I am having trouble with measurements on PVsyst when I imported ground data as CSV file. All of the lengths of my field are longer than actual size. Also I have bigger area according to PVsyst's measurement tool. I created the csv file as it says in the pvsyst help file.
In addition, all of the lengths are measured in the field by Topographical Engineer so I have approved results in terms of calculations and other stuff.
Thank you.
