Re: Application for a building permit to install photovoltaic panels on the roof at: 1010 PINE LN, ESTES PARK Dear Sir: This letter addresses your review comments, which are accurate and to the point. In fact some of the errors in the original plans are mainly due to the standard template used in the drawings and are corrected according to your comments and the engineering letter: 1- The rafters size is 2x10. This was corrected in sheets PV-3 and PV-4 2- The ground snow load is 65 psf and was corrected in sheet PV-1 3- The Minimum wind speed is 175 mph and was corrected in sheet PV-1 4- The spacing of the anchors is 2’ and was corrected in sheet PV-4 5- The Maximum allowed cantilever is 12”, for calculated loads on Unirac solarmount rails. All panels shown in PV-4 are located within this limit.

Re: Application for a building permit to install photovoltaic panels on the roof at: 1010 PINE LN, ESTES PARK Dear Sir: This letter is to certify that the roof structure of the reference building has been inspected and deemed to be adequate without reinforcement to support the additional load of the solar panels as installed in the revised plan. The Gable roof structure consists of 2x10 Rafters at 24” O.C. And 12 ft span. The existing roofing material consists of asphalt shingles. The structural study uses 2021 IRC and ASCE 7-16. The following criteria were used: - Ground Snow load: 65 psf (Altitude = 7530 ft) (Using linear interpolation) - Wind Speed = Vult = 175 mph Exposure: C - Solar system distributed weight: 3 psf design load. Calculations are presented to certify the integrity of the panel connections under the maximum wind uplift and live load conditions. The panel racking connections to the roof structure are made with 5/16” Lag bolts embedded 3/4” through the roof sheathing and 4” through the roof rafters at 4 ft intervals. They are adequate to support the maximum wind uplift load and the maximum live shear load. These Lag bolts have a pullout strength of > 750 lb which gives a pullout safety factor in excess of 1.5. The racking structure, “SolarMount HD” by Unirac, can support the maximum downward load of 197 lb/ft over a 24” maximum span. The maximum allowable cantilever length for such downward load is 12” . This configuration provides adequate structural integrity with a large safety margin. Sincerely, Riad Zakhem, P.E. 7/19/2024 Riad Zakhem Digitally signed by Riad Zakhem Date: 2024.07.19 13:36:39 +03'00' The calculations are based on 2' OC attachements, the revision letter uses 2' OC and page PV-4 uses 2' OC. Do not use 4' OC, use the lay out on page PV-4. REVIEWED BY SAFEBUILT 07/22/2024 2 | P a g e DESIGN WIND LOAD CALCULATION The Design wind load is calculated using method I from ASCE7-16. The equation for determining the Design wind load for components and cladding is: Pnet (psf) = Kzt.I.Pnet30 Pnet (psf) = Design Wind Load  = adjustment for height and exposure category Kst = Topographic factor at mean roof height = 1 in our case I = Importance factor = 1 in our case Using the following parameter: Design wind speed Vult = 175 mph Average roof height = 20 ft Exposure factor = C Roof pitch = 34 degrees Effective wind area = 21 sqft (area of a single panel because of spacing between panels) We obtain:   = 1.21 * Pnet30 = 45 psf (Down) * Pnet30 = -78 psf (Uplift) Pnet (Down force) = Pd = 54 psf Pnet (Uplift) = Pu = -94 psf 7/19/2024 REVIEWED BY SAFEBUILT 07/22/2024 3 | P a g e STRUCTURAL CALCULATIONS Ground Snow Load = Pg = 65 psf Roof Live Load (snow) = Ps = 0.7 Ce Ct Is Pg = .7 x 1 x 1.1 x 1 x 65 = 50 psf Dead Load = 3 psf = D Design wind load (down) = 54 psf = Pnet Design wind load (up) = -94 psf = Pnet (up) 1- Total Downward Design Load Pd : Case 1: Pd = D + PS = 3 + 54 = 57 psf Case 2: Pd = D + 0.6 x Pnet = 3 + 0.6 x 54 = 35.4 psf Case 3: Pd = D + 0.75 x PS + 0.75 x 0.6 x Pnet = 64.9 psf Case 3 gives us the maximum value for Pd = 64.9 psf 2- Total Upward Design Load Pu: Pu = 0.6 x D + 0.6 x Pnet (up) = 0.6 x 3 – 0.6 x 94 = -54.6 psf • Downward design load per linear foot on racking = 197 lb/ft We use 2 ft as our span, since our anchors should be located on a rafter (rafters are 2 ft apart). Unirac is designed to handle up to 220lb/ft for regular duty rails. (OK) • Cantilever allowable length for 197 lb/ft load is 12”. • Based on 2 ft L foot spacing we get maximum uplift of -673 lb per anchor. The anchor used is a 5/16 in lag bolt with a minimum pullout capability of 250 lb/in penetration. Since we are using 4 in depth with the pullout strength > 1000 lb per lag bolt, this gives us: factor of safety > 1.5 7/19/2024 REVIEWED BY SAFEBUILT 07/22/2024 VICINITY MAP SITE MAP (N.T.S) SIGNATURE WITH SEAL VINCENT ANTLE NEW GRID-INTERACTIVE PHOTOVOLTAIC SYSTEM DC SYSTEM SIZE (14.350KW) WIND FLOW MAP GENERAL NOTES SCOPE OF WORK 1.
