My biggest concerns are the rolling resistance on the hub and the availability of sun.
Dynamo hub or solar panel.
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.
If you want to charge your laptop on the road solar panels and batteries are your best option.
I m trying to weigh the benefits of a solar panel over a dyno hub while racing the td.
The two products i m comparing specifically are the shimano dynamo hub and the guide 10 goal 0 solar panel.
Solar solar has become more and more accessible with many brands popping up and competition means good prices and more features.
I ll be powering 2 headlights a garmin edge 800 and an iphone.
A 20w would recharge a 20000mah powerbank 2 3 times per sunny day.
My preference is to use dynamo hubs.
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.
