Iphaneli yelanga iyithuluzi eliguqula imisebe yelanga ngokuqondile noma ngokungaqondile ibe amandla kagesi ngomphumela wesithombe sikagesi noma umphumela we-photochemical ngokumunca ukukhanya kwelanga.Izinto eziyinhloko zama-solar panel amaningi "i-silicon".Ama-photon amuncwa izinto ze-silicon;amandla ama-photon adluliselwa kuma-athomu e-silicon, okwenza ama-electron aguquke futhi abe ama-electron amahhala aqoqana ezinhlangothini zombili ze-PN junction ukuze enze umehluko ongaba khona.Lapho isifunda sangaphandle sivuliwe, ngaphansi kwesenzo sale voltage, i-Kuzoba khona okwamanje egeleza kwisekethe yangaphandle ukuze kukhiqizwe amandla athile okukhipha.Ingqikithi yale nqubo: inqubo yokuguqula amandla e-photon abe amandla kagesi.
I-Solar Panel Power Calculation
Uhlelo lokukhiqiza amandla elanga le-AC lwakhiwe ngamaphaneli elanga, izilawuli zokushaja, ama-inverter namabhethri;uhlelo lokuphehla amandla elanga le-DC alufaki i-inverter.Ukuze unike amandla uhlelo lokuphehla amandla elanga ukuze lunikeze amandla anele omthwalo, kuyadingeka ukukhetha ngokunengqondo ingxenye ngayinye ngokwamandla omshini kagesi.Thatha amandla okukhipha angu-100W futhi uwasebenzise amahora angu-6 ngosuku njengesibonelo ukwethula indlela yokubala:
1. Okokuqala, bala ukusetshenziswa kwehora le-watt ngosuku (kuhlanganise nokulahlekelwa kwe-inverter): uma ukusebenza kahle kokuguqulwa kwe-inverter kungu-90%, khona-ke lapho amandla okukhiphayo engu-100W, amandla okuphuma kwangempela kufanele abe ngu-100W / 90 % =111W;uma isetshenziswa amahora angu-5 ngosuku, amandla okukhipha angu-111W*5 amahora=555Wh.
2. Bala iphaneli yelanga: Ngokwesikhathi sokukhanya kwelanga esisebenzayo nsuku zonke samahora angu-6, futhi ucabangela ukusebenza kahle kokushaja nokulahlekelwa phakathi nenqubo yokushaja, amandla okukhipha ephaneli yelanga kufanele abe ngu-555Wh/6h/70%=130W.Phakathi kwazo, i-70% ingamandla wangempela asetshenziswa iphaneli yelanga ngesikhathi sokushaja.
Ukusebenza kahle kokukhiqiza amandla ephaneli yelanga
Ukusebenza kahle kokuguqulwa kwe-photoelectric kwe-monocrystalline silicon amandla elanga afinyelela ku-24%, okuyindlela ephakeme kakhulu yokuguqula isithombe sikagesi phakathi kwazo zonke izinhlobo zamaseli elanga.Kodwa amaseli elanga e-silicon e-monocrystalline abiza kakhulu ukuzenza kangangokuthi awakakasetshenziswa kabanzi futhi emhlabeni wonke ngamanani amakhulu.Amaseli elanga e-polycrystalline silicon ashibhile kunamaseli elanga e-monocrystalline silicon ngokwezindleko zokukhiqiza, kodwa ukusebenza kahle kokuguqulwa kwe-photoelectric kwamaseli elanga e-polycrystalline silicon kuphansi kakhulu.Ngaphezu kwalokho, impilo yesevisi yamaseli elanga e-polycrystalline silicon nayo imfushane kunaleyo yamaseli elanga elanga e-silicon ye-monocrystalline..Ngakho-ke, mayelana nokusebenza kwezindleko, amaseli elanga e-silicon e-monocrystalline angcono kancane.
Abacwaningi bathole ukuthi ezinye izinto ezihlanganisiwe ze-semiconductor zifanele amafilimu okuguqula ama-solar photoelectric.Isibonelo, i-CdS, i-CdTe;I-III-V semiconductors ehlanganisiwe: I-GaAs, i-AIPInP, njll.;amaseli elanga amancane efilimu enziwe ngalawa ma-semiconductors abonisa ukusebenza kahle kokuguqulwa kwe-photoelectric.Izinto zokwakha ze-Semiconductor ezinezikhala eziningi ze-gradient energy band zinganweba uhla lwe-spectral lokumuncwa kwamandla elanga, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokuguqulwa kwe-photoelectric.Ukuze inani elikhulu lezinhlelo zokusebenza ezisebenzayo zamaseli elanga acwebezelayo abonise amathemba abanzi.Phakathi kwalezi zinto ezinezingxenye eziningi ze-semiconductor, i-Cu(In,Ga) Se2 iyinto enhle kakhulu emunca ukukhanya kwelanga.Ngokusekelwe kulo, amaseli elanga anefilimu emincane esebenza kahle kakhulu yokuguqulwa kwesithombe sikagesi kune-silicon engaklanywa, futhi izinga lokuguqulwa kwe-photoelectric elingafinyelelwa liyi-18%.
Ukuphila kwamaphaneli elanga
Ukuphila kwenkonzo yamapaneli elanga kunqunywa izinto zamaseli, ingilazi epholile, i-EVA, i-TPT, njll. Ngokuvamile, impilo yesevisi yamapaneli enziwe abakhiqizi abasebenzisa izinto ezingcono kakhulu ingafinyelela eminyakeni engu-25, kodwa ngomthelela wemvelo, amaseli elanga Izinto zebhodi zizoguga ngokuhamba kwesikhathi.Ngaphansi kwezimo ezijwayelekile, amandla azoncishiswa ngo-30% ngemva kweminyaka engu-20 esetshenziswa, futhi ngo-70% ngemva kweminyaka engu-25 esetshenziswa.
