws tso zis hluav taws xob ntawm photovoltaic cell modules, uas yuav ua rau lub zog poob mus ntev.
Yog li ntawd, tom qab kev ua haujlwm thiab kev saib xyuas ntawm photovoltaic fais fab nroj tsuag yog qhov tseem ceeb heev, uas tuaj yeem txo qhov poob ntawm cov txiaj ntsig los ntawm kev ua tsis tiav.
