To Whom It May Concern
This letter is to certify that we have performed a structural analysis of the existing roof members that are to
support photovoltaic panels, as shown on the attached report. The calculations were performed in accordance
with the latest editions of IBC, NDS, ASCE/SEI, CBC, and IRC, and the latest edition of the building codes
for the state of Idaho.
Our analysis was based on the following design criteria:
Ground Snow (psf) 50 psf
Sloped Snow (psf), reduced per ASCE, Sect. 7.4 47.55 psf
Basic Wind Speed (mph): 115 mph
Roof Slope: 18 degrees
The PV module orientation: Landscape
The maximum horizontal roof mount spacing:2 ft.
The maximum vertical roof mount spacing: 3.417 ft.
Staggered roof mounts required? No
Based on this analysis, we can certify that the individual existing roof framing members that support the
PV panels; and the individual roof members as described in the attached report; are adequate to support the
design loads as required by the various codes. This includes Dead Loads (including the weight of the PV
panels), Live Loads, Snow Loads, and Wind Loads, on the roof members that support the PV panels,
combined as required in the codes.
If you have any questions on this or need further clarification,
please contact us at your convenience.
Sincerely,
Paul Truong, P.E.
NOTE:
1. Prior to commencement of work, the Solar Installer shall verify
that the roof framing sizes, spacing, and spans (between supports),
are as noted in these plans. The Engineer of Record must be
notified if any discrepancies are discovered, before proceeding.
2. These plans are Stamped for Structural Code compliance of
the roof members that support the PV solar system only.
3. These plans are not stamped for rain water leakage prevention.
4. As a precaution, old or wet snow should be removed from the roof,
if the snow builds up to 18" or more.
Phong Truong, P.E.
