A module rail for a photovoltaic system includes a module-supporting surface extending along the length of the module rail for supporting at least one photovoltaic module thereon. A vertical sidewall extends downward from a side of the module-supporting surface. Fastener openings are spaced apart from one another along the length of the rail. Each of the fastener openings extend through the sidewall generally adjacent to a juncture of the module-supporting surface and the sidewall. Each of the fastener openings is configured to receive a clip fastener for securing a photovoltaic module on the module-supporting surface.
