This conference talk explores the development of openpv.de, an open-source website that simulates photovoltaic potential of buildings in real time using WebGL and OpenData. Dive into the challenges of working with German open geodata including 3D building models, laser scans, and elevation data. Learn about implementing physics-based solar irradiance simulation in WebGL—a task that expanded from an afternoon project to multiple weekends of work. Follow the journey of how this free-time project evolved to receive funding from the German Prototype Fund. Perfect for those considering installing their own PV system, open geodata enthusiasts, or anyone interested in browser-based 3D simulations. Presented by Martin Grosshauser at the 38C3 conference.
