Roof
- Adaquate to support the additional imposed loads. No structural upgrades are required.
The following structural design regarding the proposed alterations have been prepared from these
assumptions. The verification of the field observations is the responsibility of the contractor. Prior to
commencement of work, the contractor shall verify the framing sizes, spacings, and spans noted in the
sealed plans, calculations, and/or certification letter and notify the Engineer of Record of any
discrepancies.
After review of the field observations and based on our calculations and in accordance with the
applicable building codes and current industry standards, the existing roof structure supporting the
proposed alterations consisting of the solar array has been determined to be:

The existing structure is assumed to have been designed and constructed following appropriate codes at the
time of erection and assumed to have appropriated permits. The calculations performed are only for the roof
framing supporting the solar array installation referenced in the stamped plans 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 observed during the
time the site observation are not included in this scope of work. All solar panel modules, racking, and
mounting equipment shall be designed and installed per the 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 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/or
certification letter and notify the Engineer of Record of any discrepancies prior to starting construction. If
during solar panel installation, the roof framing members appear unstable or deflect non-uniformly, our office
should be notified before proceeding with the installation. The contactor shall also verify that there are no
damage/deficiencies (i.e., dry rot, water damage, termite damage, framing member/connection damage, etc.) to
framing that was not addressed in the stamped plans, calculations, and/or certification letter and notify the
Engineer of Record of any concerns prior to starting construction.
Lucent Engineering, P.C.March 31, 2022
Should you have any questions regarding this letter or if you require further information, do not hesitate to
contact me.
Considering the existing roof's slope, size, spacing, condition, and calculated loads, the panel
bracket supports shall be placed no greater than 48 in. o/c.
Panel supports connections shall be staggered to distribute load to adjacent trusses.
Solar panels shall be designed, mounted, and installed in accordance with the most recent ''Ironridge
Manual'', which can be found on the Ironridge website (http://ironridge.com).
Based on the information supplied to us at the time of this report, on the evaluation of the existing structure, and
solar array panel bracket connection, it is our opinion that the roof system will adequately support the additional
loads imposed by the solar array. This evaluation conforms to 2018 IRC and current industry standards.

TEST PROCEDURE- PV10
DRAWN BY: SoloCAD
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
