Here are some charts on what size solar panel you need to charge 12v and 24v 200ah lead acid or lithium (LiFePO4) battery. .
The maximum charging current for a 200Ah lithium battery is usually 100A and the ideal charging current for a lead-acid or AGM battery is 50A. Charging your battery at a higher. To charge a 200Ah battery, use four 120W solar panels in a 12V system. For a 24V system, you will need two 200W panels. Charging time depends on sunlight and panel efficiency. Accurate calculations lead to effective and reliable charging with solar energy. [pdf]
