Contractor : Wolf RIver Electric
Contractor Address : 101 Isanti Parkway NE, Isanti, MN 55040
Attn : To Whom It May Concern
A Field observation of the condition of the existing framing system was performed by an audit team from
Wolf RIver Electric. From the Field observation of the property, the existing roof structure observed as
follows:
Existing roof is supported by 2 x 4 @ 24" rafters at the solar array. The rafters are sloped at
approximately 34 degree and have maximum projected horizontal span of 7 feet in between
load bearing supports.
Design Criteria
Applicable codes: 2020 Minnesota Building Code (2018
IBC) ASCE 7-16
Ground Snow Load: 50 psf
Roof Dead Load: 20 psf
Wind speed: 125 mph
Risk Category: II
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 Design Criteria.

The following calculations are for the structural engineering design of the photovoltaic panels and are
valid only for the structural info referenced in the stamped plan set. The verification of such info is the
responsibility of others. After review, I certify that the roof structure has sufficient structural capacity for
the applied PV loads. All PV mounting equipment shall be designed and installed per manufacturer's
approved installation specifications.

The increase in weight as a result of the solar system is less than 10% of the existing structure and therefore no further
seismic analysis is required.
Limits of Scope of Work and Liability
Existing structure is assumed to have been designed and constructed following appropriate codes at
time of erection, and assumed to have appropriate permits. The calculations produced are only for the
roof framing supporting the proposed PV installation referenced in the stamped planset and were
completed according to generally recognized structural analysis standards and procedures, professional
engineering and design experience, opinions and judgements. Existing deficiencies which are unknown
or were not observable during time of inspection are not included in this scope of work. All PV modules,
racking, and mounting equipment shall be designed and installed per manufacturer's approved
installation specifications. The Engineer of Record and Engineerinc assume no responsibility for misuse
or improper installation. This analysis is not stamped for water leakage. Framing was determined based
on information in provided plans and/or photos, along with engineering judgement. Prior to
commencement of work, the contractor shall verify the framing sizes, spacings, and spans noted in the
stamped plans, calculations, and cert letter (where applicable) and notify the Engineer of Record of any
discrepancies prior to starting construction. Contractor shall also verify that there is no damaged framing
that was not addressed in stamped plans, calculations, and cert letter (where applicable) and notify the
Engineer of Record of any concerns prior to starting construction. Prior to the commencement of work,
the contractor shall verify the existing roof and framing conditions. Notify Engineerinc and the engineer of
record of any Discrepancies prior to starting construction. Prior to the commencement of work, the
contractor shall inspect framing for any damage such as water damage, cracked framing, etc. and notify
the E.O.R. if any issues are found.These plans/calculations are stamped for structural code compliance
of the roof framing supporting the proposed PV installation reference only. These plans/calculations are
not stamped for water leakage. PV modules, racking, and attachment components must follow
manufacturer guidelines and requirements.
