Hello. I am installing 3 100 watt solar panels
on the railings around the fly bridge of our Tollycraft 37 sportfish. There is a bimini
(almost always furled up) and a mast
overhead so shading will be an issue. My goal was to have two panels
in clear sunlight no matter how we are swinging on the anchor
I can lower the bimini
and the mast
- like I do to go into the boathouse - and then all three panels
are pointing straight up with no shading.
So based on what I've learned here, I want to hook the panels up in parallel if the bimini and mast are up, but in series when they are down to take advantage of the higher voltage in the wires leading to the controller. Is this correct??
My plan was to wire the three panels to two separate 6 position terminal strips and then move the two wires leading down to the controller from the terminal strip that has the panels wired in series to the one where they are wired in parallel.
THEN I thought, why not put a DPDT switch that would switch the two controller wires from one terminal strip to the other.
Does this make sense? Am I introducing too many connections into the system? Is there a better way??
As always, many thanks....
