Aidan Dwyer, 13, went to the woods and had a eureka moment that could be a major breakthrough in solar panel design. The 7th-grader ... noticed a pattern among tree branches, and determined (as naturalist Charles Bonnet did in 1754) that the pattern represented the Fibonacci sequence of numbers. Aidan wondered why, and figured it had something to do with photosynthesis. In a pretty innovative experiment, this intrepid young scientist set about duplicating an oak tree, comparing its sunlight-capturing abilities to a traditional rooftop solar panel array. He copied the pattern using a computer program, and built an oak tree-shaped solar array out of PVC pipe. He next built a flat-panel array mounted at 45 degrees, like a typical home rooftop array, and attached data loggers to each model to monitor voltage. Aidan's award-winning essay ... walks you through his experiment design and his results. But the short story is that his tree design generated much more electricity - especially ... when the sun is at its lowest point in the sky. At that point, the tree design generated 50 percent more power, without any adjustments to its declination angle. He determined the tree's Fibonacci pattern allowed some solar panels to collect sunlight even if others were in shade, and prevented branches on a tree from shading other branches. Now Aidan is studying other tree species and improving his PVC model to determine how it could be used to make more efficient solar arrays.
