This is a small solar kiln I made last summer. The fan is also solar powered. I have sliding vent covers that aren’t installed in the pics that help regulated drying rate.

What a good idea on the fans.
I’ve had one for about six years but my fans plug in so I have to set them up on a timer.
The only problem I had was once early on when I dried a small load and didn’t reduce the collector area.
With two fans and the vents closed I still cooked a bit of my wood.
Since then I’ve paid closer attention to the sq footage of collector uncovered / fbm in the kiln ratio.
They are a great way to dry wood in a fast but controlled way.

Congrats on yours.

Shipwright I am on my third charge and had read about the sq footage of collector uncovered / fbm in the kiln ratio so I was careful with it but with the varying weather here its hard. I got impatient with this load and opened the collector right up then we got 4 days of really hot and dry weather and I cooked the top board. From your experience is the wood just good for fire wood now or will it be workable if I let it sit and come back up to 12% or so??

David it is 10’x4’x4’ if I were to build another one I would go taller than that I might even raise this one. It gets real tight when I am loading and checking the MC of the front stack is hard when its full. There is a lot of good info online here is a good article from American woodworker this one is designed to be packed up and stored which may be useful is space is an issue.

I have some more links saved from when I was planning mine so if anyone is interested I would be happy to share what I have.

For every 10 bd. ft. of capacity, you need 1 sq. ft. of solar-panel or roof area is the rule from the article I linked and the angle of the collector is relative to where you are located.

I am far from experienced when it comes to kiln operation but I did a lot of late night reading when I was planning this one.

Here are the rough plans and material list (number of sheets for roofing should be 3):

What happened to mine (it was arbutus(madrone)), was that some areas sort of collapsed, near knots and the like. I was able to cut around those spots and use most if it.
... but you do have to pay attention.

Great idea…that’s something I think would work real good where I live. Much better than letting the log dry out a couple years. What part of the County do you live in?
