Solar Panels
My 14 Panels are all connected together in series. If one panel gets shaded (or damaged) it drags the output of the whole chain of panels down. If each panel has its own clever widget that doesn''t happen. My son has 2 chains of simple panels on opposite sides of the roof pitch. Lies to children level of explanation but I hope that helps.
