Pretty much any solar panel will be able to charge a 100Ah battery. It just depends on how long it will take. Here are some examples we calculated along the way: A 100-watt solar panel will charge a 100Ah 12V lithium battery in 10.8 peak sun hours (or, realistically, in little more than 2 days, if we presume an average of 5 peak sun hours per day).
50-watt panel, 100-watt panel, and 120-watt panel As a result, we need 2 x 120-watt, 2 x 100-watt, or 4 x 50-watt to cover your 180W solar panel to charge a 100Ah battery. Some recommended solar panels: 100 watt solar panels, foldable solar panels and flexible solar panels.
As we can see, a 400-watt solar panel will need 2.7 peak sun hours to charge a 100Ah 12V lithium battery. If we presume that we get 5 peak sun hours per day, we can actually fully charge almost two 100Ah batteries (or one 200Ah battery).
More importantly, the number of solar panels you require depends on how quickly you prefer to charge your battery. But, generally speaking, a 100 Ah battery would call for a 180W solar panel to fully charge from 50 percent DOD presuming 4.2 peak sun hours a day. On a bright sunny day, it will require eight hours to charge fully.
The 100Ah 12V lithium battery will need (we have calculated this in the previous chapter) 1,080 Wh to be fully charged. That means that a 100W solar panel can fully charge a 100Ah 12V lithium battery in a bit more than 2 days (10.8 peak sun hours, or 2 days, 3 hours, and 50 minutes, to be exact).
As we see from this chart, a solar panel will need to add 1,080 Wh of electricity to this battery in order for it to be fully charged. Now, let's take a look at the sizes of solar panels that can generate this electricity: The most common solar panel sizes are 100-watt, 200-watt, 300-watt, and 400-watt panels.
