Solar Array Installation
To Whom It May Concern:
We have reviewed the documents provided by Brio Energy relating to the installation of the solar array at the above-
referenced site.Based upon our review,it is our conclusion that the installation of the solar array on this existing roof will
not adversely affect this structure.It is our understanding that the structural components of the existing roof framing are in
good condition and free of damage.The design of the solar panel racking (mounts,rails,etc.)and connections to the roof is
by the manufacturer or contractor.Please note a representative of Vector Structural Engineering has not physically observed
the roof framing.
Design Parameters
Code: International Building Code, 2015 Edition
Risk Category: II
Design wind speed: 115 mph (3-sec gust) per ASCE 7-10
Wind exposure category: C
Ground snow load: 35 psf
Existing Roof Structure
Roof structure: 2x4 built-up trusses @ 24" O.C.
Roofing material: composite shingles
Conclusions
Our conclusion regarding the adequacy of the existing roof is based on the fact that the additional weight of the solar array is
3 psf or less.In the area of the solar array,other live loads will not be present or will be greatly reduced (2015 IBC,Section
1607.12.5).The member forces in the area of the solar panels are not increased by more than 5%;thus,the stresses of the
structural elements are not increased by more than 5%.Therefore,the requirements of Section 807.4 of the 2015 IEBC are
met and the structure is permitted to remain unaltered.

The solar array will be flush-mounted (no more than 6"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.
Regarding seismic loads,we conclude that any additional forces will be small.With an assumed roof dead load of 10 psf,
solar array dead load of 3 psf,and affected roof area of 33%(maximum),the additional dead load (and consequential seismic
load)will be 9.5%.This calculation conservatively neglects wall weight.Because the increase in lateral forces is less than
10%,this addition meets the requirements of the exception in Section 807.5 of the 2015 IEBC.Thus the existing structure 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 shall 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.Particular attention must be paid to the maximum allowable
spacing of connections and the location of solar panels relative to roof edges.Connections to existing roof framing must be
staggered so as not to overload any existing structural member,except at array ends.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.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 assumes no responsibility for the
effects of snow falling from roofs onto other roofs, property or persons due to the installation of the solar array.
