Muaj peb yam tseem ceeb rau kev ua haujlwm hluav taws xob ntawm photovoltaic modules:
Thawj qhov yog lub zog siab Pm: Peak zog yog hais txog lub zog ntawm lub hnub ci module kuaj nyob rau hauv cov xwm txheej ntawm lub hnub ci hluav taws xob siv ntawm 1000W / ㎡ thiab qhov ntsuas kub ntawm 25 degree. Nws yog sib npaug rau lub ncov fais fab voltage multiplied los ntawm lub ncov fais fab tam sim no.
Qhov thib ob yog qhov qhib Circuit Court voltage Voc: nws hais txog lub davhlau ya nyob twg voltage ntawm lub roj teeb nyob rau hauv lub xeev qhib Circuit Court, uas yog hu ua qhib Circuit Court voltage. Qhov qhib Circuit Court voltage ntawm lub hnub ci vaj huam sib luag ntsuas ncaj qha nrog lub multimeter yam tsis muaj kev thauj khoom yog qhov voltage ntawm ob qho kawg. Cov yam ntxwv cuam tshuam ntawm qhov qhib hluav taws xob hluav taws xob yog lub teeb siv, qhov kub thiab txias, thiab cov khoom siv.
Qhov thib peb yog hais txog qhov luv-circuit tam sim no lsc: qhov luv-circuit tam sim no yog hais txog tus nqi tam sim no tom qab cov ncej zoo thiab qhov tsis zoo yog luv luv Circuit Court. Qhov ntau yam tam sim no tuaj yeem kuaj ncaj qha los ntawm kev siv multimeter los txiav txim qhov zoo thiab qhov tsis zoo ntawm lub hnub ci vaj huam sib luag. Cov yam ntxwv cuam tshuam ntawm qhov luv-circuit tam sim no yog cheeb tsam, lub teeb siv, thiab kub.
Dab tsi yog STC tus qauv kuaj rau cov cell photovoltaic?
Photovoltaic cells yog cov khoom siv uas hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob thiab tau siv dav hauv photovoltaic panels thiab photovoltaic fais fab chaw nres tsheb. Cov txheej txheem kuaj mob rau cov cell photovoltaic yog cov txheej txheem txheej txheem tsim los xyuas kom meej qhov sib piv ntawm cov ntsuas kev ua haujlwm ntawm cov cell photovoltaic. Nkag siab txog cov qauv kev sim rau cov cell photovoltaic yog qhov tseem ceeb rau kev ntsuas lawv qhov kev ua tau zoo.
Lub International Electrotechnical Commission (IEC) tau tsim cov qauv kev sim rau cov kab hluav taws xob photovoltaic, thaum STC (Standard Test Conditions) cov qauv ntsuas ntsuas muaj xws li: hnub ci irradiance ntawm 1000W / ㎡, spectrum ntawm AM (atmospheric mass) 1.5, thiab kub ntawm lub hnub ci. vaj huam sib luag ntawm 25 degree.
Huab cua zoo (AM) yog hais txog qhov sib piv ntawm qhov kev ncua deb ntawm lub hnub ci los ntawm cov cua mus rau qhov luv tshaj plaws uas nws yuav siv mus txog hauv av.
Qhov kev sim no tuaj yeem muab qhov chaw sim ncaj ncees thiab ncaj ncees rau ntau hom photovoltaic hlwb, kom ntseeg tau qhov sib piv ntawm lawv cov ntsuas kev ua tau zoo.
Hauv kev siv cov tswv yim, STC tus qauv ntsuas cov xwm txheej feem ntau yog siv los ntsuas cov ntsuas kev ua tau zoo xws li lub zog ncov, qhov siab tshaj plaws tam sim no, qhov hluav taws xob siab tshaj plaws, thiab luv-circuit tam sim no ntawm cov cell photovoltaic.
NOCT kuaj rau photovoltaic modules yog dab tsi?
NOCT tus qauv ntsuas rau cov cell photovoltaic yog hais txog qhov ntsuas kub ntawm lub xov tooj ntawm tes, uas yog siv los ntsuas kev ua haujlwm ntawm lub cell photovoltaic raws li cov qauv txheej txheem.
Cov qauv kev sim rau NOCT suav nrog: hnub ci irradiance ntawm 800W / ㎡, spectrum ntawm AM1.5, ambient kub ntawm 20 degree, thiab cua ceev ntawm 1m / s.
NOCT kuaj cov xwm txheej tuaj yeem ua rau tib neeg nkag siab ntau dua qhov kev ua haujlwm ntawm cov cell photovoltaic hauv qhov chaw siv tiag tiag. Piv nrog rau STC tus qauv kev kuaj mob, nws yog ze rau cov kev ua haujlwm tiag tiag thiab tuaj yeem muab cov ntaub ntawv tseem ceeb rau kev xaiv, tsim, thiab siv cov cell photovoltaic.
