Except, as has already been pointed out, you have to space out angled panels much further apart longitudinally near the poles otherwise they block each other. We're going round in circles on this. Consider a relatively modest 1km square patch of such a massive array. At the equator this patch will consist of panels laid out flat horizontally relative to the 'ground', with a 10m patch spaced every 10m (no gap). At 80 degrees latitude this patch will consist of panels angled up at 80 degrees in longitudinal strips. Let's say each panel is a square 10m x 10m. If the next strip towards the equator is placed 10m away from the foot of the strip 'behind' it, almost all of the strip behind will be obscured in it's shadow. In fact the strips would need to be spaced about every 60m instead of every 10m. That's 1/7th the density. Instead of 1 sq km of panel area you'd only have 0.14 sq km of panels.
