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).
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).
charging time (h) = capacity (Wh) panel wattage (W) panel wattage (W) = capacity (Wh) charging time (h) panel wattage to charge the battery in 6 hours = 3600 6 = 600 W We need a total panel wattage of 600W to charge the battery in 6 hours, and one solar panel is 100W. So, the number of panels we need to charge the battery in 6 hours would be:
Here you have it: A single 300W solar panel will fully charge a 12V 50Ah battery in 10 hours and 40 minutes. You can use this 3-step method to calculate the charging time for any battery. Let’s look at how we can further simplify this process with the use of a solar panel charge time calculator:
If the battery is completely discharged it would take 13 hours to replenish it. A 100W solar panel can produce 108.2 amps in 13 hours, enough to recharge the battery. It would take two and half days assuming there were six sun hours available each day.
charging time = 2880 ∗ 65% 300 ∗ 93% = 1872 279 = 6.7 hours ≈ 7 hours To make our estimation even more accurate, we can factor system losses into the formula used in the previous method: battery charging time (h) = battery capacity (Wh) ∗ DoD (%) adjusted solar output (W)
