PFE Project#: 194267
On behalf of Valley Solar, Penn Fusion Engineering LLC (PFE) performed a structural analysis of the roof at the above
referenced location.The purpose of our analysis was to determine if the existing roof system is structurally sufficient to
support the new photovoltaic moudles in addition to the code required design loads.Our analysis is based on the information
provided by Valley Solar and is isolated only to the areas where the modules are intended to be placed.
System Specifications:
Total System Size: 4.2 kW/DC
Panel Specs: (12)LG Solar- LG350N1 C-A5
Inverter Specs: (12) Enphase - IQ7+
Racking System: SNAPNRACK- UR
The modules are to be located on the following roof plane:
Mounting Rafter Rafter Horizontal Collar Collar Tie Sheathing Shingle Number of Ceiling
Plane Size Spacing Span Ties Spacing Type Shingle Layers Profile
1 2x12 16" 9ft. 11 in. N/A 0" CDX 112" Asphalt 1 Flat
Shingles
The roof design has been analyzed in accordance with the 201 5 International Residential Code and Massachusettes
Amendments 9th Edition with design loads as follows:
Ground Snow(Pg): 40 psf
Wind Speed (V): 117 mph
Mounting Plane 1
The calculations for these structural members are attached. It has been determined by this office that the roof, as specified
above, is adequate to support the new PV modules in addition to the code required design loading.
Attach the module rail brackets to the roof with 5/16"lag bolts at 48 on center maximum with staggered penetration such
that load is distributed evenly among roof members. Provide a minimum of 2"of penetration into the wood members.
This office has determined that the installation of the PV System as specified above will meet the structural requirements of
the 2015 International Residential Code with Massachusettes Amendments 9th Edition and ASCE7-10 when installed in
accordance with the manufacture's instructions.
If you have any questions regarding this analysis, please feel free to contact us.
