Agrivoltaic Sun-Tracking Canopy — 2D Shadow Map

Solar panels raised above a working field don't just sit there — a single-axis tracker rotates them across the sky all day to chase the sun, and that constant motion changes exactly where the panels' shadows fall on the crops growing underneath. This 2D companion simulator drives the sun's true position from latitude, day-of-year and hour-of-day, computes the corrected optimal tracking angle for a horizontal single-axis tracker, and projects each panel's four real corners along the sun's ray to build an exact shadow quadrilateral on a live top-down crop grid — rather than a coarse east–west shadow band. A second panel plots sun elevation, solar energy yield, crop PAR and the combined Land Equivalent Ratio across the full day, so you can read off the shape of the trade-off directly instead of only sampling one instant at a time.
