I read the top link (bottom one didn't work), very interesting, but still no concrete answer. It seems people have had good experiences, and others terrible experiences.
I guess it depends on your outlook going in. I look at everything in life the same way, the answer is neither black nor white, its usually somewhere in the grey area.
It probs takes more work, and cost a little more than advertised, but it may work given some trial and error.
I just don't see why a liveaboard can't build their own solar pannels, for much less than what a standard pannels from ie:Sharp costs.
It'd be interesting hearing from a Sailnet member who's tried it, for some reason i trust people on hear more than from some random site.
