Solar Panel Installation
Dear Ms.Grey:
Per your request, we have reviewed the attached layout and photos relating to the installation of solar panels at the
above-referenced site.The following materials and components are proposed in the installation of the solar panels.
Roof Structure:2x6 rafters at 26"O.C.with 13'-0"span
Roof Material:Composition Shingles
Mounting Connections: 5/16"Lag Screw with 2.5"Embedment at 6' O.C.maximum.
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 is by the manufacturer and/or installer.
The adopted building code in this jurisdiction is the 2009 International Residential 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 C
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 3.5 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,effective snow loads will be reduced in the
areas of the panels. The attached calculations'verify the capacity of the connections against wind,the governing load
case. Solar panels will be flush-mounted, parallel to and no more than 6" above the roof surface. Thus, it is our
conclusion that any additional wind or 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.
Very truly yours,
