The SolarPlots API provides a new data tool to track where the sun will be in any given location in the US (and adjacent parts of Mexico and Canada) for any specific date and time or series of dates. The sun plotting search tool could possibly be used by photographers needing to know best times to shoot twilight scenes, for sun-bathers wanting to book the best time on a hotel rooftop, or home buyers wanting to calculate how much direct sunlight their new property may get. Developers could use the app to scale up such individual needs or to add sun-loving contextual information to a location-based app product.
