This one looks neat, but I think I can propose a better one. :) It could be a tower, externally black in color, with the south-facing side transparent or windowed. The interior under the window should also be painted black. Instead of one rack, multiple racks of food could be installed.
Why?
a tower develops ascending airflow, while a horizontal box does not, this helps ensure that moisture does not re-condense but leaves
with a tower system, you can also dry foods that would degrade from sunlight (gather energy at the bottom and deliver it to a closed top part)
I even built one and used it to dry kale chips, but it was too tall - wind kept pushing it over.
You could try anchoring it with guy wires or burying the bottom portion in the ground - I had a similar probem with my dehydrator until I sank the base about 8 inches and added some rocks around it.
