Uyilo lwenkqubo yesikhululo soMbane weFotovlic, umyinge wokufakelwa kwemodyuli yeefotovoltaic kwimodyuli ye-inverter ye-Inverter ngu-DC /
I-parameter ebaluleke kakhulu yoyilo.Imilinganiselo yokusebenza ye-Photovoltaic yenkqubo ye- "Photovoltaic System, iqulathe le-1: 1, kodwa ngenxa yempembelelo yeemeko zokukhanya kunye neemodyuli zokukhanya, iimodyuli zefotovoltaic azinakufikelela kwi Amandla oLuxoki ixesha elininzi, kwaye i-inverter ngokusisiseko yonke isebenza engaphantsi kwesikhundla esipheleleyo, kwaye uninzi lwexesha likwinqanaba lokuchitha.
Kwinqanaba elikhutshwe ekupheleni kuka-Okthobha 2020, ububanzi bemifanekiso yezityalo zefotovoltaic bekukho ngokukhululekileyo, kwaye umlinganiselo ophezulu wamacandelo kunye ne-interster ufikelele kwi-1.8: 1. Umgangatho omtsha uya kwandisa kakhulu imfuno yamakhaya amacandelo kunye namantshontsho. Inokunciphisa iindleko zombane kwaye ikhawuleze ikukhawuleze ifike ixesha le-fotovoltaic party.
Eli phepha liza kuthatha inkqubo yokusasazwa kwefoto entsha eShandong njengomzekelo, kwaye ihlalutye kwimbono yamandla okukhutshelwa kweemodyuli zefotovoltaic, ilahleko yelahleko ebangelwe ngokubonelela, uqoqosho.
01
Imeko yokubonelela ngokubonelela ngeephaneli zelanga
-
Okwangoku, umndilili wokubonelela ngezityalo zamandla ePhotvoltaic emhlabeni uphakathi kwe-120% ne-140%. Esona sizathu siphambili sokubonelela ngokugqithisileyo kukuba iimodyuli ze-PV azikwazi ukufikelela kumandla encopho efanelekileyo ngexesha lokusebenza. Izinto zokuphembelela zibandakanya:
1). Ubungakanani be-radiation yemitha (ubusika)
2). Ubushushu obuqhelekileyo
3).
I-4) .Ukuziqhelanisa nemodyuli yemodyuli yemodyuli ayisiyo yonke imihla (umkhondo wokulandela umkhondo ungaphantsi kwento)
5).. Imodyuli yemodyuli yeSolotions:
I-6). Ukulahleka kwelahleko ngaphakathi nangaphakathi kwemitya yeemodyuli zelanga
I-curves yemihla ngemihla isizukulwana esinemilinganiselo eyahlukileyo yokwahlula-hlula
Kwiminyaka yakutshanje, ukubonelelwa ngokugqithisela kweefotovoltaic iinkqubo zefotovoltaic kubonakalise indlela eyandayo.
Ukongeza kwizizathu zokulahleka kwenkqubo, ukwehla kwamaxabiso amaxabiso ecandelo kwiminyaka yakutshanje kwaye ukuphuculwa kwetekhnoloji ye-inverter kukhokelele, ukwenza ukubonelela nge-upoastrical , ukubonelelwa ngokugqithisela kwamalungu kunokunciphisa iindleko zombane, ngokwenza oko kuphuculwe inqanaba langaphakathi lokubuya kweprojekthi, ke amandla okulwa abengozi yotyalo-mali lweprojekthi inyuswe.
Ukongeza, iimodyuli ezinamandla zefotovoltaic ziyeyona nto iphambili ekuphuhlisweni kwemveliso yefotovoltaic kweli nqanaba, ekwandisa ithuba lokunikezelwa kwamacandelo kunye nokunyuka komthamo ofakiweyo wefotovoltaic.
Ngokusekwe kwezi zinto zilapha ngasentla, ukubonelelwa ngokugqithisileyo kube yeyona nto uyilo lwePhotovoltaic.

Ukuthatha i-6kw yeSikhululo soMbane se-6kww se-Photoltaic etyalwe ngumnini njengomzekelo, iimodyuli ezingama-540w zeemodyuli, eziqhele ukusetyenziswa kwimakethi ezisasazwe, zikhethiwe. Kuqikelelwa ukuba umndilili we-20 kWh wombane unokuveliswa ngemini, kwaye umbane wonyaka wokuphalazwa malunga ne-7 300 kWh.
Ngokweeparamitha zombane zezinto, ezisebenzayo okwangoku zenqaku eliphezulu le-13a. Khetha i-Inverter ye-Inverter ye-GW6000-DNS-30 kwintengiso. Elona galelo liphezulu langoku kule ntsholongwane yi-16A, elinokuziqhelanisa nemarike yangoku. izinto eziphezulu zangoku. Ukuthatha ixabiso leminyaka engama-30 le-30 yemithombo yezixhobo zokukhanya kwi-Yataai City, kwiPhondo leShandong njengereferensi, iinkqubo ezahlukeneyo ezinemilinganiselo yokulwa eyahlukileyo yahlalutywa.
2.1 Ukusebenza kakuhle kwenkqubo
Kwelinye icala, ukubonelelwa ngokugqithisileyo kunyusa amandla ukuvelisa amandla, kodwa kwelinye icala, ngenxa yokwanda kwenani leemodyuli ze-SOR kwi-DC, ukulahleka kwemodyuli yelanga kumtya welanga kunye nelahleko ye Ukunyuka komgca we-DC, ke kukho umyinge wamanqanaba afanelekileyo, wandisa ukusebenza kwenkqubo. Emva kokulinganisa i-PVSYST, ukusebenza ngempumelelo phantsi kwenqanaba le-6KVA lenkqubo inokufumaneka. Njengoko kubonisiwe kwitheyibhile engezantsi, xa umyinge wamandla malunga no-1.1, inkqubo yokusebenza kakuhle kwenkqubo ifikelela kwinqanaba lokusetyenziswa kwecandelo lezinto zezona ziphezulu ngeli xesha.
Ukusebenza kwenkqubo kunye nemozulu yonyaka kunye nenqanaba elahlukileyo
2.2 Ukuvelisa amandla kunye nengeniso
Ngokwendlela yokusebenza kakuhle kwenkqubo phantsi kwenqanaba elihlukeneyo lokwahlula-hlula kunye nenqanaba lokuhlawulelwa kwethiyori kwiimodyuli kwiminyaka engama-20, inqanaba lonyaka, isigaba sonyaka esiphantsi konqobolo-mali onokufumaneka. Ngokwexabiso le-Grid ye-GRID le-0.395 yuan / kwh (i-BWH (i-Benchmark yoMbane woMbane ochithwayo eShandong), ingeniso yonyaka yoMbane woNyaka ibaliwe. Iziphumo zokubala zibonisiwe kwitafile engezantsi.
2.3 Uhlalutyo lweendleko
Indleko yile nto abasebenzisi beefoto zefoto yekhaya bakhathazekile kakhulu malunga. Ulwakhiwo Iakhawunti yexabiso eliphakathi lokugcina i-Akhawunti malunga ne-1% ukuya kwi-3% yeendleko zotyalo-mali. Kwindleko zizonke, i-akhawunti ye-photovoltaic modles malunga ne-50% ukuya kwi-60%. Ngokusekwe kwezi zinto zichithayo zenkcitho ezingasentla, i-Photovoltaic ye-Photovoltaic ye-Photovoltaic ye-Photovoltaic iphantse yaboniswa kule theyibhile ilandelayo:
Iindleko eziqikelelweyo zeenkqubo zokuhlala ze-PV
Ngenxa yemilinganiselo eyahlukileyo yokwahlula-hlula, iindleko zenkqubo ziya kwahluka, kubandakanya nezinto, iibrakethi, iintambo ze-DC, kunye nemirhumo yokufaka. Ngokwetheyibhile engentla, iindleko zemilinganiselo eyahlukileyo yokwahlula-hlula inokubalwa, njengoko kubonisiwe kumzobo ongezantsi.
Iindleko zenkqubo, izibonelelo kunye nokusebenza kakuhle phantsi kwenqanaba elahlukileyo

Ukuhlaziywa kwezibonelelo
-
Ingabonwa kolu hlalutyo lungentla onokuthi nangona umbane wonyaka kunye nengeniso iyakonyuka ngokunyuka komyinge wokubonelela ngokusebenza, indleko zotyalo mali iya kukhula. Ukongeza, le theyibhile ingentla ibonisa ukuba inkqubo yokusebenza kakuhle yi-1.1 amaxesha ngakumbi xa ihamba phambili.
Nangona kunjalo, ngokwembono yabatyali-mali, akwanelanga ukuqwalasela uyilo lweenkqubo zefotovoltaic kwinkqubo yobugcisa. Kuyimfuneko ukuhlalutya ifuthe lokwabiwa ngaphezulu kwengeniso yotyalo-mali evela kwimbono yoqoqosho.
Ngokweendleko zotyalo-mali kunye nengeniso yengeniso phantsi kwengeniso yexabiso elingaphezulu, indleko ze-KWH yeminyaka iminyaka engama-20 kunye nenqanaba lokuphuma kwirhafu lingabalwa.
I-LCOe kunye neRR phantsi kwenqanaba elahlukileyo
Njengoko kunokubonwa kulo mfanekiso ungentla, xa umyinge wolwabiwo mali luncinci, ukuvelisa amandla kunye nengeniso yenkqubo yokunyuka komgangatho wokwabiwa, kunye nengeniso eyandayo ngeli xesha kunokugubungela indleko ngaphezulu Ulwabiwo-mali. Xa i-1.5, inqanaba langaphakathi lokubuya i-IRR yoTyalo-mali lweNkqubo yeyona inkulu. Ke ngoko, ukusuka kwindawo yoqoqosho, i-1.5: 1 ngumyinge wamandla afanelekileyo kule nkqubo.
Ngendlela efanayo nakasentla, umyinge wamandla ofanelekileyo wenkqubo ophantsi kwamandla oqoqosho ubalwa ngokwembono yezoqoqosho, kwaye iziphumo zezi zilandelayo:

Ngokusebenzisa idatha yelanga yelanga yaseShandong, phantsi kwemiqathango yemilinganiselo eyahlukeneyo, amandla e-Photovoltaic yemveliso yokukhupha i-inverter efikelela kwi-inverter emva kokuba ilahlekile. Xa i-1.1, inkqubo yokulahleka kwenkqubo yeyona incinci yokusetyenziswa kwelona xesha liphezulu kakhulu. . Xa uyila inkqubo yefotovoltaic, hayi kuphela inqanaba lokusetyenziswa kwezinto phantsi kwezinto zobugcisa kufuneka kuthathelwe ingqalelo, kodwa noqoqosho yeyona nto iphambili kuyilo lweprojekthi.Ukubala kwezoqoqosho, inkqubo ye-8kw 1.3 yeyona nto ibalulekileyo, inkqubo ye-10 ye-10 ye-10 ye-1,2 yeyona nto iguqulelwa kakhulu, kwaye eyona nto ikhutshwayo .
Xa le ndlela inye isetyenziselwa ukubalwa koqoqosho lwemino-mveliso kunye noRhwebo, ngenxa yokuncitshiswa kweendleko kwi-Watt nganye yenkqubo, umlinganiselo ofanelekileyo wokuqoqosho uya kuba ngaphezulu. Ukongeza, ngenxa yezizathu zentengiso, iindleko zeefotovoltaic nazo ziya kwahluka kakhulu, eziya kuchaphazela kakhulu ukubalwa komyinge wokulinganisa ubungakanani. Esi sisizathu esisisiseko sokuba amazwe akhutshiweyo akhutshelwe izithintelo ekuyileni kwenkqubo yoyilo lweenkqubo zeefotovoltaic.
