I have actually used both 2 different sized solar panels and a lithium backup battery on Ragbrai. Whether any of these will work for you depends on: How many days long is your ride? How sunny will it be and how much time will you have to do a solar charge? How many devices you need to charge. For solar charging. The first lesson is you can not charge ...

Check out GoalZero, they make a bunch of portable solar products. While it's a little bit pricy they are quality products that will last. My buddy uses one when we are gone racing and have no access to electricity, and it works quite well for phones and other small electronics. I have also seen, but don't really know much about, people putting these on ...

Your weight is used for calculating your power to weight ratio (W/kg). Weight of bike/clothes/other gear is not taken into consideration. It is considered that these things weight about the same for every "pro" cyclist. So you should use your own weight because everybody else is doing that. This way you can compare your results with your competition.

At the time of this posting, the solar chargers out there aren't very robust, unless money isn't a factor. If you're going to be camping each night, try the biolite camp stove. I haven't found anything that can charge my iPhone faster and it's relatively cheap, much cheaper than a good solar charger. ...

Remember, very few road racers are giving it hell from a standing start. The vast majority of the time they are traveling at a fairly high rate of speed as they approach the end of the race (With the lead out for the sprint, positioning, etc), so the need to jump multiple gears is very limited. Other times where quick acceleration is needed is to jump a gap ...

Change gears before you need to You can do this two ways. Change to a higher gear before you stop. Get out of the saddle when you start. You'll accelerate faster and shouldn't need to change gears until your doing 30 kph (20 mph) or so. Or change gears regularly as you start, say every 3 or 4 pedal strokes. 1, 2, 3, change. 1, 2, 3, change.

To weigh in my experience, I did the US Southern Tier last summer and did not need solar chargers. I did consider them, though. My requirements were to keep my Nexus4 on 24x7, while GPS tracking my route. This is a pretty power intensive application, and I was able to do it by just buying a big 15,000mAh backup battery and charging it whenever I had access ...

I believe you are asking two different questions: the first, how to use Coggan's Power Profile; and the second, given power at one duration, how to extrapolate and predict power at other durations. But first, an historical aside: Coggan's Power Profiles pre-date the publication of his book with Hunter Allen so really should be thought of as Coggan's own. ...
