shadow study, sheet 01
No model is trained and none runs. This is shadow geometry and irradiance bookkeeping over the city's own 3D model. There is no ground truth: nobody publishes per-roof generation for Zagreb, so nothing here has been checked against a real installation. Two roofs are comparable with each other because both come from the same pipeline. An absolute figure in kWh of electricity is not, and this page never shows one.
