Help with solar build

[scot wolf]

I'm thinking about starting a solar build. Starting with a modded U of W  design that will have a 50sf collector and 12' long. Will 2- 16" Wally world fans be enough?  Also, I've been kicking these panels around in the barn and was wondering about how to use them in in build. They are steel wrapped foam panels about 29"x 39". Any ideas?

Scot, I would not use those panels, its just so much easier to frame the kiln at 16" centers and use the right size fiberglass bats.

The fans...if the blades are plastic, forget it.
There must be some other low cost fans out there that wont melt .
