Here's the solar lumber kiln. Here you're looking Northwest. The kiln's South-facing wall and South-facing roof are glass. On a sunny day the heat gets above 140 degrees F. in the summer. If we insulated the walls and the cold side of the kiln we'd get close to that in Winter. Air-drying cures lumber at one inch of thickness a year.

Our kiln cures lumber at an inch per month. We keep air circulating with two little fans driven by a one-amp photovoltaic panel. When we reconfigure the shelving the kiln's capacity will quadruple or better. The way it's been since we built it 1990, we just dump stuff on the floor. Very inefficient -- but it works.

The hot day, cool night cycle conditions lumber much better than a constant temperature electric closed kiln.
