Hi David Thatcher I wanted to ask you for advice on solar panels.
I also thought of putting two solar panels on the boat entrance doors with measures 70x100cm.
Looking at the photo, I think it is the best place to put the two panels, but Bernd says that a cable passing over a photovoltaic panel decreases the charging yield.
Reading your message, I see that you had no problems and were satisfied with your photovoltaic system and I think that the DUO 900 system is the same as your boat, as there are two small cabins.
In my area many have advised me to put a 600w wind turbine. As you can see, I am undecided on what to use between photovoltaic and turbine.
Bye
