Isitoreji Sebhethri - Sisebenza Kanjani
Isistimu ye-solar PV iguqula ukukhanya kwelanga kube ugesi osetshenziswa ngokuzenzakalelayo ukushaja isistimu yokugcina ibhethri futhi inike amandla impahla ngokuqondile, nanoma yikuphi okudlulele okubuyiselwe emuva kugridi.Noma yikuphi
ukuntuleka kwamandla, njengezikhathi zokusetshenziswa kakhulu noma ebusuku, kunikezwa ibhethri ekuqaleni bese igcwaliswa ngumnikezeli wakho wamandla uma ibhethri liphelelwa amandla noma ligcwala kakhulu ngokufunwa.
I-Solar PV isebenza ngokukhanya okukhulu, hhayi ukushisa, ngakho-ke ngisho noma usuku lubonakala lubanda, uma kunokukhanya uhlelo luzobe lukhiqiza ugesi, izinhlelo ze-PV zizokhiqiza ugesi unyaka wonke.
Ukusetshenziswa okuvamile kwamandla e-PV akhiqizwayo ngu-50%, kodwa ngokugcinwa kwebhethri, ukusetshenziswa kungaba ngu-85% noma ngaphezulu.
Ngenxa yobukhulu nesisindo samabhethri, avame ukuma phansi futhi avikelwe ezindongeni.Lokhu kusho ukuthi zikufanele kakhulu ukufakwa egaraji elinamathiselwe noma indawo yohlobo olufanayo, kodwa ezinye izindawo ezifana nezindawo eziphakeme zingacatshangelwa uma kusetshenziswa izinto ezithile.
Amasistimu okugcina amabhethri awanawo umthelela Emalini Yokuphakelayo emalini etholwayo njengoba esebenza njengesitolo sesikhashana sikagesi ozosetshenziswa futhi ulinganiswe ngaphandle kwezikhathi zokuphehla.Ukwengeza, njengoba ugesi othunyelwa kwamanye amazwe ungalinganisiwe, kodwa ubalwa njengama-50% okukhiqiza, le mali engenayo izohlala ingathinteki.
Amagama
I-Watts ne-kWh - I-watt iyiyunithi yamandla asetshenziselwa ukuveza izinga lokudluliswa kwamandla ngokuphathelene nesikhathi.Uma umthamo wento uphezulu kulapho kusetshenziswa khona ugesi omningi.A
ihora le-kilowatt (kWh) amawathi angu-1000 wamandla asetshenziswa/akhiqizwa njalo ihora.I-kWh ivamise ukumelelwa “njengeyunithi” kagesi abahlinzeki bakagesi.
Ikhono lokushaja/lokukhipha - Izinga ugesi ongashajwa ngalo ebhethrini noma uphume kulo ugcwale.Lelivelu livame ukumelwa ngama-watts, lapho i-wattage iphakama yilapho isebenza kahle kakhulu ekunikezeni ugesi endaweni.
Umjikelezo Wokushaja – Inqubo yokushaja ibhethri nokulikhipha njengoba kudingeka ekulayisheni.Ukushaja okuphelele nokukhipha kumelela umjikelezo, ubude besikhathi sebhethri buvame ukubalwa ngemijikelezo yokushajwa.Impilo yebhethri izonwetshwa ngokuqinisekisa ukuthi ibhethri isebenzisa uhla olugcwele lomjikelezo.
Ukujula Kokukhipha - Umthamo wokugcina webhethri umelwe ku-kWh, nokho alikwazi ukukhipha wonke amandla eliwagcinayo.Ukujula Kokukhipha (DOD) iphesenti lesitoreji esitholakalayo ukuze sisetshenziswe.Ibhethri elingu-10kWh elino-80% DOD lizoba namandla angu-8kWh asebenzisekayo.
Zonke izixazululo i-YIY Ltd ihlinzeka ngamabhethri e-Lithium Ion kune-Lead Acid.Lokhu kungenxa yokuthi amabhethri e-Lithium angamandla aminyene kakhulu (amandla/isikhala esithathiwe), anemijikelezo ethuthukisiwe futhi abe nokujula kokukhipha okungaphezu kuka-80% kunokuba ku-50% ku-asidi yomthofu.
Amasistimu asebenza kahle kakhulu anamandla aphezulu, Amandla Okukhipha (>3kW), Imijikelezo Yokushaja (>4000), Amandla Esitoreji (>5kWh) Nokujula Kokukhipha (>80%
Isitoreji Sebhethri vs Isipele
Ukugcinwa kwebhethri kumongo wezinhlelo zasekhaya zeSolar PV, kuyinqubo yokugcina ugesi okhiqiziwe okwesikhashana ezikhathini zokuweqisa, ozosetshenziswa ezikhathini.
lapho ukukhiqiza kungaphansi kokusetshenziswa kukagesi, njengasebusuku.Isistimu ihlale ixhunywe kugridi futhi amabhethri enzelwe ukushajwa njalo futhi akhishwe (Ama-Cycles).Isitoreji sebhethri sinika amandla ukusetshenziswa okungabizi kwamandla akhiqiziwe.
Isistimu yokusekela ibhethri yenza ukuba kusetshenziswe ugesi ogciniwe uma kwenzeka unqanyulwa.
Uma uhlelo seluhlukanisiwe kugridi lungenziwa lusebenze ukuze lunike amandla ikhaya.
Kodwa-ke, njengoba okukhiphayo okuvela ebhethrini kukhawulelwe amandla ayo okukhipha, kunconywa kakhulu ukuhlukanisa amasekhethi okusetshenziswa okuphezulu ngaphakathi kwendawo ukuze kuvinjelwe ukugcwala ngokweqile.
Amabhethri ekhophi yasenqolobaneni aklanyelwe ukugcina ugesi isikhathi eside.
Uma kuqhathaniswa nemvamisa yokuhluleka kwegridi, akuvamile kakhulu kubathengi ukuthi bakhethe ukwenza isipele esinikwe amandla isitoreji ngenxa yezinyathelo ezengeziwe ezidingekayo.
