I ordered 2.  One works beautifully!  The other didn't work at all.  I then sent a request to replace and got a new one.  It will only work in direct sunlight.  So when the sun is out the lights work but at night, they do not! What's the point of having light when the sun is out?  I've tried everything to fix it but they will not work at night only during the day when the panel is in direct sunlight.  These are too expensive to have so many issues. I would not recommend - but they are pretty when they do work...so frustrating
