Railless mounting system and devices for attaching solar modules to roofs

Abstract

Devices, systems, and methods for attaching solar modules to roofs. The devices may include a module hook clamp with a clamp body with clamp body arms extending upward from a clamp body base. The clamp body arms may include downward-facing hooks that engage a portion of the solar module's return flange and the outward-facing surface of the solar module. A spacer may optionally be positioned between the clamp body arms. The spacer may seat the solar module. A hook arm with a generally curve-shaped seating surface may extend below the clamp body base. The devices may further include a module attachment bracket that secures a second solar module in a similar manner as the module hook clamp. The module attachment bracket may include a platform that seats the hook arm of the module hook clamp, and a hook arm receiver that receives and secures the open end of the hook arm.
