Xa sithetha ngesixeko ebusuku, izibane zesitalato endleleni ziyinxalenye ebalulekileyo. Kwiminyaka yakutshanje, ingcamango yokukhusela indalo esingqongileyo iye yanda kakhulu phakathi koluntu, kwaye izibane zasezitalatweni ezisebenza ngelanga ziye zatsala ingqalelo enkulu. Ukuze kuqinisekiswe ukuba ezi zibane zesitalato zinokukhanyisa ngokuthembekileyo indlela ebusuku, kufuneka siqwalasele iiparitha ezininzi ezibalulekileyo ezibandakanya umbane wezibane zesitrato, amandla ephaneli ye-photovoltaic, amandla ebhetri kunye nokuzinza komlawuli. Uyilo kunye nokucwangciswa kwenkqubo yokukhanya ezitalatweni zelanga zizinto eziphambili. Inxulumene nokuba indlela inokukhanya ngokufanelekileyo kwaye ngokusisigxina
Kutheni sifanele sinikele ingqalelo kwiiparameters zokukhanya kwesitalato selanga
Iipaneli zelanga zihambelana nomthamo wokuqokelela amandla, oko kukuthi, kuthatha ixesha elingakanani ukuhlawula ngokupheleleyo ibhetri ngokukhanya kwelanga okusebenzayo. Umthamo webhetri yeLiFePO4 kufuneka inxulunyaniswe nokuba isibane sesitrato sinokuqhutywa ngokuqhubekayo ngexesha lokukhanyisa ebusuku. Ezi parameters kunye namacandelo eenkqubo zokukhanyisa ezitalatweni zelanga, ukuba zilungiswe ngokungekho ngqiqweni, ziya kuchaphazela ukusebenza okuqhelekileyo kweenkqubo zokukhanyisa ezitalatweni zelanga. Umzekelo, ukuba ipaneli yelanga kunye nomthamo webhetri uncinci kakhulu, izibane zesitrato zisenokungakwazi ukuhlangabezana neemfuno zamandla ebusuku, njl. Ngokuchasene noko, ukuqonda okunzulu kwezi parameters kunokunceda ukudala isitalato selanga esisebenzayo, esinengqiqo kunye nesizinzileyo. iinkqubo zokukhanya ezibonelela ngokukhanya okuthembekileyo edolophini
Bala iiyure ze-watt zizonke ngosuku kwi-street lig
Iiyure ezipheleleyo ze-watt-umbane amandla ombane asetyenziswa yinkqubo yokukhanyisa izitalato zelanga imihla ngemihla, echaphazela ngokuthe ngqo umthamo webhetri kunye nokukhethwa kwamandla kwepaneli yelanga. Ukubala ukusetyenziswa kwamandla kwansuku zonke (iiyure ezipheleleyo ze-watt-iiyure) zokukhanya kwesitrato, kufuneka ukwazi izinto ezimbini eziphambili: ukuchithwa kwesigxina ngexesha lexesha elihlukeneyo kunye nenani leeyure zokusebenza ngexesha ngalinye. Ifomula yokubala ii-watt-yure zizonke ngosuku imi ngolu hlobo lulandelayo: Iiyure ze-watt zizonke ngosuku = Ukusetyenziswa kombane 1 (W) × Inani leeyure zokusebenza kwixesha elahlukileyo. Ngokomzekelo, ukucinga ukukhanya kwesitrato kunye nombane we-100W ukukhanya kwesitalato kusebenza iiyure ze-12 ngosuku, kunye neeyure zokuqala ze-5 zisebenza kwi-100% yamandla kunye neeyure ze-7 zokugqibela zisebenza kumandla angama-50%, ngoko i-watt-yure yemihla ngemihla ibalwa. ngolu hlobo lulandelayo: Iiyure ze-watt zemihla ngemihla = 100W × iiyure ze-5 + 50W × iiyure ze-7 = iiyure ze-850 watt (Wh). Iziphumo zokubala zingasetyenziswa kula macandelo alandelayo ukufumanisa umthamo webhetri kunye nombane wepaneli yelanga efunekayo kwisibane sesitrato selanga.
Ibhetri yeenkqubo zokukhanyisa ezitalatweni zelanga - umthamo
Uhlobo lwebhetri olucetyiswayo lokusetyenziswa kwiinkqubo ze-solar photovoltaic ziibhetri zomjikelezo onzulu. Iibhetri ze-deep cycle zenzelwe ukutshaja ngokukhawuleza emva kokukhutshwa kumanqanaba aphantsi kwamandla okanye ukutshaja ngokuqhubekayo kunye nokukhupha iminyaka emininzi. Ibhetri kufuneka ibenkulu ngokwaneleyo ukugcina amandla awoneleyo okuqhuba ukukhanya kwesitrato se-LED ebusuku nangeentsuku ezinamafu. Iinkqubo zokukhanyisa ezitalatweni zelanga zihlala zisebenzisa iibhetri ze-lithium (LiFePO4). Inobomi obude, ikhuselekile kwaye iphakamileyo
Bala iiwatts zizonke ezisetyenziswa sisibane sokukhanya ngosuku. Bala uguqulo lwenkqubo esebenzayo njenge-95% Bala ubunzulu bokukhutshwa kwebhetri. iibhetri ze-lithium zibalwa njenge-95% Bala inani leentsuku zokusebenza ezizimeleyo (oko kukuthi, inani leentsuku inkqubo kufuneka isebenze ngaphandle kweepaneli ze-photovoltaic ukuvelisa umbane) Umthamo webhetri ofunekayo (Wh) = Iiyure zeWatt zizonke (ngosuku) x Iintsuku zokuzimela / 0.95 / Ubunzulu bokukhutshwa kwebhetri yomjikelezo onzulu
Uphononongo lwe-E-LITE lweenkqubo zokukhanyisa ezitalatweni zelanga
Okwangoku, umthengi wethu usebenza kwiprojekthi yokukhanya ezitalatweni zelanga. Umthengi ufuna ukusebenzisa izibane zesitalato ze-115W zelanga, ezingadingi abenzi boluvo kunye nokusebenzisa i-PWM dimming, kodwa kufuneka ukuseta ixesha lobumnyama. Umsebenzi othile osekelwe kwixesha elithile ngolu hlobo lulandelayo: ixesha lokuqala li-100% kwaye liyaqhubeka lisebenza iiyure ze-5; ixesha lesibini li-50% kwaye liyaqhubeka nokusebenza iiyure ze-7; apho kufuneka kuphela ukukhanya kobusuku obunye. Ixesha lokukhanya kwelanga(Ukutshaja.
Ubume bendlela buziimitha ezi-8 ububanzi, kunye neendlela zokuhamba ngeemitha ezi-1.5 kumacala omabini. Ukuphakama kwesibonda sokukhanya siimitha ezili-10, ubude be-cantilever bu-1 mitha, kwaye umgama phakathi kwepali yokukhanya kunye ne-curb yi-36 yeemitha, ehlangabezana neemfuno zokukhanya kwe-M2. Ngokweziphumo zokulinganisa ukukhanyisa kwe-E-LITE, kuboniswa ukuba uchungechunge lwe-115W Omni lufanelekile kakhulu.
Watt-iiyure ze
Ngokusekelwe kwiimeko zeprojekthi, sibale owona setyenziso lwamandla ngolu hlobo lulandelayo:
Ukusetyenziswa kokukhanya kwesitrato kukonke = (115W x 5 iiyure) + (57.5W x 7 iiyure) = 977.5Wh/ngosuku
Umthamo we
Ngokuxhomekeke kwimeko yeprojekthi, ekubeni inani lexesha lokusebenza libusuku obunye kuphela. Emva koko siguqulela le mfuneko yamandla
umthamo webhetri, kuthathelwa ingqalelo amandla ombane wenkqubo yethu yebhetri yi-25.6V
Umthamo webhetri = Ukusetyenziswa kokukhanya kwesitrato kukonke 977.5WH×(0+1)/25.6V/95%/95%=42.3AH
Isiphelo: Umthamo webhetri: 25.6V/42A
(umthamo webhetri enye yi-6AH, ngoko ke i-42.3AH isondezwe kwi-42AH
Amanzi e
I-1, Ubuncinci bomthamo wokuvelisa amandla wepaneli yebhetri ngosuku (ibhetri iya kuhlawuliswa ngokupheleleyo ngosuku olunye-6hrs)
25.6x42AH=1075.2WH
2, Ubuncinci bokuvelisa amandla ngoku kwipaneli yebhetri
1075.6WH/6H=179.2W 3、Ubuchule bokuguqula inkqubo 95%
179.2W/95%=188.63
Ngokusekelwe kwiziphumo, sinokukhetha ukufaka i-1pc 36V / 190W (i-99% yokhuseleko lokutshaja into egciniweyo) imodyuli yephaneli yelanga ukuhlangabezana neemfuno zamandla zeprojekthi.
