Abstract

A module mounting system may include a photovoltaic (PV) module frame including a mounting rail. The module mounting system may include a spring clip with a PV module frame interfacing element and a clip interfacing element. The spring clip may apply spring force via deformation to lock the PV module frame and a clip together. A second embodiment of the spring clip may include an upper component having one or more arms and a lower component having a central loop configured to rotate relative to each other and interface with the PV module frame or the mounting rail. A second embodiment of the module mounting system may include screwless clips including outer walls and inner walls coupled together as a continuous sheet of material. The screwless clips may couple to a respective mounting flange and a respective frame flange to lock the mounting purlin and the PV module frame together.

First claim

What is claimed is:

1. A module mounting system, comprising:
a mounting rail shaped to interface with a photovoltaic (PV) module frame, the mounting rail including a locking portion comprising a lock ramp disposed along a bottom surface of the mounting rail;
one or more support structures to which the mounting rail is coupled; and
a mounting clip with a PV module frame interfacing portion and a mounting rail interfacing portion, the mounting clip shaped to apply force via deformation of the mounting clip to force the mounting rail and the PV module frame against each other and wherein the mounting rail interfacing portion is configured to engage with the locking portion, wherein the mounting rail interfacing portion comprises a central loop configured to slide over and engage with the lock ramp.

2. The module mounting system of claim 1 , wherein the mounting rail is shaped to further interface with a second PV module frame, wherein:
the PV module frame that the mounting rail is shaped to interface with includes a first flange that extends in a first direction and interfaces with a top surface of the mounting rail;
the second PV module frame includes a second flange that extends in a second direction and interfaces with the top surface of the mounting rail; and
the PV module frame interfacing portion of the mounting clip includes at least a first and a second wing, the first wing configured to slide over the first flange and the second wing configured to slide over the second flange such that the first wing interfaces with a top surface of the first flange and the second wing interfaces with a top surface of the second flange.

3. The module mounting system of claim 1 , wherein the lock ramp includes a profile that facilitates sliding the central loop over the lock ramp in a first direction and prevents sliding the central loop over the lock ramp in a second direction.

4. A module mounting system, comprising:
a mounting rail shaped to interface with a first flange of a first photovoltaic (PV) module frame and a second flange of a second PV module frame; and
a mounting clip with a PV module frame interfacing portion and a mounting rail interfacing portion, the mounting clip shaped to force the mounting rail and the PV module frame against each other;
wherein the PV module frame interfacing portion includes a first wing portion configured to engage a top surface of the first flange and a second wing portion configured to engage a top surface of the second flange.

5. The module mounting system of claim 4 , wherein the mounting rail interfacing portion is configured to engage with a locking portion disposed on the mounting rail.

6. The module mounting system of claim 5 , wherein the locking portion comprises a lock ramp disposed along a surface of the mounting rail and the mounting rail interfacing portion includes a surface configured to slide over and engage with the lock ramp.

7. The module mounting system of claim 6 , wherein the lock ramp includes a profile that facilitates sliding the surface of the mounting rail interface portion over the lock ramp in a first direction and prevents sliding the surface over the lock ramp in a second direction.

8. A module mounting system, comprising:
a mounting rail shaped to interface with a first photovoltaic (PV) module frame and a second PV module frame, wherein:
the mounting rail comprises a locking portion;
the first PV module frame comprises a first flange that extends in a first direction and is configured to interface with a top surface of the mounting rail; and
the second PV module frame comprises a second flange that extends in a second direction and is configured to interface with the top surface of the mounting rail;

a support structure to which the mounting rail is coupled; and
a mounting clip comprising:
a PV module frame interfacing portion comprising;
a first wing configured to slide over the first flange to interface with a top surface of the first flange; and
a second wing configured to slide over the second flange to interface with a top surface of the second flange; and
a mounting rail interfacing portion configured to engage with the locking portion, wherein the mounting clip is shaped to apply a force via deformation of the mounting clip to force the mounting rail and the PV module frame against each other.
