From a field inspection of the property,the existing roof support structures were observed by the client's auditors as follows: The roof structure of(MP1)consists of composition shingle on roof plywood that is supported by nominal 2x8 rafters @ 16"o.c.,paired with nominal 2x8 ceiling joists @ 16"o.c..The rafters have a max projected horizontal span of 14'-0",with a slope of 30 degrees.The rafters are connected at the ridge to a continuous 2x10 ridge board and are supported at the eave by a load bearing wall. There are 1x8 collar ties @ 32"o.c.for structural stability.There are also 1x10 collar ties at 16"o.c.in other areas of attic. The roof structure of(MP2)consists of composition shingle on roof plywood that is supported by nominal 2x10 rafters @ 16"o.c.,paired with nominal 2x10 ceiling joists @ 16"o.c..The rafters have a max projected horizontal span of 13'-0", with a slope of 30 degrees.The rafters are connected at the ridge to a continuous 2x12 ridge board and are supported at the eave by a load bearing wall. The existing roof framing system of(MP1)is judged to be inadequate to withstand the loading imposed by the installation of the solar panels.Structural reinforcement is required. Sister upgrade is required for(MP1).Stitch new 12'- 0"long 2x8 SPF#2 or DF#2(min)to existing member with Simpson SDW 22300 screws @ 16"o.c. or 10d nails @ 6"o.c.. The existing roof framing system of(MP2)is judged to be adequate to withstand the loading imposed by the installation of the solar panels. No reinforcement is necessary. The spacing of the solar standoffs should be kept at 48"o.c.with a staggered pattern to ensure proper distribution of loads. I further certify that all applicable loads required by the codes and design criteria listed below were applied to the Invisimount solar rail system and analyzed. Furthermore,the installation crews have been thoroughly trained to install the solar panels based on the specific roof installation instructions developed by Invisimount for the racking system and Sunmodo for the roof connections. Finally, I accept the certifications indicated by the solar panel manufacturer for the ability of the panels to withstand high wind and snow loads.

Document#509506 Rev I i STRUCTURAL ENGINEERS 4 November 24, 2014 SunPower Corporation 1414 Harbour Way South Richmond, CA 94804 TEL: (510) 540-0550 Attn.: Engineering Department, Re: Engineering Certification for the SunPower Corporation Invisimount Design Tool This letter is to document that PZSE, Inc.-Structural Engineers has reviewed SunPower's Invisimount Design Tool, an online tool that: • Evaluates structural design loads on SunPower Invisimount solar arrays • Evaluates the maximum allowable spacing of attachments of the system to the roof to resist design loads • Estimates the bill of materials for specific projects to assist with ordering parts from SunPower SCOPE OF THE TOOL: Invisimount by SunPower is a solar panel support system for installing solar photovoltaic arrays on sloped roofs of buildings. Typically such buildings are residential with shingle or tile roofs. Each row or column of modules is supported by two rails,which are attached to the roof structure. The number and spacing of attachments to the roof structure can vary depending on, for example, structural loads at a particular site,the type of attachment hardware used, and spacing of the supporting roof structural members. SCOPE OF OUR REVIEW: PZSE, Inc.—Structural Engineers provided a review of the following • Invisimount online Design Tool algorithm and design methodology and has determined that the Invisimount Design Tool is a rational approach and is in compliance with the structural requirements of the following Reference Documents: 1. Minimum Design Loads for Buildings and other Structures,ASCE/SEI 7-05 2. International Building Code,2009 Edition, by International Code Council, hic. 3. Aluminum Design Manual, 2005 Edition,by The Aluminum Association 4. AC428,Acceptance Criteria for Modular Framing Systems Used to support Photovoltaic (PV)Panels, November 1,2012 by ICC-ES This letter certifies that the Invisimount online Design Tool is in compliance with the above Reference Documents. 8150 Sierra College Boulevard,Suite 150 * Roseville,CA 95661 * 916.961.3960 P * 916.961.3965 * www.pzse.com Page 1 of 2 �oii ✓%//�%/ %X me i� STRU(TURALENGINEERS DESIGN RESPONSIBILITY: The Invisimount Design Tool is intended to be used under the responsible charge of a registered design professional where required by the authority having jurisdiction. In all cases,the tool should be used under the direction of a design professional with sufficient structural engineering knowledge and experience to be able to: • Evaluate whether the tool is applicable to the project, based on the "Engineering Basis of Calculations"document and the characteristics of the project, and • Understand and determine the appropriate values for all input parameters of the tool. Results of the tool should be checked against the design professional's judgment. Excerpts from standards such as ASCE 7-10 are presented in the tool as pointers to the standard and are not intended to diminish the user's responsibility to consult the applicable figures and sections of the standard directly. The user or design professional in responsible charge assumes full design responsibility. The tool does not check the capacity 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. Please feel free to contact me at your convenience if you have any questions.
