        "note": "Shadow length = object height ÷ tan(sun elevation). The lower the sun, the longer the shadow — which is why solar layouts are designed for the worst case, the winter-solstice low sun. When the sun is not square to the rows, the shadow cast across the row direction stretches by 1/cos(azimuth difference), so off-noon and off-south the shading reaches further.",
