For a 100Ah, 12-volt battery, you’ll need 1,200 watt-hours to fully charge it. Divide this number by the average sunlight hours per day in your area to determine the required solar panel wattage. If you get 5 hours of sunlight, you’ll need at least a 240-watt solar panel to recharge this battery adequately after daily use.
Calculating the right solar panel size for battery charging involves assessing your energy needs and understanding the factors that affect solar panel performance. Start by identifying the devices you want to power and their energy consumption. List each device along with its wattage and the number of hours you’ll use it daily.
