Our analysis is based upon the original drawings and specifications provided by Sunsense on September 21, 2012. We have also reviewed the existing roof framing based upon existing structural drawings provided by Venture Architecture, designed by Engineering Designworks dated April 4, 2012. The existing conditions shall be verified by contractor prior to construction. We shall be notified if conditions are found to differ from that shown on the referenced set of existing structural drawings or as stated within. The applicable current codes are the 2009 International Residential Code and the 2009 International Building Code per the Town of Vail. The applicable structural design criteria are as follows: Roof Dead Load 20 psf (assumed, including 3.4 psf PV panel & rack) Snow Load 80 psf (7/12 pitch) & 100 psf (4/12 pitch) Wind Criteria 90 mph, Exposure C The existing roof framing is 5/8" OSB APA rated sheathing, 40/20, spanning perpendicular over 117/8" I joist or LVL rafters, spaced at a maximum of 24 "o.c. The sheathing is attached to the rafters with 8d common nails at 6 "o.c. at panel edges and at 12 "o.c. to intermediate framing members. The design of the panels, the panel racks and connections between shall be per the manufacturer for the applicable design criteria. For the layout and attachment of the racks to the roof refer to the Sunsense Fastening Layout on P -05, dated October 4, 2012. Power -Fab Easy Posts shall be used for the roof connections. Each Easy Post shall be attached with (6)'/4" x 1 '' /z" RSS PHEinox screws, installed per manufacturer. Screws shall have full penetration through the sheathing, contractor shall verify in field. All posts shall be located over the rafters, with a maximum tolerance of 3" between center of rafter to center of post. Per the design criteria, assumptions and recommendations stated above, it is our professional opinion that the existing roof structure is adequate for the proposed PV panel addition. Should you have any further questions regarding this matter, please feel free to contact our office. Sincerely, Evolve Structural Design LLC Sara Mickus, P.E.

SL -SS -1082 10.10.2M POWER RAIL TM P8 Solar Mounting System PV module mounting system engineered to reduce installation costs and provide maximum strength for longer span, parallel -to -roof or tilt up mounting applications. The Power Rail P8 top - clamping mounting system is designed with the professional PV solar installer in mind. The high strength top - clamping system features an easy to slide carriage bolt or the revolutionary RAD T' Fastener for faster bolt placement. The unique shape of the RAD provides an anti - rotation feature, locking the bolt in the proper orientation when installed. The long Features High Strength, Reliable Design • Capable of longer span and cantilevered distances — less roof penetrations • Engineered profile for maximum strength to weight ratio • Structural Aluminum construction and corrosion resistant ■ High Strength stainless steel module clamps and hardware Reduced Installation Time and Costs ■ Longer spans — less mounting supports ■ Single Tool Assembly — all 5/16" hardware ■ RAD Fastener for quicker bolt placements ■ Top- Clamping design for easier access ■ Integral Wiring Channel for faster securing of cables ■ Standard lengths up to 27 feet eliminate costly rail splices ■ WEEB Integral module grounding option spanning P8 rail reduces the number of roof penetrations and also features an integral wiring channel for securing cables and providing a professional finish. The P8 mounting system features the same field proven mounting supports from the Power Rail family, designed for secure and water tight attachments to any style roof. Flexible Mounting Options ■ Top or bottom module clamping options ■ Height adjustable "L" mounting feet ■ Tilt Legs up to 25 degrees • Solid Aluminum Power POStTM stanchions • Easy FeetTM attachment anywhere on metal or composite roof decking ■ PV Flashing hardware Standard Rail Lengths Part # Length P8 -84 84" P8 -126 126" P8 -162 162" P8 -204 204" P8 -240 240" P8 -282 282" P8 -324 324" P8 Rail — Span and Cantilever Distances (inches) Exposure C Category, please refer to design guidelines and ASCE requirements for more information.
