Understanding Solar Panel Types: Familiarize yourself with different solar panel types—monocrystalline, polycrystalline, and thin-film—to choose the most efficient option for charging your 12-volt battery based on space, cost, and performance.
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.
If using an 80% efficient panel, you might increase your wattage need slightly: Adjusted watts: 480 watts ÷ 0.8 = 600 watts. This approach helps you choose an appropriate solar panel wattage to effectively charge your 12-volt battery. Adjust calculations based on unique conditions and equipment used.
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.
