Note to Building Official: <br />Based upon a review of the proposed plans I am confident that 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 <br />roof 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 />Check Existing 2X10 Roof Rafters @ 36" O.C.: <br />(Assume max rafter span = 5 ft.) <br />w =30 psf x 3 ft. = 90 plf <br />Total load on rafters = 90 plf x 5 ft. = 450 lbs <br />Sht # 2 of 7 <br />2023-4620 Effect Energy George Hansen August 24, 2023 <br />      Loyd W.
