I saw an interesting video of a guy who rewired some broken solar panels to kind of bypass the bad spots:
It seems to me the same rewiring might reduce the effects of partial shading on an array.
I'm thinking of using two parallel panels with a cheapo MPPT charge controller (looking at mpt-7210a and CKT-EV-600).
It seems like the panel diodes get removed in the video. Is that a good idea?
I would love to see a schematic for a 72 cell panel and an explanation of what the diodes do when they are working and when they are just along for the ride.
I want to try to get the maximum performance out of a small array so if I can reduce the effect of shading, that is great but I don't want to create a dangerous electrical situation.
I'll use the best wire and connectors I can afford to maintain it's weatherproofing and minimize IR drop (no ugly hacks).
