Would it make sense to install blocking diodes for the parallel strings in the summer and remove them in winter? It would be nice to have a way to flip back and forth as needed but I don't see a very feasible way that wouldn't be cost/efficiency prohibitive.Been reading this thread the last couple days here and there and noticed that my panels did exactly what was described here. The bottom 2 110's are series together, but then the middle 2 are in parallel together and then in series with the top 220. Top 3 group in parallel with bottom 2 group. Those seem to have heated the bottom 2 panels, a happy little accident in design, since the bottom panels are most likely to have water and ice shed onto them from the top panels
