Big solar for small boat

[GTom]

Correct, a frame could probably hold even 2 of those large household panels which I most likely don't need. Tilting is single axis I guess?

The boat goes to Scotland in <2years, I don't expect too much solar there. Btw, 100Ah = 1.2kWh provided you also have a 12V system

Sigh

Not sure where you are getting all of these figures from that you keep quoting. 100w is next to sod all KWh if it's cloudy and throwing it down with rain. It's also about .5KWh on a Sunny day, so your statement above is meaningless. These are my panels https://www.photonicuniverse.com/en...-for-Motorhome-Caravan-Camper-Boat-Yacht.html

With a max output of 5.62a can you explain how you get 1.2KWh from one of these in a day ?

The information i have given you is real World. I have a Discus, it is fitted with 260w of top quality solar panels, configured how i said, connected to a Victron MPPT controller. The boat lives on the East coast. The yield figures i have quoted are real World, logged by the solar controller.

1.2kWh is my (a bit overestimated) consumption, not production. Fridge, autohelm, all bells and whistles. Doesn't have to be 100% covered by solar, but the more the better. I definitely don't expect kw-scale production up in the North.
