Kaisy Hain Sab?

Main English Ki Bajaye Urdu mein Thread bana raha hun i dont know the rules!

Haan to dosto main ne yeh puchna tha ke Agr 2 Solar Panels (Shell Aman) 150watts Ko New Exide N135 Battery Ke Sath Lagaya Jae Baghair Charge Controller Ke To Battery Charge Hony mein Kitna Time Legi? Yaani Specific Gravity 1.250(+,-)0.02 aur Voltage 12.6 hasil karny k liye.

1 Solar Panel K Zariye Charging Ka Hisab Mainy Kuch Is Tarha Kiya Hai,

150(watt PV Panel) x 0.7(Assume PV Panel will give 70% Efficiency)=105watts

Agr PV Panel k terminals ky darmiyan Volt meter lagaun to 13.8volt ki reading deta hai,

So current ampere mein aisa hoga,

105(watts) /13.9=7.5A

Is Hisab se battery ko 7.5A charge rate mil raha hai to battery charge time will be,

135ah(assuming Exide N135 is 135ah) / 7.5A=18Hours(approx)

Kia mera hisab sahi hai? Agr nahi to please sahi kijiye..

Haan mujhe 2 PV Panels (1Mono,1Poly) k liye Charge Controller b suggest kijiye..

Umid hai tafsili jawab milega.
