Joalo ka ha bohle re tseba, ha re khetha lebone la letsatsi la seterateng, re hloka ho etsa boitokisetso bo itseng.Ka mohlala, re lokela ho tseba hore na re ka kenya mabone hokae?Boemo ba tsela ke bofe, tsela e le 'ngoe, litsela tse peli?Ke matsatsi a makae a pula e sa khaotseng?Le moralo oa mabone bosiu ke ofe.
Ka mor'a ho tseba lintlha tsena kaofela, re ka tseba hore na re tla sebelisa matla a letsatsi le betri e kholo hakae, ebe re khona ho laola litšenyehelo.
Ha re nke mohlala, bakeng sa 12v, 60W streetlight, haeba e tla sebetsa lihora tse 7 bosiu bo bong le bo bong, 'me ho na le matsatsi a 3 a kamehla a lipula,' me karo-karolelano ea motšehare ke lihora tse 4.Palo e tjena.
1.Bokhoni ba Betri
a.Lebala la jwale
Hona joale =60W÷12V＝5A
b.Bala boholo ba betri
Betri=Nako ea hona joale* ea ho sebetsa letsatsi le letsatsi* matsatsi a pula e sa khaotseng=105AH.
Re hloka ho ela hloko, 105AH ha se matla a ho qetela, re ntse re hloka ho nahana ka taba ea ho tsoa le ho feta tefiso.Tšebelisong ea letsatsi le letsatsi, 140AH ke 70% feela ho 85% ha e bapisoa le maemo.
Betri e lokela ho ba 105÷0.85=123AH.
2.Matla a Solar Panel
Pele re bala matla a matla a letsatsi, re lokela ho tseba hore solar panel e entsoe ka silicon chips.Khafetsa phanele e le 'ngoe ea letsatsi e tla ba le 36pcs silicon chips ka ho bapa kapa ka letoto.Matla a silicon chip e 'ngoe le e' ngoe e ka ba 0.48 ho 0.5V, 'me motlakase oa karolo eohle ea letsatsi e ka ba 17.3-18V.Ntle ho moo, nakong ea ho bala, re hloka ho tlohela sebaka sa 20% bakeng sa karolo ea letsatsi.
Solar panel wattage ÷working voltage=(hona joale×ho sebetsa nako bosiu bo bong le bo bong×120%).
Solar panel Wattage Min=（5A×7h×120％）÷4h×17.3V＝182W
Solar panel Wattage Max=（5A×7h×120％）÷4h×18V＝189W
Leha ho le joalo, sena ha se matla a ho qetela a solar panel.Nakong ea ts'ebetso ea mabone a letsatsi, re boetse re hloka ho nahana ka tahlehelo ea mohala le tahlehelo ea molaoli.'Me karolo ea sebele ea letsatsi e lokela ho ba 5% ho feta ha e bapisoa le data ea lipalo 182W kapa 189W.
Solar panel Wattage Min＝182W×105％＝191W
Solar panel Wattage Max＝189W×125％＝236W
Ka kakaretso, molemong oa rona, betri e lokela ho ba ho feta 123AH, 'me karolo ea letsatsi e lokela ho ba pakeng tsa 191-236W.
Ha re khetha mabone a marang-rang a letsatsi, ho latela mokhoa ona oa ho bala, re ka khona ho tseba bokhoni ba motlakase oa letsatsi le libeteri ka borona, Sena se ka re thusa ho boloka litšenyehelo ho isa bohōleng bo itseng, e leng se tla boela se re tlisetse phihlelo e ntle ea mabone a ka ntle.
