I agree that battery plus solar panel is probably about the same weight as a dynamo. Plus it's far more useful. But I keep thinking they were built for different purposes. I don't do extended touring these days, and if I did, I'm not sure what I would do for power. I do like my dynamo for lights, because I just get on and roll without needing to think about how charged my headlight is.
