Just doing some research
on MPPT controllers. Interesting case to be made, particularly for larger installations, to have different panels controlled by different controllers. This way when some panels are shaded by clouds etc for example, and some not, then the controllers for those different groups of panels will optimize differently -- resulting in more total output than a single
controller for all the panels. Read that some manufacturers/installations are starting to consider building MPPT controllers into the panel itself so that each panel can be optimized individually.
Also reading about different MPPT algorithms. Such technical things are not usually humorous, but the common name of one algorithm "Perturb and Observe" I found funny
-- sounds like a great bar game
