5. Drafting a Solar Array
Begin drawing Westinghouse Solar panels on the predetermined solar roofs considering the above
mentioned design parameters. Westinghouse Solar AC panels measure 65.3" long by 39.3” wide.
Include a 1" gap between rows in the north/ south direction to accommodate the installation of the
Westinghouse Solar North-South Bracket. To allow for thermal expansion in large arrays, include a
one inch expansion gap for every 12 Westinghouse Solar panels in a continuous row.
Take time to review how the Westinghouse Solar components you are working with are
developed and organized in the included roof layout. The default roof attachment profiles
included in the Appendices may be attached to your plans for review by local planning and
permitting jurisdictions.

Adding Additional Equipment to the Roof Layout
Westinghouse Solar AC Wire Runs
After the roof layout is complete with Westinghouse Solar AC panel locations and the existing
electrical service, identify where conduit or Romex will be run to route the arrays conductors to
the associated equipment on the ground. This can be done by simply drawing a line across your
site map and labeling the material as is seen in the sample roof layout.
Conductors
Conductors will either be run as Romex internally or through an approved conduit externally. If
an external disconnect is required in your jurisdiction, include this location on the roof layout.
Label all equipment and conduit sizes on the roof layout.
