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 the Design Group and will be utilized for
approval and construction of the proposed system.
3. Photovoltaic Rooftop Solar System Permit Submittal 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 2x6 dimensional
lumber at 16" on center with 1 x8 collar ties every 32". The attic space is unfinished and the 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. The existing
roofing material consists of composite asphalt shingles. 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 Ecolibrium Solar 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
18 degree roof slopes on the dwelling areas. Ground snow load is 40 PSF for Exposure "B", Zone
2 per (ASCE/SEl7-10).
2. Total area subject to wind uplift is calculated for the Interior, Edge and Corner Zones of the
dwelling.
dubont. solar
;e
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/mountinq hardware
Total Dead Load=15 PSF
The above values are within acceptable limits of recognized industry standards for similar structures and in
accordance with the 2009 International Residential Code. 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.
D. Solar Panel Anchorage
1. The solar panels shall be mounted in accordance with the most recent "Ecolibrium Solar
Installation Manual', which can be found on the Ecolibrium Solar website (ecolibriumsolar.com). If
during solar panel installation, the roof framing members appear unstable or deflect non-
uniformly, our office should be notified before proceeding with the installation.
Y P 9
2. The solar panels are 1 1/2"thick and mounted 4 'W'off the roof for a total height off the existing roof
of 6". At no time will the panels be mounted higher that 6" above the existing plane of the roof.
3. Maximum allowable pullout per lag screw is 205 Ibs/inch of penetration as identified in the
National Design Standards (NDS) of timber construction specifications for Spruce-Pine-Fir
assumed. Based on our evaluation, the pullout value, utilizing a penetration depth of 2 Yi', is less
than the maximum 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 IlY with a
minimum size of 5/16" lag screw per attachment point for panel anchor mounts will be adequate
with a sufficient factor of safety.
4. Considering the roof slopes, the size, spacing, condition of roof, the panel supports shall be
r installed
laced at and attached to no realer than ever fourth roof rafter aspanels a e sta
p 9 Y
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 rafters aces or 64" o/c,
(P ) P PP P 9 9 ( ) P
whichever is less.
5. Panel supports connections shall be staggered to distribute load to adjacent rafters.
Based on the above evaluation, with appropriate panel anchors being utilized the roof system will adequately support
the additional loading imposed by the solar panels. This evaluation is in conformance with the 2009 International
Residential Code current industrystandards and practice, and based on information supplied to us at the time of
P PP
this report.
Should you have any questions regarding the above or if you require further information do not hesitate to contact me.
