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 2 x 6
dimensional lumber at 16" on center with 1 x 8 collar ties every 32". 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 b overstressed underlying members.

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
22 degree roof slopes on the dwelling areas. Ground snow load is 40 PSF for Exposure"B", Zone
2 per (ASCE/SEI7-10).
2. Total area subject to wind uplift is calculated for the Interior, Edge and Corner Zones of the
dwelling.
vivi t. solar
4 y 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.
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, 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
1/2", 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
11F 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.
Ve truly yours, o=��tNOFSSgry�
