Site topography or the terrain is one of the major challenges that a tracker manufacturer faces everyday, and often viability of the tracker for a site is decided based on one very key component. Trackers can become difficult to install at grade exceeding ±5%, and typically require relatively flat site conditions. In addition, the recent rise in bi-facial modules requests made it imperative for traditional tracker manufacturers to have a compatible design available for maximum gains from the site existing Albedo (a proportion of light that is being reflected from the site landscape, which can vary anywhere between 5% to 80%).

This report aims to:

  • identify adaptability of each tracker for various terrains (N/S direction only) with the associated material and installation cost
  • show preferable mounting structure for bi-facial modules by using geometric data from CAD models and by using PVSYST - a widely used software to confirm production differences for both orientations (portrait vs landscape).
