Inqubo Yokukhiqiza Izintambo Zezinhlelo Zamandla Elanga
Izinhlelo ze-solar PV zisetshenziswa kakhulu ngoba zingahlinzeka ngogesi ohlanzekile, wesikhathi eside, noguquguqukayo ezikalini ezahlukene—kusukela emakhaya okuhlala kuya ezitshalweni zamandla ezinkulu. Kodwa-ke, ukusebenza nokuphepha kohlelo lwe-solar PV akunqunywa kuphela ngamaphaneli, ama-inverter, namabhethri, kodwa futhi nangengxenye evame ukuthathwa kalula: izintambo. Izintambo ekufakweni kwe-PV kumele zikwazi ukudlulisa kokubili ugesi oqondile (DC) kanye nogesi oshintshanayo (AC), zimelane nokushisa kanye nemisebe ye-UV, futhi zibe nokushisa okuqinile ukuvimbela ukuvuza kwamanje kanye nengozi yomlilo. Ngakho-ke, inqubo yokukhiqiza izintambo zezinhlelo ze-solar PV inezindinganiso zobuchwepheshe eziqinile kunezintambo zikagesi ezivamile. Lesi sihloko sixoxa ngezigaba zokukhiqizwa kwekhebula le-solar PV, kusukela ekukhethweni kwezinto kuya ekuhlolweni kwekhwalithi.
1. Indima Yamakhebula Ezinhlelweni Zamandla Elanga
Ohlelweni lwe-PV, izintambo zixhuma izingxenye eziningana ezibalulekile: kusukela kumamojula elanga kuya ebhokisini lokuhlanganisa, kusukela ebhokisini lokuhlanganisa kuya ku-inverter, kusukela ku-inverter kuya kuphaneli yokusabalalisa ye-AC, futhi ekugcineni kuya kugridi yomthwalo noma yamandla. Ngaphezu kwalokho, ezinhlelweni ze-hybrid, izintambo zixhuma nebhethri kanye nesilawuli sokushaja. Izintambo ezisetshenziswayo kumele zikwazi ukumelana nama-voltage aphezulu (ngokuvamile angu-600–1500 V DC ezinhlelweni zesimanje), zisebenze ngokuqina ebangeni elibanzi lokushisa, futhi zimelane nezimo zezulu ezimbi kakhulu lapho zifakwa ngaphandle. Yingakho izintambo ze-PV—ngokuvamile ezaziwa ngokuthi izintambo zelanga—ngokuvamile zisebenzisa ukufakelwa okukhethekile kanye nama-conductor asezingeni eliphezulu.
2. Ukukhethwa Kwezinto Zokuqhuba
Isigaba sokuqala ekukhiqizweni kwekhebula ukukhetha izinto zomqhubi, ingxenye eyinhloko eqhuba ugesi. Izinto ezimbili ezivame kakhulu ithusi ne-aluminium. Ithusi livame ukusetshenziselwa izinhlelo zamandla elanga ngenxa yokuqhuba kwalo okuphezulu, ukumelana nokugqwala, kanye namandla amahle omshini. Ithusi liphinde lizinze kakhulu ekuxhumeni, ikakhulukazi ezixhumini ze-MC4 nezinye iziphetho ezidinga ukuthintana okuqinile nokumelana nokushisa.
Ithusi elisetshenziswayo ngokuvamile lihlanzekile kakhulu (isibonelo, 99,9%) ukuze kuncishiswe ukulahleka kwamandla. Ngaphezu kohlobo lwezinto ezibonakalayo, abakhiqizi banquma nesimo sekhondisi: singaba siqinile noma sibambeke. Izintambo zelanga ngokuvamile zisebenzisa amakhondisi anezintambo ezincane ngoba aguquguquka kalula, kulula ukuwafaka, futhi amelana kakhulu nokudlidliza nokugoba okuphindaphindiwe.
3. Inqubo Yokudweba Ngezintambo
Uma izinto zomqhubi sezikhethiwe, ithusi livame ukuba sesimweni senduku enobubanzi obukhulu. Le nduku ibe isicutshungulwa ngomshini wokudweba ucingo ukuze idonswe entanjeni enobubanzi obuncane obudingekayo. Kule nqubo, induku idluliswa ochungechungeni lwezinto ezidayisayo ezinciphisa kancane kancane ububanzi. Inqubo yokudweba yenziwa ngaphansi kokulawulwa okuqinile ukuqinisekisa ukuthi indawo yentambo ibushelelezi, ububanzi obuhambisanayo, kanye nokungabikho kwamaphutha njengemifantu emincane.
Kwamanye amafektri, ngemva kokudweba, ucingo luyafakwa futhi (ukushisa okulawulwayo) ukuze kubuyiselwe ukuguquguquka kwezinto. Ukufakwa kwentambo kubalulekile ukuvimbela ucingo ukuthi lungabi luqinile kakhulu futhi luqhekeke, okwenza lufanelekele ukusetshenziswa njengomqhubi oguquguqukayo ogoqekile.

Iphethini yokujika kanye nenani lezintambo kunqunywa ukuqinisekisa ukuthi umqhubi ulinganisela ukuguquguquka kanye namandla omshini.
Ezinhlelweni zamandla elanga, ukuguquguquka kuyinto enhle ngoba izintambo zivame ukufakwa ophahleni, ngemigudu, noma ezindleleni ezigobile. Izintambo eziqinile kakhulu zenza kube nzima ukufakwa futhi zandisa ingozi yokulimala kokufakwa kokushisa okuvela ekugobeni okubukhali.
5. Ukufakwa Kwezinto Zokuvala Ukushisa Nezigqoko
Isinyathelo esilandelayo ukuvikela ukushisa. Kumakhebula kagesi elanga, ukuvikela ukushisa ngokuvamile kusebenzisa izinto ezikhethekile ze-polymer ezifana ne-XLPE (Cross-Linked Polyethylene) noma ama-compounds angenawo amalangabi e-halogen. Lezi zinto zikhethwa ngoba zingamelana namazinga okushisa aphezulu okusebenza (ngokuvamile afinyelela ku-90°C, ngisho no-120°C ezimweni ezithile), azimelani ne-UV, azimelani ne-ozone, futhi azimelani nomswakama.
Inqubo yokufaka ukufakelwa kokushisa yenziwa kusetshenziswa indlela yokukhipha. Umqhubi ufakwa ku-extruder, lapho izinto zokufakelwa kokushisa ezifudumele zincibilikiswa khona futhi zimbozwe ngokulinganayo nxazonke zomqhubi. Ubukhulu bokufakelwa kokushisa bulawulwa ngokuqinile ngoba buthinta amandla ayo okuthwala i-voltage kanye nokuphepha. Ngemva kokuphuma ku-extruder, ikhebula liyapholiswa kancane kancane kusetshenziswa amanzi noma umoya ukuqinisekisa ukuthi ukufakelwa kokushisa kuyaqina ngokuphelele ngaphandle kokuqhekeka.
Kumakhebula elanga, umklamo ofakwe kabili (izendlalelo ezimbili zokufakwa kokushisa) noma inhlanganisela yokufakwa kokushisa kanye nejakethi yangaphandle eqinile ngokulinganayo kuvame ukusetshenziswa. Ijakethi yangaphandle isebenza njengesivikelo ekungqubuzaneni, isimo sezulu, uwoyela othile, kanye nokuvezwa kwemvelo.
6. Ukufaka Umbala, Ukumaka, kanye Nokuhlonza
Izintambo ze-PV zivame ukutholakala ngombala omnyama nobomvu (we-DC), kanti izintambo zokumisa zingaba luhlaza okwesibhakabhaka nophuzi. Umbala wenziwa ngesikhathi senqubo yokukhipha ngokufaka imibala engamelana ne-UV ukuvimbela ukufiphala. Ngaphezu kombala, izintambo ziphawulwa ngombhalo ezindaweni zazo, okuhlanganisa usayizi wekhebula, amazinga ahlangatsheziwe, i-voltage yokusebenza, igama lomkhiqizi, unyaka wokukhiqiza, kanye nezimpawu zamamitha (izimpawu zobude ngemitha). Lokhu kumaka kuyasiza ngesikhathi sokufakwa nokuhlolwa, futhi kusiza ukuqinisekisa ukuthi ikhebula lihlangabezana nezimpawu ze-PV.
7. Ukulawulwa Kwekhwalithi
