If you are into solar drying food, then pieces of tin could be used for that. I make a shelf up on legs to lay the food pieces out on, but instead of the shelf bottom being wood, it is screening. This shelf is positioned 1 inch below the tin roof. The sun heats the metal roof, thus drying the food pieces below on the screen shelf. Works great for me, better than some more complicated solar dryer setups.
It's never too late to start! I retired to homestead on the slopes of Mauna Loa, an active volcano. I relate snippets of my endeavor on my blog : www.kaufarmer.blogspot.com
