Northwestern Territories, Inc. 914 Washington Street, Suite 6 Port Townsend, WA 98368 Dear Mr. Anderson, I have prepared drawings for you of a solar array for John Warder's residence located at 1122 South E. Street in Port Angeles. Mr. Warder has contracted with Power Trip Energy to install a 3.4 kW Silicon Energy solar array on the flat roof of his home. The city of Port Angeles handles the electrical permit and requires a building permit also be obtained prior to the installation of a solar PV system. I have attached the city of Port Angeles FAQ sheet for residential solar installations. This handout indicates that two sets of plans must be prepared which show: 1. The solar array can handle a minimum of 25 psf snow load and 100 mph winds; and, 2. Roof construction details be provided to show that the roof can handle the additional weight of the solar modules. We request your assistance in providing the necessary calculations and drawings to obtain the city building permit. Per our previous projects of this type you estimated the cost to do this would be about$500. Please let me know if this project will be significantly different in cost. Issue 1: Solar Modules and Minimum 25 PSF Snow Load This issue is pretty straightforward and is addressed by an engineering letter from WJE Engineering from Seattle (see attached). The letter documents that the Silicon Energy solar modules have a design load that meets 125 PSF. The city of Port Angeles accepted this stamped letter for the Maloney Heights solar array. Issue 2: Solar Modules and Minimum 100 MPH Wind I have attached a stamped letter from Eric Lenz, structural engineer with Coughlin Porter Lundeen from Seattle which documents that the Silicon Energy solar equipment will withstand 100 mph basic wind speed. The city of Port Angeles accepted this letter for the Maloney Heights and McMahon residence solar arrays. This system will be different from these prior installations in that it will be racked up on a flat roof using SunModo racking equipment. I have attached a second letter from Joseph Payne, 1 P.E., S.E.,Appollo Consulting Engineering indicating that for an installation of 20-degree tilt on a roof height of 20-ft,the wind forces are 21.3 psf of uplift and 13.4 psf of downforce,per components and cladding design criteria in section 6.4.2.2 of ASCE 7-05. The Apollo engineering letter also states, "[b]ased on the UL 1703 testing criteria, the Silicon Energy Cascade Series module can resist loads up to 125 psf when properly installed with its aluminum frame mounted foot supported at 2 locations along each side. Two SunModo Helio Standard Rails will be connected to each module as required by the Silicon Energy installation guidelines." The Apollo Engineering letter concludes, "[b]ased on combined snow, wind, and dead loads, loading is significantly lower than the allowable 125 psf on the module, and the SunModo rail is cabable of spanning 6'0"between support points. The design is in compliance with the 2009 International Building Code." Issue 3: Roof Construction Detail and Weight of Solar Modules This is the issue you have addressed in the past. See the building description, array weights and point loads, and construction details below. Array PSP Weight and Point Loads The Silicon Energy solar modules, framing, and hardware weigh 3.9 psf(per their specification sheet) for a total module weight of 1060.8 pounds. The total weight of the aluminum support rails are 0.43 psf(2 rails at 0.85 plf over a 4 ft. width), and all other associated hardware are estimated at 0.5 psf, for an additional 130.6 pounds. With attachments the weight of the system would be 1,229 pounds or 4.8 psf, so a dead load of 5 psf can conservatively be used. With 2 support points at 6 ft. o.c. in the east-west direction supporting modules approximately 4 ft. wide, the point dead load for each attachment point will be 60 LB. (Description of Warder House and hoof System Mr. Warder's home is different from our prior projects in Port Angeles in that it has a flat roof. The roof has 2"x 6"car decking over 6" W x 16"H x 15' to 17' long rafters (6' on center). A torch down roof covers the whole area. There is a 9" W x 20"H x 25' long concrete beam (reinforced with rebar)running midspan. The house has 2"x 4"walls and there is a 3" steel post under each end of the concrete beam. I have attached a sketch of the home including details of the roof construction and the solar array layout. I have also attached the SunModo (Apollo Engineering) letters and specification sheets for the racking system. Photos of Dome The solar array will be on a flat roof on a one story portion of the home. The home has been added to over time and portions of the home have a daylight basement(not the part of home where we propose the array). It is located in an urban setting on gently sloping land (approximately 10 degrees slope). Please see the attached sketches and photos to explain the house roof construction. 2 8 solar modules in a single row on north end. 6 modules in front row. 3 modules in middle row.

(WJE) has reviewed the mechanical load test results reported by Intertek, an Occupational Safety & Health Administration (OSHA) Nationally Recognized Testing Laboratory (NRTL), for the Cascade PV Module assembly including the module and mounting system manufactured by Silicon Energy. The Cascade PV Module assembly is described in Cascade PV Module Manual Revision 3, and the Cascade System Installation Guide Revision 2. The PV Module assembly is approximately 51-3/4 inches wide by 47-1/2 inches long and consists of two layers of 1/8 inch thick tempered glass laminated together and attached to an 1/8 inch thick aluminum frame mounting foot. Silicon Energy has asked that we review the relevant mechanical load test results and report our findings in this letter. We have reviewed the relevant portions of the Intertek test report titled Listing Constructional Data Report issued June 23, 2009, and revised August 3, 2010. Load testing was conducted by Intertek in accordance with the test standard Flat-Plate Photovoltaic Modules and Panels- UL 1703 dated March 15, 2002(UL 1703) Section 41 Mechanical Loading Test.According to the test report,the design load for the Cascade PV Module assembly confirmed by the testing is 125 pounds per square-foot (psf). The Silicon Energy PV Models covered by the test report include the following: SiE-150, SiE-155, SiE-160, SiE-165, SiE-170, SiE-175, SiE-180, SiE-185, SiE-190, SiE-195, and SiE-200. It is reported that these models are identical in every construction detail,and differ only in cell efficiency and electrical rating. Sincerely, WISS,JANNEY,ELSTNER ASSOCIATES,INC.

Street Port Angeles, WA 98363 Dear Tony: I have analyzed the SunModo Helio Standard aluminum rail for its use with the Silicon Energy Cascade Series solar module.The following load criteria were used based on City of Port Angeles requirements: • Roof snow load =25 psf • Basic Wind Speed = 100 mph, Exposure Category C( >1,500 ft from shoreline) For an installation of 20-degree tilt on a roof height of 20-ft, the wind forces are 21.3 psf of uplift and 13.4 psf of downforce, per components and cladding design criteria in section 6.4.2.2 of ASCE 7-05. Based on the UL 1703 testing criteria,the Silicon Energy Cascade Series module can resist loads up to 125 psf when properly installed with its aluminum frame mounted foot supported at 2 locations along each side.Two SunModo Helio Standard rails will be connected to each module as required by the Silicon Energy installation guidelines. Based on combined snow,wind, and dead loads, loading is significantly lower than the allowable 125 psf on the module, and the SunModo rail is capable of spanning 6'-0" between support points. This design is in compliance with the 2009 International Building Code. Please let me know if you have any additional questions. Sincerely, c�^ S�Yx F NJ,S�. �Y WASFIt�r��' Joseph Payne, P.E., S.E.

This was done to satisfy the City requirement for a licensed engineer's opinion on structural adequacy of this roof to support new solar panels. As you know, the roof must hold 25 pounds per square foot snow load, the existing dead load and an additional 5 psf for solar panels. Panel locations are shown on the roof framing plan you provided. You also provided geometry of the existing roof system, panel attachment details, and engineer letters of verification for panel attachment adequacy. Our work was strictly related to roof framing adequacy. Engineering calculations for this analysis are attached. This house has a flat roof. Framing consists of 6x16 inch timber beams, spaced 6 feet apart. They are supported by 2x4 stud walls at the house exterior and by a 9x20 inch concrete beam at the house center. There is 2x6 decking between beams. In my analysis I used 16 psf dead load, the 5 psf panel load and the required 25 psf snow load. Engineering calculations for this analysis are attached. My analysis indicates that the existing roof system will adequately support the solar panels you propose to use. My only recommendation is that you change the SunModo panel support equipment legs from 4 foot spacing to 6 foot spacing. (This is acceptable according to Joseph Payne, PE; Apollo Consulting Engineering; in a 7-9- 13 letter to the SunModo Corporation, attached.) This revised spacing will place all roof to support connections at the 6x16 beams and not on decking between beams. Use two 3/8-inch diameter lag bolts at each leg with a minimum of 2-inches penetration into the 6x16 beam. .S� trust that the City will be satisfied with this level of analysis. However, if you or the City require additional information, please let me know. I am happy to provide whatever else may be needed.
