Ugcino lwebhetri-Isebenza njani
Inkqubo yelanga yePV iguqula ukukhanya kwelanga kube ngumbane osetyenziselwa ngokuzenzekelayo ukutshaja isixokelelwano sokugcina ibhetri kwaye unike amandla ngokuthe ngqo ipropathi, kunye naluphi na ugqithiso olubuyiselwa kwigridi.Nayiphi na
Ukusilela kwamandla, okufana namaxesha okusebenzisa kakhulu okanye ebusuku, kunikezelwa yibhetri ekuqaleni emva koko kongezwa ngumboneleli wakho wamandla ukuba ibhetri iyaphelelwa okanye izaliswe yimfuno.
I-Solar PV isebenza ekukhanyeni, kungekhona ubushushu, ngoko ke nokuba imini ibonakala ibanda, ukuba kukho ukukhanya inkqubo iya kuvelisa umbane, iinkqubo ze-PV ziya kuvelisa umbane unyaka wonke.
Ukusetyenziswa okuqhelekileyo kwamandla e-PV aveliswa yi-50%, kodwa ngokugcinwa kwebhetri, ukusetyenziswa kunokuba ngama-85% okanye ngaphezulu.
Ngenxa yobukhulu kunye nobunzima beebhetri, bahlala bema phantsi kwaye bakhuselekile kwiindonga.Oku kuthetha ukuba zezona zikufanelekela ukufakela kwigaraji encanyathiselweyo okanye indawo yohlobo olufanayo, kodwa iindawo ezizezinye ezifana neendawo eziphezulu zinokuqwalaselwa xa kusetyenziswa izixhobo ezithile.
Iinkqubo zogcino lwebhetri azinampembelelo kuMxholo kwingeniso yoMrhumo njengoko zisebenza kuphela njengendawo yokugcina umbane yethutyana oza kusetyenziswa kwaye ulinganiswe ngemitha ngaphandle kwamaxesha okuvelisa.Ukongeza, njengoko umbane othunyelwa ngaphandle ungabalwanga, kodwa ubalwa njenge-50% yesizukulwana, le ngeniso iya kuhlala ingachaphazeleki.
Isigama
I-Watts kunye ne-kWh - I-watt yiyunithi yamandla esetyenziselwa ukuvakalisa isantya sokudluliselwa kwamandla ngokubhekiselele kwixesha.Okukhona uphezulu umbane wento kokukhona kusetyenziswa umbane ngakumbi.A
i-kilowatt hour (kWh) li-1000 leewatts zamandla asetyenziswayo/aveliswa rhoqo kangangeyure.I-kWh isoloko iboniswa “njengeyunithi” yombane ngababoneleli bombane.
Ukutshaja / ukukhupha umthamo - Isantya apho umbane unokuhlawuliswa kwibhetri okanye ukhutshwe kuyo ukuya kumthwalo.Eli xabiso lidla ngokumelwa kwii-watts, xa liphezulu i-wattage lisebenza ngakumbi ekuboneleleni umbane kwipropati.
Umjikelo wokutshaja - Inkqubo yokutshaja ibhetri kwaye uyikhuphe njengoko kufuneka kumthwalo.Intlawulo epheleleyo kunye nokukhutshwa kubonisa umjikelo, ixesha lokuphila kwebhetri lihlala libalwa kwimijikelezo yentlawulo.Ubomi bebhetri buya kwandiswa ngokuqinisekisa ukuba ibhetri isebenzisa uluhlu olupheleleyo lomjikelo.
Ubunzulu bokukhutshwa - Umthamo wokugcina ibhetri umelwe kwi-kWh, nangona kunjalo awukwazi ukukhupha onke amandla agcinwe.Ubunzulu bokukhutshwa (DOD) yipesenti yokugcina ekhoyo ukuze isetyenziswe.Ibhetri ye-10kWh ene-80% ye-DOD iya kuba ne-8kWh yamandla asebenzisekayo.
Zonke izisombululo ze-YIY Ltd zibonelela ngokusetyenziswa kweebhetri zeLithium Ion kune-Lead Acid.Oku kungenxa yokuba iibhetri zeLithium zezona zixineneyo zamandla (amandla/isithuba esithathiweyo), ziye zaphucuka imijikelo kwaye zinobunzulu bokukhutshwa okungaphezulu kwe-80% kune-50% ye-asidi yelothe.
Ezona nkqubo zisebenzayo ziphezulu, Umthamo wokukhupha (>3kW), imijikelo yokuTshaja (>4000), uMmandla wokuGcina (>5kWh) kunye nobuNzulu bokukhupha (>80%
Ugcino lwebhetri vs Ugcino
Ukugcinwa kwebhetri kumxholo weenkqubo zasekhaya zeSolar PV, yinkqubo yokugcina okwethutyana umbane ovelisiweyo ngamaxesha ogqithiso, oza kusetyenziswa ngamaxesha.
xa ukuvelisa kungaphantsi kombane osetyenziswayo, njengasebusuku.Inkqubo isoloko ixhunyiwe kwigridi kwaye iibhetri zenzelwe ukuba zihlawulwe rhoqo kwaye zikhutshwe (iiCycles).Ugcino lwebhetri luvumela ukusetyenziswa okunexabiso eliphezulu kwamandla avelisiweyo.
Inkqubo yokugcina ibhetri yenza ukuba kusetyenziswe umbane ogciniweyo xa kukho ukunqunyulwa kombane.
Nje ukuba isixokelelwano sihlulwe kwigridi sinokuvulwa ukunika amandla ikhaya.
Nangona kunjalo, njengoko imveliso evela kwibhetri ikhawulelwe ngumthamo wayo wokukhupha, kucetyiswa kakhulu ukwahlula iisekethe zokusetyenziswa okuphezulu ngaphakathi kwepropathi ukuthintela ukulayisha ngaphezulu.
Iibhetri ezigciniweyo zenzelwe ukugcina umbane ixesha elide.
Xa kuthelekiswa nokuphindaphindeka kokusilela kwegridi, kunqabile kakhulu kubathengi ukuba bakhethe ukugcina ugcino oluvunyiweyo ngenxa yemilinganiselo eyongezelelweyo efunekayo.
