Ib txoj hlua IV nkhaus tuaj yeem muab cov ntaub ntawv hauv qab no:
1. Kev ntsuas ntawm txoj hlua qhib Circuit Court voltage (Voc) thiab luv luv tam sim no (Isc).
2. Kev ntsuas ntawm max zog voltage (Vmpp), tam sim no (Impp), thiab max zog (Pmax).
3. Kev ntsuas kev ua haujlwm ntawm txoj hlua.
4. Kev ntsuas ntawm module/string filling factor.
5. Kev txheeb xyuas qhov teeb meem ntawm module / hlua teeb meem lossis teeb meem shading.
Ua ntej ua qhov kev ntsuam xyuas IV nkhaus, IV nkhaus ntsuas cov cuab yeej yuav tsum tau kuaj xyuas kom ntseeg tau tias nws haum rau qhov ntsuas hluav taws xob thiab tam sim no ntawm Circuit Court hauv kev sim. Ib qho kev ntsuas IV nkhaus yog ib qho kev siv tau los muab cov hlua qhib Circuit Court voltage (Voc) thiab luv luv tam sim no (Isc). Qhov twg qhov kev kuaj IV nkhaus yog ua, cais Voc thiab Isc xeem tsis tas yuav tsum tau.
Txoj hlua nyob rau hauv kev sim yuav tsum raug cais tawm thiab txuas nrog IV nkhaus ntsuas khoom. Yog hais tias lub hom phiaj ntawm IV nkhaus test tsuas yog los muab qhov tseem ceeb rau Voc thiab Isc, ces tsis tas yuav tsum ntsuas irradiance (los yog cell kub).
Muab qhov tsim nyog irradiance tej yam kev mob, ib qho IV nkhaus kev ntsuam xyuas muab ib tug txhais tau tias los soj ntsuam hais tias kev ua tau zoo ntawm ib tug PV hlua / module yog ua tau raws li qhov ntsuas (nameplate) kev ua tau zoo. PV hlua thiab array kev ntsuas kev ua tau zoo yuav tsum tau ua nyob rau hauv qhov chaw ruaj khov irradiance yam tsawg kawg yog 400 W / m2 raws li ntsuas hauv lub dav hlau ntawm array. Yog tias qhov ntsuas tau tsim los siv rau STC (lub hom phiaj yog xam lub npe phaj ntsuas lub zog ntawm cov modules / array) irradiance yuav tsum yog tsawg kawg yog 800 W / m2 raws li IEC 60904-1 IEC 61829 tus qauv yuav tsum ua raws (ntxiv rau cov ntsiab lus sau tseg saum toj no) rau qhov yuav tsum tau ua ntawm cov khoom siv tshuaj ntsuam xyuas, cov txheej txheem tshuaj xyuas, kev ntsuam xyuas, yam tsawg kawg nkaus ib puag ncig, thiab kev tshaj tawm yuav tsum tau ua rau kev ua haujlwm sab nraum IV nkhaus kuaj.
