Jean-Yves' solar trike

I built my solar trike in 2017, to participate in the Sun Trip. Since then, I use it in everyday life, to go to work, for walks and travels. As I am a cabinetmaker, it was natural to build the load-bearing structure of my solar panels in wood. I chose red cedar for its recognized qualities in marine and its lightness (mixed structure wood – aluminum profiles).
Based on HPvelotechnik trike, I built 3 "Sky Blue" solar trikes that are currently in circulation.
