I like that idea. It would take two or three to get any headroom. Might be easier to erect a framework and bend the panel for a roof, then cover with a tarp. Panels are 16 feet long so if you built the walls 10 feet apart you could spring the panel to rise three feet. You could also add on as needed. Panels are less than $25.00 so two would give me twice the space for not a lot more money. Snow might slide right off.
