Before going to the time, effort, and expense of making a dedicated solar dehydrator, try the following three niches, present at many sites, and see if they might be adequate to your purpose. 
 1. A vehicle parked in the sun.  Windows cracked or not depending on weather, night/day etc.
 2. An unused greenhouse or similar space, such as during the summer.
 3. The attic space of a house.  All of these niches can be improved by setting up a fan to circulate air over and around the trays, screens, or tied bundles of food or herbs.
