Since PVsyst utilizes 2D model, it is not able to provide a calculation for rear side mismatch, rear side shading and shed transparency factors sadly. But as far as I learnt from the many whitepapers, conference papers and articles, these values vary depending on the system type. To illustrate, for a 1P tracking system with the 100*100 mm torque tube (height: 2m), shading factor, mismatch factor and shed transparency should be 5.7%, 4% and 3.1% respectively. These values come from another software that uses 3D model.
