The open data behind our maps.
SolarFleet's maps, site locations and weather model use open data. Each source, what we use it for, and the attribution its licence asks for.
Postcode and place locations
Sites placed from a UK postcode, or a town or suburb name, sit at that postcode's or place's centre point. The coordinates come from postcodes.io, which publishes the ONS Postcode Directory and OS Open Names. The map marks these positions as approximate.

Northern Ireland (BT) postcodes are not looked up. ONS releases their coordinates under separate Land & Property Services terms, so sites in Northern Ireland are placed from typed coordinates or an OpenStreetMap address search instead.
Map tiles
The fleet map and site maps draw OpenStreetMap data, either as OpenStreetMap's own tiles or as CARTO's Positron style.

Address search
In Site settings, “Find location” answers a postcode from postcodes.io (above). A search with no usable postcode is sent from our server to OpenStreetMap’s Nominatim service.
