E like me kā mākou e ʻike ai, ke koho mākou i ke kukui alanui o ka lā, pono mākou e hoʻomākaukau.No ka laʻana, pono mākou e ʻike i kahi e hoʻokomo ai i nā kukui?He aha ke kūlana alanui, hoʻokahi ala, ʻelua ala?Ehia la ua mau?A he aha ka hoʻolālā kukui i nā pō.
Ma hope o ka ʻike ʻana i kēia mau ʻikepili āpau, hiki iā mākou ke ʻike i ka nui o ka panel solar a me ka pākaukau a mākou e hoʻohana ai, a laila hiki iā mākou ke hoʻomalu i ke kumukūʻai.
E lawe kakou i kumu hoohalike, no ke kukui alanui 12v, 60W, ina e hana ia no 7 hora i kela po keia po, a he 3 mau la ua mau, a o ka ratio o ke ao he 4 hora.Penei ka helu ana.
1.Ka nui o ka Battery
a.E helu i ke au
ʻO kēia manawa =60W÷12V＝5A
b.E helu i ka mana o ka pila
Batri=I kēia manawa* manawa hana i kēlā me kēia lā* mau lā ua mau=105AH.
Pono mākou e hoʻolohe, ʻaʻole ʻo 105AH ka mana hope loa, pono mākou e noʻonoʻo i ka pilikia o ka hoʻokuʻu ʻana a me ka uku.I ka hoʻohana ʻana i kēlā me kēia lā, ʻo 140AH wale nō 70% a 85% i hoʻohālikelike ʻia i ka maʻamau.
He 105 ÷ 0.85=123AH ka Battery.
2.ʻO ka Watta Panel Solar
Ma mua o ka helu ʻana i ka wattage panel solar, pono mākou e ʻike ua hana ʻia ka panel solar me nā ʻāpana silika.Loaʻa i hoʻokahi panela solar he 36pcs mau ʻāpana silika ma ke ʻano like a i ʻole ka pūʻulu.ʻO ka volta o kēlā me kēia pahu silika ma kahi o 0.48 a 0.5V, a ʻo ka volta o ka panel solar holoʻokoʻa ma kahi o 17.3-18V.Ma waho aʻe, i ka wā o ka helu ʻana, pono mākou e waiho i 20% wahi no ka panel solar.
ʻO ka wattage o ka panela solar ÷ka uila hana=(i kēia manawa×ka manawa hana i kēlā me kēia pō×120%).
Pākuʻi lā Wattage Min=（5A×7h×120％）÷4h×17.3V＝182W
Pākuʻi lā Wattage Max=（5A×7h×120％）÷4h×18V＝189W
Akā naʻe, ʻaʻole kēia ka wattage hope loa o ka panel solar.I ka wā o ka hana ʻana o nā kukui lā, pono mākou e noʻonoʻo i ka nalo uea a me ka nalowale o ka mea hoʻokele.A he 5% ka nui o ka panela solar maoli i ka helu helu 182W a i ʻole 189W.
Pākuʻi lā Wattage Min＝182W×105％＝191W
Pane lā Wattage Max＝189W×125％＝236W
ʻO nā mea āpau, i kā mākou hihia, ʻoi aku ka nui o ka pākaukau ma mua o 123AH, a ʻo ka panel solar ma waena o 191-236W.
Ke koho mākou i nā kukui alanui o ka lā, e pili ana i kēia helu helu, hiki iā mākou ke noʻonoʻo i ka hiki o ka panel solar a me nā pihi iā mākou iho.
