Greenhouse advice please.

Our new garden is south east facing and I want to place the greenhouse at the top of the garden next to quite a high shed. 

I have worked out that in the summer it will get the sun for all the afternoon.  Is this enough light do you think?

Mine doesn't get any early sun, but still gets baking hot  (when there is any sun of course )

Doesn't matter -- same difference. 

In fact a hedge will protect it well and you'll find that helpful in the winter time
