Dab tsi yog cov txheej txheem kev cai rau photovoltaic modules?
Photovoltaic modules yog ib qho tseem ceeb tshaj plaws nyob rau hauv photovoltaic systems, thiab tsim nyog photovoltaic modules yuav tsum tau raws li tej yam kev cai. National thiab kev lag luam qauv rau photovoltaic modules xav tau:
1. The service life of photovoltaic modules yuav tsum muaj ntau tshaj 25 xyoo nyob rau hauv lub chaw ua hauj lwm teev; Lub zog attenuation ntawm cov khoom yuav tsum tsis txhob qis dua 80% ntawm lub zog qub hauv 20 xyoo;
2. Cov xim saum npoo ntawm lub roj teeb ntawm cov khoom siv yuav tsum zoo ib yam thiab zoo ib yam, tsis muaj kev puas tsuaj rau cov khoom siv, thiab yuav tsum tsis txhob muaj qhov oxidation ntawm cov pob qij txha thiab cov hlua sib txuas; Txhua lub roj teeb thiab kev sib txuas ntawm cov khoom siv sib txuas yuav tsum tau teem caij kom zoo, thiab cov thav duab ntawm cov khoom yuav tsum huv si thiab tsis muaj corrosion; Cov npuas lossis delamination tsis raug tso cai los tsim txoj hauv kev ntawm lub roj teeb thiab cov ntug ntawm cov khoom hauv cov txheej ntim ntawm cov khoom. Qhov ntev geometric thiab tus naj npawb ntawm npuas los yog delamination yuav tsum ua raws li cov lus qhia ntxaws txog cov khoom lag luam.
3. Lub zog rau thaj tsam ntawm qhov sib piv yog ntau dua 65W / ㎡, lub zog rau qhov hnyav piv yog ntau dua 4.5W / kg, thiab cov khoom ntim FF yog ntau dua 0.65; Lub rwb thaiv tsev tsis kam ntawm cov khoom siv nyob rau hauv ib txwm muaj kev tiv thaiv yuav tsum tsis pub tsawg dua 200M Ω;
Lub zog cheeb tsam piv:qhia txog tus nqi hluav taws xob uas ib cheeb tsam ntawm photovoltaic module tuaj yeem tsim tau. Lub zog ntau dua rau thaj tsam piv txhais tau tias muaj hluav taws xob ntau dua tuaj yeem tsim tawm ntawm tib cheeb tsam.
Lub zog rau qhov hnyav piv:ntsuas tus nqi hluav taws xob tsim los ntawm ib chav tsev hnyav ntawm photovoltaic modules. Lub zog ntau dua rau qhov hnyav piv qhia tau tias cov khoom siv hluav taws xob photovoltaic tuaj yeem tsim hluav taws xob ntau dua nyob rau hauv tib qhov hnyav, uas yog qhov tseem ceeb tshwj xeeb rau kev tsim lub teeb yuag thiab siv tau yooj yim.
Fill factor (FF):Nws yog ib qho tseem ceeb parameter rau kev ntsuam xyuas kev ua tau zoo ntawm photovoltaic modules, uas sawv cev rau qhov piv ntawm lub siab tshaj plaws lub hwj chim ntawm lub photovoltaic module rau cov khoom ntawm lub qhib Circuit Court voltage thiab luv-circuit tam sim no. Qhov siab dua qhov ua tau zoo, qhov ze dua cov yam ntxwv ntawm cov khoom siv hluav taws xob photovoltaic yog mus rau ib lub duab plaub, qhia txog kev ua haujlwm ntawm photoelectric ntau dua. Kev ua kom zoo dua tuaj yeem ua kom ntseeg tau tias cov khoom siv hluav taws xob photovoltaic tswj tau lub zog hloov pauv kev ua tau zoo nyob rau hauv ntau yam ib puag ncig.
4. Qee qhov kev ua haujlwm tseem ceeb ntawm cov khoom siv: sau qhov FF ntawm 0.5 thiab 0.8; Lub ncov voltage ntawm cov tivthaiv nrog 36 roj teeb hlwb txuas nrog hauv series yog 17 ~ 17.5V; Qhov qhib hluav taws xob hluav taws xob ntawm cov khoom siv nrog 36 lub roj teeb txuas nrog hauv cov koob yog nyob ib puag ncig 21V.
5. Qhov sib txuas ntawm cov khoom sib txuas EVA yuav tsum siab dua 65%, thiab lub zog tev ntawm EVA thiab iav yuav tsum siab dua 30N / cm3, Lub zog tev ntawm EVA thiab cov khoom siv rov qab yog ntau dua 40N / cm; Thiab muaj cov kev ntsuas txhim khu kev qha rau kev tiv thaiv daus, tiv thaiv condensation, tiv thaiv overheating, tiv thaiv plua plav, tiv thaiv xob laim, lawg tiv thaiv, typhoon tsis kam, thiab av qeeg.
6. Txhua qhov photovoltaic module yuav tsum muaj daim ntawv lo: cov khoom npe thiab qauv; Cov kev ua haujlwm tseem ceeb: suav nrog luv-circuit tam sim no Isc, qhib Circuit Court voltage Voc, ncov kev khiav hauj lwm tam sim no Im, ncov kev khiav hauj lwm voltage Vm, ncov hwj chim Pm, IV nkhaus, tivthaiv hnyav, kuaj tej yam kev mob, siv ceev faj, thiab lwm yam; Thiab cov chaw tsim khoom lub npe, hnub tsim khoom, thiab cov cim lag luam, thiab lwm yam.
