Njengoba ukubamba kweqhwa ebusika kuqala, ukukhathazeka ngokusebenza kobuchwepheshe obusebenzisa amandla elanga, ikakhulukazi izibani zasemgwaqweni zelanga, kuya phambili. Izibani zelanga ziphakathi kwemithombo yamandla ehlukile ethandwa kakhulu yokukhanyisa izingadi nemigwaqo. Ingabe lezi zibani ezinobungani nemvelo nezisebenzisa amandla kahle ziyamelana nezinselele ezibangelwa amazinga okushisa abandayo nezinsuku ezimfushane? Kulesi sihloko, sichaza isayensi ngemuva kwezibani zasemgwaqweni zelanga futhi sihlole ukuthi lezi zibani zivela kanjaniI-E-litehhayi nje kuphela ukukhuthazela kodwa nokuqhubeka nokukhanyisa imigwaqo yethu ebusika.
Ukuvuna Ukukhanya Kwelanga, Ngisho Nasebusika
Enye yezinto ezikhathazayo kakhulu ebusika amahora okukhanya kwelanga anciphile. Uma izibani zasemgwaqweni zelanga zisebenza ebusika, zingase zingasebenzi kahle kule sizini ngenxa yezici eziningana ezifana neqhwa elimboza amaphaneli, i-engeli yokwanda kwelanga, ukwehla kwemisebe yelanga, nezinye izici. Kodwa-ke, izibani zasemgwaqweni zelanga zeI-E-litezihlonyiswe ngamaphaneli elanga e-silicon e-mono-crystalline asezingeni eliphezulu angakwazi ukusebenzisa ukukhanya kwelanga ngempumelelo, ngisho nasezimweni eziguqubele. Umklamo wanamuhla wala maphaneli uqinisekisa ukuguqulwa okuqhubekayo kokukhanya kwelanga kube amandla kagesi, okunikeza ukunikezwa kwamandla okuqhubekayo kwezibani.
Isitoreji Sebhethri Sobusuku Obude
Njengoba ubusuku basebusika buqhubeka bukhula, izibani zasemgwaqweni zelanga zithembele kumabhethri ashajwayo ukuze zigcine amandla angaphezulu akhiqizwa emini. Amabhethri e-lithium asezingeni eliphezuluI-E-litezisetshenziselwa ukugcina amandla, ukunikeza amandla ezidingweni ezisheshayo, nokuvumela ukusekelwa kwezinsuku lapho ilanga lincane noma lingekho khona. Ukusebenza kahle okuphezulu kokukhanya okungu-185 ~ 200lm/W ukuze kukhuliswe ukusebenza kwebhethri. Futhi ikhwalithi yebhethri lethu ingalawulwa ngokuqinile ngoba sinomugqa wokukhiqiza ozimele futhi singaqinisekisa ukuthi amabhethri wonke avela kowokuqala kodwa awaphinde asetshenziswe. Lawa mabhethri aklanyelwe ukumelana namazinga okushisa abandayo, okuqinisekisa ukunikezwa kwamandla okuqhubekayo phakathi namahora asebusuku ande. Lo mthamo wokugcina uba obalulekile ekulondolozeni ukukhanya phakathi nobumnyama obude basebusika.
Ukukhuthazela Kwasebusika Kobuchwepheshe be-LED
Inhliziyo yezibani zasemgwaqweni zelanga itholakala kuma-Light Emitting Diodes (ama-LED), aziwa ngokuqina kwawo nokusebenza kahle. Ngokungafani nobuchwepheshe bokukhanyisa bendabuko obungase bube nzima emakhazeni, ama-LED asebenza kahle ngisho nasemazingeni okushisa abandayo. Lokhu kuwenza abe ukukhetha okuthembekile kokugcina ukukhanya okufanayo phakathi nobusuku basebusika.I-E-liteine-LED ene-lumen ephezulu ukuze isebenze kahle kakhulu kanye nobuchwepheshe obukhethekile bokulawula ilanga obuklanywe nge-low voltage obunekhono lokufiphaza lokuphatha ukonga amandla.
Ubuchwepheshe Obuhlakaniphile Bokusebenza Kahle
Izibani zasemgwaqweni zelanga zivame ukufaka izici ezihlakaniphile njengezinzwa zokunyakaza kanye nokulawula ukukhanya okuguqukayo. Lezi zobuchwepheshe zinegalelo elikhulu ekongiweni kwamandla ebusika. Izinzwa zokunyakaza ziqinisekisa ukuthi izibani zisebenza kuphela uma kudingeka, kuyilapho ukukhanya okuguqukayo kuzivumela ukuthi zilungise ukuqina kwazo ngokusekelwe ezidingweni zesikhathi sangempela, zithuthukise ukusetshenziswa kwamandla ezinyangeni ezibandayo nezimnyama. Kwenzeka kanjalo nje, kunezinhlobo ezintathu zezilawuli kuI-E-liteukufeza le misebenzi.
1. Isilawuli se-MPPT Self Proprietary
Inezindlela ezintathu okuyimodi engaguquki, imodi yokusuka emini kuya kokusa kanye nemodi yesensa yokunyakaza. Ukukhanya kuzovula ngokuzenzakalelayo lapho kuphuma ilanga futhi kugcine ukukhanya okungaguquki okungu-45% emandleni asethiwe esikhathini esingaphansi kwemodi engaguquki. Futhi kuzovula lapho kuphuma ilanga futhi kuhlale kukukhanya okungafika ku-100% amahora ama-4, bese kuphenduka kukukhanya okungafika ku-30% kuze kube yilapho kuphuma ilanga ngaphansi kwemodi yokusuka emini kuya kokusa. Ngaphezu kwalokho, isilawuli sizosebenza ngokuzenzakalelayo kukukhanya okungafika ku-30% ngaphansi kwemodi yesensa yokunyakaza. Uma kutholwa ukunyakaza, ukukhanya kuyanda kufinyelele ku-100% kuze kube yilapho kungatholakali ukunyakaza imizuzwana engama-30, bese kubuyela ekukhanyeni okungafika ku-30%.
2. Isilawuli se-MPPT esijwayelekile
Lesi silawuli sinemodi emibili, imodi yezigaba ezinhlanu kanye nemodi yenzwa yokunyakaza. Uma usebenzisa imodi yokuqala, izibani zihlukaniswa zibe yizigaba ezi-5, isikhathi ngasinye sesigaba kanye nokukhanya kungabekwa ngokwezidingo. Ngokusethwa kokukhanya, kuyindlela ephumelelayo yokonga amandla, nokugcina isibani sisebenza ngamandla nangesikhathi esifanele. Futhi lapho ukukhanya kuphendukela kwenye imodi, kungaveza ukukhanya okuhlukile ngezikhathi ezahlukene ngokunyakaza nangaphandle kokunyakaza.
3. Isilawuli se-Hybrid MPPT
Izindlela ezintathu ongazikhethela zona, kusukela ekuphumeni kwelanga kuya ekuntweleni (D2D), imodi yasebusuku enezigaba ezinhlanu kanye nemodi ye-TOT (ungasetha umthwalo ngesikhathi ngaphambi kokuba kuse.)
Ekuphetheni, izibani zasemgwaqweni zelanga aziphazanyiswa ukubanda kwasebusika. Ngokuhlanganisa ubuchwepheshe obuthuthukisiwe bephaneli yelanga, isitoreji sebhethri esisebenzayo, izibani ze-LED ezihlala isikhathi eside, kanye nezici ezihlakaniphile, lezi zibani ziyaqhubeka nokukhanya kahle phakathi nezinyanga ezibandayo kakhulu. Njengoba ubusika buqala, izibani zasemgwaqweni zelanga ziyibufakazi bokuthembeka nokusebenza kahle kwezixazululo zokukhanyisa eziqhubekayo, ezihlinzeka hhayi nje kuphela ngokukhanya kodwa futhi nokukhanya kokuqaphela imvelo lapho kubhekene nezinkathi ezishintshayo.I-E-liteungumngane ongamethemba ngokuphelele ngoba singakunikeza izixazululo zokukhanyisa ezinhle kakhulu emazingeni okushisa aphansi.
