Technically, all you need to charge a 12v battery is a solar panel with a 12v rating. This can be any solar panel, although the bigger it’s, the quicker your battery will charge. Anything under 5–10 watts is not enough, as these will only “trickle charge” your battery very slowly.
A 10-watt solar panel produces roughly 0.83ah of current under ideal conditions, and so it would take around 120 hours to fully charge a 100ah battery or 60 hours for a 50ah battery. Again, this is best for trickle charging only. How Long Does It Take A 25w Solar Panel To Charge A 12V Battery?
For a 12v battery, you’ll ideally need a panel of 200 watts to charge a 100ah battery — the most common 12v battery size. Given that a 200-watt panel can produce around 60 amp-hours per day — on a sunny day under ideal conditions — you should be able to fully charge a 100ah battery with a 200-watt panel in 5–8 hours.
Solar panels can generate up to 20v, much higher than the 12v required by a 12v battery. This can lead to overcharging, permanently damaging your battery. The best action is using a charge controller or regulator between the panel and battery, which regulates the charge current and keeps your battery healthy.
