Na. Its a North facing one. Not the best, but thats all I got

It probably gets about and hour of direct mid day sunlight.. But I did notice that the status shows as charging (stable orange light) even when there is bright day light..
Math or not - it probably does qualify for a "better than nothing solution" although categorizing north facing as "not the best" is an understatement, more accurately "the worst"
good luck - if it keeps the battery alive during the winter it was an easy fix. I think I would worry more about it being stolen than the parking structure owners complaining
