Izindleko eziphansi! Amasistimu Ahlanganisa Igridi Yasekhaya Angathuthukiswa abe Amasistimu Okugcina Amandla Wasekhaya

Q1: Yini i-aisistimu yokugcina amandla yasendlini?

Isistimu yokugcina amandla yasendlini yakhelwe abasebenzisi bezindawo zokuhlala futhi ngokuvamile ihlanganiswa nesistimu ye-photovoltaic yasekhaya (PV) ukuze inikeze amandla kagesi ezindlini.

Q2: Kungani abasebenzisi bengeza isitoreji samandla?

Isikhuthazo esikhulu sokwengeza ukugcinwa kwamandla ukonga ezindlekweni zikagesi. Ukusetshenziswa kukagesi ezindaweni zokuhlala kuphakama kakhulu ebusuku, kuyilapho ukukhiqizwa kwe-PV kwenzeka emini, okuholela ekungafanini phakathi kwezikhathi zokukhiqiza nezokusetshenziswa. Isitoreji samandla sisiza abasebenzisi ukuthi bagcine ugesi omningi wasemini ukuze bawusebenzise ebusuku. Ukwengeza, amanani kagesi ayahlukahluka usuku lonke ngenani eliphakeme nelingekho phezulu. Amasistimu okugcina amandla angashaja ngezikhathi zokungasebenzi kakhulu ngegridi noma amaphaneli e-PV futhi achithe ngezikhathi eziphakeme, ngaleyo ndlela agweme izindleko zikagesi eziphakeme ezivela kugridi futhi ehlise ngempumelelo izikweletu zikagesi.

Q3: Iyini isistimu yegridi yasendlini?

Ngokuvamile, amasistimu axhunywe kugridi angahlukaniswa ngamamodi amabili:

• Imodi Yokufaka Okugcwele:Amandla e-PV afakwa kugridi, futhi imali engenayo isekelwe enanini likagesi elifakwe kugridi.
• Ukuzisebenzisa ngokwakho Ngemodi Yokuphakela Okudlulele:Amandla e-PV asetshenziswa ngokuyinhloko ukusetshenziswa kwasekhaya, nanoma yimuphi ugesi oweqile ofakwa kugridi ukuze uthole imali engenayo.

Q4: Iluphi uhlobo lwesistimu yegridi yasendlini efanele ukuguqulelwa ohlelweni lokugcina amandla?Amasistimu asebenzisa ukuzisebenzisela ngemodi yokuphakela ngokweqile afaneleka kakhulu ukuguqulelwa kusistimu yokugcina amandla. Izizathu yilezi:

• Amasistimu emodi yokuphakela ngokugcwele anenani elinqunyiwe lokuthengisa ugesi, anikeza imbuyiselo ezinzile, ngakho ukuguqulwa ngokuvamile akudingekile.
• Kumodi yokuphakelayo egcwele, okukhiphayo kwesiguquli se-PV kuxhunywe ngokuqondile kugridi ngaphandle kokudlula emithwalweni yasendlini. Ngisho nokwengezwa kwesitoreji, ngaphandle kokushintsha izintambo ze-AC, ingagcina amandla e-PV kuphela futhi iwafake kugridi ngezinye izikhathi, ngaphandle kokuvumela ukuzisebenzisa.

I-PV Yasekhaya Ehlanganisiwe + Uhlelo Lokugcina Amandla

Okwamanje, ukuguqula amasistimu ahlanganiswe negridi yasendlini abe amasistimu okugcina amandla kusebenza kakhulu kumasistimu e-PV kusetshenziswa ukuzisebenzisela okunemodi yokuphakela ngokweqile. Uhlelo oluguquliwe lubizwa ngokuthi i-PV yasendlini ehlanganisiwe + uhlelo lokugcina amandla. Isisusa esiyinhloko sokuguqulwa ukuncishiswa kwezibonelelo zikagesi noma imikhawulo yokudayiswa kwamandla ebekwe yizinkampani zamagridi. Abasebenzisi abanamasistimu e-PV yasendlini akhona bangase bacabangele ukwengeza isitoreji samandla ukuze banciphise ukuthengiswa kwamandla emini kanye nokuthengwa kwegridi yasebusuku.

Umdwebo we-PV Yasekhaya Ehlanganisiwe + Uhlelo Lokugcina Amandla

01 Isingeniso SesistimuIsistimu yokugcina amandla ehlanganisiwe ye-PV +, eyaziwa nangokuthi i-AC-coupled PV + uhlelo lokugcina amandla, ngokuvamile iqukethe amamojula e-PV, i-inverter eboshwe ngegridi, amabhethri e-lithium, i-AC-coupled storage inverter, imitha ehlakaniphile, ama-CTs, igridi, imithwalo eboshelwe kugridi, nemithwalo ye-off-grid. Lolu hlelo luvumela amandla e-PV engeziwe ukuthi aguqulelwe ku-AC yi-inverter eboshwe ngegridi bese abe yi-DC ukuze agcinwe ebhethrini ngesiguquli sesitoreji esihlanganiswe ne-AC.

02 Ukusebenza OkunengqondoEmini, amandla e-PV aqale anikeze umthwalo, bese eshaja ibhethri, futhi noma yikuphi okweqile kufakwa kugridi. Ebusuku, ibhethri liyaphuma ukuze linikeze umthwalo, nanoma yikuphi okushodayo okulekelelwa igridi. Esimeni sokucisha kwegridi, ibhethri ye-lithium inika amandla imithwalo engaphandle kwegridi kuphela, futhi imithwalo eboshwe ngegridi ayikwazi ukusetshenziswa. Ukwengeza, uhlelo luvumela abasebenzisi ukuthi bazibekele izikhathi zabo zokushaja nezokushajwa ukuze bahlangabezane nezidingo zabo zikagesi.

03 Izici Zesistimu

1. Izinhlelo ezikhona ze-PV eziboshwe ngegridi zingaguqulelwa kumasistimu okugcina amandla anezindleko eziphansi zokutshala imali.
2. Ihlinzeka ngokuvikelwa kwamandla okuthembekile phakathi nokucisha kwegridi.
3. Ihambisana nezinhlelo ze-PV eziboshwe ngegridi ezivela kubakhiqizi abahlukene.
