Faults and Fixes
Why is my solar panel not producing its rated output?
The rated figure describes laboratory conditions; real output on a boat is set by shading, angle, temperature and the type of charge controller. A single shadow line from a mast or shroud can pull down an entire series-connected string.
Why it works this way
Declaring the panel faulty before measuring is premature — in most cases the installation rather than the panel is the limiting factor.
