A well thought out design for a solar lumber drying kiln.  The article includes good design, construction, and performance detail.

The design uses a solar air heating collector with a flow through absorber.  The collector comprises the full south face of the kiln.  Air is circulated though the absorber with 3 12 VDC fans driven by a single PV panel.
