Plan for the Sun & use its power efficiently

Go beyond solar inclination. Rely on precise 3D shadow visualization.

Used by over 25.000 people worldwide every month.
Solar panels on roofs

Due to their two-dimensional nature, solar cadasters are usually limited to the solar potential of roofs alone. Vertical surfaces, such as facades or balconies, are ignored.

Thanks to its 3D data sources along with 3D visualization, Shadowmap is able to show their solar potential as well. All while respecting potential shadowing by surrounding buildings and terrain.

Lightyear One solar car

One of our favorite utopian use cases: The solar car. Lightyear is working on one that can reach a maximum of 12 km/h. Not as a measure of top-speed but of recharging: through the Sun.

Sono Motors, another manufacturer, will release their first solar car in 2023. Shadowmap helps drivers of cars like these to find sunny parking spots and solar-efficient routes.

Farmland in the sunset

Total insolation is a crucial factor in agriculture and plant life in general. Different plant species require specific amounts of sunshine hours per day, which becomes difficult to estimate in hilly or mountainous areas.

Shadowmap's 3D terrain and visualization gives immediate insight and predictability. On a smaller scale, you might want to use your terrace, balcony or garden for growing fruit, vegetables and herbs? Shadowmap helps you find the right place for your urban gardening patch by simulating the incidence of sunlight at different times of the year.
