I am going to install a solar panel with charge controller but with 2

position, which is not desirable.
What say you all?
The price difference between a single and a duo is $45 vs $169.

After a ton of research, I've come to the conclusion that solar on a
sailboat is nearly worthless unless you can mount huge arrays pointing
all different directions with multiple controllers.
That said, the new tech stuff coming down the road may prove somewhat
effective.
