Loyd W. Martin Solar Structures Engineering <br />2510 W. 237th St. #206 Torrance, CA 90505 Tel:1.310.464.1804 <br />Email: loydwmartin@gmail.com www.loydwmartin.com <br />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 Roof Rafters: <br />W DL + LL - <br />r/////////////////////////////A <br />w = 30 psfx 2 ft. = 60 pif 2 <br />t Rl R2 <br />19.5' <br />Total load on rafter = 60 pif x 19.5 ft. = 1,170 lbs <br />i / CD .A\\ <br />M No. C58724.58 <br />* Exp. 3-31-15 * <br />d> C/V\L#rE OF C AL\F O- <br />2014- 755 Nexus Energy Sylvina Cornejo Residence <br />Sht # 2 of 6 <br />Date: May 16, 2014 <br />C
