[QUOTE=Mark Johnson;633486]Our boat
has been solar self sufficient for the last 15 years and it works great for us! Having had both solar and wind
, I found it to be both quiet, and produce more amps, averaged out over a year. We got rid of our wind
gen years ago, for this reason... It made room for a 110w panel on the stern.
If space makes this an impractical goal, you could let the engine
run in the morning do half the work
, and let the solar top them off over the day. No matter the size of the alternator
, they are not great for topping off batteries
, as their extra amps cannot be absorbed when batteries are near the top.
We replaced our voltage regulator
with a BALMAR
charge controller. This makes your alternator
act as a programmable 3-stage charger
. It also drops the alternator power (engine drag) if the power is not needed.
