Solar powered F650GS (sort of)


After ordering my 23mm socket from Northern Tool (for my oil plug), they sent me their gigantic catalog for Fall/Winter 2012. Thumbing through it last night I came across this. The geek in me wants to waste $24 on it and try it out.
The practical side of me knows that I park 99% of the time in my garage or a parking deck at work. Maybe I could mount the panel outside my garage and run a the leads into the bay?

Hi Bella,
you haven't copied in a link, so WE can't see what the $24 relates to? I assume its a solar gizmo? can it fit any bike other than the GS?

There's nothing showing as a link or picture in your post, but it sounds like you're talking about a solar trickle charger/battery maintainer. The good ones are good, the bad ones will fry your battery. The cheap ones, and it sounds like your talking about a cheap one, usually don't have a voltage regulator in them. Most of the small panels will put out ~19V in full sun in the cold. That's enough to drastically shorten the life of your battery when it sits there and bakes at that voltage for hours a day. The better solar battery maintainers will have at least a primitive charge controller that will clip the voltage to either ~13.8V (for something that thinks it's a float/trickle charger) or ~14.7V (for something that thinks it's an actual charger). It's very important that there's some kind of solar charge controller.

Well 1.5 Watts is not much (about 100 ma). You probably would want the better part of 1 amp to charge the battery
.
Something with 10 - 15 watts would be much better.
Is that right???

A very good and comprehensive website to get to know all about batteries!
http://batteryuniversity.com/learn/

I've not looked up your query on power input, as I couldn't access the above website for 15 mins! it must have crashed. will look later.
