Summary of Existing Structure Results Roof - Adaquate to support the additional imposed loads. No structural upgrades are required. The following structural design regarding the proposed alterations have been prepared from these assumptions. The verification of the field observations is the responsibility of the contractor. Prior to commencement of work, the contractor shall verify the framing sizes, spacings, and spans noted in the sealed plans, calculations, and/or certification letter and notify the Engineer of Record of any discrepancies. After review of the field observations and based on our calculations and in accordance with the applicable building codes and current industry standards, the existing roof structure supporting the proposed alterations consisting of the solar array has been determined to be: Lucent Engineering, P.C. July 17, 2023 We have reviewed the following information regarding the solar panel installation for this project. Alterations to these documents or plans shall not be made without direct written consent of the Engineer of Record. D. Solar Panel Support Bracket Anchorage 1. 2.

E. Overall Summary Sincerely, Michael Leeper, PE License No. 56187 Limits of Scope of Work and Liablity Page 2 of 2 Hutchinson Residence The existing structure is assumed to have been designed and constructed following appropriate codes at the time of erection and assumed to have appropriated permits. The calculations performed are only for the roof framing supporting the solar array installation referenced in the stamped plans and were completed according to generally recognized structural analysis standards and procedures, professional engineering, and design experience opinions and judgements. Existing deficiencies which are unknown or were not observed during the time the site observation are not included in this scope of work. All solar panel modules, racking, and mounting equipment shall be designed and installed per the manufacturer's approved installation specifications. The Engineer of Record and the engineering consulting firm assume no responsibility for misuse or improper installation. This analysis is not stamped for water leakage. Framing was determined on information in provided plans and/or photos, along with engineering judgement. Prior to commencement of work, the contractor shall verify the framing sizes, spacings, and spans noted in the stamped plans, calculations, and/or certification letter and notify the Engineer of Record of any discrepancies prior to starting construction. If during solar panel installation, the roof framing members appear unstable or deflect non-uniformly, our office should be notified before proceeding with the installation. The contactor shall also verify that there are no damage/deficiencies (i.e., dry rot, water damage, termite damage, framing member/connection damage, etc.) to framing that was not addressed in the stamped plans, calculations, and/or certification letter and notify the Engineer of Record of any concerns prior to starting construction. Lucent Engineering, P.C.July 17, 2023 Should you have any questions regarding this letter or if you require further information, do not hesitate to contact me. Considering the existing roof's slope, size, spacing, condition, and calculated loads, the panel bracket supports shall be placed no greater than 48 in. o/c. Panel supports connections shall be staggered to distribute load to adjacent trusses. Solar panels shall be designed, mounted, and installed in accordance with the most recent ''Ironridge Manual'', which can be found on the Ironridge website (http://ironridge.com). Based on the information supplied to us at the time of this report, on the evaluation of the existing structure, and solar array panel bracket connection, it is our opinion that the roof system will adequately support the additional loads imposed by the solar array. This evaluation conforms to 2020 MNRC and current industry standards. 07/17/2023 DRAWN BY: SoloCAD 7/14/2023 DAKOTA ELECTRIC UTILITY ACCOUNT HOLDER: RICHARD HUTCHINSON SITE INFORMATION RICHARD HUTCHINSON 5613 UPPER 179TH STREET WEST LAKEVILLE, MN 55044 AC SYSTEM SIZE: 7.68 KW AC DC SYSTEM SIZE: 8.855 KW DC LAT, 44.6892332 LONG, -93.1787896 (23) JINKO SOLAR EAGLE 66TR G4 JKM385M-6RL3-B PV MODULES (12) AP SYSTEMS DS3-S INVERTER(S) Everlight Solar Construction 7369 Highway 13 W.
