Kuwerengera mphamvu, mphamvu zopangira mphamvu komanso moyo wautumiki wa mapanelo adzuwa

Solar panel ndi chipangizo chomwe chimatembenuza ma radiation a dzuwa mwachindunji kapena mosalunjika kukhala mphamvu yamagetsi kudzera mumphamvu ya photoelectric kapena photochemical effect potengera kuwala kwa dzuwa.Chinthu chachikulu cha mapanelo ambiri a dzuwa ndi "silicon".Ma photons amatengedwa ndi zinthu za silicon;mphamvu ya ma photon imasamutsidwa ku ma atomu a silicon, zomwe zimapangitsa kuti ma electron asinthe ndikukhala ma electron aulere omwe amasonkhana kumbali zonse za PN mphambano kuti apange kusiyana komwe kungatheke.Pamene dera lakunja liyatsidwa, pansi pa machitidwe a voteji iyi, Padzakhala pakalipano ikuyenda kudutsa kunja kuti apange mphamvu inayake.Chofunikira cha njirayi ndi: njira yosinthira mphamvu ya photon kukhala mphamvu yamagetsi.

Kuwerengera Mphamvu ya Solar Panel

Dongosolo lamagetsi la solar AC limapangidwa ndi solar panel, control controller, inverters ndi mabatire;makina opangira magetsi a solar DC samaphatikizapo inverter.Pofuna kuti mphamvu yopangira mphamvu ya dzuwa ipereke mphamvu zokwanira zonyamula katundu, m'pofunika kusankha mwanzeru chigawo chilichonse malinga ndi mphamvu ya chipangizo chamagetsi.Tengani mphamvu yotulutsa 100W ndikuigwiritsa ntchito kwa maola 6 patsiku monga chitsanzo pofotokozera njira yowerengera:

1. Choyamba, kuwerengera kuchuluka kwa ola lawatt patsiku (kuphatikiza kutayika kwa inverter): ngati kutembenuka kwamphamvu kwa inverter ndi 90%, ndiye pamene mphamvu yotulutsa ndi 100W, mphamvu yeniyeni yotulutsa iyenera kukhala 100W / 90% =111W;ngati ikugwiritsidwa ntchito kwa maola 5 patsiku, mphamvu yotulutsa ndi 111W * 5 hours = 555Wh.

2. Werengani gulu la solar: Malingana ndi nthawi ya dzuwa ya tsiku ndi tsiku ya maola 6, ndipo poganizira momwe kuliritsira bwino komanso kutayika panthawi yoyendetsa, mphamvu yotulutsa mphamvu ya solar panel iyenera kukhala 555Wh / 6h / 70% = 130W.Pakati pawo, 70% ndi mphamvu yeniyeni yomwe imagwiritsidwa ntchito ndi solar panel panthawi yolipira.

Mphamvu yopangira mphamvu ya solar panel

Kuthekera kwa kutembenuka kwa zithunzi za monocrystalline silicon solar energy kumafika ku 24%, komwe ndi njira yabwino kwambiri yosinthira zithunzi pakati pa mitundu yonse ya ma cell a solar.Koma ma cell a solar a monocrystalline silicon ndi okwera mtengo kwambiri kotero kuti sanagwiritsidwebe ntchito mochuluka komanso padziko lonse lapansi.Ma cell a solar a polycrystalline silicon ndi otsika mtengo kuposa ma cell a solar a monocrystalline silicon potengera mtengo wopangira, koma kutembenuka kwa photoelectric kwa ma cell a solar a polycrystalline silicon ndikotsika kwambiri.Kuphatikiza apo, moyo wautumiki wa ma cell a solar a polycrystalline silicon ndiwofupika kuposa ma cell a solar a monocrystalline silicon..Choncho, ponena za ntchito yamtengo wapatali, maselo a dzuwa a monocrystalline silicon ndi abwinoko pang'ono.

Ofufuza apeza kuti zida zina zopangira semiconductor ndizoyenera makanema otembenuza ma solar photoelectric.Mwachitsanzo, CdS, CdTe;III-V pawiri semiconductors: GaAs, AIPInP, etc.;filimu yopyapyala yopangidwa ndi ma semiconductors amawonetsa bwino kutembenuka kwazithunzi.Zipangizo za semiconductor zokhala ndi mipata yambiri yama gradient mphamvu zamagetsi zimatha kukulitsa mawonekedwe owoneka bwino a mayamwidwe amphamvu yadzuwa, potero kuwongolera kusinthika kwazithunzi.Kotero kuti chiwerengero chachikulu cha ntchito zothandiza za maselo a solar opyapyala amasonyeza chiyembekezo chachikulu.Zina mwa zida za semiconductor zamitundu yambiri, Cu(In,Ga) Se2 ndi chinthu chabwino kwambiri choyamwa ndi kuwala kwa dzuwa.Kutengera izi, ma cell a solar amtundu wocheperako omwe ali ndi mawonekedwe apamwamba kwambiri a photoelectric kuposa silicon angapangidwe, ndipo kutembenuka kwa photoelectric komwe kungapezeke ndi 18%.

Kutalika kwa moyo wa mapanelo a dzuwa

Moyo wautumiki wa mapanelo a dzuwa umatsimikiziridwa ndi zipangizo zamaselo, magalasi otsekemera, EVA, TPT, ndi zina zotero. ma cell a dzuwa Zinthu za bolodi zidzakalamba pakapita nthawi.Nthawi zonse, mphamvuyo idzachepetsedwa ndi 30% pambuyo pa zaka 20 zogwiritsidwa ntchito, ndi 70% pambuyo pa zaka 25 zogwiritsidwa ntchito.
