Itanani kuti Mkangano Waukulu.Tekinoloje yatsopano ikhoza kusokoneza mbiri yakale ya makampani a madola triliyoni.Kuphatikizika kwa kusungirako batri ndi mphamvu ya dzuwa kukuyembekezeka kukhala ndi zotsatira zomwezo pamakampani amagetsi monga momwe intaneti inachitira ndi zofalitsa ndi mafoni a m'manja kupita ku mafoni a m'manja.
Palibe kwenikweni kutsutsana kwakukulu pa izi.Izo zimavomerezedwa ndi ogula, opanga teknoloji, ogulitsa, ogulitsa maukonde ndi magetsi opangira magetsi.Ngakhale ndale amachita izo.Mtsutso waukulu ndi wakuti izi zidzachitika liti komanso mofulumira bwanji.Ena amati tsopano ndi posachedwa. , ena sadziwa kwenikweni.
Poyesera kusiyanitsa izi ndikuwonetsa malingaliro osiyanasiyana momwe angathere, RenewEconomy idzafalitsa mndandanda wa zolemba zomwe zikuwunika kuyerekezera kosiyanasiyana.
Timayamba lero ndi banki ya ndalama UBS.Mmodzi mwa makhalidwe a kusintha kwa mphamvuyi ndi kukhudzidwa kwapafupi ndi kuyang'anitsitsa gulu la ndalama zogulitsa ndalama.Amakhulupirira kuti izi sizomwe zimapangidwira.Izi ndizo maziko omwe amawunika kuopsa kwa ndalama zopangira mphamvu. mu mazana a mabiliyoni, kapena mabiliyoni kapena madola, kuzungulira dziko lapansi.
Lipoti la UBS pa chuma cha Tesla Powerwall chimachokera kwa akatswiri awo a ku Australia.Izi sizosadabwitsa chifukwa mtengo wamagetsi ku Australia ndi kulowetsedwa kwakukulu kwa dzuwa kudzathandiza zero kusungirako batire padziko lonse lapansi.Chodabwitsa, mankhwalawa sadzakhalapo mpaka chaka chamawa, ngakhale kuti ena mwa Tesla ochita nawo mpikisano angayesere kuyambitsa ndi kuyambitsa kwawo kwazinthu zawo.
Chomaliza chachikulu cha gulu la UBS ndikuti mtundu wa 7kWh wa Tesla Powerwall udzalipira ndalama.Amayesa IRR (ndalama yamkati yobwerera) kukhala 9%.Izi zikutanthauza pafupifupi zaka zisanu ndi chimodzi zobwezera.Ngati akulondola, zikutanthawuza kuti kukhazikitsidwa kwa misika yayikulu sikuli kutali monga momwe ena amaganizira, ndipo mabungwe omwe ali nawo angayembekezere.
Mtengo ndi chinthu chofunikira mu equation.UBS ikunena kuti pali mkangano waukulu pa kusiyana pakati pa mitengo ya batri ($ 3,000) ndi zopereka zoyika (pafupifupi $7,000).
Koma inanena kuti ngakhale kuti zikhoza kukhala choncho ku US, kumene padenga PV ndi okwera mtengo kwambiri kukhazikitsa kuposa Australia, amakhulupirira kuti kusiyana pakati pa mitengo selo ndi unsembe mitengo sadzakhala mkulu mu Australia.
Kuwunikaku kumaganiziranso kuti batire imatha kugwiritsa ntchito mphamvu zonse za 7KWh tsiku lililonse, komanso kuti solar system ndi yayikulu mokwanira kuyitanitsa batire ndikupereka mphamvu kumbuyo kwa mita. Madola aku Australia ndipo adzakhala mitengo yaku Australia.
Ofufuza a UBS adanena kuti ali ndi chidaliro kuti angapeze ma inverters pafupifupi $ 1,100. Anagwiritsa ntchito chitsanzo cha 'Powador' mu chitsanzo, chomwe chimagulitsidwa $ 1025. Mtengo woyika ndi $ 5,175.
Ponena za momwe zimagwirizanirana ndi msika, UBS imatchula mtengo wamagetsi wamtengo wapatali wa $ 0.51 kWh m'chigawo cha gridi ya Australia ndi mtengo woperekedwa kugulitsa magetsi ku gridi ya $ 0.06 / kWh.
Imaganiza kuti dongosololi ndi lothandiza 89% komanso kuti ntchito yoyika ndi maola 4 pa $ 100 pa ola limodzi.
"Pazifukwa izi, tidawona kuti, kunyalanyaza misonkho, dongosololi litha kupereka ndalama zobwezera 11 peresenti, kuposa chiwongola dzanja cha ngongole yanyumba komanso nthawi yobwezera yazaka zisanu ndi chimodzi."Inanenanso kuti mabatire ndi omwe akuyenera kugwiritsidwa ntchito Nyumba zazikulu zotsekeka zomwe zili ndi magetsi opitilira muyeso komanso solar solar wamkulu kuposa avareji.
Tsopano, ena angapeze kuti mtengo wa UBS ndi wodalirika. Koma ngakhale mtengo wa ogwira ntchito ndi mtengo wamtengo wapatali ukanakhala wokwera kwambiri ndikukankhira ndalama zonse zoyikirapo mpaka $6,300, ogula omwe anali ndi makina oyendera dzuwa adzalandirabe IRR yofanana ndi yawo. ngongole yanyumba.
(Onaninso nkhani yamtsogolo yomwe Morgan Stanley amawona mabanja aku Australia okwana 2.4 miliyoni ali ndi malo osungira mabatire, omwe amaphatikizanso kulosera kwazaka 6 zobwezera kumayiko ena).

Inde, ku mbali yowala osati kafukufuku wabwino kwambiri wa UBS… Tiyerekeze kusiyana pakati pa 51c ndi 6c…chifukwa mukutenga zinthu ziwiri zoyembekezeka kwambiri, mtengo wamagetsi mumgwirizanowu ndi pafupifupi theka la 51c zomwe zatchulidwa pano komanso kuchokera. kuposa zogulitsa kunja kwa 6c.Ndiko kuti, pamene mitengo yamalonda imakhala yokwera kuposa mitengo yamtengo wapatali, ndibwino kuti muzigwiritsa ntchito nokha, kotero kuwonjezera zosungirako panthawizi sikukuwonjezera phindu.Kusungirako ndi lingaliro labwino, koma zachuma sizowoneka bwino monga momwe ziwerengerozi zimayambira…
Warwick, ziwerengerozi zingawoneke ngati zolimba, koma ndichifukwa chakuti tsopano Tesla Powerwall yatulutsidwa, mtengo wa batri ukutsika mofulumira, kotero kuti chuma chimakhala chokongola kwambiri.Ngati chirichonse UBS chiri chosungira. -mitengo-kutsika-ngakhale-mwachangu-monga-magetsi-kugulitsa-galimoto-kupitilira-kukwera-39780
Conservative?Kumeneko ndiko kutambasula.Zolingalira ndiye vuto.Ndinapeza malingaliro atatu kapena anayi kukhala ocheperako kuposa osunga.
Ndine kasitomala wabwino.Sindigulitsidwa.Mukudziwa, ngati kukula kwake sikukugwirizana ndi zomwe mumapanga ndikugwiritsa ntchito pafupifupi nthawi zonse, manambala amenewo adzagwa mwachangu.Ngakhale kuvomereza kuti palibe dongosolo lomwe liri loyenera, funso limakhala. : chifukwa chiyani ndikufuna batire la mphamvu x + y pamene ndikungofuna x?
Zikomo Warwick.Ndikukuuzani, ngakhale ku Japan, sindingathe kupeza manambala kuti ndigwire ntchito, choncho ndakhala ndikuyendayenda pa intaneti kuti ndiwone zomwe anthu akuchita. Zikomo kwa anthu omwe ali pa webusaitiyi omwe adatenga nthawi kuchita masamu.Izi ndizosowa kwambiri.
Ndikuyembekeza zowonjezera zaka zingapo FIT ya ku Japan itatha, koma sindikudziwa kuti ndalama zina ndi zikhalidwe zidzatani panthawiyo. , ndalamazo sizidzabwezanso zoyembekezeredwa.
Kumbukirani zochitika zina.Ngati mumapanga 15 kW masana, ndikukhala ndi gulu lotsalira, ndipo mumadya mphamvu zambiri za gridi dzuwa litalowa, dongosolo la batri lingakhale lothandiza ngakhale mtengo wogulitsa uli wapamwamba kuposa FIT. Komanso kumbukirani kuti anthu ambiri amapanga machitidwe awo kuti apititse patsogolo mphamvu zamagetsi, osati kuti agwirizane ndi zomwe amagwiritsa ntchito. kubweza pa storage.Choncho pokhapokha mutakhala ndi solar yaulere (palibe FIT) komanso mitengo yokwera kwambiri ya gridi, izi sizilipira.
Rockne, ndizosangalatsa kukuwonani mukuzindikira kuti kutsutsa kwanga kwa positiyi ndikokhudza kupeza manambala molondola osati kutsutsana ndi teknoloji (yomwe ndikuganiza kuti ili ndi mphamvu zambiri) .Mwina njira yosavuta yofotokozera mtengo wosungidwa ndi mwayi awiri omwe amapereka: 1) Kusintha mphamvu zogwiritsira ntchito mphamvu kuchokera pamtengo wokwera kwambiri wa gridi kupita kunthawi zosakwera kwambiri pomwe mitengo imasiyana kwambiri 2) sungani mphamvu zochulukirapo za PV ngati zitagwiritsidwa ntchito pagululi, ndiye kuti mtengo wogwiritsa ntchito pambuyo pake ndi wokwera kuposa mtengo woperekera chakudya choperekedwa ndi kutumiza kunja. .
Sindikutsimikiza ngati lipoti la UBS lidachitidwa ndi ena omwe amaphunzira ntchito kapena mwina zomwe zidasankhidwa mwadala kuti chumacho chiwonekere kukhala chokongola kwambiri chifukwa zikuwoneka ngati amasankha zinthu zoyendetsedwa bwino (mwachitsanzo, madzi otentha osakwera kwambiri. ) Mitengo ya PM ili pafupi ndi 51c kuyambira 2pm mpaka 8am ndi kuzungulira 11c kuchokera pachimake (10pm mpaka 7am). Ndizomveka kuti PV yokha imatha kupanga pachimake ndikuchotsa kugwiritsa ntchito kuthamangitsa kwambiri, koma bwanji mungavutike kusunga mphamvu za PV zochulukirapo panthawi ya tsiku (ie mukhoza kuchepetsa 11c pafupifupi 20c / kWh kapena off-peak) ndi FiT 6c, kotero Kupindula pambuyo pa kutaya ndi 5 kwa 15c / kWh. kunyalanyaza PV kwathunthu (ngati mugwiritsa ntchito mphamvu yayikulu kwambiri) ndikuyitanitsa pa 10c/kWh nthawi yomwe simunagwirepo m'malo mwa 51c/kWh yamphamvu kwambiri kWh, motero mukutaya Sungani 41c/kWh m'mbuyomu…
Ayenera kuyeretsa kusanthula kwawo ndi kulongosola mwatsatanetsatane zomwe akuganiza kuti anthu athe kuwona kufunika kwake.Kusungirako kukubwera, koma osati mofulumira monga momwe kafukufukuyu akusonyezera ...
Ndinenso "chifaniziro chazithunzi". Ndine wokonzeka kugula kapena kusagula kutengera manambala, osati gee whiz factor.
Ndime yonse yoyamba. Ndipo ndilinso ndi mitengo yotsika kwambiri, ndiye kuti ndilingalira malingaliro onse awiri. Ndakhala ndikuganiza za "vuto" ili kwa zaka zambiri.
Monga mfundo yochititsa chidwi kwa inu, zambiri zowunikira pa intaneti zikuwala, koma zikuchitidwa ndi Morgan Stanley, kasitomala wamkulu wa Tesla ndi wobwereketsa. kusamala ndi kuyerekezera.
Pankhani ya ndime yanu yachiwiri, mukuwoneka kuti mukuwona kuti anthu a ku UBS samasiyanitsa pakati pa mfundo ziwiri zofunika. mphamvu ya dzuwa kuti ithetse kufunika kwa magetsi mpaka 10pm. Kwa ine izi ndizofunikira chifukwa 10 kWh iyenera kukhala yokwanira kuphimba izo.Pansi pamikhalidwe yabwino kwambiri, 10 kWh ingandipatse $ 3 patsiku.M'dziko lenileni, ndizofanana ndi 2.2.Kwa iwo omwe ali ndi kusiyana kwakukulu pakati pa chiwongoladzanja ndi kutsika, palinso phindu la kuchulukitsa kusiyana pakati pa mlingo ndi mphamvu ya batri.Pansi pazikhalidwe zabwino, batire ya 10 kWh ingandiyendetse pafupifupi $ 2 patsiku. , ingakhale 1.5.Mwinanso mocheperapo, chifukwa monga masana, sindingathe kuthimitsa batire kapena kulichangitsanso masana!Ha ha.
Ngati mutha kugwiritsa ntchito zonse 1 ndi 2 pamwambapa, muyenera kusamala kuti mumayenda kawiri pa tsiku ndipo batire mudzatha zaka 6!
Kotero ife tinafika pa lingaliro lomwelo.Mabatire oterowo angawoneke ngati lingaliro labwino kwa ena, koma kwa ndani?Elon Musk mwachiwonekere, koma ayi?
Kuonjezera apo, dongosololi "liyenera" kutulutsa batri kwakanthawi masana kuti athetse ma spikes oitanitsa, onse aifupi ndi aatali.Kutumiza kumayambanso, pakatha mphindi zingapo kapena maola angapo, batire idzachira polipira. sindikudziwa kuti "kuyenda pang'onopang'ono" kumakhudza moyo wa batri.
Ah!Nyongolotsi zam'zitini zochulukirachulukira! Ndiye kodi izi sizinthu zomwe munthu amaziwongolera pogwiritsa ntchito zowerengera nthawi komanso masiwichi?
Ndinapeza ndemanga chidwi kwambiri.Palibe, koma palibe amene angavutike kuganizira kwenikweni za njinga, ndalama ndi mapangano nawo.
Kupeza "phindu" kumbali ina ya maze sikophweka.Ndikukhulupirira kuti anthu ambiri amangoponya ndalama patebulo ndikudalira Mulungu.Ndikukhudzidwa kuti izi zikhoza kutulutsa zotsatira zomwe zikuyembekezeka.
Kungofotokozera zinthu zingapo za positi iyi.Ndili 100% kumbuyo pa kusungirako batri, chitsanzo cha Tesla ndi chinthu chaching'ono kwambiri chifukwa anthu akufuna kusunga ndalama zochepa pamagetsi awo amagetsi. , ndipo zikafika ku OFFGRID Faith, mtengo wake ndi $ 3500 okha. Kuchokera pazomwe ndawerengapo, dongosololi liri ndi mphamvu yaikulu ya 2000w, m'moyo weniweni ndiyo mphamvu yomwe imagwiritsidwa ntchito kuphimba 1 air conditioner kapena 1 ketulo yamagetsi. , kuunikira kwanu kwa nyumba yausiku ndi firiji ikuyenda, koma china Chilichonse chidzafunika kuchokera ku grid.Oven, mbale yotentha idzakhala grid.Nkhaniyi imatchulanso Powador inverter, yomwe ndi inverter yomangidwa ndi grid, osati inverter yosakanizidwa, kotero izo alibe mphamvu zolipiritsa batire, ndipo ndapeza kuti ma inverters ambiri osakanizidwa amagulitsa pafupifupi $ 2500. Ndauzidwanso kuti zida za ku Australia siziloledwa kulipiritsa dongosolo pamitengo yopanda malire, ziyenera kutero. mtengo kuchokera kumitengo ya solar kapena nsonga, ngati wina angakonze izi, ndingasangalalemverani. Izi nthawi zambiri zimatanthauza kuti ngati mphamvu ya 4kwh ya batri ikugwiritsidwa ntchito chifukwa cha kutayika bwino, zidzatengera 5kwh ya grid mphamvu kuti iwononge kachiwiri. zimakhala zotheka ngati mutha kulipira kuchokera ku solar ndikugula mphamvu yofunikira kuchokera ku gridi yomwe dongosolo silingathe kuphimba.Makina ambiri amafuna mphamvu yolemetsa ya osachepera 4000w, yomwe idakali yotsika kwambiri m'moyo weniweni.Zothandizira zimafunikira AS 4777 inverters ovomerezeka. Kutembenuza ma grids osakwana 6000w mumayendedwe aliwonse omwe aperekedwa. M'madera enieni a moyo, mabanja ambiri amatha kugunda izi nthawi iliyonse ya chakudya, izi ndi nthawi zomwe zimafunika kwambiri. : 3 x tesla 7kw @ $4850AUD kuti mupereke mphamvu yolemetsa ya 6000w 1 x Solar Edge @ $2500AUD solar panel @ $5000 kuyika @ $2000 Mtengo wonse $24,000 Izi ndi Palibe mtengo wazinthu zakomweko %. ndimakonda Tesla ndipo ndimadzigulira ndekha galimoto ndi Powerwall ndi carport carport charger chifukwa "simungakhalemwana wozizira kwambiri pa block” monga kukhala ndi Apple TV, Iphone, Makompyuta ali ngati matabuleti, amangogwira ntchito mosavutikira ndipo tiyeni tiyang'ane nazo, ndi abwino! Zikomo Tesla, mwagula iPhone yatsopano ya siteshoni yamagetsi ndipo mwagula kusungirako mphamvu padziko lonse lapansi.
Ili ndi chojambulira chomangidwira, chotchedwa DC/DC converter.Sichikhoza kulipiritsidwa kuchokera ku gridi, kokha kuchokera ku DC ndi solar.Imafika pachimake pa 3.3kW, kotero 3 ndi 9.9kW. Nkhaniyi ikunena za On Grid, osati Off Grid.
Kodi wina angalumikize mlatho/transfoma ya DC kuti azitchaja batire kuchokera pagululi?Mungopeza mphamvu pang'ono usiku kuchokera kumphepo yapafupi kuti mudzazitsenso batire?
Zikomo, awa ndi ndemanga yofikirika kwambiri, kwa ife owerenga "math for dummies".
Izi ndi zongoganiza zambiri.Ndinkaganiza kuti $3500 ikuyenera kukhala yogulitsa?Sindinamvepo chitsimikizo kuti Powerwall ilidi ndi charger/inverter yofunikira yamkati?Ngati ndi choncho,ndichifukwa chiyani mumatchula inverter yakunja?Ngati ilibe inverter ya charger mkati (monga mitundu ina idzachita / idzachita), ndiye ndikuganiza mtengo wa Kaco ndi mtengo "wolowa m'malo" wa charger / inverter yakunja, popeza Kaco mwiniwake sangakwaniritse Udindo uwu. Komanso, mtengo wa kukhazikitsa ukuwonjezeka ndi chiwerengero cha zigawo zakunja kuti "zilumikizidwe" monga momwe ziyenera kukhalira zolimba (za Australia) monga zotsekera ma voltage otsika. $ 400 poika, kuyendetsa chingwe, ndi zina zotero. kwenikweni kumbali yotsika, IMHO.
Tesla Powerwall ili ndi chosinthira chamkati cha DC / DC;iyi ndi charger.Powador imagwiritsidwa ntchito kutembenuza kukhala 240V.
Ponena za kulumikizana, solar to powerwall, powerwall to inverter, job done.Ili ndi kulumikizana kwa 1 kokha.
Bwanji mugule inverter ina yomangidwa ndi gridi ngati kasitomala ali kale ndi PV system?Pwall iyenera kuikidwa pamalo otetezedwa ku nyengo - izi zikhoza kuwonjezera mamita 10 a chingwe cha ngalande, komanso zodzipatula ndi zotsekera.
Chojambulira chophatikizika / inverter ndiyo njira yopitira, koma Pwall akadalibe zambiri, komanso mtengo womwe takambirana pano. .Ndichifukwa chake ndikunena kuti zambiri za Pwall zikusowa kapena sizikudziwika.
Chizoloŵezi cha Chris chophatikizira zinthu zina zamagetsi mu inverter ndizolakwika.Zowonadi, iyi ndi "mtengo wowonjezera" wosankha opanga ma inverter opangidwa ndi grid, koma njirayi ndi yotsutsana, ndipo pokhapokha ngati teknoloji yomangidwa ndi grid ili chete. wothandizana nawo omwe ali ndi udindo wotsimikizira kuti kasitomala akutumiza mosalekeza [gridi] zotheka pazovuta zilizonse.
Mapangidwe abwino kwambiri a inverter / converter amatsimikizira kuti amagwira ntchito imodzi yokha [kutembenuka] ndipo amachita bwino komanso mwamphamvu.Kukhalitsa ndi ntchito za nthawi yayitali ndizo ntchito zazikulu za otembenuza.Siziyenera kulemedwa ndi ntchito zozungulira.
Mwachitsanzo, taganizirani zochitika pamene chigawo cha inverter wothandizira module [charge controller kapena monitoring unit] chikulephera;inverter imapuwala ndikutseka chifukwa cha kulephera kwa gawo losafunikira.
Ma module othandizira mphamvu zamagetsi amasiyidwa bwino kwa opanga ukadaulo wa chipani chachitatu, omwe amatha kuphatikizidwa mu dongosololi pofunsidwa ndi wopanga dongosolo.Kuphatikiza apo, mpikisano pakati pa opanga chipani cha 3rd kumabweretsa kusintha kwaukadaulo;kuchuluka kwa mpikisano komanso kutsika mtengo.
Ndinagwiritsa ntchito mfundo zazikuluzikuluzi poyamba pamapangidwe athu kuti ndipange inverter yopanda grid ndipo zotsatira zake zimafotokoza nkhani.Opanga ma gridi ayenera kugwiritsa ntchito malingaliro omwewo.
