Urebye inyuma yabakora 1500V, benshi muribi bigo bafite fotokolta nimbaraga za electronics, kandi nabo ni abizera b'indahemuka ba 1500V.

Mu nganda zifotora, kuva mu 2015, amashanyarazi ya 1500V yamenyekanye cyane mu Bushinwa.Muri iki gihe, sisitemu ya Photovoltaque imaze kubona ko ihinduka kuva 1000V ikagera kuri 1500V.Igiciro cya sisitemu yose irashobora gukizwa na 0.2 yuan / Wp, yagize uruhare mugutezimbere uburinganire bwamafoto kuri enterineti, nigikoresho cyo kuyobora amasosiyete yifotora kugirango avugurure.

Kuzamura ingufu za Photovoltaics byashyizeho urufatiro rwiza rwo kubika ingufu mubice bya elegitoroniki.Muri 2017, Sungrow yafashe iyambere mugutangiza sisitemu yo kubika ingufu za 1500V maze atangira kwimura tekinoroji y’amashanyarazi menshi kuva mu mafoto y’amashanyarazi yerekeza mu bubiko bw’ingufu.Kuva icyo gihe, ibice birenga 80% by'imishinga minini yo kubika ingufu za Sungrow byatangiye gukoreshwa ku masoko yo hanze nka Amerika, Ubwongereza, n'Ubudage byakoresheje sisitemu ya 1500V.

Mu imurikagurisha rya SNEC 2019, Kehua Hengsheng yerekanye igisekuru gishya cya 1500V 1MW / 2MWh yo mu bwoko bwa sisitemu yo kubika ingufu hamwe na 1500V 3.4MW Photovoltaic inverter booster imashini ihuza isi.

Kuva mu mwaka wa 2020, Ningde Times, Kelu, Kurinda NARI, Shuangyili, TBEA, na Shangneng Electric basohoye ibicuruzwa 1500V bijyanye no kubika ingufu, kandi iyi nzira ishobora kwihuta.

Kuri nyirubwite, ikintu cyonyine kigomba gusuzumwa ninikihe gisubizo kirahenze cyane hashingiwe kumutekano.

Ibigo bitanga amashanyarazi hagati harimo SPIC na Huaneng bimaze kwerekana no kugenzura niba bishoboka uburyo bwo kubika ingufu za 1500V.Muri 2018, Hydropower Hydroower yafashe sisitemu yo kubika ingufu za 1500V nkumugambi wingenzi wo kugenzura ahabigenewe kubika ingufu, kandi izaba muri 2020. Sisitemu yo kubika ingufu za 1500V ikoreshwa mubice biri mumashanyarazi abika ingufu zishyigikira Umushinga UHV.Umushinga wa Mendi wa Huaneng mu Bwongereza nawo ukoresha sisitemu ya 1500V.

Umusesenguzi muri Bloomberg New Energy Finance yemeza ko niba ibicuruzwa ari byiza cyangwa bidakenewe kugenzura isoko.Niba 1500V ishobora kurya hafi yisoko, irashobora kwerekana ko ibicuruzwa cyangwa igiciro bifite inyungu.

Nkuko amakimbirane ya ternary na fer-lithium, inyuma yamasosiyete menshi, cyane cyane abafite amafoto ya fotora, bahitamo cyane kuri 1500V, ni uguharanira uburenganzira bwo kuvuga mubuhanga.Mumaso yabakora imyitozo myinshi ya fotora, gushiraho ububiko bwingufu kuruhande rwa DC no kugabana inverter hamwe na sitasiyo yamashanyarazi niyo ntego zabo ziterambere.

Nibyo, inganda nzima ntizigomba na rimwe kugira ijwi rimwe gusa.Inganda zo kubika ingufu muri iki gihe ziri mu bihe aho inzira nyinshi za tekiniki zibana kandi indabyo ijana zirabya, kandi ni ibihe byuzuye impaka.

Kandi ubu bwoko bw'amakimbirane ni ikimenyetso cyiterambere.Tekinoroji yose ntabwo itunganye, kandi ibigo bigomba gukomeza urwego runaka rwo gufungura.Iyo inzira ishingiye ku nzira imaze gushingwa, iyo abantu bahuye nigisubizo gishya cya tekiniki, akenshi babigereranya nubushake bwabo bwite, hanyuma bagafata icyemezo vuba.

Mu myaka mike ishize, ubwo tekinoroji ya monocrystalline ya Photovoltaque yari imaze kuvuka, ibigo bya polycrystalline ntibyashoboye guhindura imyumvire yabyo, bizera ko monocrystalline ifite amafaranga menshi, kwiyitaho cyane, kandi "imikorere" ni izina ryubusa.Amaherezo, iyobowe na Li Zhenguo, Longi yafashe ubundi buryo maze yigarurira akarere kanini ku butaka bwa monocrystalline ya Photovoltaque.

Hamwe n "" imbaraga nshya + ububiko bw'ingufu "buhoro buhoro biba inzira, ubwihindurize bwa sisitemu yo kubika ingufu bugana ku bushobozi bunini ntabwo bwahagaze.By'umwihariko mu gihe hatabayeho uburyo bwo kugenzura ibiciro, gutangaza politiki yo gushyiraho ububiko bw’ingufu ziyongera ku ruhande rushya rw’ingufu byashyizeho igitutu kinini ku musaruro w’ishoramari ku bateza imbere ingufu nshya.Nigute wagabanya neza ikiguzi cya sisitemu yo kubika ingufu no kunoza imikorerekubyara ingufu biracyari ejo hazaza ho kubika.Ingingo yibanze yiterambere ryinganda.

Bamwe mu basesenguzi bemeza ko gukemura ibyo bibazo bibiri by'ingenzi, “cryptography” bikiri mu guhanga udushya.Umuvuduko mwinshi nimwe mumahuriro yingenzi yo guhanga udushya.Niba 1500V ishobora kuzamurwa cyane mugihe gito biterwa nuko inganda zishobora kugera kumacakubiri asanzwe mubijyanye nibikorwa bya tekiniki, umutekano, ubuzima nigiciro.
