Njengoba umhlaba uqaphela ukubaluleka kwamandla avuselelekayo, amandla elanga abe enye indlela ethandwayo kugesi wendabuko. Lapho uhlola izinketho zamandla elanga, amagama amabili avame ukuvela: amasistimu elanga e-on-grid kanyeamasistimu elanga angaphandle kwegridi. Ukuqonda umehluko oyisisekelo phakathi kwalezi zinhlelo ezimbili kubalulekile ekwenzeni isinqumo esinolwazi mayelana nezidingo zakho zamandla elanga. Kule bhulogi, sizohlola umehluko phakathi kwamasistimu elanga akugridi nangaphandle kwegridi futhi sikhanyisele ngezinzuzo zayo ngayinye.
Isistimu yelanga ekugridi:
Amasistimu elanga akugridi axhunywe ngqo kugridi yensiza yendawo. Lezi zinhlelo zisebenzisa ama-solar panel ukuze ziguqule ukukhanya kwelanga kube ugesi, obese ufakwa kugridi. Ugesi okhiqizwayo ungasetshenziswa ukunika amandla ikhaya lakho noma ibhizinisi, noma amandla amaningi angabuyiselwa kugridi. Lokhu kufinyelelwa ngokusebenzisa i-net metering noma isivumelwano se-feed-in tariff, lapho uthola khona amakhredithi noma isinxephezelo sezezimali esisekelwe emandleni angaphezu kwamandla akhiqizwa isistimu.
Izinzuzo zamasistimu elanga akugridi:
1. Ukusebenza Kwezindleko: Amasistimu elanga akugridi ngokuvamile anezindleko ezingcono kunezinhlelo ezingekho kugridi, ngokuyinhloko ngenxa yokuthi aqeda isidingo semishini yokugcina amandla (amabhethri). Lokhu kubenza babe inketho ekhangayo kulabo abafuna ukunciphisa izikweletu zabo zamandla ngaphandle kokufaka izindleko ezinkulu zangaphambili.
2. Ukunikezwa kwamandla angenazihibe: Ngesistimu sonozungezilanga ekugridi, ungathembela kugridi ukuze uthole amandla ngezikhathi lapho amaphaneli akho elanga engakwazi ukukhiqiza amandla anele, njengasebusuku noma ngezinsuku eziguqubele. Lokhu kuqinisekisa ukuthi uthola ugesi ongaphazamiseki, oqhubekayo.
3. Izinzuzo zemvelo: Ngokuphehla amandla elanga, amasistimu elanga akugridi asiza ukwehlisa isidingo sisonke samafutha ezinsalela futhi asize ekudaleni indawo ehlanzekile, neluhlaza.
Isistimu yelanga engaphandle kwegridi:
Amasistimu elanga angaphandle kwegridi, aphinde abizwe ngokuthi amasistimu azimele wodwa, azimele kugridi yensiza yendawo. Lawa masistimu ngokuvamile ahlanganisa amaphaneli elanga, izilawuli zokushaja, amabhethri, nama-inverter. Amaphaneli elanga aguqula ukukhanya kwelanga kube ugesi, ogcinwa kumabhethri ukuze unike amandla ikhaya lakho noma ibhizinisi.
Izinzuzo zamasistimu elanga angaphandle kwegridi:
1. Ukuzimela Kwamandla: Amasistimu angaphandle kwegridi ahlinzeka ngokuzimela okuphelele kwamandla, okukuvumela ukuthi ukhiqize futhi usebenzise ugesi ngaphandle kokuthembela kugridi. Lokhu kubenza babe ukukhetha okuhle kakhulu ezindaweni ezikude noma izindawo ezinokufinyelela kwegridi okulinganiselwe noma okungathembekile.
2. Ukunikezwa kwamandla ngesikhathi sokuhluleka kwegridi: Ngesistimu ye-off-grid, ngeke uhlangabezane nanoma yikuphi ukuphela kukagesi phakathi nokuhluleka kwegridi njengoba isistimu isebenza ngokuzimela.
3. Ukusimama Kwemvelo: Amasistimu angaphandle kwegridi ayanele ngokwawo, asiza ukunciphisa ukukhishwa kwekhabhoni nokuthembela emithonjeni yamandla engavuseleleki.
Ekuphetheni
Lapho unquma ukuthi uzohamba yini nesistimu yelanga ekugridi noma engaphandle kwegridi, kubalulekile ukucabangela indawo yakho, izidingo zamandla, kanye nesabelomali. Amasistimu ahlanganiswe negridi alungele izindawo zasemadolobheni ezinokufinyelela okuthembekile kwegridi kanye nezindawo ezifuna izinzuzo zezomnotho nge-net metering. Ngakolunye uhlangothi, amasistimu angaphandle kwegridi, anikeza ukuzimela kwamandla futhi afanele izindawo ezikude noma abantu ababeka phambili ukwanelisa ukuzimela. Ngokuqonda umehluko oyinhloko phakathi kwalezi zinhlelo, ungenza izinqumo ezinolwazi ezihambisana nezidingo zakho zamandla kanye nemigomo yesikhathi esizayo. Khumbula, noma ngabe ukhetha luphi uhlelo, amandla elanga ayisitebhisi esibheke ekusaseni elisimeme.
Uma unentshisekelo yentengo yesistimu yelanga yegridi, wamukelekile ukuthintana neRadiance kuFunda kabanzi.
