Anyone using a solar ceiling fan outdoors for 2+ years? Curious how they actually age

I’m looking at adding a ceiling fan to a covered patio and have been comparing regular outdoor fans with solar-powered ones. The solar setup is appealing, but I’m less interested in how well it works out of the box and more interested in what happens after a few summers outside. One I’ve been considering is the ventallion solar ceiling fan. The separate solar panel makes sense for my patio since the roof itself stays shaded, and having a built-in battery means I could still use the fan and light in the evening.
My biggest question is longevity. With something like this, is the battery usually the first thing that becomes a problem? How well do the fan motor, housing, and solar panel hold up after years of heat, humidity, and temperature swings?
I’d rather buy something once and maintain it than replace the whole setup every couple of seasons. For anyone who has had a solar ceiling fan for a few years, what would you pay the most attention to if you were buying again? And is a replaceable battery something you’d consider a must-have?
