I-Solar photovoltaicizikhululo zombane zahlulwe zabaiinkqubo ezingekho kwigridi (ezizimeleyo).kunye neenkqubo eziqhagamshelwe kwigridi, kwaye ngoku ndiya kukuxelela umahluko phakathi kwezi zimbini: Xa abasebenzisi bekhetha ukufaka izikhululo zamandla elanga ze-photovoltaic, kufuneka baqale baqinisekise ukusetyenziswa kwezikhululo zamandla ze-solar photovoltaic ezingaphandle kwegridi okanye izikhululo zamandla ze-solar photovoltaic ezixhunyiwe kwigridi. , ukusetyenziswa kwemisebenzi emibini ayifani ngokufanayo, ngokuqinisekileyo, ukubunjwa kwezikhululo zamandla ze-photovoltaic zelanga azifani, iindleko nazo zihluke kakhulu.
(1)Ngaphandle kwegridiIsikhululo samandla elanga se-photovoltaic, esaziwa ngokuba sisikhululo samandla esizimeleyo se-photovoltaic, yinkqubo engathembeli kwigridi yamandla kwaye isebenze ngokuzimeleyo. Ikakhulu iqulethwe ngamapaneli ombane welanga we-photovoltaic, iibhetri zokugcina amandla, izilawuli zokuhlawula kunye nokukhupha, ii-inverters kunye nezinye izinto. Umbane okhutshwe yi-photovoltaic iphaneli yokuvelisa amandla elanga uhamba ngokuthe ngqo kwibhetri kwaye igcinwe. Xa kufuneka unikeze amandla ombane, umbane othe ngqo kwibhetri uhamba nge-inverter kwaye uguqulwa ube ngu-220V otshintshileyo wangoku, oku kumjikelezo ophindaphindiweyo wentlawulo kunye nenkqubo yokukhupha. Olu hlobo lwesikhululo samandla elanga se-photovoltaic sisetyenziswa ngokubanzi kuba alukhawulelwanga ngummandla. Inokufakwa kwaye isetyenziswe naphi na apho ilanga likhanya. Ngoko ke, ifaneleke kakhulu kwiindawo ezikude ngaphandle kwegridi yamandla, iziqithi ezizimeleyo, izikebhe zokuloba, iziseko zokuzalela ngaphandle, kwaye zinokusetyenziswa njengezixhobo zokuvelisa umbane ongxamisekileyo kwiindawo ezinombane rhoqo.
Izikhululo zamandla elanga ze-photovoltaic ngaphandle kwegridi zithatha i-30-50% yeendleko zenkqubo yokuvelisa kuba kufuneka zixhotyiswe ngeebhetri. Kwaye ubomi benkonzo yebhetri ngokuqhelekileyo kwiminyaka eyi-3-5, emva koko kufuneka itshintshwe, eyandisa iindleko zokusetyenziswa. Ukuthetha ngokwezoqoqosho, kunzima ukufumana uluhlu olubanzi lokunyuswa kunye nokusetyenziswa, ngoko akufanelekile ukusetyenziswa kwiindawo apho umbane ulungele.
Nangona kunjalo, iyakwazi ukusebenza ngamandla kumakhaya akwiindawo ezingenawo igridi yamandla okanye ukuphuma kombane rhoqo. Ngokukodwa ukuze kulungiswe ingxaki yokukhanyisa xa ukusilela kombane, ungasebenzisa izibane zokonga amandla eDC, ezisebenzisekayo kakhulu. Ngoko ke, izikhululo zamandla elanga ze-off-grid photovoltaic zisetyenziselwa ngokukodwa kwiindawo ezingenayo i-ungrid okanye iindawo ezinombane rhoqo.
(2)Igridi-iqhagamshelweisikhululo samandla elanga se-photovoltaic sithetha ukuba kufuneka siqhagamshelwe kwigridi yamandla oluntu, nto leyo ethetha ukuba isikhululo sombane wesolar photovoltaic, igridi yombane wekhaya kunye nombane woluntu ziqhagamshelwe kunye. Le yinkqubo yamandla elanga ye-photovoltaic ekufuneka ithembele kwigridi yamandla ekhoyo ukuze isebenze. Ikakhulu yenziwe ngephaneli yamandla elanga ye-photovoltaic kunye ne-inverter, iphaneli yamandla elanga ye-photovoltaic iguqulwe ngokuthe ngqo kwi-220V-380V yi-inverter.
Umsinga otshintshanayo ukwasetyenziselwa umbane kwizixhobo zasekhaya. Xa izityalo zelanga eziphezu kophahla zivelisa umbane ongaphezu kokusetyenziswa kwezixhobo zombane, umbane ongaphezulu uthunyelwa kwigridi yoluntu. Xa imveliso yesikhululo samandla e-photovoltaic yasekhaya ayikwazi ukuhlangabezana neemfuno zezixhobo zendlu, izaliswa ngokuzenzekelayo kwigridi. Yonke le nkqubo ilawulwa ngobukrelekrele, akukho sixhobo somntu sicinywayo okanye sivaliwe.
Ukuba unomdla kule mveliso, unokucofa kwikona esezantsi ekunene, siya kuqhagamshelana nawe ngokukhawuleza.
