I'm trying to run batch simulations for N-S single axis trackers with a tilt of zero. All I want to do is vary the pitch. In the Parameter Specification, 3D shadings parameter I select Pitch E-W between trackers and backtracking activated. I did notice that the parameter word "Backtraked" had been misspelled in the output file. I get the message: Warning: The shading table has not been computed in the results I ran this in batch mode with just one data point for the pitch: PVsyst simulations Batch mode;; Simulation parameters and results; File Created on 01/11/16 10:24;; ;; Project ;;;Sample PVsyst;; Variants based on;;VC2;ATI_Duratrack_HZ 2.1 MW DC;; ;; ;; Ident;Trackers;Backtraking;Simul;Error;E_Grid; ;Pitch EW;;Comment;;MWh; ;[m];Y/N;;;; ; SIM_1; 4.00;Y;ATI_Duratrack_HZ 2.1 MW DC ;Warning: The shading table has not been computed;4082; Thanks for your time, Mike Reed
