Finishing Touches
Solar Decathlon teams hail from all over the continental United States as well as Puerto Rico, Germany, Spain, and Canada.
Here, a member of Team Spain puts the finishing touches on the roof its modern-style solar home. An inverted glass pyramid outfitted with photovoltaic panels and solar water heating collectors rests atop the house via a ball-and-socket mechanism. A solar tracking device orients the pyramid structure as the sun changes throughout the day to achieve the highest efficiency.
