Dear PVSyst Forum, I wanted to ask how the time interval is defined for energy output and other For example: energy output 1100.0 kW from 08.07.2023 at 08:00 corresponds to the average of energy output from 07:00 to 07:59 or 07:00-08:00? Furthermore: Is it possible to display the energy yields E_grid with decimal places in the CSV. File to be displayed? Thank you!

Hi, i have some similar results. it would be interesting why these parameters change

Hello dear forum, I would need the hourly yield simulation of different PV system sizes for a case study. So for example hourly yields of a 1 MWp, 5MWp, 7MWp etc. until 30 MWp (same location, same components). I would like to avoid having to start a new simulation for each a new plant size. Do you have an idea how it is possible to calculate the yields with a simplified function (f.ex. in excel)? E.g. simulation of a 1MWp plant, simulation of a 2MWp plant --> average of the deviations of the hourly yields and thus build a function, how the yields change per MWp. I appreciate any help! Kind regards

Hello dear forum, I have my own radiation and temperature data from a measuring station. I would like to check if my measured data "make sense" or are representative/qualitative enough. Is this possible via PVSyst? Thanks for your help.

Thank you for your answers but I didn t understand correctly. How would it works with the timestamps?

Hi, I want to import 10 minutes own measured data. PVSyst interpolate 1 hour data. Is it possible to simulate with 10 minutes data? Thanks for your help!

Thank your for the answer. Does PV Syst then average the 4x15 minute values? So is it still possible to import only 1-month data and simulate with it (no yearly record)?

Hello, I have a measuring station consisting of a pyranometer. I would like to import my measurement data into PVSyst. Unfortunately, I only have measurements over a period of two months. Is it still possible to import only this period and simulate with it (no yearly record)? My records are in 15 minutes time intervals. Is it possible to simulate in this temporal resolution? Or are only hourly measurement series accepted in PVSyst? What are the minimum parameters I need for a simulation? Global radiation GHI and outdoor temperature? Thank you very much for the help, which I appreciate.
