Solar Array Installation
To Whom It May Concern:
We have reviewed the existing structure at the above referenced site.The purpose of our review was to determine the
adequacy of the existing structure to support the proposed installation of solar panels on the roof as shown on the panel
layout plan.
Based upon our review, we conclude that the existing structure is adequate to support the proposed solar panel installation.
Design Parameters
Code: Massachusetts State Residential Code (780 CMR Chapter 51, 9th Edition (2015 IRC))
Risk Category: II
Design wind speed, Vult: 117 mph (3-sec gust)
Wind exposure category: C
Ground snow load, Pg: 40 psf
Flat roof snow load, Pf: 35 psf
Existing Roof Structure
Roof structure: 2x10 rafters @ 16" o.c.
Roof slope: 36°
Conclusions
Based upon our review,we conclude that the existing structure is adequate to support the proposed solar panel installation.
See attached calculations.
The solar array will be flush-mounted (no more than 10"above the roof surface)and parallel to the roof surface.Thus,we
conclude that any additional wind loading on the structure related to the addition of the proposed solar array is negligible.
Increases in lateral forces less than 10%are considered acceptable.Thus the existing lateral force resisting system is
permitted to remain unaltered.

Limitations
Installation of the solar panels must be performed in accordance with manufacturer recommendations.All work performed
must be in accordance with accepted industry-wide methods and applicable safety standards.The contractor must notify
Vector Structural Engineering,LLC should any damage,deterioration or discrepancies between the as-built condition of the
structure and the condition described in this letter be found.The use of solar panel support span tables provided by others is
allowed only where the building type,site conditions,site-specific design parameters,and solar panel configuration match
the description of the span tables.Connections shall be staggered so as not to overload any existing structural member.The
design of the solar panels,solar racking (mounts,rails,etc.),the connection of the racking to the roof and electrical
engineering is the responsibility of others.Waterproofing around the roof penetrations is the responsibility of others.Vector
Structural Engineering assumes no responsibility for improper installation of the solar array.Vector Structural Engineering
shall be notified of any changes from the approved layout prior to installation.
