The SolarEdge power optimizers increase energy output from PV systems by constantly tracking the maximum power point (MPPT) of each module individually. Furthermore, the power optimizers monitor the performance of each module and communicate performance data to the SolarEdge monitoring portal for enhanced,cost-effective module-level maintenance.Each power optimizer is equipped with the unique SafeDC'm feature which automatically shuts down modules'DC voltage whenever the inverter or grid power is shut down. The MPPT per module allows for flexible installation design with multiple orientations,tilts and module types in the same string. When working with SolarEdge Inverters,SolarEdge power optimizers automatically maintain a fixed string voltage,allowing installers even greater flexibility with longer strings and strings of different lengths in order to design optimal PV systems. The SolarEdge power optimizers are compatible with c-Si and thin-film modules and have a 25 year warranty.

Loading Criteria 10 PSF= Dead Load roofing/framing 40 PSF= Live Load (ground snow load) 5 PSF= Dead Load solar panels/mounting hardware Total Dead Load=15 PSF The above values are within acceptable limits of recognized industry standards for similar structures and in accordance with the 2009 International Residential Code. Analysis performed of the existing roof structure utilizing the above loading criteria indicates that the existing rafters will support the additional panel loading without damage, if installed correctly. C. Roof Structure Capacity 1. The photographs provided of the attic space and roof rafters show that the framing is in good condition with no visible signs of damage caused by prior overstressing. D. Solar Panel Anchorage 1. The solar panels shall be mounted in accordance with the most recent "Ecolibrium Solar Installation Manual', which can be found on the Ecolibrium Solar website (ecolibrium solar.com). 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. 2. The solar panels are 1 1/2"thick and mounted 4 1/2"off the roof for a total height off the existing roof of 6". At no time will the panels be mounted higher that 6"above the existing plane of the roof. 3. Maximum allowable pullout per lag screw is 235 Ibs/inch of penetration as identified in the National Design Standards (NDS) of timber construction specifications for Hem-Fir (North Lumber) assumed. Based on our evaluation, the pullout value, utilizing a penetration depth of 2 1/2", is less than the maximum allowable per connection and therefore is adequate. Based on the variable factors for the existing roof framing and installation tolerances, using a thread depth of 2 1/2" with a minimum size of 5/16" lag screw per attachment point for panel anchor mounts will be adequate with a sufficient factor of safety. 4. Considering the roof slopes, the size, spacing, condition of roof, the panel supports shall be placed at and attached to no greater than every other roof rafter as panels are installed perpendicular across rafters and no greater than the panel length when installed parallel to the rafters (portrait). No panel supports spacing shall be greater than two (2) rafter spaces or 48" o/c, whichever is less. 5. Panel supports connections shall be staggered to distribute load to adjacent rafters. Based on the above evaluation, with appropriate panel anchors being utilized the roof system will adequately support the additional loading imposed by the solar panels. This evaluation is in conformance with the 2009 International Residential Code, current industry standards and practice, and based on information supplied to us at the time of this report.

Wyssling, PE Head of Structural Engineering scott.wyssling@vivintsolar.com April 20,2015 Mr. Dan Rock, Project Manager Vivint Solar 150 Padgette Street, Unit A Chicopee, MA 01022 Re: Structural Engineering Services Hall Residence 86 N Maple St, Florence MA S-4226375 3.06 kW System Dear Mr. Rock: Pursuant to your request, we have reviewed the following information regarding solar panel installation on the roof of the above referenced home: 1. Site Visit/Verification Form prepared by a Vivint Solar representative identifying specific site information including size and spacing of rafters for the existing roof structure. 2. Design drawings of the proposed system including a site plan, roof plan and connection details for the solar panels. This information was prepared by the Design Group and will be utilized for approval and construction of the proposed system. 3. Photovoltaic Rooftop Solar System Permit Submittal identifying design parameters for the solar system. 4. Photographs of the interior and exterior of the roof system identifying existing structural members and their conditions. Based on the above information we have evaluated the structural capacity of the existing roof system to support the additional loads imposed by the solar panels and have the following comments related to our review and evaluation: Description of Residence: The existing residence is typical wood framing construction with the roof system consisting of 2x6 dimensional lumber at 24" on center. The attic space is unfinished and the photos indicate that there was free access to visually inspect the size and condition of the roof rafters. All wood material utilized for the roof system is assumed to be Spruce-Pine-Fir #2 or better with standard construction components. Our review of the photos of the exterior roof does not indicate any signs of settlement or misalignment caused by overstressed underlying members. Stability Evaluation: A. Wind Uplift Loading 1. Refer to attached Ecolibrium Solar calculations sheet for ASCE/SEI 7-10 Minimum Design Loads for Buildings and other Structures, wind speed of 90 mph based on Exposure Category"B"and 45 degree roof slopes on the dwelling areas. Ground snow load is 40 PSF for Exposure "B", Zone 3 per(ASCE/SEI 7-10). 2. Total area subject to wind uplift is calculated for the Interior, Edge and Corner Zones of the dwelling. vivint. f The Commonwealth of Massachusetts Department of Industrial Accidents Ulf Office of Investigations I Congress Street,Suite 100 Boston,MA 02114-2017 www mass.gov/dia Workers'Compensation Insurance Affidavit: Builders/Contractors/Electricians/Plumbers Applicant information Please Print Legibly Name (Business/Organization/Individual): Vivint Solar Developer, LLC Address:3301 North Thanksgiving Way,Suite 500 City/State/Zip:Lehi, UT 84043 Phone#:801-377-9111 Are you an employer?Check the appropriate box: Type of project(required): 1.V lam a employer with 214 4. ❑ I am a general contractor and I 6. ❑New construction employees(full and/or part-time).* have hired the sub-contractors 2.❑ I am a sole proprietor or partner- listed on the attached sheet. 7. ❑Remodeling ship and have no employees These sub-contractors have g_ ❑Demolition working for me in any capacity. employees and have workers' 9. ❑Building addition [No workers' comp. insurance comp.insurance.$ required.] 5.
