I-photovoltaic yelangaiziteshi zikagesi zihlukaniswe ngezigabaizinhlelo ezingaphandle kwegridi (ezizimele)kanye nezinhlelo ezixhunywe kugridi, futhi manje ngizokutshela umehluko phakathi kwalokhu okubili: Uma abasebenzisi bekhetha ukufaka iziteshi zamandla ze-photovoltaic zelanga, kumele baqale baqinisekise ukusetshenziswa kweziteshi zamandla ze-photovoltaic zelanga ezingaphandle kwegridi noma iziteshi zamandla ze-photovoltaic zelanga ezixhunywe kugridi, ukusetshenziswa kwale misebenzi emibili akufani nhlobo, vele, ukwakheka kweziteshi zamandla ze-photovoltaic zelanga akufani, izindleko nazo zihlukile kakhulu.
(1)Ngaphandle kwegridiIsiteshi sikagesi se-photovoltaic selanga, esaziwa nangokuthi isiteshi sikagesi se-photovoltaic esizimele, siyisistimu engancikile kugridi yamandla futhi isebenza ngokuzimela. Sakhiwe kakhulu ngamaphaneli kagesi welanga we-photovoltaic, amabhethri okugcina amandla, abalawuli bokushaja nokukhipha, ama-inverter nezinye izingxenye. Ugesi okhishwa yiphaneli yokukhiqizwa kukagesi welanga we-photovoltaic ugeleza ngqo ebhethrini bese ugcinwa. Uma kudingeka ukuze kunikezwe amandla kagesi, ugesi oqondile ebhethri ugeleza nge-inverter bese uguqulwa ube ugesi oshintshashintshayo ongu-220V, okuwumjikelezo ophindaphindayo wenqubo yokushaja nokukhipha. Lolu hlobo lwesiteshi sikagesi selanga se-photovoltaic sisetshenziswa kabanzi ngoba asinqunyelwe yisifunda. Singafakwa futhi sisetshenziswe noma kuphi lapho ilanga likhanya khona. Ngakho-ke, sifaneleka kakhulu ezindaweni ezikude ezingenagridi yamandla, iziqhingi ezihlukanisiwe, izikebhe zokudoba, izisekelo zokuzalela zangaphandle, futhi singasetshenziswa njengemishini yokukhiqizwa kukagesi ephuthumayo ezindaweni ezinqamuka njalo kukagesi.
Iziteshi zamandla elanga ezisebenzisa i-photovoltaic ezingaphandle kwegridi zibiza u-30-50% wezindleko zohlelo lokukhiqiza ngoba kumele zifakwe amabhethri. Futhi impilo yebhethri ngokuvamile iseminyakeni engu-3-5, ngemva kwalokho kufanele ishintshwe, okwandisa izindleko zokusebenzisa. Ngokwezomnotho, kunzima ukuthola ukukhushulwa nokusetshenziswa okubanzi, ngakho-ke akufanele ukusetshenziswa ezindaweni lapho ugesi ulula khona.
Kodwa-ke, inamandla amakhulu emindenini ezindaweni ezingenayo igridi kagesi noma ukucima kukagesi okuvamile. Ikakhulukazi ukuze uxazulule inkinga yokukhanyisa lapho ugesi uphela, ungasebenzisa izibani ze-DC ezonga amandla, eziwusizo kakhulu. Ngakho-ke, iziteshi zikagesi zelanga ze-photovoltaic ezingaphandle kwegridi zisetshenziswa ngqo ezindaweni ezingagayiwe noma ezindaweni ezinqamuka ugesi okuvamile.
(2)Igridi ixhunyiweIsiteshi sikagesi selanga se-photovoltaic sisho ukuthi kumele sixhunywe kugridi kagesi yomphakathi, okusho ukuthi isiteshi sikagesi se-photovoltaic selanga, igridi kagesi yasekhaya kanye negridi kagesi yomphakathi kuxhunywe ndawonye. Lolu uhlelo lukagesi lwelanga lwe-photovoltaic okumele luthembele kugridi kagesi ekhona ukuze lusebenze. Kakhulukazi lwakhiwe yiphaneli kagesi yelanga ye-photovoltaic kanye ne-inverter, iphaneli kagesi yelanga ye-photovoltaic eguqulwa ngqo ibe yi-220V-380V yi-inverter.
Ugesi oshintshashintshayo usetshenziswa futhi ukunika amandla izinto zasekhaya. Lapho izitshalo zelanga eziphezu kophahla zikhiqiza ugesi omningi kunokusetshenziswa kwezinto zasekhaya, okusele kuthunyelwa kugridi yomphakathi. Lapho umphumela wesiteshi sikagesi se-photovoltaic sasekhaya ungahlangabezani nezidingo zezinto zasekhaya, ugcwaliswa ngokuzenzakalelayo kusuka kugridi. Yonke inqubo ilawulwa ngobuhlakani, ngaphandle kokuvula noma ukuvala komuntu.
Uma unentshisekelo kulo mkhiqizo, ungachofoza ekhoneni elingezansi kwesokudla, sizokuthinta ngokushesha okukhulu.
