Hi, I am unable to import SolarGIS data into PVsyst version 6.47. Although the same file is easily imported in 6.39. Please let me know why this is happening.

Can anybody explain this?

Hi, I am trying to create a shading scene for a site which is having hills nearby. Can you please tell me how to go about this?

Can anyone explain this?? I too have similar issues.

I was trying to simulate a 50MW project and have recived error (refer screenshot attached). Can anybody tell me what is causing this?

Thanks Andre. Can you explain this to me? "Now since the version 6.36, it is possible to specify a representative sub-part of the system (for example the input of one only inverter), and during the simulation the shading calculation will only be performed on this sub-system, but applied to the full system. This concerns the "Linear shadings calculation", and the calculation "According to modules strings". This tool doesn't apply to the "Module layout" calculation." How can I simulate the input of only one or two inverters? I am not able to find the option. It is a single axis tracking plant.

Ok. Now I modelled a shading scene for full 50MW using about 192000 nos. of modules. But whenever I try to calculation shading factor table, the program stops responding. What could be the possible mistake I am doing? Is it because I am trying to model a very large system? Is it possible to do modelling for a 2 MW block using two inverters per block keeping the system size as 50MW?

I have designed a 50MW single axis tracking plant using two sub-arrays (with 310WP modules and 315WP modules). Now I want to create a shading scene for it. How can I do it? Whenever I try to create a shading scene for 1MW block it gives error saying :shading area is lower than pv modules area".

I have made a 3D scene for single axis tracking PV array. It gives an error "You have deifned a tracking plane in the shadings scene. All tracking parameters should match the orientation definition. The axis orientations don't match". However, I have selected Tracking array: horizontal axis E-0 for PV planes. What could be the possible reason for this error?

I am simulating a 50MW ground mounted project. I am a beginner at PVsyst. Can anybody help me how to define detailed losses in PVsyst? What are the inputs to be given?

How to do array sizing for a 50MW AC plant using 310Wp (50%) & 315Wp (50%) modules and 1MW inverter? What is the planned power to be considered? What should be Pnom DC/AC ratio to get 50MW AC output.

Hi, I have to design a rooftop for a site in Northern Hemisphere (India). Roof is north facing. Please suggest how I can do simulation in PVsyst for the same. I am not able to select north direction in PVsyst. Also, I m concerned about the generation.
