Use Cases

Built for businesses that need solar intelligence at scale.

From PropTech to CleanTech – teams integrate the Shadowmap API to deliver differentiated features and get a step ahead of their competitors.

Sun Score for Real Estate

A single metric indicating how much sun a property receives

The Sunscore API rates buildings based on their annual direct sun exposure – between 0 and 100. Feed it coordinates, get back a precise score based on real 3D building geometry, terrain, and the sun’s path across the sky. Instantly comparable across any portfolio. Also includes monthly scores, sunlight hours and confidence levels.

Relevant for:

PropTech platforms
Real estate portals
Mortgage tools
Energy assessors

API Reference

Endless applications. Just like the Sun.

Our APIs run on worldwide 3D data including terrain, buildings and vegetation – combined with precise solar calculations.

Shadowmap API Endpoint #1

Check any point for direct sunlight

Determines whether a specific geographical location – at the specified time – is in the Sun or not, taking any physical 3D obstacle (terrain, buildings, trees) into account that could be in the way (excl. atmospheric phenomena like clouds).

As a bonus, you also receive elevation of the provided point and useful sun statistics.

Shadowmap API tells you in real time whether that specific spot is in sun or shade right now, or at any future time.

Shadowmap API Endpoint #2

Sunscore for any building

Provide coordinates for a building and get back a precise annual sun exposure score — based on 3D geometry (terrain, buildings, trees). No building found at the provided location? The API creates a placeholder shape for you.

The metric represents the amount of sunlight the building’s exterior surface receives throughout the year on a 0-to-100 scale: 0 means that no sun ray ever hits it, while 100 means that the building is never in the shade across the year (imagine a single building on the top of the highest mountain).

Additionally, we provide monthly Sunscores as well as confidence levels based on the accuracy of the surrounding 3D data at the given location.

Shadowmap API calculates a comparable metric that represents the amount of sunlight the building receives.
