Kule mihla, abantu abaninzi bafuna ukudibanisa impompo yobushushu yomthombo womoya kunye nenkqubo yeSolar PV ukonga amandla amaninzi. Ngaphambi koko, makhe sifunde ulwazi malunga nomahluko phakathi kweentlobo zeenkqubo zelanga zePV.
Kukho iintlobo ezintathu ezibalaseleyo zeSolar PV Systems:
Igridi iQhagamshelwe okanye IiNkqubo eziSebenzayo-eziSebenzayo
Iinkqubo ezizimeleyo
IiNkqubo zeHybrid
Masiphonononge ezi ntlobo zintathu zeeNkqubo zePV ngokweenkcukacha:
1. I-Grid-Connected System
Iinkqubo zePV eziqhagamshelwe kwigridi azifuni kugcinwa kwebhetri. Nangona kunjalo, kuhlala kusenzeka ukongeza ibhetri kwisixokelelwano selanga esiqhagamshelwe kwigridi.
(A) IiNkqubo zePV eziQhagamshelwe ngeGridi ngaphandle kwebhetri
Isixokelelwano esiqhagamshelwe kwigridi lufakelo olusisiseko olusebenzisa i-inverter eboshwe ngegridi. Ilungele abo banqwenela ukukhetha ukufakwa kwelanga ukuze kusetyenziswe indawo yokuhlala. Abathengi banokuzuza kwi-net metering. I-Net metering ivumela ukuba siqondise kwakhona nawaphi na amandla angaphezulu kwigridi. Ngale ndlela, abathengi kufuneka bahlawule kuphela umahluko kumandla abawusebenzisayo.Inkqubo edityanisiweyo yegridi ineepaneli zelanga ezifunxa imitha yelanga, eguqulwa ke ibe ngumbane othe ngqo (DC). I-DC ke isetyenziswa yi-inverter yesixokelelwano selanga esiguqula amandla e-DC ukuya kumbane otshintshanayo (AC). I-AC ingasetyenziswa ke zizixhobo zendlu ngendlela efanayo zixhomekeke kwisistim yegridi.
Inzuzo ephambili yokusebenzisa inkqubo edibeneyo yegridi kukuba ayibizi kakhulu kunezinye iintlobo zeenkqubo zePV zelanga. Ngaphaya koko, ibonelela ngokuguquguquka koyilo njengoko inkqubo ingafuneki ukuba inike amandla yonke imithwalo yekhaya. I-drawback ephambili yenkqubo edibeneyo yegridi kukuba ayinikezeli naluphi na ukhuseleko lokuphuma.
(B) IiNkqubo zePV eziQhagamshelwe ngeGridi ngebhetri
Ukubandakanya ibhetri kwi-PV system yegridi inika amandla angakumbi okuzimela ekhaya. Kukhokelela ekuncitshisweni kokuxhomekeka kumbane wegridi kunye nabathengisi bamandla kunye nesiqinisekiso sokuba umbane unokutsalwa kwigridi kwimeko apho inkqubo yelanga inganikeli amandla aneleyo.
2. IiNkqubo ezizimeleyo
Inkqubo ye-PV ezimeleyo (ekwabizwa ngokuba yi-off-grid system solar) ayiqhagamshelwanga kwigridi. Ngaloo ndlela, ifuna isisombululo sokugcina ibhetri. Iinkqubo ze-PV ezizimeleyo ziluncedo kwimimandla yasemaphandleni enobunzima bokudibanisa kwinkqubo yegridi. Ukusukela, ezi nkqubo azithembeli kugcino lwamandla ombane, zifanelekile kwizicelo zokunika amandla njengeempompo zamanzi, iifeni zokungenisa umoya, kunye neenkqubo zokufudumala kwelanga. Kubalulekile ukuqwalasela inkampani eyaziwayo ukuba uceba ukuya kwinkqubo ye-PV ezimeleyo. Oku kungenxa yokuba inkampani esekiweyo iya kuhlawula iiwaranti ixesha elide. Nangona kunjalo, ukuba iinkqubo ezizimeleyo zithathelwa ingqalelo ukuba zisetyenziswe ekhaya, kuya kufuneka ziyilwe ngendlela yokuba zikwazi ukuhlangabezana neemfuno zamandla zekhaya kunye neemfuno zokutshaja ibhetri. Ezinye iisistim ezizimeleyo zePV nazo zinejenereyitha ezigcinayo ezifakwe njengomaleko owongezelelweyo.
Nangona kunjalo, ilungiselelo elinjalo linokubiza ukuseta kunye nokunyamekela.
I-overhead ehambelana neenkqubo ezizimeleyo ze-PV zelanga kukuba zifuna ukukhangela rhoqo ngokuchasene ne-terminal corrosion kunye namanqanaba e-electrolyte yebhetri.
3. IiNkqubo zePV zeHybrid
Inkqubo yePV exutyiweyo yindibaniselwano yemithombo emininzi yamandla ukunyusa ukufumaneka kunye nokusetyenziswa kwamandla. Inkqubo enjalo inokunyusa amandla kwimithombo efana nomoya, ilanga, okanye iihydrocarbons. Ngaphaya koko, iinkqubo zePV ezixutyiweyo zihlala zixhaswa ngebhetri ukwandisa ukusebenza kakuhle kwenkqubo. Kukho iingenelo ezahlukeneyo zokusebenzisa inkqubo ye-hybrid. Imithombo emininzi yamandla ithetha ukuba inkqubo ayixhomekekanga kuwo nawuphi na umthombo wamandla. Umzekelo, ukuba imozulu ayihambisani nokuvelisa amandla aneleyo elanga, uluhlu lwePV lunokutshaja ibhetri. Ngokufanayo, ukuba kunomoya okanye kukho amafu, i-injini yomoya inokujongana neemfuno zokutshaja kwebhetri.Iinkqubo ze-Hybrid PV zifanelene kakhulu neendawo ezikwanti ezinoqhagamshelwano lwegridi olulinganiselweyo.
Ngaphandle kweenzuzo ezingentla, kukho imingeni embalwa ehambelana nenkqubo ye-hybrid. Ngokomzekelo, ibandakanya uyilo oluntsonkothileyo kunye nenkqubo yokufakela. Ngaphezu koko, imithombo emininzi yamandla inokunyusa iindleko zangaphambili.
Ukuqukumbela
Iinkqubo ezahlukeneyo zePV ezixoxwe ngasentla ziluncedo kwiindawo ezahlukeneyo zesicelo. Xa ukhetha ukufakela inkqubo enye, singathanda ukucebisa iiNkqubo ze-PV eziXhanyisiweyo zeGridi ngaphandle kweBhetri, emva kokulinganisa iindleko kunye nokusebenza kakuhle kwamandla.
