Pw-R HR Field-Assembled, Rail-Less System

The Pw-R HR Field-Assembled, Rail-Less System is a photovoltaic mounting system from All Weather Insulated Panels. It is part of the Pw-R solar series and is marked as featured in the manufacturer's solar listing.

The assembly attaches directly to the high rib of the roof panel. No rails are used, which separates it from the rail-based systems in the same series.

EPDM rubber backing is pre-applied to the clamp components. The weather-resistant design uses this backing for ease of installation.

The components are designed for easy shipment and efficient transportation.

Production of the manufacturer's foam composite insulated metal panels runs on continuous lines at three plants, in Vacaville, California, Little Rock, Arkansas and East Stroudsburg, Pennsylvania. Pw-R products connect the panels to solar PV systems.

Roof panels with high SR and SRI values lower surface temperatures. Cooler panels raise PV efficiency and improve rear-side illumination for bifacial systems. Enhanced thermal insulation reduces heat transfer through the roof assembly.

Of the three systems in the Solar category, the rail-less HR system is the one that mounts straight to the high rib.

The series also includes the Pw-R HR Field-Assembled Rail-Based System, which is compatible with all roof slopes, and the Pw-R SR2 Field-Assembled Rail-Based System. OneDek, the deck-through-membrane roof deck with a 20-year weathertightness warranty available, is shown as a related product. The rail-less system mounts to the rib of insulated metal panels for roofs and walls.
