As well as the movable ones, pointing largely West to extend the generating day almost to sunset, I also rotated the Sharp array on the garage roof to the S-SW a bit. In the early morning, it didn't generate much, as there is some shading from trees to the West. In the late afternoon, the power would drop off too, as the sun soon goes round to an oblique angle. So, rotating it S-SW a bit flattens out the mid-day power curve of the whole system, and extends the peak power generating time longer into the afternoon.
