The scene location consists of a latitude, longitude, and time zone. The shade calculator requires this information to calculate sun angles for the shade loss calculations.

When you start the 3D shade calculator from SAM, the location information is automatically populated with values from the Location and Resource page. If you change the location in SAM, be sure to update the location information in the 3D shade calculator.

You can underlay an image of the project site, either from Bing maps, or from an image file on your computer.
