Rail-less solar panel devices and system for roofs and the like and methods for mounting same

A system for securing solar panels to a building structure, comprising:

• a first solar panel, the first solar panel includes a first solar panel frame, the first solar panel frame surrounds the first solar panel;
• a second solar panel, the second solar panel includes a second solar panel frame, the second solar panel frame surrounds the second solar panel;
• a catch clamp that includes a first solar panel bottom clamp and includes a first clamp jaw and a hook arm, the first clamp jaw removably clamps the catch clamp directly to a leading edge of the second solar panel frame, the hook arm includes a downward-facing generally convex shape with an open end that extends upward beyond the leading edge of the second solar panel frame toward a trailing edge of the first solar panel frame;
• a solar panel clamp assembly that includes a second solar panel bottom clamp and is removably clamped directly to the trailing edge of the first solar panel frame, the solar panel clamp assembly includes a panel hook platform and a hook receiver positioned above the panel hook platform with an end portion extending downward toward the panel hook platform;
• and
• the panel hook platform and the hook receiver are arranged and the hook receiver is so shaped, that the hook arm is pivotable against the panel hook platform as the open end of the hook arm engages the hook receiver and pivotally secures the second solar panel to the first solar panel.
