Solar Array Installation
To Whom It May Concern:
Per your request, 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:California Building Code,2016 Edition(2015 IBC)
Risk Category:II
Design wind speed: 110 mph (3-sec gust)per ASCE 7-10
Wind exposure category:C
Existing Roof Structure
Roof structure:2x4 rafters @ 24"O.C.
Roofing material:concrete tile(flat)
Connection to Roof
Mounting connection:(2) 1/4" lag screws w/min.2.5"embedment into framing at max.72"O.C.along rails
Conclusions
Based upon our review,we conclude that the existing structure is adequate to support the proposed solar panel installation.
In the area of the solar array,other live loads will not be present or will be greatly reduced(2016 CBC, Section 1607.12.5).
The gravity loads, and thus the stresses of the structural elements in the area of the solar array are either decreased or
increased by no more than 5%. Therefore,the requirements of Section 403.3 of the 2016 CEBC are met and the structure is
permitted to remain unaltered.
651 W.Galena Park Blvd.,Ste.101/Draper,UT 84020/T(801)990-1775/F(801)990-1776/www.vectorse.com

VSE Project Number:U3324.0112.191
%/E C T O R Kai Tung Tang Address
9/28/2019
E Il S I n E E R S
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.
The attached calculations verify the capacity of the connections of the solar array to the existing roof against wind (uplift),
the governing load case. Regarding seismic loads, we conclude that any additional forces will be small. Conservatively
neglecting the weight of existing wall materials,the installation of the solar panels represents an increase in the total weight
(and resulting seismic load) of 4.8%. Because the increase in lateral forces is less than 10%, this addition meets the
requirements of the exception in Section 403.4 of the 2016 CEBC. 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. Connections to existing roof framing must be staggered,except
at array ends,so as not to overload any existing structural member. 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.The design of the solar panel racking(mounts,rails,etc.),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.
