I-solar photovoltaiciziteshi zikagesi zihlukeneamasistimu angaphandle kwegridi (azimele).kanye nezinhlelo ezixhunywe kugridi, futhi manje ngizokutshela umehluko phakathi kwalokhu okubili: Lapho abasebenzisi bekhetha ukufaka iziteshi zamandla elanga le-photovoltaic, kufanele baqale baqinisekise ukusetshenziswa kweziteshi zamandla ze-solar photovoltaic ezingaphandle kwegridi noma iziteshi zamandla elanga ze-solar photovoltaic ezixhunywe kugridi. , ukusetshenziswa kwemisebenzi emibili akufani neze, yebo, ukwakheka kweziteshi zamandla ze-solar photovoltaic akufani, izindleko nazo zihluke kakhulu.
(1)Ngaphandle kwegridiIsiteshi samandla elanga se-photovoltaic, esaziwa nangokuthi isiteshi samandla esizimele se-photovoltaic, siwuhlelo olungancikile kugridi yamandla futhi lusebenza ngokuzimela. Ikakhulukazi yakhiwe ngamaphaneli we-solar photovoltaic, amabhethri okugcina amandla, izilawuli zokushaja nokukhipha, ama-inverters nezinye izingxenye. Ugesi okhishwa iphaneli yokuphehla amandla elanga ye-photovoltaic ugeleza ngqo ebhethrini futhi ugcinwe. Uma kudingekile ukuze kuhlinzekwe amandla kagesi, amandla akhona ebhethri ageleza ku-inverter futhi aguqulelwe ku-220V alternating current, okuwumjikelezo ophindaphindayo wokushaja kanye nenqubo yokukhipha. Lolu hlobo lwesiteshi samandla elanga se-photovoltaic lusetshenziswa kakhulu ngoba alunqunyelwe yisifunda. Ingafakwa futhi isetshenziswe nomaphi lapho ilanga likhanya khona. Ngakho-ke, ifaneleka kakhulu ezindaweni ezikude ezingenawo igridi kagesi, iziqhingi ezingazodwa, izikebhe zokudoba, izisekelo zokuzalanisa ngaphandle, futhi ingasetshenziswa njengemishini yokuphehla ugesi ezimeni eziphuthumayo ezindaweni ezivame ukucisha ugesi.
Iziteshi zamandla elanga eziphuma kugridi ze-photovoltaic zenza u-30-50% wezindleko zesistimu yokukhiqiza ngoba kufanele zifakwe amabhethri. Futhi impilo yesevisi yebhethri ngokuvamile ineminyaka engu-3-5, ngemva kwalokho kufanele ishintshwe, okwandisa izindleko zokusetshenziswa. Uma sikhuluma ngokomnotho, kunzima ukuthola izinhlobonhlobo zokukhuthazwa nokusetshenziswa, ngakho-ke akufanelekile ukusetshenziswa ezindaweni lapho ugesi ulungele khona.
Kodwa-ke, iyakwazi ukusebenziseka okuqinile ezindlini ezisezindaweni ezingenawo igridi kagesi noma ukucisha kukagesi njalo. Ikakhulukazi ukuze uxazulule inkinga yokukhanyisa lapho ukwehluleka kwamandla, ungasebenzisa izibani zokulondoloza amandla e-DC, eziwusizo kakhulu. Ngakho-ke, iziteshi zamandla elanga ze-off-grid photovoltaic zisetshenziselwa ngokukhethekile ezindaweni ezingagudluki noma izindawo lapho ugesi enqamuka njalo.
(2)Igridi-ixhunyiweIsiteshi samandla elanga i-photovoltaic sisho ukuthi kufanele sixhunywe kugridi yamandla kagesi womphakathi, okusho ukuthi isiteshi sikagesi se-solar photovoltaic, igridi kagesi wasendlini kanye negridi yamandla omphakathi kuxhunywe ndawonye. Lena isistimu yamandla elanga e-photovoltaic okumele incike kugridi yamandla ekhona ukuze isebenze. Ikakhulukazi yakhiwe iphaneli yamandla elanga ye-photovoltaic kanye ne-inverter, iphaneli yamandla elanga ye-photovoltaic eguqulwa ngokuqondile ibe yi-220V-380V yi-inverter
Ukushintshana kwamandla nakho kusetshenziselwa ukuphehla izinto zikagesi zasendlini. Lapho izitshalo zelanga ezisophahleni zikhiqiza ugesi omningi kunokusetshenziswa izinto zikagesi, okungaphezu kwalokho kuthunyelwa kugridi yomphakathi. Lapho ukukhishwa kwesiteshi samandla se-photovoltaic sasekhaya kungakwazi ukuhlangabezana nezidingo zemishini yasendlini, igcwaliswa ngokuzenzakalelayo kusuka kugridi. Yonke le nqubo ilawulwa ngobuhlakani, akukho switch yomuntu evuliwe noma evaliwe.
Uma unentshisekelo kulo mkhiqizo, ungachofoza ekhoneni elingezansi kwesokudla, sizokuthinta ngokushesha ngangokunokwenzeka.
