Solar charging question

I am having no success finding a solar charge controller for my sailboat. The problem being that I only want a little supplemental charging, say 300 to 400 watts of solar panels, but my battery voltage is pretty high- (20) CALB 180AH cells is 64 volts nominal to be charged at 70 to max 72 volts.To get the PV panel voltage I'd prefer a single panel, but no more than two in series and I cannot find panels of sufficient voltage to allow this. I will need three at a minimum. I do not want to turn…See More

Long Term Degradation of Flexible Solar Panels

Some of you have, or are considering, the very light flexible solar panels with a plastic base that are made in China. These work very well for me, and I have 15 of these panels.  But, they may not last as long as glass covered panels. My first set of four panels has now been continually exposed for 4 years, and is showing serious degradation of the outer plastic coating. This occurred fairly quickly only in the last 6 months. …See More
