Battery capacity is measured in ampere-hours (Ah); small 1,000 mAh AAA takes about 22.8 minutes to charge and big 120 Ah batteries take about a good 2 days (46.08 hours, to be exact) to charge with a small 100-watt battery. How sunny it is (secondary factor). The more sun you get, the quicker will the 100-watt solar panels be charged.
To calculate the charging time of a solar panel, you can use the formula: Charging Time (in hours) = Battery Capacity (in Ah) / (Solar Panel Power (in Watts) * Charging Efficiency (in decimal)) Where the charging efficiency is a decimal value representing the percentage efficiency of the charging process. 1.
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:
100-watt solar panels are considered small solar panels. They are, however, rather useful when charging batteries. To determine how long does it take to charge 12V batteries, we need to calculate the output of 100W solar panels. Output, obviously, changes depending on sunlight (solar irradiance).
To charge a 24-volt battery with a 300-watt solar panel, you’ll need 3.4 hours of direct sunshine. It is dependent on the solar cell quality. At the same time, electricity generation has environmental implications, and you should include the location and weather while calculating everything.
Thus, a 100-watt solar panel, on an average day, will produce 375 Wh of electricity. This equates to 31.25 Wh when broken down hourly. Having established that a 100-watt solar panel produces an average of 31.25 Wh every hour, we can deduce the charging time for any 12V battery.

Solar Charge Controller Sizing Formula | Easy Explanation
For example, for a 100W, 12V solar panel: 100W / 12V = 8.3A. 8.3A x 1.25 = 10.4A. So for this single 100W solar panel, select a charge controller rated for greater than 10.4A array current. For multiple panels, perform the same Max Array Amp calculation above for each panel and sum the results before applying the 1.25 safety multiplication.
