Kuchengetedzwa kwesimba rekugara kwave kuwedzera kufarirwa kwezuva remba. Aongororo yazvino yeSunPowerdzemhuri dzinopfuura 1,500 dzakaona kuti inenge 40% yeAmerica inonetseka pamusoro pekudzima kwemagetsi nguva dzose. Pamubvunzo vakapindura vachifunga nezve solar kudzimba dzavo, 70% vakati vakaronga kubatanidza bhatiri rekuchengetedza simba system.
Kunze kwekupa simba rekuchengetedza panguva yekudzima, mabhatiri mazhinji anosanganiswa nehunyanzvi hunobvumira kuronga zvine hungwaru kupinza uye kutumira kunze kwesimba. Chinangwa ndechekuwedzera kukosha kwesolar system yemumba. Uye, mamwe mabhatiri akagadziridzwa kuti abatanidze mota yemagetsi charger.
Chirevo chakacherekedza kukwira kwakanyanya muvatengi vanoratidza kufarira kuchengetedza kuitira kuti vazviwanire chizvarwa chezuva, zvichiratidza kutiyakadzikira net metering ratesvari kurambidza kutengeswa kunze kwenyika kwemagetsi emuno, akachena. Vanenge 40% yevatengi vakashuma kuzvipa sechikonzero chekutora dura rekuchengetedza, kubva pasi pe20% muna 2022. Simba rekuchengetedza rekudzima uye kuchengetedza pamitengo yezvishandiso zvakanyorwawo sezvikonzero zvepamusoro zvekusanganisira kuchengetedza kwesimba mune quote.
Mabatirwo emabhatiri mumapurojekiti ekugara ezuva akakwira zvishoma muna 2020 ne8.1% yenzvimbo dzekugara dzesolar dzakasungirirwa mabhatiri, sekureva kwaLawrence Berkeley National Laboratory, uye muna 2022 chiyero ichi chakakwira neinopfuura 17%.
Hupenyu hwebhatiri
Nguva dzewaranti dzinogona kupa kutarisisa muisimisi uye tarisiro yemugadziri wehupenyu hwebhatiri. Nguva dzewaranti dzakajairika dzinowanzotenderedza makore gumi. ThewarantiyeEnphase IQ Battery, semuenzaniso, inopera pamakore gumi kana mazana manomwe nemazana matatu, chero chinotanga kuitika.
Solar installer Sunrunakadaromabhatiri anogona kugara chero pakati pe5-15 makore. Izvi zvinoreva kuti kutsiva kungangodiwa mukati memakore makumi maviri nemakumi matatu ehupenyu hwezuva.
Hupenyu hwebhatiri hunonyanya kufambiswa nemaitiro ekushandisa. Sezvinoratidzwa ne LG uye Tesla chigadzirwa waranti, zvikumbaridzo zve 60% kana 70% simba zvinotenderwa kuburikidza nehumwe nhamba yekuchaja kutenderera.
Mamiriro maviri ekushandisa anotyaira uku kudzikisira: kuwandisa uye trickle charge,akadaro Faraday Institute. Overcharge chiito chekusaidzira ikozvino mubhatiri rakazara. Kuita izvi kunogona kuita kuti iwedzere kupisa, kana kutokwanisa kubata moto.
Trickle charge inosanganisira maitiro ekuti bhatiri rinogara richichajwa kusvika 100%, uye kurasikirwa kunoitika. Iyo bounce iri pakati pe100% uye ingori pasi pe100% inogona kusimudza tembiricha yemukati, kuderedza kugona uye hupenyu hwese.
Chimwe chinokonzera kukanganisa nekufamba kwenguva kurasikirwa kwefoni lithium-ion mubhatiri, akadaro Faraday. Side reactions mubhatiri inogona kuteya yemahara inoshandiswa lithium, nekudaro ichidzikisa huwandu zvishoma nezvishoma.
Nepo tembiricha inotonhora inogona kumisa lithium-ion bhatiri kubva pakuita, hainyatso kusvibisa bhatiri kana kupfupisa hupenyu hwayo hunoshanda. Hupenyu hwese hwebhatiri, zvisinei, hwakadzikira pakupisa kwakanyanya, akadaro Faraday. Izvi zvinodaro nekuti maelectrolyte anogara pakati pemaelectrodes anoputsika pane tembiricha dzakakwirira, zvichiita kuti bhatiri risakure simba raro reLi-ion shuttling. Izvi zvinogona kuderedza huwandu hweLi-ion iyo electrode inogona kugamuchira muchimiro chayo, ichibvisa iyo lithium-ion bhatiri kugona.
Maintenance
Zvinokurudzirwa neNational Renewable Energy Laboratory (NREL) kuisa bhatiri munzvimbo inotonhorera, yakaoma, zviri nani garaji, uko kukanganisa kwemoto (kutyisidzira kudiki, asi kusiri zero) inogona kuderedzwa. Mabhatiri nezvikamu zvakaatenderedza zvinofanirwa kuve nenzvimbo yakafanira kubvumira kutonhora, uye kugara uchitarisa kugadzirisa kunogona kubatsira mukuona kushanda kwakakwana.
NREL yakataura kuti pese pazvinogoneka, dzivirira kudzokororwa kwakadzika kwemabhatiri, sezvo zvakanyanya kuburitswa, zvinoita hupfupi hupenyu hwese. Kana bhatiri repamba rikadzingwa zvakadzika mazuva ese, ingave nguva yekuwedzera saizi yebhangi rebhangi.
Mabhatiri akateedzana anofanirwa kuchengetwa pamutengo mumwe chete, akadaro NREL. Kunyangwe bhatiri rese rebhatiri richigona kuratidza chaji ye24 volts, panogona kuve nemagetsi akasiyana pakati pemabhatiri, izvo zvisinganyanyi kubatsira kuchengetedza sisitimu yese nekufamba kwenguva. Pamusoro pezvo, NREL yakakurudzira kuti iyo chaiyo voltage seti mapoinzi aisirwe majaja uye ma charger controller, sekutemerwa nemugadziri.
Kuongorora kunofanirwa kuitika kazhinji, zvakare, akadaro NREL. Zvimwe zvinhu zvekutarisa zvinosanganisira kuvuza (kuvaka kunze kwebhatiri), mazinga akakodzera emvura, uye yakaenzana voltage. NREL yakati mugadziri wega wega webhatiri anogona kunge aine mamwe kurudziro, saka kutarisa kuchengetedza uye mapepa edatha pabhatiri inzira yakanaka.
