This certification covers the module clamp, rail analysis, and attachment Tile hook/L bracket components. All information, data, and analysis contained within are based on, and comply with, the following building codes and typical specifications: Building Codes: 1. Minimum Design Loads for Buildings and other Structures, ASCE 7-16 2. 2022 California Building Code, by California Building Standard Commision 3. 2022 California Residential Code, by California Building Standard Commision 4. 2021 International Building Code, by International Code Council, Inc. 5. 2015 Aluminum Design Manual, by The Aluminum Association 6. CPP Wind Tunnel report number 9790, dated February 16 2017. 7. SEAOC PV-2, 2017 8. 2018 NDS, by the American Wood Council 9. UL 2703 Testing report for PV solar panels. 10. AC428, Acceptance Criteria for Modular Framing Systems Used to Support Photovoltaic (PV) Panels, November 1, 2012 by ICC-ES Component and Cladding Roof Zones: The Components and Cladding Roof Zones shall be determined based on ASCE 7 Chapter 30, and CPP Wind Tunnel test number 9790, dated February 16 2017. Notes: 1) Racking system and panels shall be installed per manufacturer’s specifications. 2) Design assumptions are specified in the Inputs pages of attached span tables. 3) Attachment design is based on 5/16” Dia. Lag Screw with 2.5” Embedment into SPF#2 or equivalent per NDS. Designer shall be responsible for verifying project specific site conditions. 4) Wind speeds are LRFD values. 5) Attachment spacing(s) apply to seismic design category E or less. Page 1 of 2 Design Responsibility: These tables are intended to be used under the responsible charge of a registered design professional where required by the authority having jurisdiction. In all cases, these tables should be used under the direction of a design professional with sufficient structural engineering knowledge and experience to be able to: • Evaluate whether these tables are applicable to the project, and • Understand and determine the appropriate values for all input parameters of these tables. This letter certifies that the loading criteria and design basis for SunPower Universal Invisimount Mounting System Span Tables are in compliance with the Codes above. This certification excludes the capacity check of the building structure to support the loads imposed on the building by the array, such as bending strength of roof rafters spanning between supports. This requires additional knowledge of the building and is outside the scope of the design tool and our review. If you have any questions on the above, do not hesitate to call.

Where an approved racking system is used, provide documentation showing manufacturer of the rack system, maximum allowable weight the system can support, attachment method to the roof or ground and product evaluation information or structural design for the rack system . As a references, the Solar Structural Technical Appendix hyperlink is provided: http://www.opr.ca.gov/docs/Solar_Structural_Technical_Appendix.pdf Inspection Information Once a photovoltaic system permit has been issued and the system has been installed, it must be inspected before final approval is granted. Inspections are required to be scheduled twenty-four (24) hours in advance at: (760) 776- 6420 Monday through Friday (8AM to 4PM) Same day inspection will not be provided. Qualifying small rooftop PV systems will be inspected in one (1) site visit, if under 30 kilowatts. If PV system is over 30 kilowatts it will require a rough inspection after mounting system is installed. If the inspection does not pass, subsequent inspections will not conform to the one inspection policy per the California Solar Initiative AB2188. Permit holders must be prepared to show conformance with all technical requirements in the field at the time of inspection. The inspector will verify that the installation is in conformance with applicable code requirements and with the approved plans. An OSHA approved ladder must be provided by the contractor of record or property owner at the time of inspection. Here are some common points of inspection you should be prepared to show: Number of PV modules and model number match plans and specification sheets number match plans and specification sheets. Array conductors and components are installed in a neat and workman-like manner. PV array is properly grounded. Electrical boxes are accessible and connections are suitable for environment. Array is fastened and sealed according to attachment detail. Conductor’s ratings and sizes match plans. Appropriate signs are properly constructed, installed and displayed. Smoke detector and carbon monoxide alarms are required at final inspection. Page 4 of 4 QUICK TIPS FOR CONTRACTORS & PROPERTY OWNERS WHEN APPLYING FOR A SOLAR PERMIT: Permit applicants can save time and money by following these tips. Take time to review permit requirements of the local jurisdiction. Permitting rules and processes differ am ong different cities and counties. Understanding all local requirements will allow permit applicants to submit a complete and accurate permit application packet the first time. Contact the local electric utility early in the permitting process (solar PV installations). Local electric utilities have a completely separate approval process from the local jurisdiction’s permitting process. Some electric utilities may require that the solar project be reviewed before the local jurisdiction issues a building permit. Pursuing utility approval early in the permit process enables the solar PV system to become operational as soon as possible. Make sure that the solar installation that is built matches the submitted plans. The on-site inspector will verify that the installation aligns with proposed plans and any changes may require corrections and additional inspections.
