SunTrace3D
Visualize sun movement across buildings in real-time 3D. Find the perfect spot for solar panels and estimate energy yield for any location on Earth.
Everything you need for solar analysis
Powerful tools combined in one intuitive 3D interface
Shadow Simulation
Accurate sun position tracking for any date, time, and location. Watch shadows sweep across the city in real-time.
Solar Panel Analysis
Place virtual panels on rooftops, calculate irradiance, and estimate annual energy yield with shading loss analysis.
3D Terrain & Buildings
High-fidelity 3D city models generated from satellite data and OpenStreetMap, including terrain and rooftops.
How it works
Three simple steps to solar insight
Choose Location
Search for any address or enter GPS coordinates. A 3D model of the area is generated automatically.
Explore in 3D
Navigate the interactive model with realistic sun shadows. Scrub through time and dates to see how light changes.
Analyze Solar
Place panels on rooftops, calculate shading losses, and get annual energy yield estimates backed by PVGIS data.
