Hello, After running a simulation you have access to the "Detailed Results". In the "Tables" window, you can generate a table like the one in the beginning of this thread with E_Grid hourly averages

Hello, sorry about the intrusion, but how i can generate Monthly Hourly averages for E_Grid?

Hello and welcome ! The first steps of how to import custom weather data into PVsyst is explained in our Help in the following link: https://www.pvsyst.com/help/meteo-database/import-meteo-data/custom-meteo-files/index.html Kind regards

New to Pvsyst here. I'm wondering how best I can import custom weather/solar radiation data into Pvsyst - could you share your best practice? Thanks.

Sorry, I can't understand that. Please send us your full project, using "Files => Export project" in the main menu. Send it by e-mail to support@pvsyst.com, and tell us in which variant you have this problem.

Sorry I don't really understand what you want to. The Ohmic losses can be defined in the Detailed losses window

Why not group this "separate loss" with inverter clipping, near the center of the loss tree, rather than placing it at the bottom of the loss tree? Thanks.

Bonjour, Dans vos exemples, l’inclinaison du toit est de 30° et 10° respectivement, et les panneaux sont-ils installés directement sur le toit incliné ? Dans ce cas, il n’est pas possible de réaliser une simulation bifaciale, car peu ou pas de lumière atteindra l’arrière des panneaux. Si les panneaux sont installés sur un toit plat avec des tables inclinées à 30° ou 10°, la simulation bifaciale est possible. Dans ce cas, l’espacement entre les rangées devrait être supérieur à 1 m si la table mesure près de 4 m.

Ok，I wonder if our software can be considered this.

Dear, indeed, the total current should be considered.

Bonjour, Je suis en train de réaliser une comparaison entre un système bifacial et monofacial sur plusieurs types de structures dont: une toiture inclinée à 30 degrés et une autre inclinée à 10 degrés. Or, mes résultats pour la toiture à 30 degrés ne sont pas cohérents car il y a une différence de productible entre bifacial et monofacial que je ne devrais pas avoir vu que les modules sont très proches de la toiture. De plus, pour la toiture inclinée a 10 degrés je n'ai pas ces différences. Je pense que la différence vient de la définition du système bifacial. Comment ça se fait que les schémas soient aussi différents alors que les paramètres sont les mêmes ? Par ailleurs, les scènes 3D sont identiques, mise à part l'inclinaison du toit et des modules. Comment est-ce que je peux obtenir le même schéma, c'est à dire une ligne linéaire mais avec une inclinaison à 30 degrés ? Ceci n'est qu'une hypothèse donc n'hésitez pas à me dire si vous pensez que cette différence vient d'ailleurs. Toiture 30°: Toiture 10°: Merci!

Thank you for your response. The problem persists even when I move to the next page and select the default value. Regards.

Dear sir： For the bi-facial module system , when calculating the cable loss of strings, should the current on the rear side of the modules be considered in our software？ thanks！

hey PVsyst. tabbing through the albedo table no longer works correctly. this is an issue after .14.

This concerns the inverter at the output of the battery pack. On the next page "Self consumption", please define the "Max. discharging power". As a first step, you can ask the default value proposed by PVsyst according to your consumption profile (checkbox on the right).

Hello everyone, When I enter the parameters for a self-consumption system with storage, an error appears that says: 'Inverter Definition: The output nominal power is not defined for a Sungrow battery with AC coupling.' I don't know what parameters I need to enter or where this parameter is located. Thanks in advance

In a project you can create multiple variants (both in version 7 and 8). Since the results will be for the complete system, you have to define your sub-system (for instance one inverter at the time) in separate variants. Thus, in the system window etc., define only 1 inverter and run the simulation. You can then make another variant of your project with the second inverter etc.

For your suggested workaround, how can I do that in PVsyst 7?

Hello, At the moment, PVsyst only provides yield and performance results for the complete system as a whole. Viewing results per inverter is not yet available (though it is on our roadmap). If you need results for each inverter separately, the current workaround is to simulate each inverter as its own variant.

Is there a way for me to view the result of a simulation per inverter stated in the System? For instance, the project has three inverters. I want to see the simulation result for each inverter that I placed in the csv file (time series data). Thank you.

Dear Andrés Fernández, Please email us also at support@pvsyst.com : your PVsyst LOG files (using menu <File> <Export logs>) your project files (using PVsyst menu <Export projects>) so we can try to reproduce the issue you reported. Best regards.

Thanks to this article I solved my problem.

OK， u are welcome

Hi Michele, 🙂. Thank you so much for the swift response. Yes, I was also confused by the same thing. I have shared the project file via email, as requested. Your assistance and guidance is really appreciated.

Hi, this is strange. NS axis trackers (whether 3D scene or using the “unlimited trackers” optimization) should work without issue. Can you send your project (use the export button in the project window to generate a zip archive with all necessary files) over to support@pvsyst.com ? Or share a snapshot of the disposition of your 3D scene. This will allow us to look into it further.
