If the solar panel produces more power than the battery can handle the battery can overcharge and be damaged. As a matter of fact it s probably not enough to maintain the battery except under ideal conditions a 12 volt solar panel must have an open circuit voltage of at least 17 volts to effectively charge a 12 volt battery.
