Iphaneli yelanga sisixhobo esiguqula imitha yelanga ngokuthe ngqo okanye ngokungathanga ngqo kumandla ombane ngesiphumo sombane okanye isiphumo sefotochemical ngokufunxa ukukhanya kwelanga.Izinto eziphambili kwiipaneli ezininzi zelanga "i-silicon".Iifotoni zifunxwa zizinto ze-silicon;amandla eefotoni adluliselwa kwii-athom ze-silicon, okwenza ukuba ii-electron ziguquke kwaye zibe yi-electron yamahhala eqokelela kumacala omabini e-PN junction ukwenza umahluko onokubakho.Xa isiphaluka sangaphandle sivuliwe, phantsi kwesenzo salo mbane, kuya kubakho ngoku ohambayo kwisiphaluka sangaphandle ukuvelisa amandla athile okuvelisa.Ingundoqo yale nkqubo kukuba: inkqubo yokuguqula amandla e-photon kumandla ombane.
ISolar Panel Power Calculation
Inkqubo yokuvelisa amandla elanga ye-AC yenziwe ngeepaneli zelanga, izilawuli zentlawulo, ii-inverters kunye neebhetri;inkqubo yokuvelisa amandla elanga yeDC ayiquki i-inverter.Ukwenzela ukuba inkqubo yokuvelisa amandla elanga inike amandla okwaneleyo kumthwalo, kuyimfuneko ukuba ukhethe ngokufanelekileyo icandelo ngalinye ngokwamandla ombane wombane.Thatha i-100W yokukhupha amandla kwaye uyisebenzise kwiiyure ze-6 ngosuku njengomzekelo ukwazisa indlela yokubala:
1. Okokuqala, bala ukusetyenziswa kweyure ye-watt ngosuku (kubandakanywa nokulahlekelwa kwe-inverter): ukuba ukuguqulwa kokuguqulwa kwe-inverter yi-90%, ngoko xa umbane ophumayo ngu-100W, amandla okuvelisa ngokwenene kufuneka abe yi-100W / 90% =111W;ukuba isetyenziselwa iiyure ezi-5 ngosuku, amandla aphumayo yi-111W * 5 iiyure = 555Wh.
2. Bala iphaneli yelanga: Ngokwexesha lelanga elisebenzayo lemihla ngemihla leeyure ze-6, kunye nokuqwalasela ukusebenza kakuhle kokutshaja kunye nokulahleka ngexesha lenkqubo yokutshaja, amandla okukhutshwa kwepaneli yelanga kufuneka abe yi-555Wh / 6h / 70% = 130W.Phakathi kwabo, i-70% ngamandla okwenene asetyenziswa yipaneli yelanga ngexesha lenkqubo yokutshaja.
Ukwenziwa kombane kwiphaneli yelanga
Ukusebenza kokuguqulwa kwe-photoelectric ye-monocrystalline silicon yamandla elanga ukuya kuthi ga kwi-24%, eyona nto iphezulu yokuguqulwa kweefoto zombane phakathi kwazo zonke iintlobo zeeseli zelanga.Kodwa iiseli ze-silicon ze-monocrystalline zelanga zibiza kakhulu ukuzenza kangangokuba azikasetyenziswa ngokubanzi kwaye zisetyenziswe ngokubanzi ngamanani amakhulu.Iiseli zelanga ze-polycrystalline silicon zinexabiso eliphantsi kuneeseli zelanga ze-silicon ze-monocrystalline ngokwexabiso lemveliso, kodwa ukusebenza kakuhle kokuguqulwa kwe-photoelectric yeeseli zelanga ze-polycrystalline silicon kuphantsi kakhulu.Ukongeza, ubomi benkonzo yeeseli zelanga ze-polycrystalline silicon bufutshane kunobo beeseli zelanga ze-silicon ze-monocrystalline..Ke ngoko, malunga nokusebenza kweendleko, iiseli zelanga ze-silicon ze-monocrystalline zingcono kancinci.
Abaphandi baye bafumanisa ukuba ezinye izinto eziphathekayo ze-semiconductor zifanelekile kwiifilimu zokuguqula i-solar photoelectric.Umzekelo, CdS, CdTe;I-III-V i-semiconductors edibeneyo: i-GaAs, i-AIPInP, njl.;iiseli zelanga zefilimu ezibhityileyo ezenziwe zezi semiconductors zibonisa ukusebenza kakuhle koguqulo lweefoto zombane.Izixhobo zeSemiconductor ezinezithuba ezininzi zebhanti yamandla egradient inokwandisa uluhlu lwembonakalo yokufunxa amandla elanga, ngaloo ndlela iphucula ukusebenza kakuhle koguqulo lombane.Ukwenzela ukuba inani elikhulu lezicelo ezisebenzayo zeeseli zelanga zefilimu ezincinci zibonise amathemba abanzi.Phakathi kwezi zixhobo zesemiconductor enamacandelo amaninzi, iCu(In,Ga) Se2 yeyona nto ibalaseleyo efunxa ukukhanya kwelanga.Ngokusekwe kuyo, iiseli zelanga ezicwebezelayo ezineefoto zombane eziphezulu kakhulu kune-silicon inokuyilwa, kwaye izinga lokuguqulwa kweefoto zombane elinokufikelelwa li-18%.
Ubomi beepaneli zelanga
Ubomi benkonzo yeepaneli zelanga bunqunywe yizinto zeeseli, i-glass tempered, i-EVA, i-TPT, njl. Ngokuqhelekileyo, ubomi benkonzo yeepaneli ezenziwe ngabavelisi abasebenzisa izinto ezingcono banokufikelela kwiminyaka engama-25, kodwa ngempembelelo yendalo, iiseli zelanga Izinto zebhodi ziya kuguga ngokuhamba kwexesha.Kwiimeko eziqhelekileyo, amandla aya kuthotywa nge-30% emva kweminyaka engama-20 yokusetyenziswa, kunye ne-70% emva kweminyaka engama-25 yokusetyenziswa.
