Solar Panel Specifications

10000 watt Solar Panels?
For my Product Design Coursework I am designing an environment friendly building according to a clients' specifications. I need to find out the dimensions of 10000 watt solar panels. any help would be much appreciated!
Crudely, for crystalline silicon panels today, 10 watts per square foot is a good budgetary number. The actual panel will be smaller, but you will need space for mounting, and there are always obstructions you need to keep away from.
