Stage materials and layout so modules aren’t transported over the partially-built array. Prior to beginning installation, verify that there are no roof obstructions within the array perimeter.

Use a chalkline to draw the array outline using the following guidelines:

1A. Mark the module dimension + 1/2 inch.

1B. Mark the maximum span (multiple of distance between metal roof seams).

1C. Then, identify and mark the attachment locations (Seam Mounts) according to the project plan set.
