I purchased a small flexible solar panel from Silicon Solar Inc.
Their web site advises that the panel is "perfectly suited as a 12V
battery charging solar solution." Just what I need for trickling the
12 volt starting battery for my dinghy. The solar panel produces 7.2v
100 mA.



A friend, who is an engineer, informed me that I am wasting my time.
He says I need 12Volts from the solar panel to charge a 12 volt
battery. Thus the
7.2V will not do it.



Who's right, the manufacturer or my friend?

Must be the pocket version. You need something around 3 foot by 5 foot,
shoving out 13 volts min.@ 1AH.
