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

The Pw-R HR Field-Assembled, Rail-Based System is a photovoltaic mounting system from All Weather Insulated Panels. It is part of the Pw-R solar series and is assembled in the field on rails.

The design works on any roof pitch and is compatible with all roof slopes. The photovoltaic modules can be installed in portrait or horizontal orientation.

The weathertight design uses a clamp assembly with EPDM rubber backing, which forms a watertight seal. This is the weathertight design highlight on the product page.

The system offers resistance to high wind pressures. The page lists no pressure values.

All Weather Insulated Panels manufactures foam composite insulated metal panels on continuous lines in Vacaville, California, Little Rock, Arkansas and East Stroudsburg, Pennsylvania. The Pw-R series pairs the insulated panels with solar PV systems.

The Product Highlights cover energy generation, a weathertight design and insulation. Panels with high SR and SRI values lower surface temperatures, which the page ties to PV efficiency and bifacial rear-side illumination.

The product page carries six brochures and one sustainability document.

The Solar category lists three systems, and the HR rail-based system is the one compatible with all roof slopes.

The listing also includes the Pw-R HR Field-Assembled Rail-Less System, whose clamp components carry pre-applied EPDM rubber backing, and the Pw-R SR2 Field-Assembled Rail-Based System for high and low slope roofs. RD1 is the low-slope roof product shown as the companion to complete the roof assembly. The HR designation refers to the manufacturer's HR roof series of insulated metal panels for roofs and walls.
