The Google Maps Platform Solar API is a service focused on helping
accelerate solar and energy system installations. The Solar API generates
detailed rooftop data based on Google's extensive geospatial data and computing
resources in order to evaluate rooftop solar energy potential.
Why use the Solar API
The API accepts requests for three endpoints:
buildingInsights: This
service endpoint returns insights about the location, dimensions, and solar
potential of a building.
dataLayers: This
service endpoint returns URLs for raw solar information datasets for an area
surrounding a location.
geoTiff: This endpoint fetches rasters
with encoded solar information, including a digital surface model, an aerial
image, annual and monthly flux maps, and hourly shade.
This data can help users:
- Remotely design a solar power system
- Reduce solar site assessment time
- Prioritize installation locations
- Create more accurate proposals
- Increase customer conversion rates
- Provide insightful details to educate consumers
Solar API country and region coverage
See Solar API supported countries and regions for the latest
coverage details, on a country-by-country basis.

To learn more about the capabilities of the Solar API, check out the
Solar API demo web
app. You can
also optionally reuse the
code
used to build the demo in GitHub.
