Polar - Model PRG - Grid-Based Ballasted Flat Roof System - Brochure

Our grid-based modular racking solution, maximizes load sharing within each interconnected solar array, which reduces the number of ballast stones and the number of locations that stones are required. The lightweight, self spacing, interconnect design also works very well on anchored, or hybrid (ballast + anchor) systems, where you will require far fewer anchors on a PRG system than with other systems. Our system is designed to distribute loads evenly, thereby minimizing point loading. The PRG is ideal for flat roofs of all types.
