Mounting apparatus to secure solar panel rails to S-tile roofs
View Patent ↗A mounting apparatus to secure a pair of solar panel rails to a S-tile roof and minimize penetrations or damage to the roof's rafter is provided. The mounting apparatus includes a lower hook assembly with a plate coupled to the roof's rafter and an upright tab coupled to the plate, and an upper arm assembly coupled to the lower hook assembly's upright tab, the upper arm assembly having a generally U-shaped member with a first symmetric half member and a second symmetric half member, each symmetric half member having a slot to receive a fastener that secures one of the pair of solar panel rails thereto. The upper arm assembly is slidably mounted to the upright tab of the lower hook assembly to permit height adjustments of the upper arm assembly relative to the S-tile roof. The apparatus can also be used with M, W and clay tile roofs.
1. A mounting apparatus to secure a pair of solar panel rails to a S-tile roof and minimize penetrations or damage to a rafter of the roof, 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 hook assembly comprising a plate coupled to the rafter of the S-tile roof and a generally upright tab coupled to the plate; and
an upper arm assembly coupled to the generally upright tab of the lower hook assembly, the upper arm assembly comprising a generally U-shaped member comprising a first symmetric half member and a second symmetric half member, each symmetric half member of the first and second symmetric half members 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 S-tile roof;
wherein the upper arm assembly is slidably mounted to the generally upright tab of the lower hook assembly to permit height adjustments of the upper arm assembly relative to the S-tile roof, wherein the upper arm assembly comprises a generally L-shaped bracket continuously connected to a bottom surface of the U-shaped member and an arm tab continuously connected to the generally L-shaped bracket, the arm tab slidably mounted to the upright tab of the lower hook assembly.
2. The mounting apparatus of claim 1 , further comprising a first elongated hole disposed in the arm tab of the upper arm assembly and a second elongated hole disposed in the generally upright tab of the lower hook assembly, wherein the first elongated hole is aligned with the second elongated hole.
3. The mounting apparatus of claim 2 , further comprising a bolt disposed through the first and second elongated holes and coupled to a nut to detachably couple the arm tab of the upper arm assembly to the generally upright tab of the lower hook assembly.
4. The mounting apparatus of claim 3 , further comprising a plurality of holes disposed in the plate of the lower hook assembly, each hole in the plurality of holes configured to receive a screw disposed therethrough to secure the lower hook assembly to the rafter of the S-tile roof.
5. The mounting apparatus of claim 4 , further comprising a plurality of grooves disposed on a portion of an inner surface and a portion of an outer surface of each symmetric half member in the first and second half members of the upper arm assembly.
6. The mounting apparatus of claim 5 , wherein the slot of each symmetric half member in the first and second half members is surrounded by the plurality of grooves.
7. The mounting apparatus of claim 6 , wherein the upper arm assembly and lower hook assembly are made from 304 stainless steel.
