A mounting system for solar panels that is adjustable to allow for ease of installation. An adjustable leg or strut includes a telescoping portion that is connected to a base by a compound ball joint. At an upper end, an angularly adjustable bracket allows for connection to a rail for supporting the solar panel. In a typical installation, two series of adjustable legs are used to support two rails at differing heights to support a panel in a desired position. The adjustable nature of the components allows for a faster installation compared to known solar panel mounting systems.
