1. Ukubuka Konke Kobuchwepheshe Be-Half-Cell
Ubuchwepheshe be-half-cell buhilela ukuhlukanisa amaseli elanga ajwayelekile abe yizingxenye ezimbili ezilinganayo. Ngokungafani namaphaneli elanga avamile anamaseli angu-60 noma angu-72 anosayizi ogcwele, amaphaneli e-half-cell ngokuvamile anezinhlayiya ezingu-120 noma ezingu-144 kuyilapho egcina umklamo nobukhulu obufanayo namaphaneli ajwayelekile.
2. Inqubo Yokusika Isigamu Seseli
Inqubo yokukhiqiza isigamu-seli ngokuvamile isebenzisa ukusika nge-laser, ihlukanisa iseli lelanga elinobukhulu obujwayelekile libe yizingxenye ezimbili ezilinganayo eceleni kwendlela eqondile kuya kuma-busbars amakhulu. Lezi zingxenye zibe sezixhunywa kabusha ngochungechunge ukuze zakhe isekethe ephelele.
3. Izici Zikagesi Zamaseli Angama-Half
Amaphaneli angamaseli ayingxenye ahlanganiswe nengilazi eqinisiwe, i-EVA, kanye nephepha langemuva, elifana namamojula avamile.
Iphaneli yelanga evamile iqukethe amaseli axhunyiwe ochungechungeni angu-60, ngalinye likhiqiza u-0.5–0.6V, kanye ne-voltage yokusebenza ephelele engu-30–35V.
Uma amaseli ayingxenye exhunyiwe njengakwimojuli ejwayelekile, akhiqiza uhhafu wamanje futhi aphinde kabili i-voltage, agcine ukumelana kungaguquki.
Ukuze kufane nomphumela we-voltage kanye nowamanje wamaphaneli avamile, amaphaneli e-half-cell aklanywe ngokucushwa okuhambisana nochungechunge, okuhlanganisa ngempumelelo amamojula amabili amancane ahambisanayo. Lokhu kuqinisekisa ukuthi:
I-half-cell ngayinye ine-open-circuit voltage efanayo ne-full cell.
Ugesi wengxenye ngayinye yeseli uncishiswa phakathi, kodwa umklamo ohambisanayo ubuyisela ugesi ophelele ukuze ufane namamojula eseli eligcwele.
Ukumelana okuphelele kwesekethe kuncishiswe kwaba yingxenye eyodwa kwezine yaleyo module egcwele amaseli, okunciphisa kakhulu ukulahleka kwamandla.
4. Izinzuzo Zobuchwepheshe Be-Half-Cell
① Ukulahlekelwa Okuphansi Kokupakisha
Ngokunciphisa ukumelana kwamandla kagesi angaphakathi kanye nokumelana kwesekethe, ukulahlekelwa kwamandla angaphakathi kuyancishiswa. Ukulahlekelwa kwamandla kuyalingana nokwamanje, ngakho-ke ukunciphisa umkhawulo wamandla kagesi ngesigamu kanye nokunciphisa ukumelana nekota eyodwa kunciphisa ukulahleka kwamandla ngokuphindwe kane. Lokhu kuthuthukisa ukuphuma kwamandla kanye nokukhiqiza kwamandla kwephaneli.
Ukulahlekelwa okuphansi kwangaphakathi kunciphisa izinga lokushisa lokusebenza kwephaneli. Ngaphansi kwezimo zangaphandle, amaphaneli engxenye yeseli asebenza cishe ebanda ngo-1.6°C kunamaphaneli avamile, okuthuthukisa ukusebenza kahle kokuguqulwa.
② Ingozi Encishisiwe Yezindawo Ezishisayo Ezivela Emthunzini
Amaphaneli esigamu samaseli aphatha ukufiphaza kangcono kunamamojula ajwayelekile
Ngokungafani namaphaneli avamile anezintambo ezintathu zamaseli, amaphaneli esigamu samaseli anama-6, asebenza njengamamojula ayisithupha amancane.
Ama-diode adlulayo (aphawulwe ngombala obomvu kumdwebo) ahlukanisa izindawo ezifakwe umthunzi kwezinye izingxenye zephaneli, okunciphisa ukulahleka kokusebenza ngenxa yomthunzi ongaphelele (isib., kusuka emaqabunga noma endle yezinyoni).
Ngisho noma ingxenye yephaneli ifihlwe, enye ingxenye ingaqhubeka nokusebenza, okuqinisekisa ukusebenza kahle okuphezulu.
③ Umswakama Ophansi Wehlisa Izinga Lokushisa Elishisayo
Ubuchwepheshe be-half-cell busabalalisa ugesi ngempumelelo enkulu, buthuthukisa ukusebenza, isikhathi sokuphila, kanye nokubekezelelana komthunzi.
Ezimweni zomthunzi, amangqamuzana athintekile angakha izindawo ezishisayo ngenxa yokushisa okweqile kwendawo.
Amaphaneli angamaseli ayingxenye, anenani eliphindwe kabili lezintambo, athola ingxenye kuphela yokukhiqizwa kokushisa ezindaweni ezishisayo. Lokhu kunciphisa umonakalo, kuthuthukisa ukuqina, futhi kwandise isikhathi sokuphila semojuli.
④ Ukubekezelela Okuthuthukisiwe Kokufiphaza Ukulahlekelwa Amandla
Ku-solar array, amaphaneli amaningi axhunywe ngochungechunge ngaphakathi kwentambo, kanti izintambo zixhunywe ngokulingana.
Emiklamo yephaneli yendabuko, ukulahlekelwa amandla kuphaneli eyodwa enomthunzi kuthinta yonke intambo.
Kumaphaneli e-half-cell, ama-bypass diode adala izindlela ezihlukile zamanje, okuvumela ukuthi ugeleze ezindaweni ezinombala futhi kuncishiswe ukulahleka kwamandla. Lokhu kuthuthukisa ukusebenza futhi kunciphisa umthelela wombala.
Amaphaneli elanga ayingxenye yeseli amelela intuthuko ebalulekile kubuchwepheshe belanga, ehlanganisa ukusebenza kahle okuthuthukisiwe, ukuqina, kanye nokumelana nomthunzi. Umklamo wawo othuthukisiwe uqinisekisa ukusebenza okuthembekile ngisho nangaphansi kwezimo ezinzima, okwenza kube ukukhetha okuthandwayo kwezinhlelo zesimanje ze-photovoltaic.
