Astra v.2.200 <br />4/28/2026 02:11 AM CAT 1, EOSS <br />#AStamp <br />Subject: Structural Certification for Proposed Residential Solar Installation. <br />Job Number: 109R-306POBO2; Rev A <br />Client: JAMES POBOG <br />Address: 2306 W Manly Ave, Santa Ana, CA 92704 <br />Attn: To Whom It May Concern Signed on: 4/28/2026 <br />A Sunrun representative has gathered site information on this structure in preparation for this permit application. A structural load evaluation <br />has been completed which compares the loads before and after the panel installation. For this structure, the calculated maximum roof load <br />after PV panel installation is less than the gravity and lateral load analysis triggers as set forth in the IEBC. <br />Based on an exterior inspection, this structure is performing adequately under the current loading. Prior to installation of the solar PV system, <br />a Sunrun representative will confirm that the attic roof framing has no unsafe or dangerous conditions present. Any localized items requiring <br />repair will be addressed as a part of the installation by the installing contractor and prior to installation. <br />Structural evaluation of the loading is based on the applicable design criteria listed below. <br />Design Criteria: <br /> • 2025 CBC/CEBC, 7-22 ASCE & 2024 NDS <br /> • Basic (Category II) Wind Speed V=95 mph, Exposure B <br /> • Ground Snow Load = 3 psf <br />Based on this evaluation, I certify that the alteration to the existing structure by installation of the PV system meets the requirements of the <br />applicable existing building code provisions adopted/referenced above. Additionally, the PV module assembly and hardware supporting it have <br />been designed according to manufacturer's specifications per the loading criteria referenced above. <br />Installer shall inspect the existing roof framing to verify it is in suitable condition and does not exhibit signs of damage which may diminish the <br />capacity of its members or connections. If damage exists, the installer shall notify the engineer of record prior for guidance to proceeding with <br />installation. <br />Results Summary (Hardware Check Includes Uplift Check on Attachments/Fastener, Structure Check Considers Main Structure) <br />AR-01 <br />Orientation Attachment Spacing/Cantilever Configuration Max DCR Result <br />Landscape 58 / 6 Staggered 36%Pass <br />Portrait 58 / 6 Staggered 31%Pass <br />Roofing Material Pitch Structure Check <br />Comp Shingle 18°Pass <br />AR-02 <br />Orientation Attachment Spacing/Cantilever Configuration Max DCR Result <br />Landscape 58 / 6 Staggered 36%Pass <br />Portrait 58 / 6 Staggered 31%Pass <br />Roofing Material Pitch Structure Check <br />Comp Shingle 18°Pass <br />225 Bush St. Suite 1400 San Francisco, CA 94104 <br />Exp. 12/31/2026 <br />Digitally Signed On: 04/28/2026
