Ukusebenza kwephaneli yelanga kungathuthukiswa kanjani ngamaseli elanga asikwe uhhafu?

1.Yehlisa ukulahlekelwa ukumelana

Lapho amaseli elanga eguqula ukukhanya kwelanga kube ugesi, ukulahlekelwa kwamandla ikakhulukazi kuvela ekulahlekelweni kokumelana noma ukulahlekelwa yinqubo yamanje yokudlulisela.

Amaseli elanga adlulisa amandla ngamabhande ensimbi azacile ezindaweni zawo futhi awaxhume ezintanjeni eziseduze namabhethri, okubangela ukulahleka kwamandla lapho i-current idlula kulawa mabhande ensimbi.

Ishidi le-solar cell linqunywa ngesigamu, ngaleyo ndlela lihlukanise isigamu samanje esikhiqizwa iseli ngalinye, futhi njengoba okwamanje igeleza ngamaseli nezintambo kuphaneli yelanga, ukugeleza kwamanje okuphansi kuholela ekulahlekelweni okuphansi kokumelana. Ngakho, ukulahlekelwa kwamandla kwengxenye kuncishisiwe futhi umsebenzi wayo ungcono.

2.Ukubekezela okuphezulu kwe-shading

Iseli elisikwe uhhafu alithinteki kakhulu ukuvaleka kwethunzi kunalo lonke iseli. Lokhu akubangelwa ukunqanyulwa kwebhethri phakathi, kodwa ngenxa yezindlela ezihlukene zokufaka izintambo ezisetshenziswa ukuxhuma ibhethri elisike uhhafu emhlanganweni.

KweIphaneli ye-photovoltaic eshidini lebhethri eliwusayizi ogcwele, ibhethri ixhunywe ndawonye ngendlela yemigqa, ebizwa ngokuthi i-series wiring. Kuhlelo lochungechunge lwezintambo, uma iseli lisithekile futhi lingawakhiqizi amandla, wonke umugqa wamaseli ochungechungeni uzoyeka ukukhiqiza amandla.

Ngokwesibonelo, evamilemodule solar inezintambo zebhethri ezi-3, ngayinye ine-bypass diode. Uma enye yezintambo zebhethri ingakhiqizi amandla ngoba elinye lamaseli livinjiwe, khona-ke kuyo yonke ingxenye, okungukuthi, i-1/3 yamaseli iyeka ukusebenza.

Ngakolunye uhlangothi, amangqamuzana anqunywe ngesigamu nawo axhunywe ochungechungeni, kodwa njengoba izingxenye ezenziwe ngamaseli anqunywe uhhafu zinenani lamaseli kabili (120 esikhundleni sika-60), inani lemigqa ngayinye liphinde kabili.

Lolu hlobo lwezintambo luvumela izingxenye ezinamaseli asikwe uhhafu ukuthi zilahlekelwe amandla amancane lapho iseli elilodwa livinjiwe, njengoba iseli elilodwa elivinjiwe lingasusa kuphela ingxenye eyodwa kwesithupha yokukhishwa kwamandla kwengxenye.

Isizathu kungenxa yokuthi i-half-cutmodule solar inezintambo zebhethri eziyisi-6 ezihlukene (kodwa kuphela ama-bypass diode ama-3), enikeza ukubekezelela okungcono kwethunzi lendawo. Uma ingxenye yengxenye isithwe isithunzi, enye ingxenye isengaqhubeka nokusebenza.

3.Yehlisa umonakalo wezindawo zokushisa ezingxenyeni

Lapho iseli elilodwa lelanga entanjeni yebhethri yemojula livikelwe, wonke amaseli angavinjiwe angathululela amandla awakhiqizayo esitokisini esivikelwe njengokushisa, okwenza indawo yokushisa engabangela umonakalo kumoduli yelanga uma ihlala isikhathi eside. .

Ezingxenyeni ezinamaseli asikwe uhhafu, intambo ephindwe kabili yamaseli ihlanganyela ukushisa okuthululwe esitokisini esivinjiwe, ngakho-ke umonakalo wemojula ovela ekuthululweni kokushisa okuncane nawo uyancipha, okungathuthukisaiphaneli yelangaumonakalo obangelwa izindawo zokushisa.
