Abstract

A bracket is disclosed for attaching solar panels to roof structures. The bracket may comprise first, second and third planar portions, the first and third portions generally parallel to each other, and the second planar portion disposed at an oblique angle with respect to first and third portions. The first portion may have a plurality of elongated stiffening members disposed at oblique angles with respect to a longitudinal axis of the bracket. Gussets may be provided across the transition between the first and second portions, and the transition between the second and third portions. The gussets and stiffening members are shaped, sized and oriented to enhance the strength of the bracket. The bracket may have a drain hole to allow water to pass through the bracket, and a plurality of fastener holes are provided to enable the bracket to attach to a variety of different solar panels and roof structures.
