Creating Measured Data Analysis Variant

[vrajeshpatel]

I am not sure if this is the intended purpose but I was trying to take existing variant from a grid connected project and run through measured data analysis tool. The software lets me create a new variant from VC# files and it even lets me do simulation and save but when I go back the saved CM0 variant disappears. After looking at the project folder, I noticed that it actually created another VC# variant rather than CM0.

I am using Version 6.26 (Here are the steps)

1. Create a project under Project Design - Grid Connected. Save a variant.

2. Go to Tools - Measured Data Analysis - Create variant From - Choose the previously saved variant in step 1(VC0 file).

3. Run simulation/save variant.

4. close PVsyst

5. Open the measured data project you saved in step 3.

If this is not intended purpose, it would be good feature to have instead of recreating new variant from scratch which is time consuming when you have lot of sites to analyze.

Thanks.

Passing from a "normal" calculation version to a comparison calculation is not simple.

However we will probably deeply review the Measure-simulation Comparison tool within some months, and I put this suggestion as a topic on which we should pay attention.

Thanks for prompt response Andre. I believe this will be useful feature.

Hi,

I am following this post and I think this is what I need.

I have solar sites that have been operating for 3-4 years... So I have reliable data. In order to calibrate my PVsyst model I would like to set up a variant with the exact details of my existing site(s). From there, I calibrate the PVsyst model to the actual output of my system. Now, when I want to use the same inverter/Module/Racking combination, all I need to do is use that variant as a base and modify the site location and Module/Rack/Inverter quantities to derive a very accurate simulation... However, at this point I am having a hard time doing this in PV Syst... How would I accomplish this?
