I was sent this link from a Twitter discussion on solar. They are using lithium batteries for their sailboat.

10 amps @ 24 volts = 240 watts.

An EP Carry:https://www.electricpaddle.com/If we have a Salish 100 this year, he'll be doing it again in something a little bigger (based on a C-Lark hull), with room for more solar panels.

With the newer solar panels on Amazon, I see 10 amp at 24 volt in a size that fits Surprises aft deck. In fact 2 panels ( 21 by 41 in. ) will fit easy and still open as designed for access. My cruise speed uses about 10 amp on the battery, so two panels ought to do, even on slightly cloudy days. With my two 24 volt batt. packs, that could equate to running as long as I could stand to sit and cruise. The panel cost is now down to $ 70. 00 each -- which is just about what a battery costs at bi Mart. With my heavier duty fork lift # 27 size, that's about enough to fill in the gap even better, for safety's sake on the water.
