Multiple Module Rows
After defining the corners of the array on the roof using chalk or a wax crayon, snap chalk lines
representing rows of attachment points required for your array. In the following sample array
there are three rows of attachment points to accommodate two rows of Westinghouse Solar
modules. The first row of attachment points starts at the bottom horizontal perimeter of the
Array. Snap a chalk line across the bottom two corners of the array to define the first row of
attachment points. The second row of attachment points is created by measuring 65-5/8" up
the pitch of the roof from the first chalk line; snap a second line at this interval. The spacing
interval for the next row of attachment points up the pitch of the roof is 66-1/2". This larger
distance represents the necessary three quarter inch gap between all rows in the north/ south
direction. If a third row of modules were to be installed there would also be 66-1/2" space
between the third and fourth row of attachment points. Note that all L-Brackets are oriented in
the same direction; this allows access to secure the Lag bolts once modules are put in place. The
measurements in the Figure above represents distance between lag bolt penetrations;
Westinghouse Solar L-brackets feature an adjustable oblong base slot that is adjusted to exact
module dimensions as the system is installed.
