Thank you for your interest in our Capital Hill Residence. The pergola is open to the elements so the fan is rated for a wet location. Here is a link to the fan: http://www.ceilingfan.com/Emerson-Curva-Sky-Ceiling-Fan-p/emcf152orb.htm

Good luck with your project. Mark

You are quite welcome.

where is the wiring for the fan? do they make battery powered or solar?

The wiring is in the recessed area above the pergola. As far as I know there are no solar fans. Here is a link to the fan: http://www.ceilingfan.com/Emerson-Curva-Sky-Ceiling-Fan-p/emcf152orb.htm I hope my information is helpful.
