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 VisiVVerification 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. Proposed layout of the system including connection details for the solar panels.
3. 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 the following:
• Roof Section: Dimensional lumber - 2x8 at 20" on center. 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 a maximum of two layers of composite shingle.
A. Loading Criteria
9.2 PSF= Dead Load (roofing/framing)
2.4 PSF= Dead Load (solar panels/mounting hardware)
11.6 PSF=Total Dead Load
40 PSF=Ground Snow Load (based on local requirements)
Wind speed of 100 mph (based on Exposure Category B-the total area subject to wind uplift is calculated for the
Interior, Edge, and Corner Zones of the dwelling.)
B.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
Page 1 of vivi t. solar
. ru
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 Yz' thick and mounted 41/z" 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. Based on our evaluation, the
pullout value, utilizing a penetration depth of 21/2", is less than the maximum allowable per connection and
therefore is adequate.
4. The maximum allowed spacing was calculated for the Wind Speed shown in paragraph A above, using the wind
load uplift procedures of ASCE 7-10 and is specified below. The following values have been verified by in-
house testing and the mounting hardware manufacturers' data, which are available upon request. Panel
support connections shall be staggered to distribute load to adjacent members.
Modules in Landscape Modules in Portrait
Roof Zone Interior Ede Corner Interior Ede Corner
Max Vertical Spacing in 40 40 40 66 66 66
Max Horizontal Spacing in 60 60 60 60 60 60
Max Uplift Load Ibs 181 149 141 305 251 1 238
C. Summary
Based on the above evaluation,with appropriate panel anchors being utilized the roof system designed on will
adequately support the additional loading imposed by any solar array size and configuration, if installed correctly.
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
me.
