Kusamalira ma modules a photovoltaic ndi chitsimikizo chachindunji chowonjezera mphamvu zowonjezera mphamvu ndi kuchepetsa kutaya mphamvu.Ndiye cholinga cha photovoltaic ntchito ndi kukonza ogwira ntchito ndi kuphunzira chidziwitso choyenera cha photovoltaic modules.
Choyamba, ndiloleni ndikuuzeni za kupanga mphamvu za photovoltaic ndi chifukwa chake tikupanga mphamvu zamagetsi za photovoltaic.Chikhalidwe cha dziko la China pakalipano ndi chitukuko cha chilengedwe, kukula kwakukulu ndi kosalamulirika ndi kugwiritsa ntchito mafuta oyaka, sikungowonjezera kutha kwa zinthu zamtengo wapatalizi, komanso kumayambitsa mavuto aakulu kwambiri.Kuwonongeka kwa chilengedwe.
China ndi dziko lomwe limapanga malasha komanso ogula kwambiri padziko lonse lapansi, ndipo pafupifupi 76% ya mphamvu zake zimaperekedwa ndi malasha.Kudalira kochulukira kwa mphamvu yamafuta opangira zinthu zakale kwadzetsa vuto lalikulu pazachilengedwe, zachuma komanso chikhalidwe.Kuchuluka kwa migodi ya malasha, mayendedwe ndi kuwotcha kwawononga kwambiri chilengedwe cha dziko lathu.Choncho, timakulitsa mwamphamvu kugwiritsa ntchito mphamvu zowonjezera mphamvu monga mphamvu ya dzuwa.Ichi ndi chisankho chosapeŵeka cha chitetezo champhamvu cha dziko lathu ndi chitukuko chokhazikika.
Photovoltaic mphamvu yopanga mphamvu yamagetsi
Dongosolo la mphamvu ya photovoltaic makamaka limapangidwa ndi gawo la photovoltaic module, bokosi lophatikizira, inverter, kusintha kwa gawo, kabati yosinthira, ndiyeno dongosolo lomwe silinasinthe, ndipo pomaliza limabwera ku gridi yamagetsi kudzera mizere.Ndiye mfundo ya mphamvu ya photovoltaic ndi yotani?
Kupanga mphamvu kwa Photovoltaic kumachitika makamaka chifukwa cha mphamvu ya Photoelectric ya semiconductors.Photon ikayatsa chitsulo, mphamvu zake zonse zimatha kutengedwa ndi electron muzitsulo.Mphamvu yotengedwa ndi electron ndi yaikulu yokwanira kugonjetsa mphamvu yokoka mkati mwazitsulo ndikuchita ntchito, kusiya pamwamba pazitsulo ndikuthawa kukhala Optoelectronics, maatomu a silicon ali ndi ma elekitironi 4 akunja.Ngati maatomu a phosphorous, omwe ndi ma atomu a phosphorous a atomiki okhala ndi ma elekitironi 5 akunja, alowetsedwa mu silikoni yoyera, semiconductor yamtundu wa n imapangidwa.
Ngati ma atomu okhala ndi ma elekitironi atatu akunja, monga ma atomu a boron, asakanizidwa mu silikoni yoyera kuti apange semiconductor ya p-mtundu, mtundu wa p ndi mtundu wa n ukaphatikizidwa pamodzi, malo olumikizanawo amapanga kusiyana kwa selo ndikukhala solar. selo.
Zithunzi za Photovoltaic
Module ya photovoltaic ndi chipangizo chaching'ono kwambiri chophatikizira ma cell a solar omwe ali ndi pakati ndi maulumikizidwe amkati omwe angapereke kutulutsa kwa DC kokha.Amatchedwanso solar panel.Module ya photovoltaic ndi gawo lalikulu la dongosolo lonse la mphamvu ya photovoltaic.Ntchito yake ndikugwiritsa ntchito mphamvu ya Photoacoustic radiation kuti mphamvu ya Dzuwa imasinthidwa kukhala mphamvu ya DC.Dzuwa likawalira pa cell solar, batire imatenga mphamvu yamagetsi kuti ipange mabowo a photoelectron.Pansi pa mphamvu yamagetsi mu batri, ma electron opangidwa ndi zithunzi ndi ma spins amalekanitsidwa, ndipo kusonkhanitsa kwa milandu ya zizindikiro zosiyanasiyana kumawonekera kumapeto kwa batri.Ndipo pangani kukakamizidwa koyipa kopangidwa ndi zithunzi, zomwe timatcha chithunzi chopangidwa ndi photovoltaic effect.
Ndiroleni ndikudziwitseni module ya polycrystalline silicon photovoltaic yopangidwa ndi kampani inayake.Mtundu uwu uli ndi mphamvu yogwiritsira ntchito 30.47 volts ndi mphamvu yapamwamba ya 255 Watts.Mwa kuyamwa mphamvu ya dzuwa, mphamvu ya dzuwa imasinthidwa mwachindunji kapena mosalunjika kukhala mphamvu yamagetsi kudzera muzithunzithunzi za photoelectric kapena photochemical effect.Pangani magetsi.
Poyerekeza ndi zida za silicon za monocrystalline, zida za silicon za polycrystalline ndizosavuta kupanga, kupulumutsa mphamvu, ndipo zimakhala ndi ndalama zotsika kwambiri zopangira, koma kutembenuka kwazithunzi kumakhalanso kochepa.
Ma module a Photovoltaic amatha kupanga magetsi pansi pa dzuwa.Ndi zotetezeka komanso zodalirika, zilibe phokoso komanso sizitulutsa mpweya woipa, ndipo ndi aukhondo kotheratu komanso osawononga chilengedwe.
Kenako, timayambitsa mawonekedwe a chipangizocho ndikuchichotsa.
Junction Box
Bokosi la photovoltaic junction ndi cholumikizira pakati pa ma cell a solar omwe amapangidwa ndi ma module a solar cell ndi chipangizo chowongolera chowongolera.Zimagwirizanitsa kwambiri mphamvu yamagetsi yopangidwa ndi maselo a dzuwa ndi maulendo akunja.
Glass Wotentha
Kugwiritsiridwa ntchito kwa magalasi otsekemera omwe ali ndi kuwala kwakukulu kumateteza makamaka kuteteza maselo a batri kuti asawonongeke, omwe ali ofanana ndi Jian Bai akunena kuti filimu yathu yotentha ya foni yam'manja imakhala ndi chitetezo.
Encapsulation
Chifukwa filimuyi imagwiritsidwa ntchito makamaka kugwirizanitsa ndi kukonza magalasi otenthedwa ndi maselo a batri, imakhala yowonekera kwambiri, yosinthasintha, yotsika kwambiri kutentha ndi kukana madzi.
Chophimba cha malata chimagwiritsidwa ntchito makamaka kulumikiza mabatire abwino ndi oipa kuti apange chigawo chotsatira, chomwe chimapanga mphamvu zamagetsi ndikuzitsogolera ku bokosi lolowera.
Aluminium Alloy Frame
Chojambula cha photovoltaic module chimapangidwa ndi rectangular aluminium alloy, yomwe imakhala yopepuka komanso yolemetsa.Amagwiritsidwa ntchito makamaka kuteteza crimping wosanjikiza ndikuchita gawo linalake losindikiza ndi kuthandizira, lomwe ndilo maziko a selo.
Maselo a dzuwa a Polycrystalline Silicon
Maselo a dzuwa a polycrystalline silicon ndiye chigawo chachikulu cha module.Ntchito yawo yayikulu ndikutembenuza ma photoelectric ndikupanga mphamvu zambiri zamagetsi.Maselo a solar crystalline silicon ali ndi ubwino wa mtengo wotsika komanso msonkhano wosavuta.
Ndege yakumbuyo
Tsamba lakumbuyo limagwirizana mwachindunji ndi chilengedwe chakunja kumbuyo kwa gawo la photovoltaic.Zida zopangira ma photovoltaic zimagwiritsidwa ntchito makamaka kuyika zigawozo, kuteteza zipangizo zaiwisi ndi zothandizira, ndikupatula ma modules a dzuwa kuchokera ku lamba wobwereranso.Chigawochi chimakhala ndi zinthu zabwino monga kukana kukalamba, kukana kutsekereza, kukana madzi, komanso kukana gasi.Mawonekedwe.
Mapeto
Mzere waukulu wa chimango cha gawo la photovoltaic umapangidwa ndi galasi lotentha la photovoltaic lomwe lili ndi filimu yaying'ono, maselo, mipiringidzo ya malata, mafelemu a aluminiyamu aloyi, ndi mabokosi ophatikizira kumbuyo kuti apange mapulagi a SC ndi zigawo zina zazikulu.
Pakati pawo, maselo a crystalline silicon amagwirizanitsidwa kuti agwirizane ndi maselo angapo kutsogolo ndi kubwereranso kuti apange mgwirizano wotsatizana, ndiyeno amatsogoleredwa ku bokosi lolumikizana kudzera mu lamba wa basi kuti apange gawo la batri lamagetsi apamwamba kwambiri.Pamene kuwala kwa dzuwa kumayikidwa pamwamba pa module, bolodi imapanga panopa kupyolera mu kutembenuka kwa magetsi., mayendedwe apano akuyenda kuchokera ku electrode yabwino kupita ku electrode yoyipa.Pamwamba ndi pansi pa selo pali filimu yamtundu umodzi yomwe imakhala ngati zomatira.Pamwamba pake ndi powonekera kwambiri komanso osagwira mtima.Kumbuyo kwa galasi ndi backsheet ya PPT yomwe yapangidwa ndi kutentha ndi kupukuta.Chifukwa PPT ndi galasi zimasungunuka mu cell cell ndikutsatiridwa kwathunthu.Chophimba cha aluminiyamu chimagwiritsidwa ntchito kusindikiza m'mphepete mwa module ndi silicone.Pali mabasi otsogolera kumbuyo kwa gulu la cell.Bokosi lotsogolera la batri limakhazikitsidwa ndi kukana kutentha kwakukulu.Tangowonjezera zida za module ya photovoltaic kudzera mu disassembly.Kapangidwe ndi mfundo ntchito.
