Hi PVsyst, Thanks again for your help on my previous queries. I had a quick question about data export I was hoping you could help me with. So far, for obtaining hourly system output values for the year (eg for calculating possible export rates) I've been using Results->Hourly Graphs->Copy Values to clipboard. This method only allows 100 days export at a time, however, and each data section must be entered separately into excel using the text import wizard, then formatted. I noticed that there's also the option for setting an output file during simulation. However, this requires re-simulation to obtain the file, which will take a long time on projects using 3d models. Is there any alternative method for obtaining the hourly data? (I'm mainly interested in just the energy output.) I think we will be using this process a lot in the future and so any more efficient method would save a lot of time. On a further note (perhaps this is a suggestion), multiple variants of the same project also need separately exporting, one by one. It would be incredibly useful to be able to batch export a whole project's data (eg 5, or even 20 variants) into one output file. Is this possible? Thanks for your time, Iain
