Wally Its all in how you see it. A solar panel may be slow but it has no moving parts. How often do you need to start the motor a second time after already starting it the first time?
A properly sized start battery has enough energy stored for three complete start cycles before it is depleted fully. A single start on a good motor will deplete less than 10% of the stored energy. Does it make a difference if that energy is replace in 10 minutes or in an hour or two? And who says the solar panel has to be only 10 watts. You could get a bigger one. Mind you; a 10 watt solar panel is perfect as a trickle charger for maintaining a battery bank against self discharge over long periods. Hot tropical climates encourage more electro-chemical activity and thus self discharge in any storage battery.

The starter battery is isolated, but a 10W charger will take quite a while to recharge the battery after starting, since that's a large draw, it sounds inefficient if not ineffective - or does the battery still have the alternator charging it?

Which becomes totally unnecessary if you isolate the battery. Becomes a case of less is more.

If it is isolated, it has to have a combiner to the house bank or from the house bank if the alternator is used as a source to both banks. **************AOL Search: Your one stop for directions, recipes and all other Holiday needs.

Read my lips: (From a previous post) A small solar panel (10W or less), dedicated to the starting battery, solves the problem.
