Support apparatus for supporting a plurality of solar energy collection devices

Apparatus for supporting a plurality of solar energy collection devices 901 on a roof comprising a plurality of rails 901, a plurality of elongate wind deflector elements 910, and a plurality of securing devices. In the support matrix, the rails are spaced apart and extend substantially in a first direction, the elongate wind deflector elements are spaced apart and extend substantially in a second direction, across the rails, and elongate wind deflector elements are connected to rails by securing devices located at intersections. The securing device may comprise a base element wherein the base element is preferably located within a slot in the rail. Brackets 905, 906 may be used to connect solar energy collection devices to the support matrix. An apparatus for collecting solar energy and a method of supporting solar energy collection devices on a roof are also claimed.
