Hi PVSYST Team, Thank you for the implementation of the sub-hourly simulation feature in PVsyst 8.1. It is something many of us have been waiting for. I am currently trying to generate meteorological data with a 15-minute resolution using different sources in PVsyst, and I have tested the following approaches: Pull with Meteonorm 9: it seems to only allow hourly data or minute-level data. While minute data could technically work, generating datasets at that resolution can become quite heavy and time-consuming for large projects with complex topography. Synthetic data generation: https://www.pvsyst.com/help/meteo-database/synthetic-data-generation/execute-generation.html From what I can see, this option also only allows hourly or 1-minute frequency. At the moment, the only way I have found to work with 15-minute data is by using the “Import a custom file” option. With the new import tool it is possible to specify a 15-minute timestep, which works well if the dataset already exists externally. My question is the following: Is there any option within PVsyst meteo databases (e.g., Meteonorm or tool synthetic generation) to directly generate sub-hourly data with a specific timestep such as 10, 15, or 30 minutes, instead of only hourly or 1-minute resolution? Or is importing a custom dataset currently the only workflow for these intermediate time resolutions? Thanks in advance for any guidance.

Hi Michele, thanks for the answer, I understand that this process of assignment between tracker and orientation is manual for the moment or it can be done with PVsystCLI. looking forward to the next updates!!

Hi PVSYST Team, My goal is to model trackers with the terrain follower feature, for that I need that each tracker (table) or subtracker depending on the type of TF can be associated to a specific orientation, with the objective that each tracker considers a different POA and thus be possible to quantify the losses by TF (assuming that I would do the electrical calculation at the module layout level). My specific question Is it possible to make this association of tracker to orientation? and if yes, what is the correct procedure to do it? Thanks!

Hi, you are right , we are using a step of 1º (120 simulations for a range of movement from -60 to 60 and what we do is to adjust the angle of the backtracking to the lowest absolute angle and before it, to avoid that a wider angle gives shadows. I also think it can be caused by interpolation, I will make some tests. we are a tracker company and we are internal validating the accuracy, the effect that has 1,2,3...5º degree deviation of the backtracking angle

Hi to all forum members I am looking to simulate backtracking behavior as a summation of fixed structure items. What I mean; Perform a simulation with bactracking enabled to know the angle at each tracker time. Then perform a batch simulation with a sweep of all the positions(angles) that the tracker can be in. Then process the information in a separate document, select the E_grid if the angle of each hour that comes from backtracking match with the respective angle in the batch simulation, and replicate this whole year The problem I have is that when comparing the first and the last hours of the day, they give very different results to those obtained with backtracking, the rest of the numbers are kept in similar parameters. Any idea why for the same time and the same angle, is the E_grid for backtracking different than as a fixed structure? Any help is appreciated
