Built-In Solar Mounting Rails — Not Solar Panels Used as Roof Tiles

Does “photovoltaic integrated roofing” mean the roof is made of solar panels? Not in this case.

The system described here uses roofing with built-in mounting rails. Solar panels are installed onto those rails separately—the roofing itself is not a solar panel.

How Does It Work?

A conventional rooftop solar installation typically requires separate mounting components, such as clamps and rails, to secure the panels.

With this system, the mounting rails are already built into the roofing. Installers secure the solar panels using concealed bolts, nut blocks, and module clamps, rather than adding a separate rail system.

What Are the Main Benefits?

No drilling through the roofing to attach the panels, helping preserve the roof’s waterproofing.
Fewer separate mounting components, which can reduce material use and installation costs.
A simpler installation process, helping crews work more efficiently on site.
