Tilting Veranda

I was thinking about how a veranda/patio/porch on the south side (or north in the southern hemi) is very good at keeping the sun out in summer but that is the exact reverse of what you want in winter. So what if you had the veranda hinged at the house and a set of motorized telescoping veranda posts......press a button and the veranda tilted up in winter letting all the low angle sun shine deep into your house, and then lower it at night. In summer you could do the reverse, have it lowered during the day to keep the sun out and raise it after the sun goes down to enjoy those warm evenings outdoors....
