Turns out, 100 watt solar panel will take about 9 peak sun hours to fully charge a 12v 100ah lead acid battery from 50% depth of discharge. how fast should you charge your battery? Deep cycle or solar batteries are designed to charge and discharge at a specific rate, which is referred to as the c-rating.
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:
For example, let’s say your estimated charge time is 8 peak sun hours and your location gets on average 4 peak sun hours per day. In that case, you know it’ll take about 2 days for your solar panel (s) to charge your battery. Besides using our calculator, here are 3 ways to estimate how long it’ll take to charge a battery with solar panels.
1. Divide solar panel wattage by solar panel voltage to estimate solar panel current in amps. For example, here’s what you’d do if you had a 100W 12V solar panel. 2. Divide battery capacity in amp hours by solar panel current to get your estimated charge time. Let’s say you’re using your 100W panel to charge a 12V 50Ah battery. 3.
First of all, you need to start by converting the battery capacity of your solar battery from Ampere hours to Watt hours, ie: Watt-hours (Wh) = Amp-hours (Ah) x Voltage (V) Substituting the data gives you 960Wh for your solar battery. Then, you need to know how much you need to charge your solar battery, i.e.:
300W solar panel generates 1,350 Wh of electricity per day (24h). That’s 56.25 Wh per hour. To fully charge a 50Ah battery from 0% to 100%, we need 600Wh (from Step 1). How many hours will it take to fully charge such a battery? Here’s how we calculate the charging time: Charging Time = 600Wh / 56.25Wh per hour = 10.67 hours
