The following materials and components are proposed in the installation of the solar panels. Roof Structure: 2x8 Rafters at 16" O.C. Roof Material: Composite Shingles Based upon our review, it is our conclusion that the installation of solar panels on this existing roof will not adversely affect the structure of this house. The design of solar panel supporting members and connections is by the manufacturer and/or installer. The adopted building code in this jurisdiction is the 2009 International Building Code and ASCE 7-05. Appropriate design parameters which must be used in the design of the supporting members and connections are listed below: Ground snow load: 50 psf per Massachusetts amendments to the IRC (verify with local building department) Design wind speed for risk category II structures: 105 mph (3 -sec gust) Wind exposure: Category B Our conclusion regarding the adequacy of the existing roof is based on the fact that the additional "weight related to the solar panels is less than 3 pounds per square foot. In the area of the solar panels, no 20 psf live loads will be present. Regarding snow loads, it is our conclusion that since the panels are slippery and dark, effective snow loads will likely be reduced in the areas of the panels. Solar panels will be flush -mounted, parallel to and no more than 6" above the roof surface. Regarding wind loads, we conclude that any additional forces will be negligible due to the low profile of the flush -mounted panel system. It is our conclusion that any additional seismic loadings related to the addition of these solar panels is negligible. During design and installation, particular attention must be paid to the maximum allowable spacing of attachments and the location of solar panels relative to roof edges. The use of solar panel support span tables provided by the manufacturer is allowed only where the building type, site conditions, and solar panel configuration match the description of the span tables. Attachments to existing roof joist or rafters must be staggered so as not to over load any existing structural member. Waterproofing around the roof penetration is the responsibility of others. All work performed must be in accordance with accepted industry -wide methods and applicable safety standards. Vector Structural Engineering assumes no responsibility for improper installation of the solar panels. Please note a representative of Vector Structural Engineering has not physically observed the roof framing. Our conclusions are based upon the site assessment and information provided by Revolusun and the understanding that all structural roof components and other supporting elements are in good condition, free of damage and deterioration, and are sized and spaced as outlined in the site assessment performed by Revolusun.
