The solar panel has the advantage of being usable for other sports and with other bikes should i ever upgrade.
Dynamo hub or solar panel.
If you have dynamo lights already do yourself a favour and grab a power supply to start charging your devices.
Just like a laptop panels and batteries are not lightweight or space savvy.
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.
I m trying to weigh the benefits of a solar panel over a dyno hub while racing the td.
My biggest concerns are the rolling resistance on the hub and the availability of sun.
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.
The two products i m comparing specifically are the shimano dynamo hub and the guide 10 goal 0 solar panel.
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.
You can choose different sizes for different power a 10 15w panel is more packable and will keep most users well charged.
