Re: Engineering Services Vaughan Residence 19763 Idealic Avenue, Lakeville, MN 10.412 kW System
To Whom It May Concern:
Pursuant to your request, we have reviewed the following information regarding solar panel installation on the roof of the above referenced home:
1. Site Visit/Verification Form prepared by an Everlight Solar representative identifying specific site information including size and spacing of rafters for the existing roof structure. 2. Design drawings of the proposed system including a site plan, roof plan and connection details for the solar panels. This information was prepared by Everlight Solar and will be
utilized for approval and construction of the proposed system. 3. Photographs of the interior and exterior of the roof system identifying existing structural members and their conditions.
Based on the above information we have evaluated the structural capacity of the existing roof system to support the additional loads imposed by the solar panels and have the following comments related to our review and evaluation:
Description of Residence: The existing residence is typical wood framing construction with the roof system consisting of truss system
with all chords constructed of 2 x 4 dimensional lumber at 24” on center. The attic space is unfinished and photos indicate that there was free access to visually inspect the size and condition of the roof rafters. All wood material utilized for the roof system is assumed to be Doug-Fir #2 or better with standard construction components. The existing roofing material consists of composite asphalt shingles. Photos of the dwelling
also indicate that there is a permanent foundation. A. Loading Criteria Used • 115 MPH wind loading based on ASCE 7-16 Exposure Category “C” at a slope of 25 degrees
• 7 PSF = Dead Load roofing/framing Live Load = 20 PSF Snow Load = 50 PSF
• 3 PSF = Dead Load solar panels/mounting hardware
Total Dead Load =10 PSF
The above values are within acceptable limits of recognized industry standards for similar
structures in accordance with the Minnesota Residential Code (2018 IRC). Analysis performed of the existing roof structure utilizing the above loading criteria indicates that the existing rafters will support the additional panel loading without damage, if installed correctly.

B. Solar Panel Anchorage
1. The solar panels shall be mounted in accordance with the most recent “IronRidge Solar Installation Manual”, which can be found on the IronRidge Solar website (http://ironridgesolar.com/). 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.
2. Maximum allowable pullout per lag screw is 235 lbs/inch of penetration as identified in the National Design Standards (NDS) of timber construction specifications for Doug-Fir (North Lumber) assumed. Based on our evaluation, the pullout value, utilizing a penetration depth of 2 ½”, is less than what is allowable per connection and therefore is adequate. Based on the variable factors for
the existing roof framing and installation tolerances, using a thread depth of 2 ½” with a minimum size of 5/16” lag screw per attachment point for panel anchor mounts should be adequate with a sufficient factor of safety. 3. Considering the roof slopes, the size, spacing, condition of roof, the panel supports shall be placed
no greater than 48” o/c. 4. Panel supports connections shall be staggered to distribute load to adjacent trusses. Based on the above evaluation, it is the opinion of this office that with appropriate panel anchors being utilized
the roof system will adequately support the additional loading imposed by the solar panels. This evaluation is in conformance with the Minnesota Residential Code (2018 IRC), current industry standards, and is based on information supplied to us at the time of this report.
Should you have any questions regarding the above or if you require further information do not hesitate to contact me.
Very truly yours, Scott E. Wyssling, PE Minnesota License No. 57927

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
