After 20+ years of just turning off, I just started the same "tendering" with my boat this year, experimenting with two different ones to see which I prefer.
Testing one of those $6 tenders and one of those solar 1.5amp battery mantainence panels, both from harbor frieght. See this Spring how they each performed.

Now the solar thing got me thinking.....I have a massive flat spot on the roof that starts right at the back wall of where I keep the boat. I was thinking a large panel on the roof dedicated to just the boat would be sweet.

How would one go about regulating the voltage after the battery is charged from a solar panel?

And since my windshields are pretty jacked....considering the cost of replacements....integrated solar panels instead of a windshield was my other "I wish I had more time" ideas. Fold them down to deflect wind for driving. Flip them up when you're parked.
