Eyona teknoloji isebenzayo yephaneli yelanga

Imfuno yamandla avuselelekayo iye yanda ngenxa yeenkxalabo ezikhulayo malunga nemiba yokusingqongileyo kunye nesidingo sokukhethwa kwamandla azinzileyo. Itekhnoloji yephaneli yelanga ibe lukhetho oludumileyo lokusebenzisa amandla amaninzi elanga ukwenza umbane. Njengoko ihlabathi liqhubeka nokutyala imali kumandla elanga, ukufuna eyona teknoloji isebenzayo yephaneli yelanga iya ibaluleke kakhulu. Kweli nqaku, siza kuphonononga iintlobo ezahlukeneyo zobuchwepheshe bephaneli yelanga kunye nezona ndlela zisebenzayo ezikhoyo namhlanje.

Itekhnoloji yephaneli yelanga igubungela izinto ezahlukeneyo kunye noyilo, kodwa ezona ntlobo zixhaphakileyo zephaneli yelanga ziquka i-monocrystalline, i-polycrystalline, kunye neepaneli zelanga ezicwebileyo. Uhlobo ngalunye lunezibonelelo zalo kunye nokungonakali, kwaye ukusebenza kakuhle kweepaneli kunokuhluka ngokusekelwe kwizinto ezifana neendleko, iimfuno zofakelo, kunye nokusebenza phantsi kweemeko ezahlukeneyo zokusingqongileyo.

Iiphaneli zelanga ze-Monocrystallinezenziwe kwi-crystal structure enye eqhubekayo, ebanika ukubonakala okufanayo kunye nokusebenza okuphezulu. Ezi panel ziyaziwa ngenkangeleko yazo emnyama enesitayile kunye nemveliso yamandla aphezulu. Iiphaneli zelanga ze-Polycrystalline, kwelinye icala, zenziwe ngeekristale ezininzi ze-silicon, zizenza zifanane ngokubonakalayo kwaye zingasebenzi kakuhle kuneepaneli ze-monocrystalline. Iipaneli zelanga ze-Thin-film zenziwa ngokubeka iileyile ezincinci zezinto ze-photovoltaic kwi-substrate, kwaye ngelixa zingasebenzi kakuhle kuneepaneli ze-crystalline, ziguquguquka ngakumbi kwaye zilula, zibenza zilungele izicelo ezithile.

Iipaneli zelanga ze-Monocrystalline sele zithathwa njengeyona ndlela isebenzayo ngokufanelekileyo. Ezi panels zinemilinganiselo ephezulu yokusebenza kwaye ziyakwazi ukuguqula ukukhanya kwelanga kumbane xa kuthelekiswa ne-polycrystalline kunye neepaneli zefilimu ezincinci. Oku kuthetha ukuba indawo encinci yepaneli ye-monocrystalline iyadingeka ukuvelisa umlinganiselo ofanayo wombane njengendawo enkulu yepolycrystalline okanye ipaneli yefilimu encinci. Ngenxa yoko, iiphaneli ze-silicon ze-monocrystalline zihlala zithandwa kwindawo yokuhlala kunye nofakelo lwentengiso olunendawo encinci.

Nangona kunjalo, ishishini lelanga lihlala livela, kwaye itekhnoloji entsha iyavela ecela umngeni kulawulo lwemveli lweepaneli ze-monocrystalline. Enye iteknoloji enjalo kukuphuhliswa kwe-PERC (i-emitter passivated kunye ne-back cell cell) iiseli zelanga, ezijolise ekunyuseni ukusebenza kakuhle kweepaneli zelanga ze-monocrystalline kunye ne-polycrystalline. Ngokudibanisa i-passivation layer kumqolo ongemva weseli yelanga, itekhnoloji ye-PERC iyanciphisa ukudityaniswa kwakhona kwee-electron kwaye yandisa ukusebenza kakuhle kweseli. Le nkqubela phambili ivumele iiphaneli ze-monocrystalline kunye ne-polycrystalline ukuba zisebenze ngakumbi, zibenze bakhuphisane ngakumbi kunye neepaneli zefilimu ezincinci.

Olunye uphuculo oluthembisayo kwitekhnoloji yephaneli yelanga kukusetyenziswa kweephaneli zelanga ze-bifacial, ezibamba ukukhanya kwelanga kwindawo yangaphambili nasemva kwephaneli. Iiphaneli ezinamacala amabini zisebenzisa ukukhanya kwelanga okuvezwa emhlabeni okanye kumphezulu okufutshane ukuvelisa umbane owongezelelweyo xa kuthelekiswa neepaneli zesiqhelo ezicalanye. Ithekhnoloji inamandla okuphucula ngakumbi ukusebenza kakuhle kweepaneli zelanga, ngakumbi kwiindawo ezine-albedo ephezulu okanye i-reflection surfaces.

Ukongeza kwezi nkqubela phambili, abaphandi bahlola izinto ezintsha kunye noyilo lweepaneli zelanga, ezifana neeseli zelanga ze-perovskite kunye neeseli zelanga ezininzi, ezinokuthi zigqithise ukusebenza kakuhle kweepaneli zelanga ezisekelwe kwi-silicon. Iiseli zelanga ze-Perovskite, ngokukodwa, zibonisa isithembiso esikhulu kwizicwangciso zebhubhoratri, kunye nezinye iiprototypes ezifezekisa ukusebenza okungaphezulu kwe-25%. Ngelixa ukuthengiswa kwezi teknoloji kusekho kwisigaba sophando kunye nophuhliso, banakho ukuguqula imboni yelanga kunye nokwenza amandla elanga akhuphisane ngakumbi kunemithombo yamandla endabuko.

Isishwankathelo, ukukhangela iteknoloji yephaneli yelanga esebenzayo kakhulu iyaqhubeka, kunye nenkqubela phambili kwitekhnoloji ye-PERC, iipaneli ze-bifacial, kunye nezixhobo ezivelayo ezibonelela ngamathuba amatsha okuphucula ukusebenza kakuhle kweepaneli zelanga. Ngelixa iiphaneli ze-silicon ze-monocrystalline kudala zijongwa njengeyona ndlela isebenzayo, ukutsha okukhawulezayo kwishishini lelanga kunomngeni kwizithethe zemveli kunye nokuvula umnyango kumathuba amatsha. Njengoko ihlabathi liqhubeka nokutshintshela kumandla ahlaziyekayo, uphuhliso lwetekhnoloji yephaneli yelanga luya kudlala indima ephambili ekuqhubeni ukwamkelwa kwamandla elanga kunye nokunciphisa ukuthembela kwethu kumafutha efosili.

Ukuba unomdla kwiiphaneli zelanga ze-monocrystalline, wamkelekile ukuba uqhagamshelane nenkampani yelanga yaseChina iRadiance Radiance ukuyafumana isicatshulwa.
