No... but I'd like to hear other folks experiences using solar float
charging...

Solar float charging seems to work well. I haven't tried it myself
but have heard a lot of success stories. A small, inexpensive panel
is all you need unless there is a lot of leakage in the electrical
system.

Recharging a trolling motor is a different matter since serious amps
are required. You have to calculate how many amp-hours need to be
replaced, and how much daylight time you have available. Most people
also recommend derating the panel capacity by at least 50% to allow
for all the inefficiencies that creep in to the process.

There's a local guy who has a jon boat with some small 8 or 9 hp. two
stroke with no charging system, ...pull rope and mag. He has a
trolling motor and one battery. I dont' knwo f its a trolling battery
or a car job, but he got tired of stringing an extension cord out to
his boat shed and hooking a battery charger on the thing, so he got a
cheap harbor freight solar panel and clipped it onto the posts. I
though, "this'll never go" but he's said he hasn't' put a charger on
his battery yet. and says it's always "hot"

OK, this guy goes fishing about every saturday afternoon. But I dont'
know how much of a serious workout his trolling motor and battery go
through.

But........

Voltage might also be an issue. A lot of the larger trolling motors
are either 24V or 36V and that might drive the price of the solar
panels, plus any necessary isolation hardware, through the roof....

Say, $3000 for 2 panels delivering 270W (@ 12V) times 2. That should
yield about 45 Amps.... that might even be enough to just run the
motor! However, that doesn't account for any power loss or control and
isolation hardware.http://tinyurl.com/ml6h6v

Things would be easier for a 12V application, but I suspect that the
Amps required would be proportionally higher.

I use a 15 watt solar panel to recharge a deep cycle battery on my
sailboat and to keep it topped up between uses. This works well for
charging between uses but when running the boat, the diesel does most
of the charging if the battery is heavily used.

I found a few websites - look the figures from my 24Vdc motor, added a
few things up and it comes to roughly $4,000 and that's conservative.

Think I'm going in a different direction. :)
