Vreeland Design Associates Re: Ron Bushey, 40 Austin Circle, Florence, MA: Structural assessment of existing house roof to support proposed PV solar panel array. I have investigated the existing roof framing for the proposed PV solar panel installation. Based on the Assessor’s records the original 24’x 40’, 1-story ranch style house with a 1-story 20’x 20’ ell off the back of the house was constructed in 1970. 10 PV solar panels are to be installed on the front southeast facing roof of the house. The house roof is framed with 2x4 Fink design trusses installed 24” on-center, spanning 24’ with a 5/12 roof pitch. The roofing is composite asphalt shingles. I have reviewed the mounting details for the proposed PV solar panel array. Based on my calculations and on the specified PV solar panel unit weight of 48± lbs, with the attachment points of the solar panel array placed at a maximum of 4’ on center and staggered to minimize the load to any one roof truss, the existing house roof framing is adequate to support the proposed PV solar panels and the 40 psf ground snow load, the 35 psf roof snow load and the 117 mph Vult basic wind speed requirements of the current 9th Edition of the MA State Building Code for the City of Northampton. Please contact me if you have any questions or need additional information.

IQ8MA-12A-DS-0069-03-EN-US-2022-12-27 Tech Brief Solar Is Not Always Sunny Over their lifetime, solar panels experience countless extreme weather events. Not just the worst storms in years, but the worst storms in 40 years. High winds capable of ripping panels from a roof, and snowfalls weighing enough to buckle a panel frame. XR Rails are the structural backbone preventing these results. They resist uplift, protect against buckling and safely and efficiently transfer loads into the building structure. Their superior spanning capability requires fewer roof attachments, reducing the number of roof penetrations and the amount of installation time. XR Rail Family Force-Stabilizing Curve Sloped roofs generate both vertical and lateral forces on mounting rails which can cause them to bend and twist. The curved shape of XR Rails is specially designed to increase strength in both directions while resisting the twisting. This unique feature ensures greater security during extreme weather and a longer system lifetime. Compatible with Flat & Pitched Roofs Roof Mount utilizes XR Rails, along with optional all-in-one attachments, to secure systems flush against residential roofs. Corrosion-Resistant Materials XR Rails are compatible with FlashFoot and other pitched roof attachments. IronRidge offers a range of tilt leg options for flat roof mounting applications. All XR Rails are made of 6000-series aluminum alloy, then protected with an anodized finish. Anodizing prevents surface and structural corrosion, while also providing a more attractive appearance. XR Rail Family The XR Rail Family offers the strength of a curved rail in three targeted sizes. Each size supports specific design loads, while minimizing material costs. Depending on your location, there is an XR Rail to match. © 2020 IronRidge, Inc. All rights reserved. Visit www.ironridge.com or call 1-800-227-9523 for more information.
