Precision-Modular integrates wire-management and features rubber feet that prevent metal from touching the roof, often eliminating the need for slip sheets. Feet also stack to easily deal with roof undulations. The system is connected north/south and east/west to better distribute loads, and doesn’t rely on the module frame as a structural element. The building block design is assembled, laid out and installed module-by-module to maximize layout flexibility, dramatically reduce costs through inventory, and facilitate on-roof changes. Available for 60 and 72-cell modules and 10 degree tilt.
