Little Elm occupies a peninsula on the eastern shore of Lake Lewisville in Denton County, bordered by Frisco, The Colony, Aubrey, and Hackberry. Its growth has been extraordinary — from a small lakeside community of a few thousand to a city of 55,000+ with major master-planned developments that are still expanding. That growth means Little Elm has one of the newest housing stocks in DFW, which translates to excellent solar installation conditions: modern panels, updated electrical systems, and clean roof decks.
