Njengoko sonke sisazi, xa sikhetha isibane selanga, kufuneka senze amalungiselelo athile.Umzekelo, kufuneka sazi apho sizifakela khona izibane?Injani imeko yendlela, umgca omnye, iindlela ezimbini?Zingaphi iintsuku ezinetha rhoqo?Kwaye yintoni isicwangciso sokukhanyisa ebusuku.
Emva kokwazi zonke ezi datha, sinokwazi ukuba ingakanani ipaneli yelanga kunye nebhetri esiza kuyisebenzisa, kwaye ke sinokulawula iindleko.
Makhe sithathe umzekelo, kwi-12v, i-60W yesitrato, ukuba iya kusebenza iiyure ezi-7 ubusuku bonke, kwaye kukho iintsuku ezi-3 zemvula eziqhubekayo, kunye nomlinganiselo wemini yieyure ezi-4.Ubalo luhamba ngolu hlobo lulandelayo.
1.Umthamo webhetri
a.Bala umsinga
Okwangoku =60W÷12V＝5A
b.Bala umthamo webhetri
Ibhetri=Ixesha langoku* lokusebenza yonke imihla* iintsuku ezinetha rhoqo=105AH.
Kufuneka sinikele ingqalelo, i-105AH ayilona umthamo wokugqibela, sisadinga ukuqwalasela ukukhutshwa ngokugqithisileyo kunye nomcimbi ogqithisiweyo.Ekusetyenzisweni kwansuku zonke, i-140AH kuphela i-70% ukuya kwi-85% xa kuthelekiswa nomgangatho.
Ibhetri kufuneka ibe yi-105÷0.85=123AH.
2.Ipaneli yeSolar Wattage
Ngaphambi kokubala umbane wepaneli yelanga, kufuneka sazi ukuba iphaneli yelanga yenziwe ngeetshiphusi zesilicon.Rhoqo iphaneli enye yelanga iya kuba ne-36pcs ye-silicon chips ngokuhambelanayo okanye kuthotho.I-voltage ye-silicon chip nganye i malunga ne-0.48 ukuya kwi-0.5V, kwaye i-voltage ye-solar panel yonke i malunga ne-17.3-18V.Ngaphandle koko, ngexesha lokubala, kufuneka sishiye indawo ye-20% yepaneli yelanga.
Amandla ombane wephaneli yelanga ÷ amandla ombane osebenzayo=(yangoku×ixesha lokusebenza rhoqo ebusuku×120%).
Iphaneli yeSolar Wattage Min=(5A×7h×120％）÷4h×17.3V＝182W
Iphaneli yeSola yoWatha Ubukhulu obuninzi=(5A×7h×120％）÷4h×18V＝189W
Nangona kunjalo, oku akukona ukutshatyalaliswa kokugqibela kwepaneli yelanga.Ngexesha lokusebenza kwezibane zelanga, kufuneka kwakhona siqwalasele ukulahleka kwentambo kunye nokulahleka komlawuli.Kwaye iphaneli yangempela yelanga kufuneka ibe yi-5% ngaphezulu xa kuthelekiswa nedatha yokubala i-182W okanye i-189W.
Iphaneli yelanga iWattage Min＝182W×105％＝191W
Iphaneli yeSolar Wattage Max＝189W×125％＝236W
Konke kuzo zonke, kwimeko yethu, ibhetri kufuneka ibe ngaphezu kwe-123AH, kwaye iphaneli yelanga kufuneka ibe phakathi kwe-191-236W.
Xa sikhetha izitrato zelanga, ngokusekelwe kule fomyula yokubala, sinokubala umthamo wepaneli yelanga kunye neebhetri ngokwethu, Oku kunokusinceda ukuba sigcine iindleko ukuya kwinqanaba elithile, eliya kuthi lisiphathele amava okukhanya angaphandle.
