<br />Note to Building Official:
<br />Based upon a review of the proposed plans and information, the
<br />existing roof framing system is capable of safely supporting the additional
<br />loads caused by the new solar photovoltaic energy system. The contractor
<br />shall field verify that the existing roof structure is in its original permited
<br />condition and verify that it can support the normal code required roof live
<br />loads. Attached in this package are several calculations showing that the roof
<br />members can support the additional weight of the solar array.
<br />Furthermore, an analysis of the solar array's support for wind forces and a
<br />seismic analysis of the existing structure are also included.
<br />W DL + LL
<br />R1 R211'
<br />Total load on rafter = 40 plf x 11 ft. = 440 lbs
<br />Check Existing 2x12 Roof Rafters @ 16" O.C.: *
