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.July 17, 2023
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 24 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 ''Quick
Mount PV Manual'', which can be found on the QuickMountPV website (http://quickmountpv.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 2020 MNRC and current industry
standards.

Tech Brief:PTWSPÄLK.YV\UKPUNMVY,]LY`(WWSPJH[PVUThe UFO family of components eliminates the need for separate grounding hardware by bonding solar modules directly to IronRidge XR Rails. All system types that feature the UFO family—Flush Mount, Tilt Mount and Ground Mount—are fully listed to the UL 2703 standard.UFO hardware forms secure electrical bonds with both the module and the rail, resulting in many parallel grounding paths throughout the system.
