Here's V2 of my solar bike trailer. We plan on doing some overnight rides on our eBikes. We will need to bring along our tent and other camping gear. Since we have a bike trailer, I thought I would add solar to it. I designed it so the panel will aim towards the sun when possible. It charges my Ryobi batteries and my Bosch ebike battery 🙂
