Part 2: fixed-tilt rows run east-west and face the equator, on ground with one flat plane slope. The table tilt stays fixed from horizontal and rows follow the ground east-west. Design day is 21 December (21 June south of the equator), solar time, morning hours only. Pitch is the horizontal front-edge-to-front-edge distance. A design aid, not a shading simulation. The facing labels are for the northern hemisphere; they swap south of the equator. Slope limits are yours: no universal limit exists.
