Chiziviso chaTesla chezhizha chekuvaka bhatiri rakakura kwazvo rekuchengetedza bhatiri pasi rose muSouth Australia yaizivikanwa nekuchengeta akakosha ruzivo pasi pekuputira.
Neraki, nepo purojekiti ichiramba yakafukidzwa nechakavanzika, rumwe ruzivo nezve kuiswa kweTesla solar panels uye mabhatiri paHawaiian chitsuwa cheKauai, iyo yakaonekwa online pakutanga kwegore rino, inogona kuwanikwa kana kutorwa.
Muchokwadi, ikozvino kune ruzivo rwakakwana - maererano naElon Musk - kuita masvomhu.Izvi zvakafanana zvinoenda kune anokurudzira masvomhu.
Kunyangwe zvakakosha kuti mhinduro yaTesla yakachipa pane dhiziri, zvakatonyanya kukosha kuti yakachipa kunyangwe uchingoshandisa zvikamu zviviri muzvitatu zvesimba resolar panel uye zvikamu zviviri muzvitatu zvebhatiri chaiyo.
Tesla's Kauai project inosanganisira 55,000 solar panels inokwanisa kupa 17 megawatts epamusoro DC simba uye 52 megawatt-maawa ekuchengetedza lithium-ion bhatiri muchimiro che272 Powerpack 2s panzvimbo ye44-acre.
Yakati kurei zvishoma kupfuura Buckingham Palace (40 acres) uye zvishoma zvishoma pane hafu yehukuru hweVatican (110 acres).
Ziva kuti kunyangwe iyo solar array inowanzonzi 13 MW (AC yakavakirwa), iyo Kauai Island Community Cooperative inosimbisa nhamba yacho se17 MW (DC yakavakirwa).
Tesla akaita chibvumirano neKauai Island Utility Cooperative kuti ape grid neanosvika 52 megawatt-maawa emagetsi manheru ega ega.Sangano iri rakabvuma kubhadhara mwero wakafuratira we13.9 cents/kWh pachiedza chezuva chakachengetwa, chingangoita gumi kubva muzana pane chavanobhadhara kumagetsi edhiziri.
(Chitsuwa ichi chichiri kuda kupisa dhiziri munguva dzemagetsi makuru-kwete zvakanyanya. Uyezve, kunyange Hawaii inona makore nekunaya dzimwe nguva.)
Nekuda kwekuti sei Tesla asingakwanisi kutengesa magetsi zvakananga kune grid masikati, grid yeKauai haigoni kutora simba rakawanda rezuva: masikati, photovoltaics yatosangana nepamusoro pe90 muzana yezvido zvechitsuwa.
Pawebhusaiti yeTesla, Powerpack 2 yega yega yakayerwa pa210 kWh uye inoumbwa ne16 Powerwall 2s, iyo pachayo yakayerwa pa13.2 kWh.Izvi zvine musoro nekuti 13.2 kWh x 16 = 211.2 kWh.
Nekudaro, iyo yakakwana simba yemukati yega yega Powerwall 2 ndeyechokwadi yakakwirira.Yakatemerwa pa7 kWh, chizvarwa chekutanga Powerwall ibhatiri re10 kWh rakarongerwa kutenderera kusvika 70 muzana yekuburitsa simba, sekureva kweNational Renewable Energy Laboratory.
Izvi zvakafanana nekudzika kwezvikamu zviviri muzvitatu zvekuyerera kunoshandiswa muChevrolet Volt plug-in hybrid, iyo inoshandisawo nickel-manganese-chromium bhatiri chemistry.
Nekudzika kwekubuda kwezvikamu zviviri muzvitatu, iyo 210 kWh simba rekubuda rakapihwa nePowerpack 2 inoreva simba rakakwana re320 kWh.Saka, kukwana kwakakwana kwe272 Powerpack 2 paKauai i87 MWh.
Kubva pakatanga chiziviso chekuchengetedza simba muna 2015, Elon Musk akavimbisa mutengo webhatiri we $ 250 / kWh wekutumira kukuru uye akasimbisa iyo nhamba pamberi peprojekiti ichangoburwa muSouth Australia.
Mutengo we $250/kWh wesimba rezita pachikamu chemodule inova yakaderera zvakanyanya simba re $170/kWh apo zvikamu zviviri kubva muzvitatu zvekudzika kwekubuda zvinofungwa.
Nei Tesla ichinyora simba rezita re57 MWh uye inongoshuma 52 MWh?Mabhatiri ekuwedzera anogona kupa chirimwa paKauai chinogona kugadzira 52 megawatt-maawa emagetsi pazuva, kunyangwe mushure memakore makumi maviri ekupfeka kwebhatiri.
Solar panels akaiswa muKauai anogadzikwa tilt, zvinoreva kuti akaiswa pakona yakatarwa;haatenderere masikati, achitevera zuva sezvimwe zvivako zvakakura zvezuva.
Sekureva kwaLawrence Berkeley National Laboratory, mapurojekiti matatu ezuva aKauai aripo anga achimhanya kwerinopfuura gore, achiwana masimba e20%, 21% uye 22%.(Simba chinhu chiyero chesimba rinogadzirwa negwenya remagetsi kune iro rinonyanya kufungidzira simba.)
Izvi zvinoratidza kuti simba re 21% fungidziro inonzwisisika yekugadzirwa kwe photovoltaic muTesla's Kauai project.Saka, kuwedzera 17 megawatts ne 21% simba mumaawa makumi maviri nemana kunotipa 86 megawatt-maawa emagetsi pazuva.
Zvichienderana nemaitiro echigadzirwa, magetsi emagetsi anogona kushandura DC kupinza kuita AC inobuda nekugona kunosvika 90%.Izvi zvinoreva kuti 86 MWh DC yakatarisana nezuva inofanira kuburitsa 77 MWh AC yakatarisana negridi.
Iwo anosvika makumi mashanu nemaviri megawatt-maawa ayo Tesla anovimbisa kutengesa manheru ega ega angangoita maviri muzvitatu e77 megawatt-maawa ayo Tesla anotarisira kubva kune ayo solar panels zuva rega rega.
Zvichitaurwa zviri nyore, ese ese solar uye bhatiri maseru akawandisa, asi kunyangwe zvakadaro, hupfumi hunoramba huchishanda.
Nepo Tesla ichikwanisa kupa anosvika 52 megawatt-maawa emagetsi kuKauai grid zuva rega rega, haigone kuzviita mumazuva ane dutu kana kunaya.
Kuti uongorore izvi zvinokonzeresa, Yakachena Power Research's SolarAnywhere software yakagadzira inomiririra gore negore solar irradiance data yeLihue, Kauai, uko Tesla chirongwa chiripo.
Kuti zvive pachena, iyo data yakashandiswa mukuongororwa uku inogona kutariswa patinyurl.com/TeslaKauai.
Gore rinomiririra reSolarAnywhere data rinoratidza avhareji yepasi rose yakatwasuka kuratidzwa kwemaawa 5.0 pazuva, inoenderana nechikamu chesimba che21%.Izvi zvinoenderana nedata kubva kuLawrence Berkeley National Laboratory.
SolarAnywhere data inofanotaura kuti mugore rayo rekutanga, Tesla ichapa avhareji ye50 megawatt-maawa emagetsi pazuva kuKauai's utility cooperatives.
Iine imwezve 5 MWh yebhatiri, kunyangwe mushure mekuderedzwa negumi muzana mu solar panel uye huwandu hwebhatiri, Tesla inofungidzirwa kuti iri kupa pakati pe45 ne49 MWh yemagetsi pazuva kune grid (zvichienderana neyakajeka yemaitiro ayo ekushandisa)..
Tichifunga kuti avhareji yemazuva ese mupiro kune grid inodonha kubva pa50 MWh kusvika 48 MWh mumakore makumi maviri anotevera, Tesla ichapa avhareji ye49 MWh pazuva.
Green Tech Media inofungidzira kuti purazi rezuva rekushandisa richaita madhora 1 pawatt panguva yekuiswa paKauai, zvichireva kuti chikamu chezuva chepurojekiti paKauai chichadhura madhora gumi nemanomwe emadhora.Nekuda kwechikamu che30 muzana chechikwereti chemutero, izvi zvakaunza mari inosvika madhora gumi nemaviri.
Ongororo yeEPRI/Sandia National Laboratories yakaitwa muna Zvita 2015 yakafungidzira kuti mari yekushandisa nekuchengetedza mapurazi ezuva rekushandisa inosvika pakati pemadhora gumi nemadhora makumi maviri neshanu pakilowati pagore.Uchishandisa iyo madhora makumi maviri neshanu, iyo inodaidzwa kuti O&M inodhura yegumi nenomwe MW solar panel pane saiti ingangoita $425,000 pagore.
Chibodzwa chepamusoro chakakodzera nekuti chirongwa cheTesla Kauai chinosanganisira bhatiri paki pamwe nemapaneru pachawo.
Pa $250 pakilowatt awa, mabhatiri eKauai anodhura madhora gumi nematatu emamiriyoni.Tesla anowanzo kuyera wiring uye midziyo yekutsigira munda zvakasiyana, iyo inogona kunge yakakwira semadhora mazana mashanu.
Mushure mekusarudza yakaipisisa O&M mutengo, isu tichatora yakanakisa tambo uye mutengo wemidziyo uye tofunga kuti ndeyemahara.
Pakazara, Tesla ichange iine madhora mazana maviri neshanu emamiriyoni emadhora pagore mumari inosvika zviuru makumi maviri nematanhatu emadhora mumitengo yepamberi (madhora gumi nemaviri epurazi rezuva, madhora gumi nemaviri emadhora emabhatiri) uye angangoita madhora mazana mana nemakumi maviri neshanu pagore mumutengo.
Pasi pemafungiro aya, chiyero chemukati chekudzoka kweTesla Kauai project ndeye 6.2%.
Kunyange izvi zvakaderera zvisingagamuchirwi kumaindasitiri mazhinji, SolarCity, senge yakawanda yeindasitiri yezuva, inoshandisa yakaderedzwa mari yekubuda kwe6%, uye Kauai pakutanga yaive SolarCity chirongwa.(Tarisa kune spreadsheet rakabatanidzwa pamusoro zvakare kuti uwane ruzivo.)
Izvi zvinoratidza kuti nhamba dzakarurama;tinogona kufunga kuti zvikanganiso mukufungidzira kwakasiyana zvinogona kukanzura mumwe nemumwe kunze.
Kwenguva yakawanda yegore, chirongwa cheTesla paKauai chinogadzira magetsi akawanda kupfuura mabhatiri ayo anogona kubata.Zvakafanana zvinoenda kumapurojekiti emangwana.kuita sei?
Imwe sarudzo ndeye kushandisa magetsi akawandisa kuparadzanisa mvura uye kugadzira hydrogen yemafuta emotokari;Hawaii yekutanga mafuta cell hydrogenation station inoshandisa nzira iyi paOahu.
Kana Tesla's Kauai project inogona kutengesa mamwe e20 kana kupfuura megawatt-awa inogona kupedza zuva nezuva pakuisa simba rehydrogen electrolyzers, iyo yemukati yepurojekiti yekudzoka ichakwira zvakanyanya, kunyangwe iwo magetsi akapihwa nemutengo wakaderera.
Izvi zvingagadzira chiitiko chinokatyamadza icho chiri mukufarira kwaTesla kutarisira kuti budiriro yehydrogen mafuta emotokari inogadzira kudiwa kwehydrogen.
Chidzidzo chisingatarisirwi kubva kuTesla's Kauai purojekiti inogona kunge isiri iyo chete masero emafuta asingatadzisi shanduko yedu kune inovandudzwa kana zero-emission simba, asi vanogona kuita basa kana hydrogen yavanoshandisa ikagadzirwa chete vachishandisa simba rinogoneka.simba.
Chidzidzo chikuru, zvisinei, ndechekuti Tesla yakaratidza kuti kusanganisa solar panel uye kuchengetedza kwesimba kunoita kuti hupfumi hunzwisise kwete mune ramangwana, asi nhasi.
