Dynamo Hub Or Solar Panel

Solar solar has become more and more accessible with many brands popping up and competition means good prices and more features.

Dynamo hub or solar panel.

My biggest concerns are the rolling resistance on the hub and the availability of sun. Just like a laptop panels and batteries are not lightweight or space savvy. If you want to charge your laptop on the road solar panels and batteries are your best option. A 20w would recharge a 20000mah powerbank 2 3 times per sunny day.

I m trying to weigh the benefits of a solar panel over a dyno hub while racing the td. If you have dynamo lights already do yourself a favour and grab a power supply to start charging your devices. The solar panel folds down quite well still a little bulky but it easily fits in my frame bag or is left exposed when needed. My preference is to use dynamo hubs.

However the dynamo hub seems more reliable for generation and doesn t rely on having a rack or flat surface on which to mount it. The solar panel has the advantage of being usable for other sports and with other bikes should i ever upgrade. I m looking at around 2k aud for wheel sets myself and partner to be built with dynamo hubs while not a major issue i m concerned i ll get little in the way of mah for my investment when i already have a solution.
