Ukuze kuhlangatshezwane nesidingo esikhulayo samandla, imboni yezamandla entsha iye yadlondlobala eminyakeni emihlanu edlule.Phakathi kwabo, imboni ye-Photovoltaic isibe yindawo eshisayo embonini yamandla entsha ngenxa yokuthembeka nokuzinza kwayo, impilo ende yenkonzo nokufakwa kalula.Uma usanda kuba nombono wokuthenga amaphaneli elanga noma imojula ye-pv, kodwa ungazi ukuthi ungakhetha kanjani.Ake ubheke lesi sihloko.
Ulwazi oluyisisekelo lwamaphaneli elanga:
Ama-solar panel empeleni angamathuluzi ayevame ukubamba amandla avela elangeni, amunca ukukhanya kwelanga futhi akhiqize ugesi ngokuguqula i-photon ibe yi-electron, futhi leyo nqubo ibizwa ngokuthi umphumela we-Photovoltaic.Lapho ukukhanya kwelanga kukhanya kuphaneli yelanga, ama-photoelectrons kumaphaneli akhuthazwa imisebe yelanga, ewavumela ukuba akhe amapheya e-photoelectron.I-electron eyodwa igeleza ku-anode kanti enye i-electron igeleza ku-cathode, yenza indlela yamanje.Amaphaneli e-Silicon anempilo yesevisi engaphezu kweminyaka engu-25, kodwa ngokwanda kokusetshenziswa kwamahora, ukusebenza kahle kwawo kuzokwehla ngesivinini esingaba ngu-0.8% ngonyaka.Ngakho-ke ungakhathazeki, ngisho nangemva kokusetshenziswa kweminyaka eyi-10, amaphaneli akho asagcina ukusebenza okuphezulu kokukhiphayo.
Namuhla, imikhiqizo ejwayelekile emakethe ifaka amaphaneli e-monocrystalline, amaphaneli e-polycrystalline, amaphaneli e-PERC namaphaneli amafilimu amancane.
Phakathi kwalezo zinhlobo zamaphaneli elanga, amaphaneli e-monocrystalline asebenza kahle kakhulu kodwa futhi abiza kakhulu.Lokhu kungenxa yenqubo yokukhiqiza - ngoba amaseli elanga enziwa ngamakristalu e-silicon ngamanye, abakhiqizi kufanele bathwale izindleko zokwenza lawo makristalu.Le nqubo, eyaziwa ngokuthi inqubo ye-Czochralase, inamandla amakhulu futhi idala imfucuza ye-silicon (engase isetshenziselwe ukwenza amaseli elanga e-polycrystalline).
Nakuba kubiza kakhulu kunamaphaneli e-polycrystalline, iyasebenza futhi isebenza kahle kakhulu.Ngenxa yokusebenzisana kwe-silicon ekhanyayo nemsulwa, amaphaneli e-monocrystalline avela ngomnyama, futhi ngokuvamile amhlophe noma amnyama ngemuva.Uma kuqhathaniswa namanye amaphaneli, inokumelana nokushisa okuphezulu, futhi ikhiqize amandla amaningi ngaphansi kokushisa okuphezulu.Kodwa ngokuthuthukiswa kobuchwepheshe kanye nokwenza ngcono ukukhiqizwa kwe-silicon, amaphaneli e-monocrystallien abe umkhiqizo ovamile emakethe.Isizathu siwumkhawulo we-silicon ye-polycrystalline ekusebenzeni kahle, engafinyelela kuphela ku-20% ephezulu, kuyilapho ukusebenza kahle kwamapaneli e-monocrystalline ngokuvamile ku-21-24%.Futhi igebe lentengo phakathi kwabo liyancipha, ngakho-ke, amaphaneli e-monocrystalline ayindlela engcono kakhulu yendawo yonke.
Amaphaneli e-Polycrystalline enziwe nge-silicon wafer, eyenza inqubo yokukhiqiza amabhethri ibe lula--izindleko eziphansi, intengo ephansi.Ngokungafani namaphaneli e-monocrystalline, iseli lamaphaneli e-polycrystalline aluhlaza okwesibhakabhaka ngenkathi ebonisa ukukhanya.Lowo umehluko phakathi kwezingcezu ze-silicon ne-silicon crystal ehlanzekile ngombala.
I-PERC imele i-Passivated Emitter kanye ne-Rear Cell, futhi ebizwa ngokuthi 'i-rear cell', ekhiqizwa ngobuchwepheshe obuphambili.Lolu hlobo lwephaneli yelanga lusebenza kahle kakhulu ngokungeza ungqimba ngemuva kwamaseli elanga.Amaphaneli elanga avamile amunca ukukhanya kwelanga ngezinga elithile kuphela, futhi okunye ukukhanya kudlula kuwo ngokuqondile.Isendlalelo esengeziwe kuphaneli yelanga ye-PERC singamunca ukukhanya okudlulayo futhi futhi sithuthukise ukusebenza kahle.Ubuchwepheshe be-PERC buvame ukusetshenziswa kumaphaneli e-monocrystalline, futhi amandla ayo alinganisiwe aphakeme kakhulu phakathi kwamaphaneli elanga emakethe.
Ihluke kumaphaneli e-monocrystalline kanye namaphaneli e-polycrystalline, amaphaneli amafilimu amancane enziwe ngezinye izinto, ikakhulukazi mayelana: i-cadmium telluride (CdTe) ne-copper indium gallium selenide (CIGS).Lezi zinto zifakwa engilazini noma ezindizeni zangemuva zepulasitiki esikhundleni se-silicon, okwenza kube lula ukufaka amaphaneli amafilimu amancane.Ngakho-ke, ungagcina izindleko eziningi zokufaka.Kodwa ukusebenza kwayo ngokusebenza kahle kubi kakhulu, ngokusebenza kahle kakhulu kwe-15% kuphela.Ngaphezu kwalokho, inokuphila okufushane okuqhathaniswa namaphaneli e-monocrystalline namaphaneli e-polycrystalline.
Ungakhetha kanjani amapaneli afanele?
Kuya ngezidingo zakho kanye nendawo oyisebenzisa kuyo.
Okokuqala, uma ungumsebenzisi wendawo yokuhlala futhi unendawo elinganiselwe yokubeka isistimu yephaneli yelanga.Khona-ke amaphaneli elanga asebenza kahle kakhulu njengamaphaneli e-monocrystalline noma amaphaneli e-monocrystalline e-PERC azoba ngcono.Anamandla okukhipha aphezulu ngakho-ke ukukhetha okuhle kakhulu kwendawo encane ukukhulisa umthamo.Uma ucasulwa yizikweletu eziphakeme zikagesi noma ukuthathe njengokutshala imali ngokuthengisa ugesi ezinkampanini zamandla kagesi, amaphaneli e-monocrystalline ngeke akuvumele.Nakuba kubiza ngaphezu kwamaphaneli e-polycrystalline esigabeni sangaphambilini, kodwa ngokuhamba kwesikhathi, inikeza umthamo ophakeme futhi ikusiza ukuthi wehlise izikweletu zakho kugesi.Lapho umholo wakho ekulondolozeni izikweletu nokudayisa ugesi (uma isiguquli segesi sikugridi) simboza izindleko zesethi yamadivayisi e-photovoltaic, ungakwazi ngisho ukukhokhelwa ngokuthengisa ugesi.Le nketho iyasebenza nasezimbonini noma kumabhilidi okuhweba anqunyelwe indawo.
Isimo sokufaka amaphaneli e-polycrystalline ngokusobala siphambene.Ngenxa yezindleko eziphansi, iyasebenza ezimbonini noma ezakhiweni zezentengiselwano ezinendawo eyanele yokufaka amaphaneli.Ngoba lezi zikhungo zinezindawo ezanele zokubeka ama-solar panel ukwenza ukuntuleka kokusebenza kahle.Kulolu hlobo lwesimo, amaphaneli e-polycrystalline anikeza ukusebenza kwezindleko ezinhle.
Ngokuqondene nama-panels amafilimu amancane, ngokuvamile asetshenziselwa iphrojekthi yezinsiza ezinkulu ngenxa yezindleko zabo eziphansi nokusebenza kahle noma uphahla lwezakhiwo ezinkulu zezentengiselwano ezingakwazi ukusekela isisindo samapaneli elanga.Noma ungazibeka Ezimotweni Zokungcebeleka nasezikebheni 'njengesitshalo esiphathekayo'.
Sekukonke, khetha ngokucophelela lapho uthenga ama-solar panel, njengoba ubude bawo bungafinyelela eminyakeni engu-20 ngokwesilinganiso.Kodwa akunzima njengoba ucabanga, ngokusho nje izinzuzo kanye nebubi uhlobo ngalunye panel solar, futhi uhlanganise nezidingo zakho siqu, khona-ke ungathola impendulo ephelele.
