hi

I have a 105aH 12Volt lead acid battery, that i would like to charge in one day.

The solar vendors in my region says we have 6 hours effective sun light.

I also understand that it is best not to discharge the battery below 50% DOD.

So is it correct if i say the following.

50% DOD is 105/2=52.5ah i need from the panels in 6 hours. So i look at 52.5/6=8.75 amps an hour from the panels.

So if a look at 12V PV panels, i would need 8.75*12=105 watt panels. Is this correct?

If i get 2x50Watt 12V PV panels and hook them up in serie, do i have then 100Watt 24V input to the batteries?

This will give then 100/24=4.17 amps an hour, is this correct?

Why is it less than 1x105watt 12Volt PV panel, which gives 8.75amps an hour?

I am new to the world of solar, so please forgive me if the maths is wrong.

Any answer would be appreciated, thank you.
