Space and energy are two commodities that will only increase, in both expensive and demand, as our population grows. This solar power concept from English designer Gurdeep Sandhu features solar panel arrays that would fold down when not in use in a saw-horse design. The system provides a space-saving, solar power source for residential and commercial consumers who have multiple uses for  their small rooftop, garden or yard.  Open it during daylight hours and fold it down at night. Need to play some soccer or sunbathe?  Just fold the panels down. I presume the installation would be easily moved or retro-fitted to rotate for maximum solar exposure.
