Yintoni inkqubo yokugcina amandla e-photovoltaic?
Inkqubo yokugcina amandla e-photovoltaic yindibaniselwano yezixhobo kunye netekhnoloji eguqula amandla elanga abe ngamandla ombane ukuze anike izixhobo zasekhaya ngelixa egcina angaphezulu ukuze asetyenziswe ebusuku okanye xa kungekho mandla ombane.
Yintoni na kwaye zeziphi izinto eziphambili?
1. Imodyuli ye-Photovoltaic: ineemodyuli ezininzi ze-photovoltaic (ezaziwa ngokuba ziiphaneli zelanga) ezinoxanduva lokubamba ukukhanya kwelanga nokuliguqula libe ngumbane othe ngqo.
2. Iiraki, izixhobo kunye neentambo: zisetyenziselwa ukulungisa iiphaneli zelanga kunye nokuthutha amandla e-DC avelisiweyo ukuya kwi-inverter.
3. Ii-Inverters (ii-inverters eziqhagamshelwe kwigridi kunye nee-inverters ezingaphandle kwegridi): Amandla atshintshanayo (AC) enziwa ngokuguqula amandla angqalileyo (DC) aveliswa ziiphaneli zelanga, kwaye agcine amandla agqithisileyo kwinkqubo yokugcina amandla, enokuqhagamshelwa kwigridi yesixeko.
4. Izixhobo zokugcina amandla: Ngokwesiqhelo zibhekisa kwiibhetri, ezifana neebhetri ze-lithium kunye nezinye iintlobo zeebhetri, ezigcina umbane oveliswa ngamandla elanga ongasetyenziswa ngoko nangoko nge-inverter ukuze usetyenziswe kamva.
5. I-EMS kunye ne-BMS: I-EMS yinkqubo ejonga kwaye ilawula ukusebenza kwenkqubo yonke ukuqinisekisa ukuba zonke iindawo zisebenza ngokufanelekileyo nangokukhuselekileyo. I-BMS yinkqubo yolawulo lwebhetri yokugcina, ephucula kwaye ilawula ukutshaja nokukhupha ibhetri.
6. Ibhokisi yokudibanisa: ibandakanya zonke iintlobo zezixhobo zokukhusela kunye neeswitshi, ezinje ngokukhusela ukuvuza (ukukhusela umbane) phakathi kwe-solar access inverter, ii-fuses, ii-DC circuit breakers, ii-utility input circuit breakers, ii-uninterruptible power supply output circuit breakers, njl.njl.
Isiphumo se-Photovoltaic, indlela yokufumana umbane kumandla elanga
1. Ukufunxwa kwee-photon: Xa ukukhanya kwelanga (kuquka neminye imithombo yokukhanya) kubetha izinto (i-silicon) zephaneli yelanga, amandla ee-photon afunxwa zizinto ze-semiconductor.
2. Ukukhuthazwa kwee-elektroni: Amandla e-photon afunxiweyo abangela ukuba ii-elektroni ezikwi-semiconductor zitsibe ukusuka kwi-valence band ziye kwi-conduction band, zitshintshe ukusuka kwi-bound state ukuya kwi-free state.
3. Ukuveliswa kwee-electron-hole pairs: Xa i-electron ivuselelwe kwi-conduction band, ishiya umngxuma kwi-valence band. Le electron kunye nomngxuma zenza i-electron-hole pairs.
4. Ukuseka intsimi yombane: Iindawo zohlobo lwe-P kunye nohlobo lwe-N zihlala zikhona kwizinto ze-photovoltaic, kwaye ekudibaneni kwezi ndawo zimbini (oko kukuthi, indibano ye-PN), kwakheka intsimi yombane yangaphakathi.
5. Ukuqhuba ukuhamba kwee-elektroni: Le ntsimi yombane yangaphakathi iqhuba ii-elektroni ezikhululekileyo ukuba zihambe ziye kummandla wohlobo lwe-N kunye nemingxunya ukuba ziye kummandla wohlobo lwe-P, kwaye le ntshukumo idala umsinga.
6. Ukuqokelela umbane: Nge-inverter, lo mbane uguqulwa ube ngumbane we-AC okanye we-DC uze ugcinwe kwinkqubo yokugcina umbane ukuze usetyenziswe kamva.
Indlela ii-inverters eziqhagamshelwe kwigridi kunye nezingasebenzi kwigridi ezisebenza ngayo kunye nendlela yazo yokusebenza
1. I-inverter eqhagamshelwe kwigridi iguqula amandla e-DC aveliswa ziiphaneli zelanga abe yi-voltage efanelekileyo yebhasi ye-inverter nge-MPPT module, ize emva koko iyiguqule ibe ngamandla e-AC ngokusebenzisa izixhobo ze-elektroniki ukuze ibonelele ngezixhobo zasekhaya, kwaye ukuba kukho amandla agqithisileyo, iya kuguqulwa ibe yi-voltage efanayo naleyo yenkqubo yokugcina kwaye itshajwe kwinkqubo yokugcina ukuze igcinwe, kwaye ukuba kukho amandla agqithisileyo, iya kuguqulwa kwaye ifakwe kwigridi yamandla.
2. Iinkqubo zokugcina amandla ze-PV zineendlela zokuzivelisela ngokwazo kunye nezokuzisebenzisa ngokwazo, iindlela zokucheba i-peak kunye neendlela zokuzalisa intlambo, kunye neendlela zokubeka phambili ibhetri.
Indlela yokuzivelisela nokuzisebenzisela: umbane oveliswa ziiphaneli zelanga uguqulwa ube yi-alternating current (AC) kwaye unikwe ngqo kwizixhobo zasekhaya, ngelixa umbane ongaphezulu utshajwa kwinkqubo yokugcina; ukuba umbane oveliswa ziiphaneli zelanga awanelanga ukusetyenziswa zizixhobo zasekhaya, uzaliswa kwakhona kusetyenziswa igridi yamandla yesixeko.
Indlela yokuTshava eNcinci kunye neNdlela yokuZalisa iNtlambo: Ngexesha elimiselweyo, amandla e-AC avela kwigridi yesixeko aya kuguqulwa abe ngamandla e-DC aze atshajwe kwinkqubo yokugcina amandla; ngexesha elimiselweyo, amandla e-DC kwinkqubo yokugcina amandla aya kuguqulwa abe ngamandla e-AC ukuze anikezelwe kwizixhobo zasekhaya; ukuba amandla ebhetri awanelanga, aya kongezelelwa yigridi yesixeko.
Imo Yokubaluleka Kwebhetri: Nokuba imeko injani na, qala uqinisekise ukuba amandla enkqubo yokugcina amandla agcwele, xa amandla elanga evelisa amandla angakumbi, aya kuguqulwa ngokuthe ngqo abe ngamandla e-AC ukuze asetyenziswe yibhetri yasekhaya, kwaye xa umsebenzi woqhagamshelo lwegridi uvuliwe, okungaphezulu kuya kongezwa kwigridi yesixeko.
Indlela yokuyila nokubala ukuba zingaphi iiphaneli zelanga ze-W ekufuneka zifakwe
Iphaneli yelanga: LESSO 550W
Ubungakanani: L 2278 x 1134mm malunga ne-2.6 sq. ft.
Ubunzima: 28kg
Amandla: 550W
Ifomula yokubala indawo:
Qaphela: Xhasa iiphaneli zelanga ezingaphantsi kwe-7KW
Amandla apheleleyo ephaneli yelanga: 550W*12=6.6KW
Indawo yophahla efunekayo: 12 x 2.6 sq. ft. = 31.2 sq. ft.
Ubalo lokuveliswa kwamandla emihla ngemihla:
Umzekelo, thabatha iWenzhou, eTshayina, ilanga liphezulu liziiyure eziyi-3.77, ngewati nganye ngonyaka umbane uvelisa i-1.088KWH, ukusetyenziswa kweeyure ngonyaka kusetyenziswa iiyure eziyi-1087.08. I-engile yokufakelwa: iidigri ezili-18
Ukuveliswa kwamandla ombane okukhawulezayo imihla ngemihla = 6.6KW x 3.77H = 24.88KWH
Ukuveliswa kwamandla ngonyaka = 6.6KW x 1087.08H = 7174.728KWH
