Suntrack Backtracking System

Backtracking algorithm main specifications are:

1.- Avoids shadowing among panels/trackers
2.- Embedded in Suntrack controllers.
3.- Fully automatic during tracker lifetime. No manual or time adjustments.
4.- 2 axis or 1 axis backtracking option.
5.- South orientation offset configurable.
6.- Easy to configure with Suntrack Configuring PC software
7.- Increases power thrughput.
8.- Improves power plant lay-out (land area/watt)

Backtracking Algorithm Eficiency. Basic info for study

1.- Location: Latitude: 38º (for example Spain)
2.- Panels size: 50mx 2m
3.- Fix panel optimal inclination: 36º
4.- Fix panel row oriented : South. East-West row
5.- 1 axis row: North-south oriented. East ->West movement

Backtracking Algorithm concept




Example:Backtracking Efficiency 5 meter gap


Backtracking Algorithm Efficiency OPTIMIZER

We could calculate the best lay-out of your tracker for maximize the global efficiency (land area and production). Example: tracker with and without backtracking algorithm and delta_y = rows separation in meters:
