Solar Trailer
My Solar Trailer
Bought a kids cloth trailer for $50 used, stripped all the fabric down to the light aluminum frame. Me and my dad created the wooden structure around a 100w flexible panel. I got the panel on Amazon for $100, and another external 50w panel to get a full 2amp 48v charge under direct sunlight assuming 75% effeciency. The wall outlet charger for my bike charges at 2 amps, so this is 1:1 in comparison. Also the cheaper non-flexible glass panels may be cheaper, but they weigh 20lbs instead of 2lbs. Mounting it to my RadWagon 4 required welding and creating a custom hitch from some steel. I get 6-7 amps @20volts with the sole 100watt panel on the trailer when sunlight is directly above in the most ideal conditions, which is a little more than 2amps 48v, meaning this setup charges faster than the wall outlet in ideal conditions.
