The three solid walls will be covered in whatever I can scrounge together, probably plywood primed and painted. It'll be free standing. I decided against solexx for this project since I want something more substantial. I'll be using either triple wall poly or else glass. I went to the local ReStore (Habitat for Humanity) and they have a great selection of large glass. It may be that I could get together enough to build the whole front wall in glass, which would be really nice. Sliding glass doors.
The north wall will have double stacked 55 gallon barrels of water. In the winter the sun will shine on the barrels. In the summer, the barrels will be entirely in the shade. Check out the pictures of solar greenhouses here:
