This talk is a deep dive into the open-source website openpv.de - prepare yourself for lots of open geodata, physics-based solar irradiance simulation, some shady WebGL code, and insights on how to get funding from the German government for your open-source project.
We will look at the available open data of 3D buildings, laser scans, and elevation models from Germany and how we navigated through the jungle of governmental open datasets. Having these valuable datasets allows us to do fancy things - like building a browser-based tool for solar potential simulation. This includes the task of performing physics-based simulation in WebGL, a nice problem we planned to solve in one afternoon but that ended up taking several weekends.
In the talk, we also share about the evolution of our project and our experience along the way. We started as a simple free-time project, but evolved and even received public funding from the German Prototype Fund in the end.

Come and listen to our talk if you
1. think about installing your own PV system,
2. love open geodata,
3. want to see some fancy 3D simulations in the browser.
