Slope-Aware Backtracking for Single-Axis Trackers
Closed-form equations of the true-tracking angle, backtracking angle, shaded fraction, and orientation angles of single-axis solar trackers installed on arbitrarily oriented slopes are derived. These slope-aware adjustments are necessary to successfully prevent row to row shading in arrays with nonzero cross-axis slope. A tracker rotation modeling procedure comprising these equations is provided.
