1. A photovoltaic (PV) module mounting system comprising:
- a mounting bracket having a first portion arranged to face a roof and a second portion arranged to face a PV array, wherein the first and second portions are spaced apart from one another and have a curved cross-sectional shape;
a pair of flat mounting feet portions on the first portion;
a first slot formed in the first portion and a second slot formed in the second portion, wherein the first slot and second slot are aligned and the second slot is larger than the first slot;
a hanger bolt comprising a first threaded portion adapted to engage a roof surface, a second threaded portion adapted to pass through the first and second slots of the mounting bracket, and a washer located between the first threaded portion and the second threaded portion for limiting a depth that the first threaded portion can achieve in the roof surface;
a threaded knob adapted to mate with the second threaded portion of the hanger bolt and to compress the mounting bracket against a roof surface when rotational torque is applied to the threaded knob; and
a PV module coupling device attached to the mounting bracket and adapted to engage frames of and maintain a space between at least two photovoltaic modules.

Abstract
A photovoltaic (PV) module mounting system including a mounting bracket that has a curved mating surface extending as an arch between a pair of flat mounting feet portions. The mounting bracket supports a PV module coupling device. A hanger bolt is provided that has a first threaded portion adapted to engage a roof surface and a second threaded portion for passing through the curved mating surface of the mounting bracket. A threaded knob is adapted to mate with the second threaded portion of the hanger bolt.

16. A photovoltaic (PV) module mounting system comprising:
-
a mounting bracket comprising an elongated and curved mating surface, the mounting bracket configured to hold a PV module coupling device; a hanger bolt adapted at a first threaded end to engage a roof surface; and a threaded knob adapted to mate with a second threaded end of the hanger bolt while pressing against the mating surface, wherein the curved mating surface is shaped to compensate for angular misalignment of the hanger bolt with respect to the mounting bracket, wherein the mounting bracket comprises a first arch that defines the mating surface, wherein the mounting bracket comprises a second arch disposed above the first arch. - View Dependent Claims (17, 18, 19, 20)
