Solar kiln with separate chamber?

[69bronco]

I've been considering the layout for a new shop. My thoughts are using a solar collector on the south wall that I could duct into a well insulated (kiln) box. Nothing to big, say 1000 to 1500 feet capacity. Sized accordingly  or perhaps making the collector a little oversized. The optimum set up would be able to redirect the collectors intake and exhaust into the shop in cool weather, when not drying lumber. The collector could even pivot a little for maximum exposure all year. I may be all wet on this one, but it's been rolling around for awhile. Let me know your thoughts.

Good idea.  It is certainly good from a technology standpoint.  Appreciate that the energy needed for drying is much greater than the energy needed for heating without drying.  So, even with low winter solar input, you should get some useful heat for heating, but not for drying.  But, with the kiln being isolated from the collector, if you need some drying in the wintertime, you can use external heaters.  Make sure the kiln box is well insulated.
