This is the solar oven in the winter position. For summer see this post.
It is open without the cover or reflector so that you can see the 6" oval roaster and the 5"round pot inside.
Note that it is standing on its narrow end so maximize solar exposure to the low winter sun.
This is the solar oven in the winter position with the cover and reflector on.
You would use it in this way from November to the solstice on March 21st.
You can still cook fish or light vegetables like zucchini without the reflector but just about anything else will not get hot enough. So the reflector is essential in the winter.
