I have two power poles that shade across my solar trackers. One is directly to the south of #2 that only goes across during the winter months. I have two 6 panel arrays on each tracker and when the shadow hits it the array output goes to zero while the shadow is crossing it, about a hour. The other pole is to the west and it does the same to two trackers, slowly moving across both arrays late in the afternoon shutting down output from two arrays for about an hour and a half. I have 4 six panel arrays on each charge controller, as long as at least one array is in full sun the MPP will be tracking on it and the lower voltage on the shaded arrays will not contribute much if any to the output of the charge controller. There is not much I can do except just live with the lower output during the shading. If you are installing a new system I would avoid shading at all cost, it will pay off in the long run.
