After review of the field observation report and based on our structural capacity calculations in accordance
with applicable building codes, the existing roof framing supporting the proposed solar panel layout has been
determined to be:
adequate to support the imposed loads. Therefore, no structural upgrades are required.
4/20/2022
A field observation was performed to document the existing framing of the above mentioned address. From
the field observation, the existing roof structure was observed as:
Shingle roofing supported by 2x4 Truss @ 24 in. OC spacing. The roof is sloped at approximately 33
degrees and has a max beam span of 8 ft between supports.

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 mounting equipment shall be designed and installed per manufacturer's approved installation
specifications.

Total Additional PV Weight (lbs) =
(Existing W + Additional W)/(Existing W) =104%
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 the engineering consulting firm 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.

TEST PROCEDURE
Contact Info and General
1. Name of Customer who owns service, the Xcel Energy “customer of record” for existing services
2. Installation premise address shall match application address
2.1 Address shall match the premise address for existing customer/services
3. Application OID, SRC, or case number assigned to the project
4. A note stating “All testing shall be performed by qualified personnel"
Testing Applicable to all DER
5. The procedure shall provide steps to verify fixed power factor settings for each inverter meet the
project requirements
6. The unintentional islanding test shall at minimum contain the following steps:
6.1 Steps that verify DER system is ready to be energized
6.2 Steps to verify labeling for the Main Service Panel, DER Protection, DC Disconnect, AC disconnect, Utility AC disconnect, Production Meter (when
applicable) and other relevant labelling and signage
6.3 Steps to energize the DER system
6.4 While in normal operation, steps to verify the voltages at the DER AC terminals are within 5% of the combined DER AC voltage ratings and all LEDs,
alarms, and/or LCD codes are “normal”
6.5 While in normal operation, steps to verify that all DER units are operational and producing power
6.6 Steps to simulate the loss of utility source11 for the unintentional islanding test shall be listed
6.6.1 Clearly identify the disconnection device being used to simulate this utility power outage
6.7 Using a voltmeter, verify the voltage at the inverter side of the AC disconnect has dropped to zero
6.7.1 Only customer-owned equipment shall be used for this verification. Xcel Energy will not provide special equipment for this verification. Xcel
` Energy provided meters shall not be used for this verification.
6.8 Using an ammeter or the DER’s display/metering, verify the DER has ceased to energize within two seconds. For three phase systems, three phase
monitoring may be required.
7. Verify DER LEDs, alarms, and/or LCD codes are appropriate for loss of Utility source
8. Steps to restore the lost Utility source shall be listed
9. A step to verify that the inverter system delays five (5) minutes before resuming power output after the Utility source is restored shall be listed
