I-photovoltaic yelangaizitishi zamandla zahlulwe zibeiinkqubo ezingasebenzi kwigridi (ezizimeleyo)kunye neenkqubo ezidityaniswe negridi, kwaye ngoku ndiza kukuxelela umahluko phakathi kwezi zimbini: Xa abasebenzisi bekhetha ukufaka izitishi zamandla ze-photovoltaic zelanga, kufuneka baqale baqinisekise ukusetyenziswa kwezitishi zamandla ze-photovoltaic zelanga ezingaphandle kwegridi okanye izitishi zamandla ze-photovoltaic zelanga ezidityaniswe negridi, ukusetyenziswa kwezi misebenzi mibini akufani ngokupheleleyo, ewe, ukwakheka kwezitishi zamandla ze-photovoltaic zelanga akufani, ixabiso nalo lahlukile kakhulu.
(1)Ngaphandle kwegridiIsikhululo samandla se-photovoltaic selanga, esaziwa ngokuba sisikhululo samandla se-photovoltaic esizimeleyo, yinkqubo engaxhomekekanga kwigridi yamandla kwaye isebenza ngokuzimeleyo. Iquka ikakhulu iiphaneli zamandla elanga ze-photovoltaic, iibhetri zokugcina amandla, abalawuli betshaja kunye nokukhupha, ii-inverters kunye nezinye izinto. Umbane okhutshwa yiphaneli yokuvelisa amandla elanga ye-photovoltaic ungena ngqo kwibhetri kwaye ugcinwa. Xa kufuneka ukubonelela ngombane, umbane othe ngqo kwibhetri ungena kwi-inverter kwaye uguqulwa ube ngumbane otshintshanayo we-220V, ongumjikelo ophindaphindayo wenkqubo yokutshaja kunye nokukhupha. Olu hlobo lwesikhululo samandla elanga se-photovoltaic sisetyenziswa kakhulu kuba asithintelwanga ngummandla. Singafakwa kwaye sisetyenziswe naphi na apho ilanga likhanya khona. Ke ngoko, sifanelekile kakhulu kwiindawo ezikude ezingenagridi yamandla, iziqithi ezizimeleyo, iinqanawa zokuloba, iziseko zokuzalela zangaphandle, kwaye singasetyenziswa njengezixhobo zokuvelisa umbane ezingxamisekileyo kwiindawo ezinqamka rhoqo umbane.
Izikhululo zamandla zelanga ezisebenzisa i-photovoltaic ezingaphandle kwegridi zithatha i-30-50% yeendleko zenkqubo yokuvelisa kuba kufuneka zixhotyiswe ngeebhetri. Kwaye ubomi benkonzo yebhetri buhlala bukwiminyaka emi-3-5, emva koko kufuneka itshintshwe, nto leyo enyusa iindleko zokusetyenziswa. Ngokwezoqoqosho, kunzima ukufumana uluhlu olubanzi lokukhuthaza nokusetyenziswa, ngoko ke ayifanelekanga ukusetyenziswa kwiindawo apho umbane ulula khona.
Nangona kunjalo, iyasebenza kakhulu kumakhaya akwiindawo ezingenayo igridi yombane okanye umbane ocinywa rhoqo. Ingakumbi ukuze usombulule ingxaki yokukhanyisa xa umbane ucinywa, ungasebenzisa izibane zeDC ezonga umbane, eziluncedo kakhulu. Ke ngoko, izitishi zamandla elanga ezisebenzisa i-photovoltaic ezingaphandle kwegridi zisetyenziselwa ngokukodwa kwiindawo ezingagayiyo okanye kwiindawo apho umbane ucinywa rhoqo.
(2)Iqhagamshelwe kwigridiIsikhululo samandla elanga se-photovoltaic sithetha ukuba kufuneka siqhagamshelwe kwigridi yamandla kawonke-wonke, oko kuthetha ukuba isikhululo samandla se-photovoltaic selanga, igridi yamandla yasekhaya kunye negridi yamandla kawonke-wonke zidibene. Le yinkqubo yamandla elanga ye-photovoltaic ekufuneka ixhomekeke kwigridi yamandla ekhoyo ukuze isebenze. Ngokuyintloko yenziwe yiphaneli yamandla elanga ye-photovoltaic kunye ne-inverter, iphaneli yamandla elanga ye-photovoltaic iguqulwe ngokuthe ngqo kwi-220V-380V yi-inverter.
Umbane otshintshiselanayo usetyenziswa nasekunikezeni amandla izixhobo zasekhaya. Xa izityalo zelanga eziphezu kophahla zivelisa umbane omninzi kunosetyenziswa zizixhobo, loo mbane ugqithisileyo uthunyelwa kwigridi kawonke-wonke. Xa imveliso yesikhululo samandla se-photovoltaic sasekhaya ingakwazi ukuhlangabezana neemfuno zezixhobo zasekhaya, igcwaliswa ngokuzenzekelayo kwigridi. Yonke inkqubo ilawulwa ngobuchule, kungekho switshi okanye ivaliwe ngumntu.
Ukuba unomdla kule mveliso, ungacofa kwikona esezantsi ngasekunene, siza kuqhagamshelana nawe ngokukhawuleza.
