Drying fruit is a great way to preserve it, and offers a new way to enjoy an old favourite. You can easily do it in your own yard with a dedicated solar dryer.
Instructables user velacreations shared his plans for a solar cooker, but you can adapt the concept and build yours however you want. The basic idea is to create a box topped with sheet metal that can absorb sunlight and disperse heat to the fruits arranged on trays inside. A screened opening is also necessary to let the moisture escape. Painting the inside black can also help trap some heat. You should aim for an internal temperature of about 60 degrees for 7-15 hours, depending on the fruit. If it's too warm, try cutting a larger vent to generate a little more air flow.
Most people probably won't build a dehydrator quite this big, but the detailed instructions should give you an idea of how to make one that suits your yard.
