@s.ryberg I moved the tutorial proposal to a new topic so we can discuss it here. Thanks for your comment. Having your do-a-thon after this tutorial session sounds good. We are also open for and interested in a tutorial from you. Which tool would you like to present? If you joined we might drop the pvlib tutorial and focus on showing how to download weather data using the feedinlib and how to use the windpowerlib, depending on how much time you need.
