Ndikukula kosalekeza kwa msika wamkati wa photovoltaic, kufunika kwaphotovoltaic mphambano mabokosindizolumikiziraakupitiriza kukula.Komabe, chifukwa cha chiŵerengero chotsika mtengo ndi ntchito "yosaoneka bwino", khalidwe la mabokosi ophatikizika ndi zolumikizira zasinthidwa, zomwe zimapangitsa kuti nthawi zambiri kulephera komanso ngozi za magetsi a photovoltaic apangidwe ndi dongosolo.Mavuto omwe ali ndi zolumikizira awululira pang'onopang'ono, kotero ogula ndi opanga ayamba kuzindikira kufunika kwa khalidwe la mankhwala.
Ndi kuchepa kwachangu kwa mtengo wamagetsi opangira magetsi a photovoltaic, mtengo wa kukhazikitsa kwa photovoltaic kunyumba ndi pafupifupi 6 yuan/W.M'tsogolomu, zikuyembekezeredwa kuti padzakhala kuchepetsa 10% -15% chaka chilichonse.Nthawi yomweyo, mu 2020, madera ambiri ku China adzakwaniritsa kufanana pa intaneti, chomwe ndi chinthu chamkati cha chitukuko chofulumira cha photovoltaics zapakhomo.
Kutsika kwa mtengo wamagetsi pa ola la kilowatt, njira yofikira pa intaneti yokhazikika, ndi ndondomeko yokhazikika ya subsidy ndi zitsimikizo zofunika kuti ma photovoltaics apanyumba alowe m'nyumba za anthu wamba ngati katundu wogula + katundu wandalama.
Komabe, ndi kukula kofulumira kwa mphamvu zoyikapo m'misika yapakhomo ndi yakunja ya photovoltaic m'zaka zaposachedwa, zoopsa zamtundu zili paliponse.Momwe mungawonetsere chitetezo ndi ntchito yodalirika ya machitidwe a photovoltaic apanyumba akukhala amodzi mwa malo okhudzidwa kwambiri pamakampani a photovoltaic.
Malinga ndi Ling Zhimin, CEO wa Phenergy Technology Co., Ltd., "Kuphulika kwa zinthu zapakhomo mu 2016 ndi 2017 kunali koopsa komanso kwachangu.Aka ndi gawo loyamba lachitukuko choyipa cha China chogawidwa cha photovoltaic.Ndi kuwonjezeka kwa mphamvu zokhazikitsidwa Mochulukirachulukira, mavuto ambiri monga moto, madandaulo a ogwiritsa ntchito, ndi kusakhulupirika kwa ngongole zidzawonekera pang'onopang'ono.Kenako, ma photovoltais omwe amagawidwa adzalowa gawo lachiwiri la chitetezo ndi luntha. "
Kafukufukuyu akuwonetsa kuti pamavuto ndi ngozi zonse zapamalo opangira magetsi, ngozi zomwe zimachitika chifukwa cha mabokosi ophatikizika ndi zolumikizira zimapitilira 30%, ndipo kuwonongeka kwa mabokosi ophatikizika kumapangitsa kuti pakhale ngozi zopitilira 65% zamabokosi ophatikizika ndi zolumikizira.
Malinga ndi akatswiri amakampani, kutenga zolumikizira za dzuwa monga mwachitsanzo, chifukwa cha kukula kwawo kochepa komanso ndalama zowerengera ndalama zosakwana 1% za mtengo wonse wamagetsi a photovoltaic, nthawi zambiri amanyalanyazidwa ndi opanga ndi ogwiritsa ntchito.
Cheng Ziyu, wamkulu wa TÜV Rheinland Shanghai's solar component smart junction box business, adati ngakhale aliyense amayang'ana kwambiri malo omwe ali ndi ukadaulo wa batri komanso kusintha kwamphamvu kwa ma module, nthawi zambiri amanyalanyaza zida zazing'ono koma zofunika kwambiri za mphamvu yadzuwa.Zigawo, zomwe zimabweretsa ukadaulo wabwino wa batri ndi zida zabwino sizingagwiritsidwe ntchito moyenera, komanso kuvulaza mukamagwiritsa ntchito.
Kuphatikiza apo, ambiri opanga zolumikizira zapakhomo alibe luso lodziyimira pawokha komanso luso lachitukuko, ndipo osungira magetsi amasokonekera mokwanira komanso njira zowunikira zowunikira, zomwe zimapangitsa kuti pakhale mavuto osiyanasiyana omwe akuwonekera pakugwiritsa ntchito cholumikizira, monga kukana kukhudzana, chipolopolo chakunja. deformation, arcing moto pa kugwirizana, kapena kusungunuka ndi kuyaka.Sizimangokhudza kugwira ntchito kwa malo opangira magetsi a photovoltaic, komanso kumayambitsa masoka osasinthika ndi kutayika pazochitika zazikulu.
Malinga ndi Dr. Zhimin Ling: "Mu dongosolo la zingwe zachikhalidwe, ma modules amakonzedwa motsatizana ndi DC high voltage ya 600V-1000V.Dongosololi limagwira ntchito kwa zaka zambiri, ndipo kutsekemera kwa waya kumawonekera pambuyo pa dzimbiri, zomwe zimakhala zosavuta kupanga ma DC arcs ndikuyambitsa moto.Moto ukachitika, mbali ya DC, bola ngati pali kuwala, padzakhala mphamvu yamagetsi, ndipo ozimitsa moto sangathe kuzimitsa motowo. "
Pamene dongosolo la photovoltaic limayang'aniridwa ndi mphepo, mvula, dzuwa lotentha komanso kutentha kwakukulu kwa nthawi yaitali, zolumikizira ziyenera kugwirizanitsa ndi malo ovutawa, choncho sayenera kukhala opanda madzi, kutentha kwambiri komanso kutentha kwa nyengo. cheza cha ultraviolet, komanso chitetezo chokhudza komanso kulemedwa kwakukulu Kuthamanga komanso kuchita bwino kwambiri.
Zopanga za Photovoltaic zimafuna moyo wazaka zosachepera 25, ndipo bokosi la photovoltaic junction ndi chimodzi mwa zinthu zofunika kwambiri za photovoltaic modules, zomwe zimagwira ntchito yofunika kwambiri pakupanga mphamvu kwa nthawi yaitali, yotetezeka komanso yothandiza.
A Luo Jiuwei, wapampando wa Shenzhen Ruihexiang Technology Co., Ltd., adanenanso zomwezo ndipo adapempha makampaniwo kuti apititse patsogolo zinthu."Timatsogolera msika ndi khalidwe, chifukwa photovoltaics idzatenga zaka 20 kuti igwiritse ntchito, choncho khalidwe la mankhwala ndilofunika kwambiri.Komabe, pali mitengo yamtengo wapatali komanso yotsika pamsika, ndipo opanga ena amadyera zotsika mtengo komanso amanyalanyaza zabwino.Izi sizingatheke.Tiyenera kukhala ndi moyo wabwino. ”
Zolumikizira za Photovoltaic ndi ma node otumizira mphamvu.Ma nodewa amatulutsa kutentha mphamvu ikadutsa, yomwe ndi kugwiritsa ntchito mphamvu moyenera.Mlozera wowunikira kwambiri waubwino wa zolumikizira za photovoltaic ndi "kukana kulumikizana kwa zolumikizira zachimuna ndi zazikazi pambuyo pa kuswana".Cholumikizira chapamwamba kwambiri chimayenera kukhala ndi kukana kotsika kwambiri, kuchepetsa gawo ili la kutayika, ndikutha kukhalabe ndi kukana kukhudzana kwapang'onopang'ono m'moyo wonse, ndiko kuti, kukana kwapafupipafupi kukhudzana.
Malinga ndi malipoti, kukana kolumikizana kwa zolumikizira zapamwamba za photovoltaic ndizokhazikika kwambiri, zomwe zimachitika makamaka chifukwa chaukadaulo wolumikizira magetsi womwe umagwiritsidwa ntchito.Zolumikizira zotsika zimakhala zovuta komanso zosagwirizana mkati ndipo zimakhala ndi malo ochepa olumikizirana, zomwe zimapangitsa kukana kwambiri kuyatsa bokosi lolumikizirana, lomwe limawotcha chigawo chakumbuyo ndikupangitsa kuti chigawocho chisweke.Kulumikizana koyambirira kwa cholumikizira kumadalira kusankha kwazinthu, kapangidwe kake komanso ngati ili ndi ukadaulo wapakatikati wolumikizira magetsi.Kukana koyambirira kolumikizana kwa Stäubli MC4 ndi 0.35mΩ, womwe ndi wokwera kwambiri.Kutengera chinthuchi chokha, MC4 imabweretsa chiwonjezeko cha ma yuan masauzande ambiri kwa eni ake pa MW chaka chilichonse.
Malinga ndi muyezo waposachedwa wapadziko lonse wa IEC 62852 wolumikizira ma photovoltaic, kukana kwa zolumikizira za amuna ndi akazi pambuyo poyesedwa ndi TC200+DH1000 sikungachuluke kuposa 5 mΩ kapena kukana komaliza kumakhala kosakwana 150% ya mtengo woyamba.Izi ndi zofunika zochepa chabe, ndipo kukana kukhudzana kwa zolumikizira opanga osiyanasiyana kumadalira luso la wopanga.
Kukula kwapamwamba kwa msika wa photovoltaic connector kumafuna kuyesetsa kwa makampani onse kuti atulutse zinthu zotsika mtengo mwamsanga ndikusunga malo kuti msika ukhale wathanzi.
Pakalipano, vuto lalikulu la ambiri opanga photovoltaic cholumikizira akadali mu khalidwe, ndipo ngati amaloledwa kukhala, otsika mankhwala opanga ena angasokoneze mbiri ya lonse Chinese photovoltaic cholumikizira makampani.Zotsatira zake, makasitomala ali ndi malingaliro osadalirika a zolumikizira za photovoltaic zopangidwa ku China.
China Quality Certification Center kamodzi anaitana, pofuna kuonetsetsa khalidwe la zolumikizira AC kwa kachitidwe photovoltaic m'dziko langa, kuthetsa mkangano wa mankhwala pa msika zoweta, kupititsa patsogolo chitetezo ntchito inverters, kachitidwe photovoltaic ndi zomera photovoltaic mphamvu, ndi kulinganiza kupanga makampani olumikizira.Kulimbikitsa chitukuko chabwino cha mafakitale a photovoltaic, m'pofunika kupanga mfundo zofanana za dziko kapena luso lamakono.
Kuyika pamodzi zolumikizira pakati pa mitundu yosiyanasiyana kumakhalanso vuto lalikulu kwambiri pakugwiritsa ntchito zolumikizira za photovoltaic.Malinga ndi lipoti la kafukufuku wakunja, kuyika kolumikizira kosakanikirana ndi kuyika kolumikizira kosakhazikika kunayika zomwe zimayambitsa moto ndi zitatu.
Nthawi zonse pamakhala vuto pamsika wolumikizira photovoltaic, ndiko kuti, kugwiritsa ntchito kosakanikirana kwa zinthu zosiyanasiyana zolumikizirana komanso kuphatikizika kwa zolumikizira pakati pamitundu yosiyanasiyana.Chodabwitsa ichi ndi chofala m'misika yapakhomo ndi yakunja.Eni ake ambiri ndi makampani a EPC sadziwa pang'ono za kufanana kwa zolumikizira.
Komabe, mafotokozedwe, miyeso ndi kulolerana kwa zolumikizira za opanga osiyanasiyana sizikugwirizana ndipo sizingafanane kwathunthu.Zolumikizira ziwirizo zitalumikizidwa, ma conductor omwe amagwiritsidwa ntchito polumikizira magetsi pakati pa zolumikizira ziwirizo samalumikizana bwino, zomwe zimapangitsa kuti pali kulephera kwa kulumikizana.
Hong Weigang, Woyang'anira Dipatimenti ya Photovoltaic Product of Electrical Connectors ku Stäubli (Hangzhou) Precision Machinery Electronics Co., Ltd., anati: "Zolumikizira zochokera kwa opanga osiyanasiyana zimakhala ndi njira zopangira zosiyana kwambiri, miyezo yopangira, ndi zipangizo.Mavuto okhudzana ndi kuphatikizika kwa zolumikizira kumaphatikizapo kukana kukhudzana, kutulutsa kutentha kwa cholumikizira, moto pa cholumikizira, kutenthedwa kwa cholumikizira, kulephera kwamphamvu kwa zigawo za zingwe, kulephera kwa bokosi lolumikizirana, ndi kutayikira kwa zigawozo, zomwe zingapangitse kuti dongosololi lilephere kugwira ntchito bwino.Phindu lazachuma la malo opangira magetsi motero limasokonekera.Ngati mankhwala ochokera kwa wopanga yemweyo agwiritsidwa ntchito, chiwopsezochi chidzawongoleredwa mkati mwazowongolera.“
An Chao, woyang'anira bizinesi yamafakitale amagetsi ndi makina a TÜV Rheinland Solar Services, adatsimikiza kuti zolumikizira dzuwa zimayenera kulabadira zovuta zomwe zimagwirizana.Nkhaniyi yadzutsidwa ndi mabungwe oyesa a chipani chachitatu kwa zaka zambiri.Choncho, zolumikizira siziyenera kusakanikirana panthawi yoyika magetsi a photovoltaic.
Pachifukwa ichi, mabungwe oyezetsa ovomerezeka a TUV ndi UL onse apereka ziganizo zolembedwa kuti sagwirizana ndi zolumikizira zamitundu yosiyanasiyana.Ku Australia, boma lalemba zofunikira zomanga malo opangira magetsi kuti agwiritse ntchito zolumikizira kuchokera kwa wopanga yemweyo m'malamulo kuti apewe ngozi.Koma m'dziko lathu, palibe miyezo yoyenera yomwe yaperekedwa pamsika.
Mu 2013, China Quality Certification Center idanenanso kuti ndikugwiritsa ntchito kwambiri ma inverters ang'onoang'ono m'makina a photovoltaic m'tsogolomu, zolumikizira zambiri za photovoltaic AC zidzayikidwa pamsika.Ubwino wa cholumikizira cha AC umagwirizana mwachindunji ndi chitetezo cha inverter ndi dongosolo lonse la photovoltaic.Pakadali pano, chifukwa China ilibe zofunikira zamayiko ndi miyezo yamakampani, komanso kusowa kwaukadaulo wofunikira, opanga ma inverter amasankha zolumikizira zokwera mtengo za AC zomwe zimakwaniritsa zofunikira zazinthu zakunja za photovoltaic potumiza kunja.Komabe, ku China, zolumikizira zotsika za AC zimagwiritsidwa ntchito, zomwe zimapangitsa kuti pakhale ngozi zachitetezo m'ma inverters apanyumba, makina amtundu wa photovoltaic, komanso magetsi onse a photovoltaic.
Hong Weigang adati: "Pali ambiri opanga zigawo zapakhomo, ndipo ali ndi ogulitsa akuluakulu ndi okhazikika a zipangizo, mabokosi ophatikizira, zolumikizira, zingwe, ndi zina zotero. , ndi kusowa kwa miyezo Chidziwitso chayambitsa kusamvana kwina mu malingaliro a kampani a ntchito zolumikizira.Kuphatikiza apo, maphunziro a ogwira ntchito oyika sikokwanira.Pakuyika, mtunduwo ndi wachisokonezo.“
Ngati cholumikizira chikalephera, chidzabweretsa ndalama zambiri zogwirira ntchito ndi kukonza, kuphatikiza kutayika kwa magetsi, zida zosinthira, ndalama zogwirira ntchito komanso zoopsa zachitetezo.
Pakalipano, msika wa photovoltaic wogawidwa ndi wotentha kwambiri, ndipo amakhulupirira kuti anthu ambiri okhalamo kapena madenga a mafakitale ndi amalonda adzakhala ndi machitidwe a photovoltaic m'tsogolomu.Ndipo ngati zolumikizira pamakinawa zikulephera, kuthetseratu kwake ndikusinthanso kudzakhala kovuta kwambiri kwa ogwira ntchito ndi okonza: choyamba, chovuta chimakhala chachikulu, chachiwiri ndikuwonjezeka kwa ngozi zachitetezo chamunthu.Zinthu zoopsa, monga moto, zidzabweretsa kuwonongeka kwachuma ndi mbiri kwa eni ake.Izi ndizochitika zomwe aliyense safuna kuziwona.
Ngakhale cholumikizira cha photovoltaic ndi chaching'ono, ngati chitsanzocho chisankhidwa bwino, chikhoza kukhala "chochepa komanso chokongola", chomwe chidzabweretse phindu lalikulu kwa mwiniwake.M'malo mwake, idzakhala nkhani yaminga pakugwira ntchito kwa malo opangira magetsi, ndipo idzaba ndalama zambiri za eni ake mosawoneka komanso pang'onopang'ono.
Masiku ano, opanga photovoltaic system azindikira kufunika kwa zolumikizira.Hong Weigang amakhulupirira kuti: "Makampani opanga ma photovoltaic akhala akukula m'dziko lathu kwa zaka zambiri.Kupyolera mu zaka 3-5 zogwiritsira ntchito, malo opangira magetsi awonetsa pang'onopang'ono mavuto ambiri.Makasitomala amatha kuphunzira zambiri zamakina kuchokera kumayendedwe angapo, ndikuzindikira pang'onopang'ono kufunikira kwa zolumikizira..”
Pofuna kutsimikizira mtundu wa fakitale wa zolumikizira za photovoltaic, opanga zolumikizira amapereka zitsimikizo zofananira zachitetezo pazolumikizira zawo.
Shenzhen Ruihexiang Technology Co., Ltd. imatsindika kwambiri kuwongolera kwazinthu zopangira.Iwo anati: “Cholumikizira cha dzuwa chimagwiritsa ntchito pulasitiki yakuda, izi ndizovuta kwambiri.Popeza idzagwiritsidwa ntchito panja kwa zaka 25, zipangizo wamba sizingakwaniritse zofunikira.Timayang'ana makamaka zida.Chinsinsi chachiwiri ndi kupanga.Ndiye pali maphunziro a installers. "
Huachuan adatsindika za certification ndi kuyesa kwazinthu: "Zogulitsa zonse za photovoltaic zopangidwa ndi Zerun zadutsa chiphaso cha TÜV Rheinland, ndipo tachitanso kuwongolera mkati mwakampani.Mwachitsanzo, kuyesa kukalamba kwazinthu zathu kumafuna kuwirikiza kawiri muyezo wa IEC.Zimakhalapo katatu kapena kupitilira apo. ”
Malingaliro a kampani Dongguan Slocable Photovoltaic Technology Co., Ltd.adagogomezera zomwe zachitika komanso ndalama mu R&D ndi kupanga: "Choyamba, takhala tikupanga zolumikizira za photovoltaic kuyambira 2008 mpaka pano, ndipo tili ndi zaka zopitilira khumi za R&D ndi luso lopanga.Chachiwiri, tili ndi labotale yolumikizira photovoltaic tokha.Pofuna kuonetsetsa kuti zinthu zili bwino, chinthu chilichonse chidzayesedwa ndikuyesedwa kangapo musanachoke ku fakitale kuti apereke chitsimikizo cha chitetezo kwa cholumikizira.Komanso, zinthu zathu zonse za photovoltaic zili nazozitsimikizo za satifiketindipo adadutsa certification ya TUV, satifiketi ya CE komanso satifiketi ya IP68 yapamwamba kwambiri yopanda madzi ndi zina zotero. ”
Malinga ndi Hong Weigang, Stäubli yapanga ukadaulo wake wokhazikika pakutsimikizira zamtundu."Tekinoloje yayikuluyi ndi chala cholumikizana ndi zingwe (ukadaulo wa MULTILAM).Ukadaulo uwu umawonjezera chitsulo chapadera chopangidwa ngati chingwe pakati pa zolumikizira zachimuna ndi zazikazi za cholumikizira kuti zilowe m'malo mwazomwe zimalumikizana zosagwirizana ndikuwonjezera kwambiri kulumikizana kothandiza.Dera, lomwe limapanga gawo lofananira, lomwe lili ndi mphamvu zambiri zonyamulira, kutayika kwamphamvu pang'ono ndi kukana kulumikizana, kukana kukhudzidwa, kukana kwa dzimbiri komanso kukana kutentha kwambiri, ndipo kumatha kukhalabe ndi ntchitoyi kwa nthawi yayitali. ”
