Solar panels of any size can be used with a 12v battery, but the panels must have a 12v rating too, and you must use a charge controller. In this article, we’ll be covering the following: If you’ve been wondering about 12v batteries and the right solar panels to use for them, you’ve come to the right place!
A 12V solar panel is used with a 12V charge controller, a 12V battery bank, and a 12V inverter. 12V panels are becoming less common, in favor of 20V and 24V panels, but manufacturers like Rich Solar do still offer 12V solar panels.
For a 12V, 50Ah battery, you would need at least 100 watts of power (preferably from two 100-watt panels).
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.
In general, 12v panels are only available up to a rating of around 200-watts; from there up they are usually 24v or 48v. There are various sizes of 12v batteries available, 100ah being the most common.
