The statement was made that a system with panels in series could be dragged down by a poorly functioning panel. A system with panels in parallel would not be affected by a poorly functioning panel.
Not exactly correct.
In a series arrangement, ALL the current flowing goes through ALL of the panels. If one goes partially open (gets a high resistance and low output), it might severely limit the total output well below the capacity of the remaining good panels.
In a parallel arrangement, one panel going totally dead only removes the capacity of that panel and leaves the others unaffected.
