Subject: Structural Certification for Installation of Solar Panels
Athuluri Residence -
18 Saunders Street
Salem, MA.01970
To Whom It May Concern,
A design check for the subject residence was done on the existing roofing and framing systems for the installation of
solar panels over the roof. From a field inspection of the property,the existing roof support structures were observed by
the client's auditors as follows:
The roof structure of(MP1)consists of composition shingle on roof plywood that is supported by nominal 2x10 rafters @
16"o.c., paired with nominal 2x10 ceiling joists @ 16"o.c..The rafters have a max projected horizontal span of 13'-0",
with a slope of 36 degrees.The rafters are connected at the ridge to a continuous double 2x12 ridge board and are
supported at the eave by a load bearing wall. There are 2x8 collar ties @ 16"o.c.for structural stability..
The existing roof framing system of(MP1) is judged to be adequate to withstand the loading imposed by the installation
of the solar panels. No reinforcement is necessary.
The spacing of the solar standoffs should be kept at 48"o.c.with a staggered pattern to ensure proper distribution of
loads.
I further certify that all applicable loads required by the codes and design criteria listed below were applied to the
Invisimount solar rail system and analyzed. Furthermore,the installation crews have been thoroughly trained to install
the solar panels based on the specific roof installation instructions developed by Invisimount for the racking system and
Sunmodo for the roof connections. Finally, I accept the certifications indicated by the solar panel manufacturer for the
ability of the panels to withstand high wind and snow loads.
Design Criteria:
• Applicable Codes=Massachusetts Residential Code,8th Edition,ASCE 7-05,and 2005 NDS
• Roof Dead Load=9 psf(MP1)
• Roof Live Load=20 psf
• Wind Speed=100 mph, Exposure C
• Ground Snow Load =40 psf - Roof Snow Load =28 psf
Please contact me with any further questions or concerns regarding this project.

f Check Bending Stress
Fb(psi)= fb x Cd x Cf x Cr (NDS Table 4.3.1)
875 x 1.15 x 1.1 x 1.15
Allowed Bending Stress= 1272.9 psi
Maximum Moment = (wL.A2)/8
= 1214.68 ft#
= 14576.1 in#
Actual Bending Stress=(Maximum Moment)/S
=681.5 psi
Allowed>Actual--53.6%Stressed -- Therefore,OK
- Check Deflection
Allowed Deflection(Total Load) = U180 (E=1400000 psi Per NDS)
= 0.866 in
Deflection Criteria Based on = Simple Span
Actual Deflection(Total Load) _ (5*w*LA4)/(384*E*1)
= 0.267 in
= U585 > U180 Therefore OK
Allowed Deflection(Live Load) = U240
0.65 in
Actual Deflection(Live Load) _ (5*w*LA4)/(384*E*1)
0.174 in
U897 > U240 Therefore OK
Check Shear i
Member Area= 13.9 inA2 Fv(psi)= 135 psi (NDS Table 4A)
Allowed Shear = Fv*A = 1873 lb Max Shear(V)=w*L/2 = 374 lb
