thank you for your reply.

Dear sir, may i know hoe to export the expected energy production to excel as hourly basis? Regards,

Hello, I am trying to upload TMY3 file to the application but I face an issue as below. I uploaded copy of the file in the below link for you kind review and advice what are the mistakes in the files. https://falghanim.sharefile.com/d-s635388b83bb847968d66bc24acd267f6 Appreciate if you could give a sample of the right TMY file. Thanks.

Hi, Is it possible that we import 2D CAD file layout to PVsyst? Thanks

Thank you for your reply. Is there any video with the steps of importing from CAD 2D or 3D to PVsyst?

Hello, Is it possible to import a layout to the PVsyst from CAD file or Google earth? If yes could you please clarify the method? Thanks

Hello, Thank you in advance. My I know how the global irradiance on the rear side is calculated 10.72%(285Kwh/m2) considering the the site irradiance was 2229KWh/m2.

Greetings, May I know how to import site layout from CAD file to the PVsyst 3D simulation and if there is tool to define the table configuration, and pitch then ask the software to fill the layout with certain No. of tables as defined in the subarrays?

May I know what is the use of the TMY file in that case? It has meteorological data of the specific site so how we can use it in the project design please?

Hello, i have TMY file on excel and i tried to covert it to CSV file and both files attached in the below link. https://falghanim.sharefile.com/d-s6bfcb20ff3c64db2a56e07163f6b210f when i came to upload the CSV file to the PVsyst, i received the below message : Could you please clarify the right method to convert the attached TMY file to CSV format to not face such error? Thanks

Could you please clarify what is the most recommend DC/AC ratio for utility scale plants? It's risky to increase the DC/AC ratio which makes the PR guarantee is not achievable with the irradiance increase in the future. So, what is the min. And Max. Ratio to limit the risk of the PR in the OM years for utility scale projects?

May I know how to calculate the plant Auxiliaries using excel? Also, do these Auxiliaries losses are covering the night loads?

When the plant has different transformers, we have to generate through the inverters reaction power so the inverter capacity will be increased to cover the reactive power of the plant after the inverter. Should we mention the revised inverter capacity in the system design through the simulation process or we just mention the inverter based on the active power only??

For the shading losses,is it possible to calculate the shading losses by equations or it needs 3D simulation? For the utility scale plant which will have high voltage transformers, how we could calculate the losses in that transformer? How to estimate the plant Aux. Losses?

Also may I know how you simulate the bificial modules in the PVsyst?
