To charge a 200Ah battery (2,400Wh), use a solar panel with at least 600 watts. This is based on 4 hours of daily sunlight (2,400Wh ÷ 4 hours = 600W). Remember to account for efficiency losses; a less efficient panel will need more wattage to reach the same charging goal. [pdf]

A 10-watt solar panel can charge a 12-volt 7-amp hour battery in about 3.6 hours if the conditions are perfect (i.e. full sun at the equator). In more realistic conditions, it will take longer because the sunlight is not as intense and there are usually some clouds in the sky..
How to calculate charging time of battery by solar panel? Divide the battery’s watt-hours by the panel’s wattage, then add 20% to account for power loss. Convert battery capacity from Ah to Wh by multiplying with voltage. Factor in 20–30% efficiency loss from heat, wiring, and controllers. [pdf]
