The overall charging time will vary depending on the state of the battery. The charging pace of a solar panel can be affected by the sun’s location in the sky. During summer, the charging pace will be faster when sunshine shines directly on a panel. On overcast days, charging cycles are slower.
You should also install a charging controller to prevent battery overload. The maximum cell size you should use a 40 watt solar panel is 200ah. There are no technical restrictions, but 200ah may be too much. Even if the battery board generates 17 amps of current every day, it takes 12 days to charge the 200ah battery.
