Mike continues to be hard at work and the rooftop module for the hybrid solar dryer is now finished. The sides are marine plywood and the top is sheet metal painted black. (Cutting out the holes for ventilation was the most difficult part!) On top is a solar fan and a turbine vent for sunny and/or windy days.
These pictures show front and back views of the roof module mounted on the upper cabinet. The solar exhaust fan is white and faces south; the turbine vent is a bronze color on the other side. These two units will ultimately mount atop the lower cabinet.
The next step is stainless steel mesh shelf and runners, and then we will just need a few nice hot days for testing purposes!
