Town of Estes Park
re: Structural Analysis 601 Summit Dr. Estes Park CO 80517
Dear Sir or Madam,
We have evaluated the solar racking and connections to the roof for the photovoltaic array to be installed using the
engineering design factors below.
ultimate wind speed V = 175 mph
wind exposure category = B
ground snow load = 66 psf
The PV system shall be flush mounted with no overhang. Attachments to the roof are to be spaced no more than 4’
O.C. Using the assumed engineering loads, we have determined that the design strength of all connections in the
solar racking system will be sufficient for this application.
The structural supporting members for the roof are 2x6” rafters 24” O.C. The roof framing has been evaluated using
the IEBC section 806.2. Since the solar array will weigh less than 3psf, it will not add more than 5% of existing
gravity loads and therefore is permitted under this section of code.
We do not assume responsibility for any construction flaws that currently exist or caused by other work trades.
Sincerely,
Anthony P. Boniface, PE
