Note to Building Official:
Based upon a review of the proposed plans I am confident that the
existing roof framing system is capable of safely supporting the additional
loads caused by the solar photovoltaic energy system. The contractor
shall field verify that the existing roof structure is in its original permitted
condition and verify that it can support the normal code required roof live
loads. Attached in this package are several calculations showing that the
roof members can support the additional weight of the solar array.
Furthermore, an analysis of the solar array's support for wind forces and a
seismic analysis of the existing structure are also included.
