We have reviewed the solar panel installation site plan and conclude that the panels will not negatively affect the structure at the site mentioned above. The solar panels and their respective design, attachments, and connections shall be per the responsibility of the manufacturer/installer and shall be installed and designed in accordance with the 2018 IBC and ASCE 7-16. The structure is adequate to take on the additional lateral loads due to the solar panels for the following reasons: Any increase in wind loads is negligible due to the mounting pattern of the panels being flush with the existing roof. The solar panels weigh 2.5 psf. Per the IEBC section 503.4, the lateral force resisting system need not be adjusted for less than a 10% change in seismic loads. Since the roof dead load is 15 psf, and the solar panels that weigh 2.5 psf affect less than 50% of the roof structure, the increase in seismic lateral loads is less than 9%. The structure is also adequate to resist the gravity loads due to the solar panels for the following reasons: The live loads will be reduced in the areas where the solar panels are added because no roof live loads will be presen t and snow loads will be reduced. Snow loads will be reduced due to the slippery surface of the solar panels and the heat produced by the black surface. The snow will be more likely to melt and slide off of the panels and be reduced due to these elements as per ASCE 7-16 Figure 7.4-1. With these reductions in the live loads, we can conclude that the additional 2.5 psf increase in dead load will be adequately offset by the reductions in the governing live load. All attachments of the solar panels to the roof structure shall be staggered and spaced on various rafters/truss top chords per the rail system manufacturer in order to have the loads shared by multiple roof structural elements. Focus Engineering & Surveying is not responsible for any problems produced due to improper installation. Focus Engineering & Surveying also assumes the structure is in good condition and was adequately designed by the original design professional and assumes no liability for problems existing due to improper original design.

Sincerely, Lynn Gray Focus Engineering & Surveying Reviewed By: Matthew S. Hakes, P.E. Project Engineer Focus Engineering & Surveying Design Criteria & Assumptions: Ground Snow Load – 45 psf Roof Snow Load – 35 psf We have been retained to review the feasibility of adding solar panels to the above referenced site. We have reviewed the solar panel installation site plan and conclude that the panels will not negatively affect the structure at the site mentioned above. The solar panels and their respective design, attachments, and connections shall be per the responsibility of the manufacturer/installer and shall be installed and design ed in accordance with the 2018 IBC and ASCE 7-16. The roof structure is composed of 2x4 prefabricated trusses @ 24” o.c and appears to be in adequate condition. The structure is adequate to take on the additional lateral loads due to the solar panels for the following reasons: Any increase in wind loads is negligible due to the mounting pattern of the panels being flush with the existing roof. The solar panels weigh 2.5 psf. Per the IEBC section 503.4, the lateral force resisting system need not be adjusted for less than a 10% change in seismic loads. Since the roof dead load is 15 psf, and the solar panels that weigh 2.5 psf affect less than 50% of the roof structure, the increase in seismic lateral loads is less than 10%. The structure is also adequate to resist the gravity loads due to the solar panels for the following reasons: Per the IEBC section 503.3, the gravity force system need not be adjusted for less than 5% change in gravity loads. Since the roof snow load is no less than 35 psf, the roof dead load is 15 psf, and the solar panel load is 2.5 psf, the 5% load increase threshold is not reached in any added panel areas and therefore the pre-fabricated metal plated trusses are adequate to resist the additional load of the solar panels. All attachments of the solar panels to the roof structure shall be staggered and spaced on various rafters/truss top chords per the rail system manufacturer in order to have the loads shared by multiple roof structural elements.
