The proposed installation will be 6" max. above the roof surface (flush mounted) and parallel to the roof surface. <br /> Therefore, any increase in wind loading on the building structure from the solar panel installation is expected to be <br /> negligible. Wind is the governing lateral load case. Because the increase in lateral loading is not increased by more <br /> than 10%, per section 806.3 of the adopted IEBC,the structure need not be altered for lateral loading. <br /> Wind uplift on the panels has been calculated in accordance with the relevant provisions of ASCE 7-16.This loading <br /> has been used to verify the adequacy of the connection specified above. Connection locations should be in <br /> accordance with design drawings. <br /> Conclusion <br /> When the retrofits detailed in this letter's opening paragraph are performed, the structure will have adequate <br /> strength to support the proposed installation. Connections to the roof must be made per the "Roof Connection <br /> Details" section above. Copies of all relevant calculations are enclosed. <br /> Limitations and Disclaimers <br /> The opinion expressed in this letter is made in reliance on the following assumptions: the existing structure is in <br /> good condition (apart from the damage which shall be repaired or retrofit per the above); the existing structure is <br /> free from defects in design or workmanship; and the existing structure was code-compliant at the time of its design <br /> and construction.These assumptions have not been independently verified, and we have relied on representations <br /> made by the property owner and his or her agents with respect to the foregoing. The undersigned has not <br /> Electrical engineering is beyond the scope of this analysis. Solar panels must be installed per manufacturer <br /> specifications. Structural design and analysis of the adequacy of solar panels, racks, mounts, rails, and other <br /> components is performed by each component's respective manufacturer and the undersigned makes no statement <br /> of opinion regarding such components.
