Client: Javemick-2001933 ss/oNAL '
Address: 12 Rockdale Ave, Salem, MA 01970
Arm.: To Whom It May Concern,
A field observation of the condition of the existing framing system was performed by an audit team from Sungevity.
From the field observation of the property, the existing roof structure was observed as follows:
The existing roof structure consists of composition shingles over plywood sheathing that is supported by 2x4 roof trusses
at 24" on center at Arrays 1 &2. The rafters at all arrays are sloped at approximately 21 degrees and have a maximum
projected horizontal span of 6'-3" at Array 1 and 6'-5" at Array 2 between load bearing supports.
All attached structural calculations are based on these observations and the design criteria listed below:
Design Criteria:
• Applicable Codes= 2009 IBC, ASCE 7-05 and 2005 NDS
• Ground Snow Load =45 psf
• Roof Dead Load— 7.5 psf(All Arrays)
• Basic Wind Speed= 110 mph Exposure Category C
• Solar modules=as indicated in attached drawings.
As a result of the completed field observation and design checks:
• Arrays 1 &2 are adequate to support the loading imposed by the installation of
solar panels and modules. Therefore, no structural upgrades are required.
I certify that the capacity of the structural roof framing that directly supports the additional gravity loading due to the solar
panel supports and modules had been reviewed and determined to meet or exceed the requirements in accordance with the
2009 IBC.
If you have any questions on the above, do not hesitate to call.

The following calculations are for the Structural Engineering Design of the Photovoltaic Panels
located at 12 Rockdale Ave, Salem, MA 01970. After review, PZSE, Inc. certifies
that the roof structure has sufficient structural capacity for the applied PV loads.
