sam.ley Posted April 16, 2020 Share Posted April 16, 2020 Hi,I have a large number of licenses, and a growing limitation we are finding is the inability to run true sub-hourly simulations at 15 or 30 minute increments. For long-term yield of a PV-only plant with a fixed price PPA hourly is fine, but adding storage, variable market pricing, and working in regions with extremely variable irradiance means additional time fidelity is needed, and I have to go to other tools to get it.We have high quality weather data coming in now at 30 minute intervals for nearly every location on earth, and site-specific data down to 1 minute intervals. I'd love for PVsyst to keep up with the improvements in meteo resource data, especially if we are pending a new major update with additional costs for annual licensing.Thanks - Sam Link to comment Share on other sites More sharing options...
dm2014 Posted April 17, 2020 Share Posted April 17, 2020 I/we fully support this topic/request for an update. Many other tools on the market now support 1/5/15/30 min data which is incredibly important for capturing variable irradiance. For example, running a test/evaluation in alignment with IEC 61724-3 will not be very accurate without subhourly considerations, particularly at higher dc/ac ratios.Thanks,Dan Link to comment Share on other sites More sharing options...
rscott4563 Posted September 17, 2020 Share Posted September 17, 2020 Is this something that is officially on the PVsyst development plan, is there a roadmap or timeframe for this to be implemented?It does seem a bit ridiculous that we are in 2020 and still only have a resolution of 1-hour in PVsyst modelling...

Rinaldi Posted October 21, 2020 Share Posted October 21, 2020 Dear PVsyst team,is there any planning in the software development within next 12 months to start providing sub-hourly calculations ? We have a real need for such feature in our project, i.e. 5-minutes time resolution, possibly even down to 1-minute depending on the project progress.Best regards, Link to comment Share on other sites More sharing options...
