Kugereranya ububiko bwa bateri n'uruzitiro-Izuba ry'izuba ryonyene
Kugira ngo kwongerako amabateri ku nzira yawe y’izuba bibe bifise insiguro, bivana n’ivyo urimwo be n’ivyo ushira imbere.
Ugupima urusenga n'ububiko bwa bateri
Ipima ry'urusenga ry'ubudandaji ryuzuye-rikoresha cane cane uruzitiro nk'ibati-izuba ryinshi ku murango rironka inguzanyo zisubiza inyuma ijoro rikoreshwa ku rugero rumwe. Muri ivyo bihe, amabateri yongera igiciro ata nyungu y’amahera igaragara kiretse uha agaciro amashanyarazi yo gusubiza inyuma iyo azimye. Ariko rero, ugupima kwuzuye-ugupima urusenga rw’ubudandaji biriko biragenda biragabanuka uko amashirahamwe y’amazi ahindukira akaja ku gihe-c’ibiciro vy’ugukoresha -n’ugugabanya agaciro k’inguzanyo zo gushora hanze.
Mu gihe ca California NEM 3.0, ibiciro vyoherezwa hanze bishika ku madolari 0.05-$0.08 ku kWh mu gihe ibiciro vy’ugucuruza biva ku madolari 0.30-$0.52 ku kWh bivanye n’isaha y’umusi. Ububiko bwa bateri buragufasha gufata agaciro k'ubudandaji kose-bishoboka $0.40+ kuri kWh-aho kugurisha ku $0.06. Ikibazo c’ivy’amahera gica gikomeye iyo itandukaniro ry’igiciro c’ivyoherezwa hanze n’ugucuruza rirenze amadolari 0,20 ku kWh.
Ivyiyumviro vyo kwizigirwa
Ukwizigirwa kw’uruzitiro kuratandukanye cane bivanye n’aho umuntu ari. Uturere dukunda guhagarara canke tugamara igihe kirekire, turaronka inyungu nyinshi mu gukoresha amabateri. California ihanganye n’uguhagarika umutekano mu gihe c’umuriro. Texas yarashikiwe n’ibihuhusi vy’urushana vy’agahomerabunwa birengeye ubushobozi bw’uruja n’uruza. Uturere dushobora guterwa n'inkubi y'umuyaga-tugira ingorane z'uguhagarara kw'imisi myinshi inyuma y'ibihe bikomeye.
Ku nzu zishingiye ku mapompa y’amariba, ibikoresho vyo kuvura canke ibiro vyo mu nzu, mbere n’uguhagarara kw’amashanyarazi mu gihe gitoyi biratuma habaho uguhungabana gukomeye. Ububiko bwa bateri buratanga amahoro yo mu mutima arenga imibare y’amahera. Ivyo bivuzwe, ukuzimangana kw'amashanyarazi gake cane bishobora kutaba ari vyo bituma umuntu akoresha amadolari 10,000+ mu gukoresha amabateri gusa kugira ngo akoreshe amadolari 500 yoshobora guhagije iyo udashize imbere gukoresha izuba.{6}}.
Kazoza-Gushingira intahe
Imiterere y'igipimo c'ubuhinga irabandanya gutera imbere ija ku gihe-c'-ikoreshwa ry'ibigereranyo bituma kwikoresha -kugira agaciro. Ububiko bwa bateri buragushira mu kibanza co kuzigama cane uko ayo mahinduka yihuta. Ikindi, ubuhinga bw’imodoka-ku-inzu (V2H) bushobora gutuma amaherezo imodoka zikoresha umuyagankuba zikora nk’amabateri yo mu nzu, bikaba bishobora kugabanya ivy’ugukenera ubuhinga bwo gukoresha amabateri yo mu nzu yihariye-naho ivyo biguma imyaka myinshi kure y’uko abantu benshi babikoresha.
Ibibazo bikunze kwibazwa
None ubuhinga bwo kubika inguvu z’amabateri y’izuba buzotwara angahe mu mwaka w’2025?
Ivyo bikoresho vyose bishizweho bigura amadolari 8.000-16.000 bivanye n’ubushobozi n’ibara. Igiciro ca mbere kigenda nk’amadolari 1.300 ku kWh imbere y’uko 30% y’umusoro wa Leta itanga, ivyo bikaba bigabanya igiciro kikaja ku madolari 900-1.000 ku kWh net. Ubuhinga busanzwe bw’ama kWh 10 bugura amadolari 12.000 iyo bushizweho, canke amadolari 8.400 inyuma y’ugutanga umusoro iyo bushizweho bitarenze igenekerezo rya 31 Kigarama 2025.
Amabateri y’izuba amara igihe kingana iki?
Bateri za litiyumu zimara imyaka 10-15 imbere y’uko zishika ku 70-80% vy’ubushobozi bwazo bwa mbere. Benshi mu bakora amabateri baratanga garanti y’imyaka 10 canke 3.000-8.000 y’ugushaja. Ubuzima nyabwo buvana n'uko bukoreshwa, ubushuhe bushirwa ahabona, n'uburebure bw'ibisohoka. Bateri zikoreshwa n’amabuye y’agaciro zimara imyaka 3-5 gusa kandi zisaba gutunganywa ubudasiba.
Noshobora kwongerako uburyo bwo kubika inguvu z’amabateri y’izuba ku bikoresho vyanje vy’izuba biriho?
Ego cane, uburyo bwo kubika inguvu z’amabateri y’izuba burashobora gusubirwamwo ku bikoresho vyinshi vy’izuba vyariho. AC-uburyo bwa bateri bukorana n'imiterere yose y'izuba, naho uzokenera umwanya mu gipande c'umuyagankuba wawe kandi ushobora gusaba guhindura uruhusha. Ivyo gushiramwo ibintu bifata imisi 1-2, kandi ibiciro bisa n’ivyo gushiramwo ibintu bishasha. Inverter zimwe zimwe za kera zishobora gusaba ko zihindurwa kugira zikore neza n’imirongo y’amabateri.
Ni ubushobozi bungana iki bwo gusubiza inyuma nkeneye inzu yanje?
Mubanze muharure imitwaro yanyu y’ingenzi. Ivyuma bihambaye nk’amafirigo, amatara, n’ibikoresho vyo guhanahana amakuru bikeneye 5-8 kWh ku musi. Gucungera inzu yose harimwo HVAC, gushusha amazi, n’ibikoresho vyose bisaba 25-35 kWh ku musi. Benshi mu bafise inzu bashimika ku misi 1-2 yo gucungera umuzigo uhambaye, bikaba vyerekana ko bateri ishobora gukoresha 10-15 kWh. Amatara y’izuba aratuma ivyo bigenda neza cane mu gusubiramwo amabateri ku murango.
Gufata ingingo yo kubika bateri
Uburyo bwo kubika inguvu z’amabateri y’izuba buratanga agaciro nyakuri ku bafise inzu barondera kwigenga mu bijanye n’inguvu, umutekano w’inguvu z’inyuma, canke kuzigama cane ingufu z’izuba mu bice bifise ubuhinga bwo gupima inguvu butari bwiza. Iryo koraniro ryarakuze cane, amabateri ya litiyumu-ion atanga ubushobozi bwo kwizigirwa, buramba-busaba kwitaho bike.
Ivy’amahera birakomera cane iyo inguzanyo y’ikori ya Leta Zunze Ubumwe za Amerika igumaho. Inyuma y’igenekerezo rya 31 Kigarama 2025, 30% ITC irazimangana kubera ububiko bwa bateri, ivyo bikaba bituma amafaranga y’ingirakamaro yongera hafi 43%. Ifatanijwe n’inkurikizi z’akarere, iri dirisha ritoyi ritanga ubutunzi buteye umunezero ku migambi yarangijwe imbere y’uko umwaka-uhera.
Ku mazu yo mu turere dukunda kuzima, ibiciro vy’amashanyarazi bizimvye, canke amasezerano make y’ugupima, uburyo bwo kubika inguvu z’amabateri y’izuba akenshi bwirihira mu myaka 7-10 mu gihe butanga umutekano w’inguvu z’inyuma n’ukwigenga kw’inguvu kwongerekana. Ingingo iherezo iva ku giciro c’amashanyarazi yawe, uburyo ukoresha izuba, n’ingene uha agaciro ukwihangana kw’inguvu birenze inyungu z’amahera zitagira agasembwa.
