Solar powered fan for small kiln

Can anyone recommend a small solar powered fan for a small kiln?

The kiln is just a plywood box, 10' x 4' x 2', painted black.
I use it to reduce the moisture content of lumber that is very close to being dry already, and to heat treat wood that might have bug issues, so there won't be a lot of moisture swirling around in there.

I hope to move the box out to Palm Springs at the end of the week. It's hot there. Forecast says it'll be 111° this Saturday. I'm interested to see what the temperature gets up to in that sun.

Any advice welcome, Mark.

I have these in a couple of sheds. The shed is 10 x 12 x 8 and I use two on an end wall with a passive vent at the opposite end. I use them to move just enough air to keep things from getting damp or stuffy. Near-silent, easy install.

I thought about those fans Glenn, but I think they suck air in from outside?
I want to just circulate the air inside the box.
