Frames for photovoltaic modules and mounting features

A frame for a photovoltaic module, the frame comprising:

• a base portion comprising a bottom surface and an interior sidewall extending from the bottom surface, the interior sidewall defining an opening and a throat accessible via the opening, the opening and the throat extending along a length of the frame and being configured to receive a first mounting element therein;
• a first leg extending from a midpoint of the interior sidewall;
• a second leg extending from the base portion proximate to the interior sidewall;
• an outer lip extending from the interior sidewall, the outer lip comprising:
• a curved outer surface;
• and
• a vertically extending portion adjacent to the first leg;
• and
• a panel support portion comprising:
• a panel support surface extending between a top of the first leg and a top of the second leg;
• and
• a panel sidewall comprising:
• a first sidewall portion extending from the panel support surface and a side of the first leg;
• and
• a second sidewall portion extending vertically from the first sidewall portion to define a convex curved surface therebetween,
• wherein the panel support surface and the panel sidewall at least partially define a panel cavity configured to hold a solar panel therein,
• wherein the first sidewall portion extends from the panel support surface to define a first concave curved surface between the first sidewall portion and the panel support surface,
• wherein the first sidewall portion extends from the side of the first leg to define an obtuse angle with the first leg and to define a second concave curved surface between the first sidewall portion and the first leg,
• wherein the outer lip extends from the interior sidewall such that the curved outer surface extends from the bottom surface of the base portion proximate the opening to the vertically extending portion, and
• wherein the outer lip and the first leg at least partially define a cavity, the cavity being configured to receive a second mounting element therein.
