As a rule of thumb, a rating of 15 watts delivers about 3,600 coulombs (1 AH) per hour of direct sunlight. . To charge a 12V battery with a capacity of 100 amp-hours in five hours, you need at least 240 watts from your solar panels (20 amps x 12 volts). A 300-watt solar panel or three 100-watt panels are recommended. Formula: Charging Time (h) ≈ (Battery Ah × V × (Target SOC / 100)) ÷ (Panel W × (Eff% / 100)). Adjust for sunlight hours to find daily charging duration. . Understanding how these panels work can help you determine how many watts you need to charge a 12-volt battery effectively. They typically provide around 15% to 20% efficiency.
