A bit late for our adventurer Manos, but if you're planning on laying up your car and you don't want to disconnect your battery (ECU reset...), Halfords sell Ring and Sealey solar panels.
And these aren't the sort from ten years ago; we've got a 200mAh one that is keeping Jinxy charged. It's overkill, but is powerful enough to not only keep the battery conditioned, but also run a 12V dehumidifier. I strongly recommend getting one if you have a car that you only use occasionally.
