Zep System I offers the fastest and least expensive way to install PV arrays for flush-mount tile roof applications. With its ability to optimize attachment point spacing in both east-west and north-south axes, Zep System I can offer a 25% reduction in roof attachment points dramatically reducing the amount of time spent on the roof. With a series of drop-in, rock-in, and quarter-turn connections, Zep System I in-stalls without the use of lengthy rails and separate grounding hardware and is universally adaptable to third-party roof attachment solutions such as tile-hooks, hanger bolts, and flashed standoffs.
