Mtengo wa zipangizo za dzuwa watsika ndi 89% kuyambira 2010. Kodi idzapitirizabe kukhala yotsika mtengo?
Ngati muli ndi chidwi ndi mphamvu zadzuwa ndi zongowonjezwdwa, mwina mukudziwa kuti mitengo yamphepo ndi matekinoloje adzuwa yatsika kwambiri m'zaka zaposachedwa.
Pali mafunso angapo omwe eni nyumba omwe akuganiza zopita ku solar nthawi zambiri amakhala nawo.Yoyamba ndi yakuti: Kodi mphamvu ya dzuwa ikutsika mtengo?Ndipo zina ndi izi: Ngati dzuwa likutsika mtengo, ndidikire ndisanayike ma solar panyumba yanga?
Mtengo wa mapanelo adzuwa, ma inverter, ndi mabatire a lithiamu watsika mtengo pazaka 10 zapitazi.Mitengo ikuyembekezeka kupitilirabe kutsika - makamaka, mitengo ya solar ikuyembekezeka kutsika mtengo mpaka chaka cha 2050.
Komabe, mtengo wa kukhazikitsa kwa solar sudzatsika pamlingo womwewo chifukwa mtengo wa hardware ndi wochepera 40% wa mtengo wamtengo wopangira solar solar.Osayembekezera kuti solar yakunyumba idzakhala yotsika mtengo kwambiri mtsogolo.M'malo mwake, mtengo wanu ukhoza kukwera pamene kubwezeredwa kwanuko ndi aboma kumatha nthawi.
Ngati mukuganiza zowonjezera solar kunyumba kwanu, kudikirira mwina sikungakupulumutseni ndalama.Ikani ma solar anu tsopano, makamaka chifukwa ndalama zamisonkho zimatha.
Kodi kuyika ma solar panyumba ndi ndalama zingati?
Pali zinthu zambiri zomwe zimatengera mtengo wamagetsi opangira dzuwa kunyumba, ndipo zosankha zambiri zomwe mungapange zomwe zimakhudza mtengo womaliza womwe mumalipira.Komabe, ndizothandiza kudziwa zomwe zikuchitika m'makampani.
Mtengo poyerekeza ndi zaka 20 kapena 10 zapitazo ndi wochititsa chidwi, koma kutsika kwaposachedwa kwamitengo sikuli kwakukulu kwambiri.Izi zikutanthauza kuti mutha kuyembekezera kuti mtengo wa solar upitirire kutsika, koma musayembekezere kupulumutsa kwakukulu.
Kodi mitengo yamagetsi adzuwa yatsika bwanji?
Mtengo wa ma solar watsika ndi ndalama zosaneneka.Kalelo mu 1977, mtengo wa ma cell a solar photovoltaic anali $77 pa watt imodzi yokha ya mphamvu.Lero?Mutha kupeza ma cell a solar otsika mtengo ngati $0.13 pa watt, kapena kuchepera nthawi 600.Mtengowu nthawi zambiri umakhala wotsatira Lamulo la Swanson, lomwe limati mtengo wadzuwa umatsika ndi 20% pakuwirikiza kulikonse kwazinthu zomwe zimatumizidwa.
Ubale uwu pakati pa kuchuluka kwa zinthu zopangira ndi mtengo ndiwofunika kwambiri, chifukwa monga muwona, chuma chapadziko lonse lapansi chikuyenda mwachangu kupita ku mphamvu zowonjezera.
Zaka 20 zapitazi zakhala nthawi yakukula kodabwitsa kwa ma solar ogawidwa.Dzuwa logawidwa limatanthawuza machitidwe ang'onoang'ono omwe sali mbali ya magetsi opangira magetsi - mwa kuyankhula kwina, machitidwe a padenga ndi kumbuyo kwa nyumba ndi malonda m'dziko lonselo.
Panali msika wocheperako mu 2010, ndipo waphulika zaka kuchokera pamenepo.Ngakhale kunali kutsika mu 2017, kukula kwa 2018 ndi koyambirira kwa 2019 kukupitilirabe.
Lamulo la Swanson limafotokoza momwe kukula kwakukuluku kwadzetseranso kutsika kwakukulu kwamitengo: mtengo wa module ya solar watsika ndi 89% kuyambira 2010.
Mtengo wa Hardware motsutsana ndi zofewa
Mukamaganizira za solar system, mutha kuganiza kuti ndi zida zomwe zimapanga ndalama zambiri: ma racking, ma waya, ma inverters, komanso ma solar panel okha.
M'malo mwake, ma hardware amawerengera 36% yokha ya mtengo wamagetsi oyendera dzuwa.Zina zonse zimatengedwa ndi ndalama zofewa, zomwe ndi ndalama zina zomwe woyikira dzuŵa ayenera kunyamula.Izi zikuphatikiza chilichonse kuyambira pa ntchito yoyika ndi kulola, kukagula makasitomala (mwachitsanzo, kugulitsa ndi kutsatsa), mpaka pamutu wamba (mwachitsanzo, kuyatsa magetsi).
Mudzaonanso kuti ndalama zofewa zimakhala zochepa peresenti ya ndalama za dongosolo pamene kukula kwa dongosolo kumawonjezeka.Izi ndizowona makamaka mukachoka kunyumba kupita kuzinthu zofunikira, koma nyumba zazikuluzikulu nthawi zambiri zimakhala zotsika mtengo pa-watt kuposa makina ang'onoang'ono.Izi zili choncho chifukwa ndalama zambiri, monga kulola ndi kupeza makasitomala, ndizokhazikika ndipo sizimasiyana (kapena ayi) ndi kukula kwa dongosolo.
Kodi solar idzakula bwanji padziko lonse lapansi?
United States kwenikweni si msika waukulu kwambiri padziko lonse lapansi wa solar.China ikuposa US kutali, ndikuyika solar pafupifupi kawiri kuchuluka kwa US.China, monga mayiko ambiri aku US, ili ndi chandamale champhamvu zongowonjezwdwa.Iwo akufuna 20% mphamvu zongowonjezwdwa pofika chaka cha 2030. Ndiko kusintha kwakukulu kwa dziko lomwe limagwiritsa ntchito malasha kuti likhale ndi mphamvu pakukula kwa mafakitale ake.
Pofika chaka cha 2050, 69% ya magetsi padziko lonse lapansi adzakhala ongowonjezedwanso.
Mu 2019, magetsi adzuwa amapereka 2% yokha ya mphamvu zapadziko lonse lapansi, koma adzakula mpaka 22% pofika 2050.
Mabatire akulu, amtundu wa grid adzakhala chothandizira kwambiri pakukula uku.Mabatire adzakhala otsika mtengo ndi 64% pofika chaka cha 2040, ndipo dziko lidzakhala litayika 359 GW yamphamvu ya batri pofika 2050.
Kuchulukitsa kwa ndalama zoyendera dzuwa kudzagunda $4.2 thililiyoni pofika 2050.
Nthawi yomweyo, kugwiritsidwa ntchito kwa malasha kudzatsika ndi theka padziko lonse lapansi, mpaka 12% ya mphamvu zonse zomwe zimaperekedwa.
Ndalama zoikamo dzuwa zasiya kutsika, koma anthu akupeza zida zabwinoko
Lipoti laposachedwa kwambiri lochokera ku Berkeley Lab likuwonetsa kuti mtengo wokhazikika wanyumba zoyendera dzuwa watsika m'zaka zingapo zapitazi.M'malo mwake, mu 2019, mtengo wapakatikati udakwera pafupifupi $0.10.
Pamaso pake, izi zitha kuwoneka ngati dzuwa layamba kukhala lokwera mtengo kwambiri.Sizinatero: ndalama zikupitilira kutsika chaka chilichonse.M'malo mwake, zomwe zachitika ndikuti makasitomala akunyumba akukhazikitsa zida zabwinoko, ndikupeza phindu lochulukirapo pandalama zomwezo.
Mwachitsanzo, mu 2018, 74% yamakasitomala okhalamo amasankha ma inverter ang'onoang'ono kapena makina opangira magetsi opangira magetsi pazingwe zotsika mtengo.Mu 2019, chiwerengerochi chidakwera kwambiri mpaka 87%.
Momwemonso, mu 2018, eni nyumba wamba anali kuyika mapanelo adzuwa ndi 18.8%, koma mu 2019 mphamvu idakwera mpaka 19.4%.
Chifukwa chake ngakhale mtengo wa invoice womwe eni nyumba akulipirira sola masiku ano ndi wathyathyathya kapena akuwonjezeka pang'ono, akupeza zida zabwinoko ndindalama zomwezo.
Kodi mudikire kuti solar ikhale yotsika mtengo?
Makamaka chifukwa cha kuuma kwa mtengo wofewa, ngati mukuganiza ngati muyenera kudikirira kuti mitengo ichepe kwambiri, tikupangira kuti musadikire.36% yokha ya mtengo wa kukhazikitsa kwa dzuwa panyumba ndi yokhudzana ndi mtengo wa Hardware, kotero kudikirira zaka zingapo sikungabweretse kutsika kwamitengo komwe tidawonapo m'mbuyomu.Zipangizo zamagetsi zamagetsi ndizotsika mtengo kale.
Masiku ano, mphepo kapena PV ndizotsika mtengo kwambiri za magetsi m'mayiko omwe amapanga 73% ya GDP yapadziko lonse.Ndipo pamene mitengo ikupitilira kutsika, tikuyembekeza kuti mphepo yomanganso yatsopano ndi PV ikhale yotsika mtengo kuposa kuyendetsa magetsi opangira mafuta.
