Mounting apparatus to secure solar panel rails to stone-coated metal tile roofs

A mounting apparatus to secure a pair of solar panel rails to a metal tile roof and minimize penetrations or damage to a rafter of the roof positioned below a plurality of metal tiles, the mounting apparatus configured to permit the pair of solar panel rails to support a pair of adjacent solar panels thereon, the mounting apparatus comprising:

• a lower assembly coupled to the metal tile roof and comprising a threaded screw, a flashing, and a post member, the threaded screw disposed through the rafter and extending through one of the metal tiles to a position above the roof, the flashing comprising a plate disposed on the one of the metal tiles and comprising a central opening to permit the threaded screw to extend therethrough, the flashing comprising a flange coupled to the central opening of the plate, the post member disposed on the flashing and positioned entirely above all portions of a top surface of the flashing, the post member comprising a partially hollow cylindrical member with an interior central tubular member extending through the cylindrical member, the partially hollow cylindrical member comprising interior space within the cylindrical member that surrounds the interior central tubular member and extends from a top end of the post member to a bottom end of the post member, the interior central tubular member of the post member configured to permit the threaded screw to pass therethrough, wherein the lower assembly comprises a first washer disposed around the threaded screw and in contact with the flashing and the post member, a cap disposed around the threaded screw and disposed around the top of the post member, and a second washer disposed around the threaded screw and coupled to the cap;
• and
• an upper arm assembly coupled to the threaded screw of the lower assembly by fasteners, the upper arm assembly comprising a generally U-shaped member with a central opening that receives the threaded screw therethrough, the fasteners comprising a first nut disposed around the threaded screw and coupled to a bottom portion of the U-shaped member and a second nut disposed around the threaded screw and coupled to a top portion of the U-shaped member, the U-shaped member comprising a first symmetric half portion and a second symmetric half portion, each symmetric half portion of the first and second symmetric half portions comprising a slot configured to receive a fastener that secures one of the pair of solar panel rails thereto, thereby permitting the mounting apparatus to support the pair of solar panel rails above the metal tile roof.
