4. Westinghouse Solar Mounting and Structural Requirements
To satisfy Westinghouse Solar's minimal structural requirements there are two simple design rules
that usually dictate the minimum mounting requirements. As Westinghouse Solar AC panels are
connected together they form a rigid structure. The span of the panels between roof attachments
is generally 48”. As per the Technical Engineering Report (available on WestinghouseSolar.com,
greater spans can be used in sheltered wind condition areas, and shorter spans may be necessary
under high wind conditions. These roof attachments are located on both the top and bottom of
your single row array. The second rule requires that panels which overhang the last footing in a
row may stick out no more than a maximum of 16" from that footing.
Before finalizing your roof
drawing, check with your local building department to identify any unique wind or snow load
requirements that pertain to your jurisdiction. A combination of shortening the maximum span
between roof attachments and increasing the length of your lags will enhance the wind load
rating of Westinghouse Solar AC panels. Refer to the
Technical Engineering Report on
www.westinghousesolar.com to determine maximum allowable anchor spacing.
