Imirasire y'izuba ituye imara igihe kingana iki?

Mugice cyambere cyuruhererekane, ikinyamakuru pv cyasuzumyeubuzima butanga umusaruro w'izuba, Birashobora kwihangana. Muri iki gice, turasuzuma imirasire y'izuba ituye muburyo butandukanye, igihe bimara, nuburyo bihangana.

Inverter, igikoresho gihindura ingufu za DC zakozwe nizuba rikoresha ingufu za AC zikoreshwa, zirashobora kuza muburyo butandukanye.

Ubwoko bubiri bwingenzi bwa inverters mubisabwa gutura ni imirongo ihinduranya na microinverters. Muri porogaramu zimwe, imirongo ihinduranya ifite ibikoresho bya module-urwego rwamashanyarazi (MLPE) bita DC optimizers. Microinverters na DC optimizers ikoreshwa mubisanzwe hejuru yinzu igicucu cyangwa icyerekezo cyiza (ntabwo kireba amajyepfo).

Mubisabwa aho igisenge gifite azimuti ikunzwe (icyerekezo cyizuba) kandi ntakibazo gicucu, umugozi inverter urashobora kuba igisubizo cyiza.

Imirongo ihindagurika muri rusange izana insinga zoroheje hamwe n’ahantu hamwe kugirango hasanwe byoroshye nabatekinisiye b'izuba.Mubisanzwe ntabwo bihenze,yavuze izuba. Inverters irashobora kugura 10-20% yumuriro wizuba wose, guhitamo rero ni ngombwa.

Bimara igihe kingana iki?

Mugihe imirasire yizuba ishobora kumara imyaka 25 kugeza 30 cyangwa irenga, inverter muri rusange zifite ubuzima bucye, kubera ibice byashaje byihuse. Inkomoko isanzwe yo kunanirwa muri inverter ni kwambara amashanyarazi ya mashini kuri capacitor muri inverter. Imashanyarazi ya electrolyte ifite igihe gito cyo kubaho no gusaza byihuse kuruta ibice byumye,ati Solar Harmonics.

IngufuSage yavuzeko indangantego isanzwe yo guturamo inverter izamara imyaka 10-15, bityo bizakenera gusimburwa mugihe runaka mubuzima bwikibaho.

Imirongo ihindagurikamuri rusangegaranti isanzwe iri hagati yimyaka 5-10, benshi bafite amahitamo yo kugeza kumyaka 20. Amasezerano amwe amwe akubiyemo kubungabunga no kugenzura kubuntu mugihe cyamasezerano, nibyiza rero kubisuzuma muguhitamo inverter.

Microinverters ifite ubuzima burebure, EnergySage yavuze ko zishobora kumara imyaka 25, hafi nkigihe kimwe na bagenzi babo. Roth Capital Partners yavuze ko umubano w’inganda muri rusange utangaza ko microinverter yananiwe ku gipimo kiri hasi cyane ugereranije n’imigozi ihindagurika, nubwo igiciro cyo hejuru muri rusange kiri hejuru cyane muri microinverters.

Microinverters mubisanzwe ifite garanti yimyaka 20 kugeza 25. Twabibutsa ko mugihe microinverters ifite garanti ndende, iracyari tekinolojiya mishya kuva mumyaka icumi ishize cyangwa irenga, kandi haracyari kurebwa niba ibikoresho bizasohoza amasezerano yimyaka 20+.

Kimwe kijya kuri DC optimizers, mubisanzwe ihujwe numurongo uhuza inverter. Ibi bice byateguwe kumara imyaka 20-25 kandi bifite garanti yo guhuza icyo gihe.

Naho abatanga inverter, ibirango bike bifite umugabane wamasoko yiganje. Muri Reta zunzubumwe zamerika, Hindura umuyobozi wisoko rya microinverters, mugihe SolarEdge iyoboye imigozi ihinduranya. Tesla yagiye itera umuraba mu kibanza cy’imiturire ihindagurika, ifata imigabane ku isoko, nubwo hakiri kurebwa ingaruka ingaruka kwinjira ku isoko rya Tesla bizagira ingaruka, nk'uko byatangajwe n’inganda n’abafatanyabikorwa ba Roth Capital Partners.

Kunanirwa

Ubushakashatsi bwakozwe na kWh Analytics bwerekanye ko 80% byizuba ryizuba ryizuba bibaho kurwego rwa inverter. Hariho impamvu nyinshi zibitera.

Ukurikije Fallon Solutions, Impamvu imwe ni grid amakosa. Umuvuduko mwinshi cyangwa muto kubera amakosa ya gride urashobora gutuma inverter ihagarika akazi, kandi imashini zangiza cyangwa fus zirashobora gukora kugirango zirinde inverter kunanirwa n’umuriro mwinshi.

Rimwe na rimwe, gutsindwa birashobora kugaragara kurwego rwa MLPE, aho ibice bigize optimizers bigaragarira ubushyuhe bwo hejuru kurusenge. Niba umusaruro ugabanutse urimo kuboneka, birashobora kuba amakosa muri MLPE.

Kwiyubaka bigomba gukorwa neza. Nkuko bisanzwe bigenda, Fallon yasabye ko ingufu zizuba zigomba kugera kuri 133% yubushobozi bwa inverter. Niba panne idahuye neza na in-inverter iburyo, ntabwo izakora neza.

Kubungabunga

Kugirango inverter ikore neza mugihe kirekire, nibirasabwakwinjizamo igikoresho ahantu hakonje, humye hamwe numwuka mwinshi uzunguruka. Abashiraho bagomba kwirinda ahantu hafite urumuri rwizuba rutaziguye, nubwo ibirango byihariye byo guhinduranya hanze byashizweho kugirango bihangane nizuba ryinshi kurenza abandi. Kandi, mubice byinshi-byinjizamo, ni ngombwa kumenya neza ko hari itandukaniro rikwiye hagati ya buri inverter, kugirango hatabaho ihererekanyabubasha hagati ya inverter.

Nibyiza kwimenyereza kugenzura hanze ya inverter (niba bishoboka) buri gihembwe, ukareba ko nta bimenyetso bifatika byangiritse, kandi imyanda yose hamwe nudukonjesha dukonje nta mwanda numukungugu.

Birasabwa kandi guteganya igenzura binyuze mumashanyarazi yemewe yizuba buri myaka itanu. Ubugenzuzi busanzwe bugura amadorari 200- $ 300, nubwo amasezerano yizuba amwe afite kubungabunga no kugenzura kubuntu mumyaka 20-25. Mugihe cyo kugenzura, umugenzuzi agomba kugenzura imbere muri inverter kugirango agaragaze ibimenyetso byangirika, ibyangiritse, cyangwa udukoko.
