MPPT will cause more shading, but if the gains outweigh the losses, cool (and with only 9 panels calculating that shading will be pretty fast). My first thought

MPPT will cause more shading, but if the gains outweigh the losses, cool (and with only 9 panels calculating that shading will be pretty fast). My first thought was that making each panel articulate is a tough engineering problem when weight is a concern (but with smaller/more efficient panels like you suggest maybe it evens out on weight.).
