Benjamin has created a series of videos showing how he converted a swing-set to serve a dual purpose. He beefed up the structure with some 3/4″ conduit which he flattened the ends on and used it for cross bracing. A couple of solar panels we mounted to the roof and the wires were safely routed through conduit to a remote location when he uses the energy to charge his electric motorcycle.
The charging rate varies significantly proportional to the amount of sun. He was seeing 2 Amps on a cloudy day and has witnessed up to 7 Amps. Check out the videos after the break.
