This is your chance to construct solar powered object. Teams that enter this challenge need to construct a solar powered device, think model house, ferris wheel, phone charging tree, machine, car — whatever you want — as long as it is powered by solar!

All entries will be evaluated on their thoughtful, creative, and resourceful design, innovation and complexity of the circuitry, your reflections on the construction process, and what you may have learned about solar power.

Each month we will select a few of our favorite devices from all the posted entries. This devices will be added to our library of featured solar devices.
