Ingaba ukusebenza kwephaneli yelanga kunokwandiswa njani ziiseli zelanga ezisikwe ngesiqingatha?

1.Nciphisa ilahleko yokuxhathisa

Xa iiseli zelanga ziguqula ukukhanya kwelanga zibe ngumbane, ukulahlekelwa kwamandla ikakhulu kuvela ekulahlekelweni kokuchasana okanye ukulahlekelwa kwinkqubo yokuhanjiswa kwangoku.

Iiseli zeSolar zisasaza umsinga ngeebhanti zentsimbi ezicekethekileyo kumphezulu wazo kwaye zizidibanise neengcingo ezikufutshane kunye neebhetri, nto leyo ebangela ukulahleka kwamandla xa umsinga udlula kula mabhanti esinyithi.

Iphepha leseli yelanga linqunywe kwisiqingatha, ngaloo ndlela linciphisa isiqingatha samanje esiveliswa yiseli nganye, kwaye njengoko ikhoyo ngoku ihamba ngeeseli kunye neengcingo kwipaneli yelanga, ukuhamba okuphantsi kwangoku kukhokelela ekulahlekeni okuphantsi kokumelana. Ngaloo ndlela, ukulahlekelwa kwamandla kwecandelo kuncitshisiwe kwaye umsebenzi walo ungcono.

2.Ukunyamezela kwe-shading ephezulu

Iseli enqunyulwe ngesiqingatha ayichatshazelwa kangako kukuvala isithunzi kuneseli yonke. Oku akubangelwa ukuba ibhetri inqunywe kwisiqingatha, kodwa ngenxa yeendlela ezahlukeneyo zocingo ezisetyenziselwa ukudibanisa ibhetri yesiqingatha-esikiwe kwindibano.

Kwiiphaneli ye-photovoltaickwiphepha lebhetri elipheleleyo, ibhetri idibaniswe kunye ngendlela yemigca, ebizwa ngokuba yi-wireing series. Kuluhlu lwe-wiring scheme, ukuba iseli ifihliwe kwaye ayivelisi amandla, umqolo wonke weeseli kwichungechunge uya kuyeka ukuvelisa amandla.

Umzekelo, eqhelekileyoimodyuli yelangaineentambo zebhetri ezi-3, nganye ine-bypass diode. Ukuba enye yeentambo zebhetri ayivelisi amandla ngenxa yokuba enye yeeseli ivaliwe, ngoko kuyo yonke icandelo, oko kukuthi, i-1/3 yeeseli ziyeka ukusebenza.

Kwelinye icala, iiseli ezisikwe ngesiqingatha zikwadityanisiwe kuthotho, kodwa ekubeni amacandelo enziwe ngeeseli ezisikwe ngesiqingatha zinenani eliphindwe kabini leeseli (i-120 endaweni ye-60), inani lemiqolo nganye liphinda kabini.

Olu hlobo lwe-wiring luvumela amacandelo aneeseli ezisikwe ngesiqingatha ukuba alahlekelwe amandla amancinci xa iseli enye ivaliwe, ekubeni iseli enye evaliweyo inokuphelisa isinye kwisithandathu sokukhutshwa kwamandla kwecandelo.

Isizathu kukuba i-half-cutimodyuli yelangaineentambo zebhetri ezi-6 (kodwa kuphela ii-bypass diode ezi-3), ibonelela ngonyamezelo olungcono lwesithunzi sendawo. Ukuba isiqingatha secandelo sifihliwe sisithunzi, esinye isiqingatha sinokuqhubeka nokusebenza.

3.Nciphisa umonakalo weendawo zokushisa kumacandelo

Xa iseli enye yelanga kumtya webhetri yemodyuli ikhuselwe, zonke iiseli ezidlulileyo ezingakhuselekanga zingagalela amandla azivelayo kwiseli ekhuselekileyo njengobushushu, obumba indawo yokushisa enokubangela umonakalo kwimodyuli yelanga ukuba ihlala ixesha elide.

Kumacandelo aneeseli ezisikwe ngesiqingatha, umtya ophindwe kabini weeseli wabelana ngobushushu obugalelwe kwiseli evaliweyo, ngoko ke umonakalo kwimodyuli ukusuka ekugaleleni ubushushu obuncinci nawo uyancitshiswa, nto leyo enokuphuculaiphaneli yelangaumonakalo owenziwe ngamabala obushushu.
