Namuhla, abantu abaningi bafuna ukuhlanganisa iphampu yokushisa yomthombo womoya nesistimu yeSolar PV ukuze bonge amandla engeziwe. Ngaphambi kwalokho, ake sifunde ulwazi oluthile mayelana nomehluko phakathi kwezinhlobo zamasistimu elanga le-PV.
Kunezinhlobo Ezintathu Ezivelele zeSolar PV Systems:
Igridi Exhunyiwe noma I-Utility-Interactive Systems
Ama-Stand-alone Systems
Ama-Hybrid Systems
Ake Sihlole Izinhlobo Ezintathu Zezinhlelo Ze-PV Ngemininingwane:
1. Uhlelo Oluxhumeke Igridi
Amasistimu e-PV axhumeke kugridi awadingi ukugcinwa kwebhethri. Nokho, kuhlale kukwazi ukwengeza ibhethri kusistimu yelanga exhunywe kugridi.
(A) Amasistimu e-PV Axhumeke kwigridi ngaphandle kwebhethri
Isistimu exhunywe kugridi wukufakwa okuyisisekelo okusebenzisa i-inverter eboshwe ngegridi. Ilungele labo abafisa ukukhetha ukufaka i-solar ukuze bayisebenzisele ukuhlala. Abathengi bangazuza ku-net metering. I-Net metering isivumela ukuthi siqondise kabusha noma imaphi amandla ayinsalela kugridi. Ngale ndlela, amakhasimende kufanele akhokhe kuphela umehluko wamandla awasebenzisayo.Isistimu exhunywe kugridi inamaphaneli elanga athatha imisebe yelanga, eguqulwa ibe yi-direct current (DC). I-DC ibe isisetshenziswa i-inverter yesistimu sonozungezilanga eguqulela amandla e-DC abe i-alternating current (AC). I-AC ingase isetshenziswe amadivayisi asendlini ngendlela efanayo athembele ohlelweni lwegridi.
Inzuzo enkulu yokusebenzisa uhlelo oluxhunywe kugridi ukuthi lubiza kancane kunezinye izinhlobo zezinhlelo ze-solar PV. Ngaphezu kwalokho, inikeza ukuguquguquka komklamo njengoba isistimu ingadingi amandla kuyo yonke imithwalo yasendlini. I-drawback eyinhloko yesistimu exhunywe kwigridi ukuthi ayinikezi noma yikuphi ukuvikeleka kokuphuma.
(B) Amasistimu e-PV Axhumeke kwigridi anebhethri
Ukufaka ibhethri ohlelweni lwe-PV yegridi kunikeza amandla amaningi okuzimela ekhaya. Kuholela ekuncipheni kokuthembela kugesi wegridi kanye nezitolo zamandla kanye nesiqiniseko sokuthi ugesi ungadonsa kugridi uma kwenzeka isistimu yelanga ingawakhiqizi amandla anele.
2. Amasistimu Azimele
Isistimu ye-PV ezimele (ebuye ibizwe ngokuthi i-off-grid solar system) ayixhunyiwe kugridi. Ngakho, kudinga isixazululo sebhethri. Amasistimu e-PV azimele awusizo ezifundeni zasemakhaya ezinobunzima bokuxhuma ohlelweni lwegridi. Njengoba, lawa masistimu awancikile ekugcinweni kwamandla kagesi, alungele izinhlelo zokusebenza zokunika amandla njengamaphampu amanzi, izifeni zokungenisa umoya, namasistimu okushisa asebenzisa ilanga. Kubalulekile ukucabangela inkampani ehlonishwayo uma uhlela ukuthola uhlelo oluzimele lwe-PV. Lokhu kungenxa yokuthi inkampani esunguliwe izofaka amawaranti isikhathi eside. Kodwa-ke, uma amasistimu azimele ecatshangelwa ukuthi asetshenziswe ekhaya, kuzodingeka aklanywe ngendlela yokuthi akwazi ukubhekana nezidingo zamandla omndeni kanye nezidingo zokushajwa kwebhethri. Amanye amasistimu e-PV azimele nawo anamajeneretha ayisipele afakwe njengesendlalelo esengeziwe.
Nokho, ilungiselelo elinjalo lingabiza ukulimisa nokulinakekela.
I-overhead ehlotshaniswa nezinhlelo ze-PV ezizimele zelanga ukuthi zidinga ukuhlolwa njalo ngokumelene nokugqwala kwetheminali kanye namazinga e-electrolyte yebhethri.
3. IHybrid PV Systems
I-hybrid PV system iyinhlanganisela yemithombo eminingi yamandla ukuze kuthuthukiswe ukutholakala nokusetshenziswa kwamandla. Isistimu enjalo ingasebenzisa amandla emithonjeni efana nomoya, ilanga, noma ama-hydrocarbon. Ngaphezu kwalokho, amasistimu e-hybrid PV avame ukusekelwa ngebhethri ukuze kukhuliswe ukusebenza kahle kwesistimu. Kunezinzuzo ezihlukahlukene zokusebenzisa uhlelo lwe-hybrid. Imithombo eminingi yamandla isho ukuthi uhlelo aluncikile kunoma yimuphi umthombo othile wamandla. Isibonelo, uma isimo sezulu singavumi ukukhiqiza amandla elanga anele, uhlelo lwe-PV lungashaja ibhethri. Ngokufanayo, uma kunomoya noma kuguqubele, i-wind turbine ingabhekana nezidingo zokushaja zebhethri.Amasistimu e-Hybrid PV afaneleka kakhulu ezindaweni ezingazodwa ezinokuxhumeka kwegridi okulinganiselwe.
Naphezu kwezinzuzo ezingenhla, kunezinselelo ezimbalwa ezihlobene nesistimu ye-hybrid. Ngokwesibonelo, kuhilela umklamo oyinkimbinkimbi kanye nenqubo yokufaka. Ngaphezu kwalokho, imithombo eminingi yamandla ingakhuphula izindleko ezingaphambili.
Isiphetho
Amasistimu e-PV ahlukahlukene okukhulunywe ngawo ngenhla awusizo ezindaweni ezahlukene zokusetshenziswa. Uma sikhetha ukufaka isistimu eyodwa, singathanda ukuncoma I-Grid-Connected PV Systems ngaphandle kwebhethri, ngemva kokulinganisa izindleko nokusebenza kahle kwamandla.
