1. Lub xov tooj ntawm tes photovoltaic yog qhov muaj peev xwm tiv taus tam sim no, thiab lub roj teeb yog qhov tsis muaj hluav taws xob tsawg. Qhov no qhia ncaj qha tias peb tuaj yeem ua cov khoom siv luv luv, tab sis tsis txhob luv luv-circuit batteries.
2. Thaum lub roj teeb npog, nws dhau los ua lub hom phiaj loj ua haujlwm. Yog hais tias nws tsis tau drained, nws yuav sai sai cua sov. Qhov no kuj yog lub hauv paus ntsiab lus ntawm kev tivthaiv thiab bypass diode activated switching.
3. Qhov sib txawv ntawm STC (tus qauv kuaj mob, uas yog, tus qauv kuaj mob) thiab NOCT (Nomina lOperating Cell Temperature, hnub ci cell nominal ua hauj lwm kub), ntxiv rau cov zauv sib txawv nyob rau hauv ob peb tsim tsis, NOCT qhia ib tug cua ceev ntawm 1m / s Lub hom phiaj ntawm qhov ntsuas yog ua kom zoo dua qhov tso zis hluav taws xob ntawm cov khoom siv thaum lub sijhawm ua haujlwm.
4. Lub 25 degrees Celsius txhais los ntawm STC tus qauv lub xeev ntawm cov tivthaiv yog cov kev khiav hauj lwm kub ntawm lub tivthaiv es tsis yog lub ambient kub. Yog li thaum koj xam cov nyhuv ntawm qhov kub thiab txias ntawm qhov tsawg kawg nkaus kev khiav hauj lwm voltage, koj yuav tsum tau ntxiv ib qho ntxiv 25 degrees rau qhov kub ntawm lub roj teeb vaj huam sib luag ntawm chav tsev kub. Txawm li cas los xij, thaum xam qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov siab tshaj plaws qhib qhov hluav taws xob, nws tsis tuaj yeem ntxiv qhov kub thiab txias ua haujlwm ntawm 25 degrees. Qhov no 25 degrees, rau kev xam cov haujlwm saum toj no 3kW, yog qhov yuam kev loj heev.
5. Nco ntsoov tias cov khoom ntawm tib qhov loj thiab cov khoom siv tib yam (ib leeg siv lead ua / polycrystalline) nrog tib lub zog ntsuas, yog tias qhov kev hloov pauv tsis zoo ib yam, nws yog kev dag ntxias. Qhov no kuj yog ib txoj cai, tsis muaj kev zam.
6. Lub zog ua haujlwm ntawm cov khoom siv hluav taws xob siab tshaj plaws thiab cov khoom siv hluav taws xob qhib qhov hluav taws xob muaj kev sib raug zoo ntawm 0.8, uas yog ze heev. Qhov kev sib raug zoo no yog qhov tseem ceeb heev thiab yooj yim thaum pib kwv yees qhov kev sib haum xeeb ntawm lub inverter thiab cov qauv tsim. Nyob rau tib lub sijhawm, nws tseem ceeb heev rau kev tsim qauv ntawm MPPT.
7. Nyob rau hnub huab cua los yog drizzly yam tsis muaj lub hnub, lub zog tso zis ntawm lub kaw lus me me heev. Qhov tseeb, qhov qhib Circuit Court voltage lossis ua haujlwm voltage ntawm Amerisolar Cheebtsam tseem yog siab heev, txawm tias tag nrho cov load! Ntau tus neeg tsim khoom hauv tebchaws Australia uas tau hloov cov tshuab hluav taws xob hauv tsev nyob rau hnub huab cua tau hluav taws xob. Nco ntsoov tias nyob rau hnub huab cua, cov khoom tiv thaiv yuav tsis tso zis hluav taws xob, tab sis nws tsis txhais hais tias nws tuag. Qhov no yog ib qho kev nkag siab zoo uas feem ntau tsis saib xyuas.
8. Yog hais tias tus naj npawb ntawm cov Cheebtsam nyob rau hauv lub sab hnub tuaj-sab hnub poob txoj kev yog tib yam, nws yuav tsum tau kev cob cog rua nyob rau hauv parallel, thiab tsis muaj ib tug loj voltage dislocation. Yeej, ntev npaum li qhov siv lub teeb siab dua 50W / m2, cov khoom siv tuaj yeem ua haujlwm thiab tso zis hluav taws xob. Qhov no piav qhia txog qhov tshwm sim uas lub inverter pib ntxov, tab sis lub zog tso tawm tiag tiag poob qab rau lub sijhawm.
