Kupanga kulumikizana: Moto & mphamvu zamagetsi zamagetsi

Zonena za Walmart kuti moto wina wamagetsi oyendera dzuwa padenga la masitolo ake zidayambika ndi zolumikizira zomwe zimadetsa nkhawa zomwe makampani akhala nazo kwakanthawi.Ndipo mavuto amaposa wopanga kapena woyikira m'modzi.

Inki yambiri yatayidwa pamilandu yomwe Walmart adapereka motsutsana ndi Tesla, yokhudzana ndi moto wamagalasi adzuwa pamadenga amasitolo ake.Koma atolankhani ochepa adafunsa chifukwa chomwe motowu udachitika poyambirira, makamaka ndi zolemba zaukadaulo zomwe zimafotokoza momveka bwino kuti zoyika bwino za solar siziyatsa moto.

Ndipo pomwepo pali chidziwitso choyamba - kuti mavuto sangakhale m'magulu okha, monga momwe adayikidwira.Kusaka mwachangu kwa "cholumikizira" kukuwonetsa kuti mawuwa amawoneka kangapo pamasamani omwe adaperekedwa ndi Walmart pa Ogasiti 20, 2019.

Sikuti Walmart amangonena kuti moto m'masitolo ku Milpitas ndi Lakeside, California unayambitsidwa ndi zolumikizira zolakwika, koma kampaniyo imanenanso kuti ogwira ntchito ku Tesla anali ndi zolumikizira zomwe sizimagwirizana, kuti alephera kulumikiza zolumikizira mokwanira, ndipo analephera kusintha zolumikizira zolakwika kapena kuyatsa bwino zoyendera zotsatirazi, zonse zomwe zidapangitsa kuti pasakhale chitetezo.

Monga momwe zawululira mu lipoti lotsatira la Business Insider, Tesla anali akuyendetsa pulogalamu yamkati kuti asinthe zolumikizira izi, zomwe zidadziwika kuti zolumikizira za Amphenol H4.Amphenol wakana kuti zolumikizira zake zinali ndi chochita ndi moto, koma nkhani zaposachedwa ndi diso lina lakuda kwa kampaniyo kutsatira kukumbukira kwa SolarWorld kwa ma modules pogwiritsa ntchito zolumikizira za Amphenol zaka ziwiri ndi theka zapitazo.

Komabe, kafukufuku wa magazini ya pv akuwonetsa kuti mavuto omwe ali ndi zolumikizira ndi kuyika kwawo ndi ozama kwambiri kuposa wopanga kapena woyika aliyense, komanso kuti zovuta zolumikizira zitha kukhala bomba lanthawi yayitali pamakampani oyendera dzuwa.

"Ndingakonde kunena kuti ndizochitika zokhazokha, koma ndizovuta kwambiri pamakampani," akutero Brian Mills, woyang'anira malonda - photovoltaics ya Stäubli, yomwe pansi pa dzina lakale la Multi-Contact inapereka zolumikizira pafupifupi pafupifupi. theka la solar pa intaneti padziko lonse lapansi.

Stäubli atchulapo njira yolephereka ndi zotsatira zake (FMEA) yopangidwa ndi EU-Solar Bankability Project, yomwe imazindikiritsa kugwiritsa ntchito mitundu yosiyanasiyana yolumikizira - mchitidwe womwe umadziwika kuti "intermating" - chifukwa chomwe chimayambitsa kulephera kwa gawo, ndi mitundu yosiyanasiyana ya zolumikizira zomwe zimazindikirika ngati zovuta zokwera mtengo kwambiri.

Kunena zomveka, izi sizikutanthauza kuti cholumikizira chilichonse chimathera padenga lamoto kapena munda.Koma zikuwonetsa kuti zolumikizira zakhala gwero lamavuto akulu.

Kuti mumvetsetse chifukwa chake izi zili choncho, mfundo zina zofunika zokhudzana ndi zolumikizira ziyenera kumveka.Wopanga zolumikizira aliyense amapanga zinthu zawo motsatira miyezo yake yamkati, ndipo pomwe zinthuzi zimatsimikiziridwa ndi UL kapena mabungwe ena, palibe mulingo umodzi wolumikizira monga momwe umakhalira wamapulagi amagetsi omwe amapita m'mabokosi apakhoma.

Ndipo kusiyana kwake sikwachiphamaso.Zolumikizira zimapangidwa ndi zinthu zambiri zosiyanasiyana, ndipo Mtsogoleri wamkulu wa Shoals Technologies Dean Solon akunena kuti ngakhale kuti zolumikizira zambiri zapamwamba zimakhala ndi zolumikizira zamkuwa, ena amapanga amagwiritsa ntchito bronze kapena aluminium alloys, ndipo akuti adawonapo zitsulo.

Kuonjezera apo, palibe muyezo umodzi wa kukula kapena kulolerana kwa zolumikizira, zomwe zikutanthauza kuti ngakhale zolumikizira ziwiri zochokera kwa opanga osiyanasiyana zimawoneka ngati zofanana kukula ndi mawonekedwe, kusiyana kosawoneka kungakhale kwenikweni - ndi kuwononga.

Brian Mills waku Stäubli akuti zolumikizira zolumikizirana ndikuphwanya malamulo a National Electrical Code (NEC), koma akuti sizinayimitse oyika ambiri kuchita izi.

"Takana makasitomala omwe amafuna kulumikizana," CEO wa Shoals Dean Solon adauza pv magazine."Timawauza kuti sitikufuna kutenga nawo mbali pamilandu."

Popeza kuti zolumikizira zolumikizirana zimaphwanya NEC komanso kuti zolumikizira zosiyanasiyana zochokera kwa opanga osiyanasiyana zimatha kukhala ndi kusiyana kowoneka bwino, mungaganize kuti opanga angafune kuwonekeratu kuti malonda awo sangathe kulumikizidwa ndi chinthu chochokera kwa wopanga wina.

Koma ndiko kuyiwala kufooka kwaumunthu kwaukali, ndi momwe izi zingakhalire zokonda zanthawi yayitali.Solon ndi Mills onse amazindikira kuti zolumikizira zambiri zimafotokozedwa ngati "MC-4 yogwirizana" pamasamba opanga ma module, zomwe zikuwonetsa kwa oyika kuti atha kulumikizidwa ndi Stäubli's MC-4.

Ndipo ngakhale mawu omveka bwino ochokera ku Stäubli akuti chitsimikizo chake chidzaphwanyidwa ngati zolumikizira zake zilumikizidwa ndi zinthu zochokera kwa ogulitsa ena, izi sizinayimitse chizindikiro cha "MC-4 chogwirizana".

Shoals akunena kuti opanga ma module akuyenera kuyang'aniridwa pano, komanso kuti akapereka phukusi lazinthu kuphatikizapo ma modules kwa makasitomala, zimafuna kuti ogulitsa alembe zolemba zonse, kuphatikizapo kutchula dzina la wopanga amene anapanga zolumikizira zomwe zili pa ma modules.

Onse a Mills ndi Solon amazindikira kuti vuto logwiritsa ntchito zolumikizira zotsika mtengo komanso/kapena kulumikiza izi ndi zolumikizira zina ndizosamveka, chifukwa cholumikizira pang'ono chimawonjezera pamtengo wonse wama module.

"Mukulankhula 1% ya ndalama zonse zomwe makampani azisunga kuti zifike zotsika mtengo," akutero Dean Solon wa ku Shoals.Akuti chifukwa cha zomwe akufotokoza kuti ndi zolakwika zopusa, gulu lake likuwonjezera mphamvu zozungulira 800 MW zamapulojekiti adzuwa omwe adakhazikitsidwa zaka zingapo zapitazo, kuphatikiza kusinthana kwamagetsi azinthu zamagetsi.

Ndipo ngakhale kulephera konse kwa cholumikizira kumabweretsa moto, pali zoopsa zenizeni - kuphatikiza kwa oyika."Sakumvetsetsa kuti kulumikizana kwa PV ndi komwe kuli koopsa kwambiri," akutero Mills.

“Kuchuluka kwa mphamvu zomwe zilipo panthawiyo n’zambiri.Ndi dongosolo lalitali kuposa chilichonse chomwe mungakumane nacho mnyumba mwanu, ndi kulumikizana kwa DC, ndipo kuli kunja. ”

Shoals 'Dean Solon akuti izi zitha kuyambitsanso nkhani zazikulu zamalamulo."Nthawi yoyamba yomwe munthu akagwidwa ndi magetsi, maloya adzakhala anthu osangalala kwambiri m'chipindamo."

Dean Solon, Brian Mills ndi Jan Mastny a LEONi akambirana za momwe angapewere moto, kuphatikizapo nkhani ndi zolumikizira, pa Quality Roundtable ya magazini ya pv pa chiwonetsero cha malonda cha Solar Power International ku Salt Lake City pa September 25. Kupezeka ndi kwaulere kwa omwe ali ndi SPI amadutsa.Dinani apa kuti mudziwe zambiri za chochitikachi ndikulembetsa.

Mungaganize kuti mapanelo angatumizidwe ndi chophimba chakuda kotero kuti sangathe kulumikiza choyikapo.

Oo.Ndinaganiza kuti zolumikizira zonsezi zinali zokhazikika.Iwo ayenera kukhala.Ndaona kuti khalidwe la opanga osiyana ndi osiyana kwambiri.Koma zolumikizira zonse zomwe ndaziwona zikuwoneka zofanana kwambiri komanso zimalumikizana.Vuto lalikulu pamenepo anthu.Bwino kuchita chinachake ASAP.

Potumiza fomu iyi mukuvomereza pv magazine kugwiritsa ntchito deta yanu ndicholinga chofalitsa ndemanga yanu.

Zambiri zanu zidzawululidwa kapena kutumizidwa kwa anthu ena ndicholinga chosefa sipamu kapena ngati izi zili zofunika pakukonza webusayiti.Kusamutsa kwina kulikonse kwa anthu ena sikungachitike pokhapokha ngati zili zomveka malinga ndi malamulo oteteza deta kapena ngati pv magazine ikukakamizika kutero.

Mutha kubweza chilolezochi nthawi ina iliyonse mtsogolomo, ndiye kuti zambiri zanu zidzachotsedwa nthawi yomweyo.Apo ayi, deta yanu idzachotsedwa ngati pv magazine yakonza pempho lanu kapena cholinga chosungira deta chakwaniritsidwa.
