Mechanical panel interface

A method, comprising:

• forming a base member as a bottom of a module frame, wherein the base member defines a horizontal axis;
• forming at least one support member of the module frame extending vertically away from the horizontal axis defined by the base member;
• forming a module receiving void of the module frame, wherein the module receiving void is configured to receive an edge of a PV module, wherein the module receiving void is located above the at least one support member, and has an opening on a same side of the PV module frame as the at least one support member;
• forming a bracket interface of the module frame, wherein the bracket interface has an opening located on an opposite side of the module frame than the module receiving void, and wherein the bracket interface is configured to receive, within a perimeter of the module frame, a tab of a corresponding module bracket;
• and
• forming at least one enclosed area of the module frame located above or below the bracket interface.
