Hi, Will there be any update in PVsyst to support Subhourly data, as Subhourly (10min/1min) Meteodata is available it will be great if we can get subhourly energy values.

Dear PVsyst Team, After recent updates was unable to see spectral correction loss /Gain in PVsyst loss Diagram. Please let me know if i have to change any settings. Or else if that's a bug to fixed. I have a report with version 6.79 which needs to be evaluated & i have the updated version so can some one please address this. Thanks

Dear PVsyst team, I was going through hourly generation and noticed that LID loss in hourly generation is reducing every hour till December. But in Real Scenario LID loss occurs very initial stage. For other Electrical analysis what is the accurate method to be followed.

Thanks Nil, From start i just download data from interactive map, even i had the coordinate. This is some thing i didn't know, thanks for the information .

Dear Team, After updating to 6.77 version i am having problem with downloading data, The interactive Map page is is not responding for the new coordinate i wish to download data. Please let me know if any changes to be made in my system to run it without any issues. thanks

Hi Team, I m trying to Run a simulation for floating solar, so What are the parameters to be considered. and if we change Uc & Uv values or Albedo what will be the result. and any chances that PVsyst will include Floating solar parameter. \ Thanks

Dear PVsyst team, we are facing this issue cannot run near shading animation, if we try to do PVsyst getting shutdown. so Please let us know if any problem is there with respect to OS or what configurations needed in system to complete our task. Thankyou

Thanks for the Quick reply Andre, Hope the next update will make my job easier. Thankyou.

Hi all, After updating to 6.6.6, i am unable to take IAM values for most of the modules, I am confused if i am making some mistake or any error from PVsyst end. Please let me know Thanks

Hello, I am unable to download data from PVsyst, attaching the screenshot of the error.

Hi all, We have a case where there is 2 strings 21 in each string with different module makes , so the voltage flowing through the strings will be some where 800 & 815 respectively. so will there be any flow in reverse current in the 800 V string. if there is any reverse current flow, what value of current will be flowing. Until what voltage difference, the reverse current may flow.

We are looking for relation between Ir-radiance vs module current taking Temperature and voltage into consideration to get module output power, is there any formula available to calculate manually for this relation.

Thanks for the valuable information. We have a case where there is 2 strings 21 in each string with different module makes , so the voltage flowing through the strings will be some where 800 & 815 respectively. so will there be any flow in reverse current in the 800 V string. if there is any reverse current flow, what value of current will be flowing. Until what voltage difference, the reverse current may flow.

How can we make sure that the given OND and PAN files are Trusted, Is there any Third party certifications.. and is ther any chance that PVsyst Validating them.

default Voltage drop across series diode in PVsyst version 6.39 is 0v where as same in updated version default is given 0.7v. 1.Why there is incerase in loss. 2.Does it refers to bypass diode or the reverse-blocking diodes. 3.As most of the newer modules dont have reverse blocking diode, why have we set the default as 0.7v rather than 0v which may make more sense.
