Well, the only reason I can think of that it wouldn't work would be the ability of the limited winter sunlight to recharge the batteries enough to give a sufficiently long period of artificial light. As far as the light intensity, they have a lot of ultra-bright LED solar lights now.
Your location might make a difference. You don't state where you are, but probably the further north, and therefore the shorter the winter day and the dimmer the sunlight, the less likely it will be to work. And, if you live someplace like I do, Michigan, with persistant fall and winter gloom due to lake effect clouds, and snow falling on the solar collectors and blocking the light.
