Solar Assessment of Roofs (SolAR)
SolAR is an intelligent geographic database containing every roof in England and Wales that is potentially suitable for the installation of solar panels. It contains a variety of information about each roof that determines the level of suitability for that roof, including size of usable area, pitch and aspect.
The SolAR database has been compiled from up-todate high-resolution stereo aerial photography and other geographic data, including digital surface models and solar radiation data. SolAR can be linked to address databases allowing buildings suitable for solar panel installation to be identified. It has been designed in an open format to allow incorporation into almost any software, from Microsoft Excel and Access to more advanced GIS, and SQL. It can be used within Google Earth and even through web interfaces.

|
|
A simple point database containing all attributes.
| |
The database also contains the geographic location of the centre of the usable roof. Supplied as an Excel spreadsheet of other database formats, GoogleEarth KMZ or GIS point file (e.g. ESRI, MapInfo, DWG)
|
|
For the advanced user the data can be supplied as 3D polygons depicting the size of the roof.
| |
The polygons are accurately and geographically located in a 3D space. They are attributed with the same information as the point file. Available in GIS or CAD formats (e.g. ESIR, MapInfo, DWG).
|
|
The data can be supplied in discrete geographic regions (for example a postcode sector, county or region)
|
|
It is possible to purchase data to your own specification, for example only buildings over 30 sq m or with narrow aspect criteria.
