Solar panels cost $3.00 to $4.50 per watt installed on average, with homeowners spending about $3.75 per watt before factoring in available solar incentives. A 6- to 10-kW solar panel installation costs $12,600 to $31,500 after the 30% federal tax credit. [pdf]
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. 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]
