That's one point I was making with my fuzzy math repeater
example. :-) I think the Wili card radios in that repeater system
will operate down to 7V.
I may need more than toys if I tried to use legacy 48V stuff and the
resultant voltage conversions.

The best way to design an off-grid radio system is to take advantage
of every chance you find to avoid having to generate a watt in the
first place.
Two drop-in replacement, high-efficiency voltage regulator devices
that can help to that end:

Am I missing something?
24 (hours of sun) * 60 watts = 1,440 watt hours of solar power
produced.
12 (watts) * 24 (hours in a day) * 33 (days) = 9504 (watt hours) not
1,440 of power consumed.
Working backwards starting with 1,440 watt hours to burn:
1,440 watt hours / 12 (watts) * 24 (hours
Don't forget that there is some inefficiency in the battery and some
self discharge. So you don't get a watt out for every watt in. Also
don't forget that if you're doing this on a budget you're probably
using batteries which are made to deep cycle often so they won't last

I'm not sure I buy into your math. If I have a repeater site that is
pulling 1A @ 12V, then it is consuming something like 12W, right? If
I have 60W of solar panel (2 toys) then when conditions are optimal,
I have 48W left over to charge the battery.
Lets say I am REALLY north, and the panels
http://www.altestore.com/store/ is where I get my solar panels. That
panel looks like the 48v one they sell for a similar price.
Here in the north, I wouldn't bother with anything less than 100w of
