Eminyakeni yamuva nje, isidingo sokuphathwa kwamandla ezindlini besilokhu sikhula kancane kancane. Ikakhulukazi ngemva kokuba imindeni ifake amasistimu e-photovoltaic (solar), abasebenzisi abaningi bakhetha ukuguqula amasistimu elanga akhona axhunywe kugridi abe amasistimu okugcina amandla asekhaya ukuze kuthuthukiswe ukusebenza kahle kwamandla nokunciphisa izindleko zikagesi. Lokhu kuguqulwa akugcini nje ngokukhuphula ukuzisebenzisela ugesi kodwa futhi kuthuthukisa ukuzimela kwamandla ekhaya.
1. Luyini Uhlelo Lokugcina Amandla Ekhaya?
Isistimu yokugcina amandla yasekhaya iyisisetshenziswa esiklanyelwe ngokukhethekile ukusetshenziswa kwasekhaya, ngokuvamile esihlanganiswe nesistimu ye-photovoltaic yasekhaya. Umsebenzi wayo oyinhloko uwukugcina ugesi oweqile okhiqizwa amandla elanga kumabhethri ukuze asetshenziswe ebusuku noma ngezikhathi zenani eliphakeme kakhulu likagesi, okunciphisa isidingo sokuthenga ugesi kugridi. Uhlelo luqukethe amaphaneli e-photovoltaic, amabhethri okugcina, ama-inverters, nezinye izingxenye ezilawula ngobuhlakani ukuhlinzekwa nokugcinwa kukagesi ngokusekelwe ekusetshenzisweni kwasekhaya.
2. Kungani Abasebenzisi Bengafaka Amasistimu Okugcina Amandla?
- Ukonga Izikweletu zikagesi: Isidingo sikagesi wasekhaya ngokuvamile siphakama kakhulu ebusuku, kuyilapho amasistimu e-photovoltaic ekhiqiza amandla ikakhulukazi emini, okudala ukungafani ngesikhathi. Ngokufaka isistimu yokugcina amandla, ugesi oweqile okhiqizwa emini ungagcinwa futhi usetshenziswe ebusuku, ukugwema amanani entengo kagesi aphezulu phakathi namahora aphakeme kakhulu.
- Umehluko Wamanani Kagesi: Izintengo zikagesi ziyahlukahluka usuku lonke, ngamanani aphezulu ngokuvamile ebusuku futhi amanani aphansi phakathi nosuku. Amasistimu okugcina amandla angashaja ngezikhathi zokungasebenzi kakhulu (isb, ebusuku noma lapho libalele) ukuze kugwenywe ukuthenga ugesi kugridi ngezikhathi zamanani aphezulu.
3. Iyini I-Gridi-Connected Household Solar System?
Isistimu yelanga exhunywe kugridi iyisethaphu lapho ugesi okhiqizwa amaphaneli elanga asendlini ufakwa kugridi. Ingasebenza ngezindlela ezimbili:
- Imodi Yokuthekelisa Yegridi Egcwele: Wonke ugesi okhiqizwa uhlelo lwe-photovoltaic ufakwa kugridi, futhi abasebenzisi bathola imali engenayo ngokusekelwe enanini likagesi abalithumela kugridi.
- Ukuzisebenzisela Imodi Yokuthekelisa Ngokweqile: Uhlelo lwe-photovoltaic lubeka phambili ukuhlinzeka ngezidingo zikagesi zasekhaya, nanoma yimaphi amandla angaphezu kwamandla athunyelwa kugridi. Lokhu kuvumela abasebenzisi ukuthi basebenzise ugesi futhi bathole imali engenayo ngokuthengisa amandla angaphezulu.
4. Yiziphi Izinhlelo Zelanga Ezixhunywe Igridi Ezifanele Ukuguqulelwa Ezinhlelweni Zokugcina Amandla?
Uma uhlelo lusebenza kuImodi Yokuthekelisa Yegridi Egcwele, ukuyiguqulela ohlelweni lokugcina amandla kunzima kakhulu ngenxa yezizathu ezilandelayo:
- Imali Engenayo Ezinzile Evela Kumodi Yokuthekelisa Yegridi Egcwele: Abasebenzisi bathola imali engenayo engashintshi ngokuthengisa ugesi, ngakho-ke kunesikhuthazo esincane sokushintsha uhlelo.
- Uxhumano Lwegridi Eqondile: Kule modi, i-photovoltaic inverter ixhunywe ngokuqondile kugridi futhi ayidluli emithwalweni yasendlini. Ngisho noma isistimu yokugcina amandla ingeziwe, amandla engeziwe azogcinwa futhi afakwe kugridi, angasetshenziselwa ukuzisebenzisela wona.
Ngokuphambene, amasistimu axhunywe kugridi asebenza ku-Ukuzisebenzisela Imodi Yokuthekelisa Ngokweqilezifaneleka kakhulu ukuguqulelwa kumasistimu okugcina amandla. Ngokungeza isitoreji, abasebenzisi bangagcina ugesi okhiqizwa emini futhi bawusebenzise ebusuku noma phakathi nokucisha kukagesi, okwandisa ingxenye yamandla elanga asetshenziswa yindlu.
5. Ukuguqulwa kanye Nezimiso Zokusebenza ze-Coupled Photovoltaic + Energy Storage System
- Isingeniso Sesistimu: Isistimu yokulondoloza amandla ehlanganisiwe ye-photovoltaic + ngokuvamile iqukethe amaphaneli e-photovoltaic, ama-inverter axhunywe kugridi, amabhethri okugcina, ama-inverters okugcina amandla ahlanganiswe ne-AC, amamitha ahlakaniphile, nezinye izingxenye. Lolu hlelo luguqula amandla e-AC akhiqizwe isistimu ye-photovoltaic abe amandla e-DC ukuze agcinwe kumabhethri kusetshenziswa i-inverter.
- Ukusebenza Logic:
- Emini: Amandla elanga aqale anikeze umthwalo wasendlini, bese eshaja ibhethri, futhi noma yimuphi ugesi osalayo ungafakwa kugridi.
- Ebusuku: Ibhethri liyaphuma ukuze linikeze umthwalo wasendlini, nanoma yikuphi ukushoda okulekelelwa igridi.
- Ukunqamuka kukagesi: Ngesikhathi sokucisha kwegridi, ibhethri linikeza amandla kuphela emithwalweni engaphandle kwegridi futhi ayikwazi ukunikeza amandla emithwalweni exhunywe kugridi.
- Izici Zesistimu:
- Ukuguqulwa Kwezindleko Eziphansi: Izinhlelo ezikhona ezixhunywe kugridi ze-photovoltaic zingaguqulwa kalula zibe izinhlelo zokugcina amandla ezinezindleko eziphansi zokutshala imali.
- Ukunikezwa Amandla Ngesikhathi Sokucisha Igridi: Ngisho nalapho ugesi wegridi uhluleka, isistimu yokugcina amandla ingaqhubeka nokuhlinzeka ngamandla endlini, iqinisekise ukuvikeleka kwamandla.
- Ukuhambisana Okuphezulu: Uhlelo luhambisana namasistimu elanga axhunywe kugridi avela kubakhiqizi abahlukene, okwenza lusebenze kabanzi.
Isiphetho
Ngokuguqula isistimu ye-photovoltaic exhunywe kugridi yasendlini ibe isistimu yokugcina amandla e-photovoltaic + ehlanganisiwe, abasebenzisi bangakwazi ukuzuza ukuzisebenzisela okukhulu kukagesi, banciphise ukuncika kugesi wegridi, futhi baqinisekise ukunikezwa kwamandla ngesikhathi sokucima kwegridi. Lokhu kuguqulwa kwezindleko eziphansi kwenza amakhaya akwazi ukusebenzisa kangcono imithombo yamandla elanga futhi azuze ukonga okukhulu ezikweletini zikagesi.
