Kamar yadda muka sani, lokacin da muka zaɓi hasken titi na rana, muna buƙatar yin wasu shirye-shirye.Misali, muna bukatar mu san inda za mu saka fitulun?Menene yanayin hanya, layi daya, hanyoyi biyu?Kwanaki nawa akai akai?Kuma menene shirin hasken dare.
Bayan sanin duk waɗannan bayanan, za mu iya sanin girman hasken rana da baturi da za mu yi amfani da su, sannan za mu iya sarrafa farashin.
Bari mu dauki misali, don 12v, 60W fitilar titi, idan zai yi aiki na tsawon sa'o'i 7 kowane dare, kuma akwai kwanaki 3 akai-akai, kuma rabon hasken rana shine awa 4.Lissafin shine kamar haka.
1.Ƙarfin Baturi
a. Yi lissafin halin yanzu
Yanzu = 60W÷12V：5A
b.Yi lissafin ƙarfin baturi
Baturi=Yanzu*lokacin aiki yau da kullum* ruwan sama akai-akai=105AH.
Muna buƙatar kula da hankali, 105AH ba shine ƙarfin ƙarshe ba, har yanzu muna buƙatar la'akari da batun zubar da kaya da yawa.A cikin amfanin yau da kullun, 140AH shine kawai 70% zuwa 85% idan aka kwatanta da ma'auni.
Batirin ya zama 105÷0.85=123AH.
2.Solar Panel Wattage
Kafin kididdige wattage na hasken rana, ya kamata mu sani cewa hasken rana an yi shi da kwakwalwan kwamfuta na silicon.A kai a kai daya hasken rana panel zai sami 36pcs silicon kwakwalwan kwamfuta a layi daya ko a cikin jerin.Wutar lantarki na kowane guntu na silicon yana kusan 0.48 zuwa 0.5V, kuma ƙarfin wutar lantarki gabaɗaya na hasken rana yana kusan 17.3-18V.Bayan haka, yayin lissafin, muna buƙatar barin 20% sarari don panel na hasken rana.
Solar panel wattage ÷ aiki ƙarfin lantarki = (lokacin aiki × yanzu kowane dare × 120%).
Solar panel Wattage Min=(5A×7h×120（））÷4h×17.3V：182W
Solar panel Wattage Max=(5A×7h×120（））÷4h×18V：189W
Duk da haka, wannan ba shine ƙarshen wutar lantarki na hasken rana ba.Yayin aikin hasken rana, muna kuma buƙatar la'akari da asarar waya da asarar mai sarrafawa.Kuma ainihin hasken rana ya kamata ya zama fiye da 5% idan aka kwatanta da bayanan lissafin 182W ko 189W.
Solar panel Wattage Min：182W×105＄？191W
Solar panel Wattage Max：189W×125＄？236W
Gabaɗaya, a cikin yanayinmu, baturi ya kamata ya zama fiye da 123AH, kuma hasken rana ya kamata ya kasance tsakanin 191-236W.
Lokacin da muka zaɓi fitilun hasken rana, bisa ga wannan ƙididdiga na ƙididdiga, za mu iya gano ƙarfin hasken rana da batura da kanmu, Wannan zai iya taimaka mana mu ajiye farashin har zuwa wani lokaci, wanda kuma zai kawo mana kyakkyawan haske na waje.
