JamesLenton Posted Thursday at 07:41 AM Posted Thursday at 07:41 AM Hello, Please can you help explain why irregularities like the one shown in the image attached occur in PVsyst? In this instance power drops from 15 MW to 0 MW in 30 minutes, mid-day in the summer. To me this seems impossible, even with partial cloud cover. Could be a result of poor weather data, however I experience similar things with Meteonorm and PVGIS.
Linda Thoren Posted Thursday at 01:55 PM Posted Thursday at 01:55 PM Hello, To better understand the results, you can consider adding additional parameters—such as irradiance—to assess whether a drop in production is due to variations in weather data or other factors. In the Advanced Simulations, you also have the option to export hourly data as a .csv file, allowing for deeper analysis of any relevant simulation parameters.
