The main solution to this problem is to preserve your fruit and vegetables so you can enjoy them through the winter months. In my opinion, one of the best ways to do this is to dehydrate the food. You can purchase electric dehydrators, but why spend money on an electric dehydrator and continue spending money on the electricity it uses, when you can make a solar dehydrator pretty cheaply that costs nothing to run.
If you’re interested in building your own solar dehydrator, check out the video below. Also check out the link at the bottom of the page for more information on building a solar dehydrator.
