The present invention is directed to an apparatus for stacking a plurality of solar module arrays each having a plurality of solar panels. The apparatus includes a lower portion disposed on top of a first solar panel support channel corresponding to a first solar module array, and an upper portion for supporting a second solar panel support channel corresponding to a second solar module array, wherein the second solar module array is stacked above the first solar module array.

The invention relates to a profile rail, a clip holder, a cross-connector and an attachment system for mounting solar modules. The components are so designed and matched to each other that solar modules in many variations can be mounted quickly and easily and with the components having a low weight.

Mounting clamps may be utilized to quickly and easily secure solar panel modules relative to mounting rails, which may in turn be secured relative to a mounting surface (e.g., a roof). The mounting clamps may be configured to quickly secure the solar pane modules relative to the mounting rails by tightening a tightening element to pull a clamp element toward the surface of a mounting rail, thereby clamping a portion (e.g., a frame) of a solar panel module between the clamping element and an outer surface of the mounting rail.

Roof panels with an integrated solar energy unit secured in a perimeter frame are disclosed. Pressure equalized airloops are provided around the perimeter frame to prevent water leakage. The solar energy units in adjacent roof panels are electrically connected by wires penetrating the head frame member of each roof panel and passing through a supporting mullion between the adjacent panels.

An airloop curtain wall system with solar energy units integrated into the curtain wall panels is disclosed. The disclosed system provides electrical connections between adjacent solar energy curtain wall panels without compromising the curtain wall watertightness performance and permits easy replacement of solar energy units from the building interior.

Discussed are solar panel systems as well as devices and methods for mounting the solar panel systems to roofs and building structures. Catch clamp, mid clamp, and optionally end clamp assemblies can be preinstalled to the solar panels at the job site before placing and securing the resulting solar panel assemblies to the building structure such as a roof. After an installer places and secures a first solar panel assembly to the building structure, they can install each subsequent solar panel assemblies by attaching the leading edge of the subsequent solar panel assembly to the trailing edge of the previous solar panel assembly using a catch and catch receiver, hook and slot, tab and slot, or similar mechanism.
