Re: New PV System installation – Roche Residence
17542 5 Oaks Dr, Farmington, MN 55024
Dear Musa Keita:
Per your request, Linderman Engineering & Consulting (LEC) has completed an analysis and review of
the construction documents for the above referenced property. This review was completed for the
purpose of a proposed solar panel installation on the roof structure. Our observations and
recommendations are summarized below.
OBSERVATIONS
We received the following documents for the project:
• New PV System drawings: Dated 5/2/2022
The proposed equipment weights, layout information, and attachment details are included on the PV
system drawings for review.
The existing roof structure was observed by the installer to be pre-engineered wood trusses at 24”
spacing, as depicted on the PV System drawings.
RECOMMENDATIONS
In our professional opinion, we will offer the following recommendations:
The PV system is acceptable to be installed as proposed, and results in loads that are within the capacity
of the existing structure. We recommend that the proposed installation be approved for construction.
The proposed weights and configurations are well within the allowable roof design loads per Minnesota
Residential Code. The loads indicated are attached to roof framing and result in structural load paths
that will be uninterrupted and unaltered by the proposed installation.
We recommend that the attachment points all be located at truss top chord locations. If any attachment
locations are to occur between trusses, new 2x4 members should be framed between trusses to accept
the attachment. Do not attach panel brackets to roof deck only.
Thank you for the opportunity to assist with your engineering needs. If you have any questions or
comments, please feel free to contact me at:
