I guess it depends on usage, but is there a general formula as to what percentage of panels you optimise for winter, vs summer for offgrid @Svarky ? With the panels that aren’t optimised for winter, do you optimise them for summer, or have them in between, or does it depend on the roof pitch you have to work with?
