Gurdeep Sandhu's Solar Tree is a portable, adjustable and movable solar 'roof', that is flexible and can be placed anywhere.  It can be placed in the garden or your roof.  When you are ready to move to a new place, simply fold it and transport it.

The only issue that I see is stability.  Will this be strong enough to withstand high winds, when you are not around during the day?  Maybe it can be extended to be shaped like a 'car port' that you can park your 'green' electric car!
