Izindlela Ezinhle Kakhulu Zokuqeda Ukuhluleka Kwesixhumi Se-Solar PV

     Izixhumi ze-Solar PVidlala indima ebalulekile ekuhlanganisweni kwezintambo zelanga.Njengoba iklanywe, ihlinzeka ngogesi ophezulu, wamanje ophezulu, uxhumo lwe-DC olungamelana kancane uma lufakwe kahle, futhi izindlu zazo azikwazi ukungena emanzini, zimelana nezinga lokushisa, zimelana ne-UV, futhi zinesikhathi sokuphila esifika eminyakeni engu-25 noma ngaphezulu.Ngaphezu kwalokho, ubuchwepheshe babo bokuxhumanisa busheshisa ukufakwa kwama-solar arrays.Kodwa-ke, izixhumi ze-PV zivame ukuba ngumthombo wokuhluleka kwe-solar array.

Ucwaningo olwenziwa yi-Fraunhofer Institute for Solar Energy Systems ISE yaseFreiburg, eJalimane, luhlole izimbangela zokuhluleka kwezinga lokushisa kwe-PV arrays futhi lwathola ukuthi izixhumi ze-solar PV nama-crimp kwakuyimbangela eyodwa enkulu kunazo zonke yokuhluleka kwezintambo ze-DC.Iningi lalokhu kwehluleka kwenzeke phakathi neminyaka emihlanu yokuqala yokufakwa, okuholele abacwaningi ukuba basole imikhuba emibi yokufaka njengembangela eyinhloko.

Izingxoxo lapha e-United States nabahloli bakagesi nazo ziveze imininingwane elandelayo ekuhlulekeni kwesixhumi se-PV:

Abahloli abaningana baphinde babona izifaki zensimu zibopha izixhumi ze-PV ngodlawu.Amazwana engeziwe agqamise ukulingana "okuxekethile" kwezixhumi ze-PV zabakhiqizi abahlukene.

Okuhlanganisa ukuhluleka kwe-array yezixhumi ze-solar PV ukuthi kungase kube nzima ukubona ukuhlangana okungalungile kanye nama-crimp angalungile okuxhumana.Ukwehluleka koxhumano kuvame ukufihlwa kuzixhumi ezibonakala zenza ukuthintana okuhle.Ngaphandle uma isixhumi sinephutha ngokuphelele, njengesixhumi esikhubazekile noma esincibilikisiwe, cishe akunakwenzeka ukusibona ngeso lenyama.Ukuthwebula izithombe ezishisayo kuvame ukuba ukuphela kwendlela yokuthola lezi zinkinga.Ukulahlekelwa kwamandla, ukuxilongwa kanye nezindleko zokulungisa ezihlobene nalokhu kwehluleka okufihliwe kungaba phezulu.

Ukwehluleka kwesixhumi se-Solar PV kungahlukaniswa ngezigaba ezimbili: izinkinga zokungahambisani nezinkinga zezintambo zesixhumi.Izixhumi ezifakwe efekthri ngemuva kwamamojula e-PV ngokuvamile aziwona umthombo oyinhloko wezinkinga, futhi okuningi kwalokhu kwehluleka kuhlobene nezintambo zenkambu.Kodwa-ke, izixhumi ezifakwe ensimini ezifana nalezo zentambo yokugcina izintambo ezisetshenziswa ngentambo nezinye iziguquli ezimaphakathi zingaba yinkinga.

Izinkinga zokungahambisani ngokuvamile zibangelwa ukuhlangana kwezixhumi ze-photovoltaic ezivela kubakhiqizi abahlukene.Nakuba izixhumi eziningi zibhekwa “njengezihambisanayo,” alikho izinga lemboni ledizayini yesixhumi esifanayo.Ngenxa yomehluko ekubekezeleni kokuklama, izidingo zethuluzi le-crimp kanye nezinto zokuthintana nezindlu, uxhumano lukagesi olulungile alukwazi ukuqinisekiswa.Ngaphezu kwalokho, ngenkathi zonke izixhumi ze-PV kufanele zihlolwe ku-UL 6703, leli zinga alibandakanyi ukuhlangana kwezixhumi ezivela kubakhiqizi abahlukene ngaphandle kokuthi kuhlolwe ngokuqondile - into engavamile ukwenziwa.Abanye abakhiqizi baxwayisa ngokukhwelana kwezinhlobo ezahlukene zezixhumi, futhi izinqubo ezinconyiwe kufanele zilandelwe.

Izixhumi eziningi ze-solar PV zisebenzisa oxhumana nabo besitayela se-crimp.Kungakhathaliseki ukuthi kufakwe efekthri noma inkambu, lezi zixhumi zidinga ithuluzi le-crimp elinconywe ngumkhiqizi kanye nokuhlanganisa okufanele ukuze kufakwe okungenazinkinga.Izidingo zokulinganisa ithuluzi le-crimp kanye nemikhawulo ye-crimp die kufanele kulandelwe ukuze kufakwe okungenazinkinga phakathi nesikhathi sokuphila sohlelo lwelanga.Izixhumi ezintsha ze-PV ezingenamathuluzi manje seziyatholakala futhi.Lezi zixhumi ziqeda imfuneko yamathuluzi nokuhlanganisa, zisebenzisa intwasahlobo ethintwayo ekwazi ukumelana nezinga lokushisa nokudlidliza ukuze kuxhunywe izintambo.

Isixazululo sezinselele zokuhluleka kwesixhumi se-photovoltaic ukuqinisekisa ukufakwa okulungile ngesikhathi sezintambo zokuqala ze-PV.Ezinye izinqubo ezingcono kakhulu ezingasetshenziswa ukufeza lokhu yilezi:

Ngaphezu kwezinselele zokuhlangana okufanele kwezixhumi ze-solar PV, kunenkinga yokuhlangana kwe-PV yesixhumi esingahambelani.Izinqubo ezihamba phambili kule ndawo zihlanganisa njalo ukucacisa uhlobo olufanayo lwesixhumi senkambu njengalolo olunikezwe umkhiqizi wemojula ye-PV.Lokhu kufaka phakathi ukusetshenziswa kwama-microinverters nama-optimizers.Abanye balaba bakhiqizi benza lokhu kube lula kwezinye izimo ngokunikeza ukukhetha kwemikhiqizo yesixhumi se-PV kumishini yabo.

Ukusetshenziswa kwezixhumi ze-PV ezivela kumkhiqizi ofanayo, ukuqeqeshwa okufanele, amathuluzi e-crimp anconyiwe noma ukusetshenziswa kwezixhumi ze-PV zokuxhumana zasentwasahlobo ezingenamathuluzi kungasiza ukunciphisa umthelela wokuhluleka kwesixhumi.
