The great thing about groups such as this is the terrific exchange of good ideas, like this one.

Greenhouses overheating are an issue even up here in Northern Vermont.

What I've been thinking is: Since the sun is high in summer, low in
winter and heat rises, then why is a glazed ceiling necessary at all ?!

Why not a solid insulated roof with say a couple of solar wells/tubes ?

This would lower construction and maintenance costs, increase heat in
winter and block out sun in summer....
