Roof-Mounted Solar PV Systems
(Residential & Commercial)
Ground-Mounted Solar PV Systems
(Residential & Commercial)
Building Permit
Electrical Permit
Structural Compliance:* Construction plan, specication
sheets, photos, and installation manuals for all manufactured
components (see Appendix 1). Additional information as
requested by Inspector.
Site plan showing location of major components on the
property and a framing cross-section that identies type
of support (rafter or truss), spacing, span dimension, and
approximate roof slope (see Appendix 2).
Building Permit
Electrical Permit
Structural Compliance: Construction plan, specication
sheets, photos, and installation manuals for all manufactured
components (see Appendix 1). Additional information as
requested by Inspector.
Site plan showing location of major components on the
property, setbacks, elevations, size (see Appendix 2).
* The MN Department of Labor and Industry (DLI) and Minnesota Department of Commerce developed a Solar PV standardized structural load table for
residential structures to help determine if the roof structure of wood-framed buildings is sucient to handle the additional weight of solar PV systems.
Permit applicants may use the standardized load table report in conjunction with manufacturer installation recommendations to demonstrate
structural compliance.
Building Permit Fees (see Building Permit Fee Schedule)
Please allow 5-10 business days for issuance of the permit. This process may be delayed if the plans are incomplete. You will be
notied when your permit is ready to be picked up and paid for.
Appendix 1. Structural Review Of PV Installation Mounting System & Roof
1. Is the roof supporting the installation a pitched roof in good condition, without visible sag or deection, no cracking or
splintering of support, or other potential structural defect? Yes No
2. Is the roof a rafter system?* Yes No
* For truss systems, additional information may be needed to establish the truss’ design loads. The SolarStruc Tool (www.growsolar.org) allows
contractors to calculate truss capacity for solar installations. Contact the building ocial for standards on when structural analysis will be needed.
3. Is the equipment to be ush-mounted to the roof such that the collector surface is parallel to the roof? Yes No
4. Is the roong type lightweight?
(composition, lightweight masonry, metal, etc) Yes No
5. Does the roof have a single layer covering? Yes No
If “No” to any of questions 1–4 above, additional documentation may be required. Documentation may need to demonstrate the structural integrity
of the roof and all necessary structural modications needed to maintain integrity. A statement stamped by a Minnesota licensed/certied structural
engineer certifying integrity may be needed. Contact the building ocial to determine submittal requirements.
6. Identify method and types of weatherproong for roof penetrations (eg, ashing, caulk):
7. Is the mounting structure an engineered product designed for PV modules with no more than an 18” gap beneath the module
frames?
Yes No (If “No” provide details of structural attachment certied by a design professional. Manufacturer’s engineering specications are
sucient to meet this requirement.)

8. For manufactured mounting systems, complete information below.**
a. Mounting system manufacturer: ___________________________________________________________________________
b. Product name and model number: _________________________________________________________________________
c. Total weight of PV modules and rails: ______________ lbs
d. Total number of attachment points: ____________ (attachment points must be equally distributed across the array)
e. Weight per attachment point (c÷d): ______________ lbs
f. Maximum spacing between attachment points on a rail: ______________ inches
(See product manual for maximum spacing allowed based on maximum design wind speed.)
g. Total surface area of PV modules: _________________ square feet
h. Distributed weight of PV module on roof (c÷g): _______________ lbs/square feet
If the outcome of e. is greater than 45 lbs or h. is greater than 5 lbs/ft2, a study or statement demonstrating the structural integrity of the
installation, or a statement stamped by a Minnesota licensed/certied structural engineer, may be required. Contact the building ocial to
determine requirements.
** Attaching the rail to each rafter or truss that passes under the array, or to blocking installed between each support, may serve to mitigate for any
structural uncertainties on older roofs or wind loading concerns. This approach was used by Minneapolis and St Paul based on engineering studies
conducted with their building stock. Contact the building ocial to determine requirements.
