I am replacing my
current dingy
davits with a new arch. This means, that my
solar has to be redone as well.
As the arch will be the same width as the
davits, I will more or less have also the same space, which on my
boat due to it's narrow-ish transom will limit me to one large ~300W panel, or two smaller ~120W
panels.
Forgetting for the moment the
power difference, what is the pros and cons of one vs two seperate
panels.
I'm thinking of redundancy of two panels, benefit of separate controllers to help with partial shading issues. Any others?
On the other side, two panels will be more expensive than the
single, larger one, especially when two separate controllers is used.
Looking forward to hear from the experts.
