The service provides estimates of reduction of efficiency of solar energy installations due to shadows cast by terrain and other objects at a location. Estimates are based on data collected during the Shuttle Radar Topography Mission (SRTM), which created highly detailed images of surface topography. For a specified location, the service can project interference with solar irradiance by naturally occurring and constructed terrain features.
API methods support submission of a location's coordinates to receive an estimate of the relief shadow effect on solar resources there. Shadow effect is stated as a percentage of the day that solar irradiance will be blocked. Methods also provide esimates of global horizontal irradiance and direct normal irradiance under clear-sky conditions.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
