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 three
sections:
• Section 1 & 3: Roof section consists of 2 x 8 dimensional lumber at 16" on center with 1 x 10
collar ties every 32".
• Section 2: Roof section consists of assumed 2 x 6 dimensional lumber at 16" on center.
The attic space for Section 1 & 3 is unfinished and photos indicate that there was free access to visually
inspect the size and condition of the roof rafters. The attic space for Section 2 is finished and photos
indicate that there was no 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 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
24, 7, and 27 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.
Page 2 of 2
B. Loading Criteria
• 10 PSF= Dead Load roofing/framing 40 PSF= Live Load(around 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 for Section 1 & 3 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
IlY 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, �tH0t

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 representative from our office under my supervision
identifying specific site information including size and spacing of members 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.
5. Previous structural evaluation for the existing solar system completed by Vivint Solar on January,
27 2015.
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 the following:
• Roof Section 1: Roof section is composed of 2x6 dimensional lumber at 16" on center with interior
wall supports 6.83'from the ridge and a single layer of roofing. The attic space is finished and rafter
dimensions were verified by access through the ridge cap.
• Roof Section 2: Roof section is composed of 2x8 dimensional lumber at 16" on center with tx10
collar ties every 32" and a single layer of roofing. The attic space is unfinished and photos indicate
that there was free access to visually inspect the size and condition of the roof members.
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 shingle.
Stability Evaluation:
A. Wind Uplift Loading
1. Calculations for uplift are based on ASCE/SEI 7-10 Minimum Design Loads for Buildings and other
Structures, a wind speed of 100 mph based on Exposure Category B and 24 and 20 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 1 012
B. Loading Criteria
8 PSF= Dead Load (roofing/framing) 40 PSF = Ground Snow Load
3 PSF= Dead Load (solar panels/mounting hardware)
Total Dead Load= 11 PSF
The above values are within acceptable limits of recognized industry standards for similar structures and in
accordance with the 2009 International Residential Code with Massachusetts Amendments. Analysis performed on
the existing roof structure utilizing the above loading criteria indicates that the existing members will support the
additional panel loading without damage, if installed correctly.
C. 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 (www.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.
2. The solar panels are 1 1/2' thick and mounted 4 1/2' off the roof for a total height off the existing roof
of 6". At no time will the panels be mounted higher than 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 Specifications (NDS) of timber construction specifications for Spruce-Pine-Fir assumed.
Based on our evaluation, the pullout value, utilizing a penetration depth of 2 W', is less than the
maximum allowable per connection and therefore is adequate.
4. Roof Sections (1 and 2): Considering the roof slopes, the size, spacing, condition of the roof, the
panel supports shall be placed at and attached no greater than every fourth roof member as panels
are installed perpendicular across members and no greater than the panel length when installed
parallel to the members (portrait). No panel supports spacing shall be greater than four (4) spaces
or 64"o/c, whichever is less.
5. Panel support connections shall be staggered to distribute load to adjacent members.
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 with Massachusetts Amendments, current industry standards and practice, and the
information supplied to us at the time of this report.
Should you have any questions regarding the above or if you require further information do not hesitate to contact

R.E: Zoning 14 Circle Hill Road
Dear Ms. O,Brien,
The property above is a single family home. The two living spaces are connected by an internal
stair. Under Salem Zoning, there would have to be separate entrances to each space and
separation to constitute a two family or two unit building. Hopefully this clears up this issue. If
you have further questions, please feel free to contact me directly.
