Solar Tracker Row Backtracking (2D)

Interactive 2D side-view simulation of single-axis solar tracker rows: watch true sun-tracking cause real inter-row self-shading at low sun angles, and see how the backtracking algorithm computes a reduced tilt to trade cosine loss for zero shading loss.

Utility-scale solar plants pack thousands of single-axis trackers into tight rows to maximize land use, but that same density creates a problem: near sunrise and sunset, a row tilted to face the low sun casts a shadow straight onto its neighbor. This 2D side-view simulation computes the true sun-tracking angle from real solar geometry, the exact shaded fraction of each row from 2D shadow-ray projection, and the backtracking correction real tracker controllers apply to trade a small cosine misalignment for zero inter-row shading. Adjust the time of day, latitude, row spacing and panel width to see the trade-off play out, and compare backtracking against direct tracking side by side.

⚙ Under the hood

Interactive 3D simulation of single-axis solar tracker rows in a utility-scale solar farm: watch true sun-tracking cause inter-row self-shading at low sun angles, and see how the backtracking algorithm trades off-normal cosine loss for zero shading loss.
