Photovoltaic module support system and mount assembly

A mounting assembly comprising:

• a rail configured to at least partially support a photovoltaic module, the rail including:
• a first slot formed in a first side of the rail,
• a second slot formed in a second side of the rail, and
• a web extending between the first slot and the second slot, the web being offset from a plane extending along an outer surface of the rail, so as to form a recess in the second side of the rail;
• and
• a clip configured to be secured to the rail and to a secondary structure, the clip including:
• a base having:
• a first flange extending from a first end of the base in a first direction, the first flange being inserted in the second slot when the clip is secured to the rail and the secondary structure, and
• a second flange extending from a second end of the base in the first direction, and the second flange spaces the base of the clip from the secondary structure when the clip is secured to the secondary structure, and
• an arm extending from the base in a second direction opposite the first direction, at least a portion of the arm abutting the recess of the rail when the clip is secured to the rail.
