Re: Structural Engineering Services

AR#3578507
6 kW System
Dear Mr. Rock:
Pursuant to your request, we have reviewed the following information regarding solar panel installation on
the roof of the above referenced home:
1. Site Visit/Verification Form prepared by a Vivint Solar representative identifying specific site
information including size and spacing of rafters for the existing roof structure.
2. Design drawings of the proposed system including a site plan, roof plan and connection
details for the solar panels. This information was prepared by Vivint Solar and will be
utilized for approval and construction of the proposed system.
3. Photovoltaic Rooftop Solar System Permit Submittal prepared by Vivint Solar identifying
design parameters for the solar system.
4. Photographs of the interior and exterior of the roof system identifying existing structural
members and their conditions.
Based on the above information we have evaluated the structural capacity of the existing roof system to
support the additional loads imposed by the solar panels and have the following comments related to our
review and evaluation:
Description of Residence:
The existing residence is typical wood framing construction with the roof system consisting of 2 x 6
dimensional lumber at 16" on center with 2 x 4 collar ties every 96". The attic space is unfinished and
photos indicate that there was free access to visually inspect the size and condition of the roof rafters. All
wood material utilized for the roof system is assumed to be Spruce-Pine-Fir #2 or better with standard
construction components. Our review of the photos of the exterior roof does not indicate any signs of
settlement or misalignment caused by overstressed underlying members.
Stability Evaluation:
A. Wind Uplift Loading
1. Refer to attached ZEP calculations sheet for ASCE/SEI 7-10 Minimum Design Loads for Buildings
and other Structures, wind speed of 100 mph based on Exposure Category "B" and 24 degree roof
slopes on the dwelling areas. Ground snow load is 40 PSF for Exposure"B", Zone 2 per(ASCE/SEI
7-10).
2. Total area subject to wind uplift is calculated for the Interior, Edge and Corner Zones of the dwelling.
Page 2 of 2
B. Loading Criteria
• 10 PSF=Dead Load roofing/framing . 40 PSF = Live Load (ground snow load)
• 5 PSF=Dead Load solar Panels/mounting hardware
Total Dead Load=15 PSF
The above values are within acceptable limits of recognized industry standards for similar
structures. Analysis performed of the existing roof structure utilizing the above loading criteria
indicates that the existing rafters will support the additional panel loading without damage, if
installed correctly.
C. Roof Structure Capacity
1. The photographs provided of the attic space and roof rafters show that the framing is in good
condition with no visible signs of damage caused by prior overstressing.
2. The dwelling owners shall be made aware that long term build-up of heavy snow conditions may
produce deflections in the roof. If any deflection is noticed, then it is recommended that the solar
panels be cleared of accumulated snow more than one (1) foot deep over a period of one week. If
no deflections are visible under any snow loading over a period of time, then there is no need to
clear the solar panels.
D. Solar Panel Anchorage
1. The solar panels shall be mounted in accordance with the most recent "ZEP Code Compliant
Installation Manuaf', which can be found on the ZEP website (zepsolar.com). If during solar panel
installation, the roof framing members appear unstable, deteriorated, structurally compromised or
deflect non-uniformly, our office should be notified before proceeding with the installation.
2. Maximum allowable pullout per lag screw is 235 Ibs/inch of penetration as identified in the National
Design Standards (NDS) of timber construction specifications for Hem-Fir(North Lumber) assumed.
Based on our evaluation, the pullout value, utilizing a penetration depth of 2 '/z", is less than what is
allowable per connection and therefore is adequate. Based on the variable factors for the existing
roof framing and installation tolerances, using a thread depth of 2 ''/s' with a minimum size of 5/16"
lag screw per attachment point for panel anchor mounts should be adequate with a sufficient factor
of safety.
3. Considering the roof slopes, the size, spacing, condition of roof, the panel supports shall be placed
at and attached to no greater than every fourth roof rafter as panels are installed perpendicular
across rafters and no greater than the panel length when installed parallel to the rafters (portrait).
No panel supports spacing shall be greater than four(4) rafter spaces or 64" o/c, whichever is less.
4. Panel supports connections shall be staggered to distribute load to adjacent rafters.
Based on the above evaluation, it is the opinion of this office that with appropriate panel anchors being utilized
the roof system will adequately support the additional loading imposed by the solar panels. This evaluation is
based on information supplied to us at the time of this report and current industry standards and practices.
Should you have any questions regarding the above or if you require further information do not hesitate to
contact me. Ae
