NO HARDWARE NEEDED, ALL PRINTED. Modern Solar Panel Hex Cell Sun Tracker Model, no functioning electronics, its a moveable model for my Renewable Energy class. The model itself can rotate in two different axis, allows for the solar cells to be perpendicular to any direction the sun may be facing. Again this is a model without any electronics, just an educational tool of how a solar tracker might increase the efficency of the Solar Panel. A proof of concept.
