Expedited Permit Process for PV Systems - Micro-Inverter1
Expedited Permit Process for PV Systems
Micro-Inverter
The Solar America Board for Codes and Standards (Solar ABCs) Expedited Permit Pro-
cess provides a means to differentiate systems that can be permitted quickly and easily
due to their similarity with the majority of small-scale PV systems. Those systems with
unique characteristics may be handled with small additions to this Expedited Permit
Process or may require much more information, depending on the uniqueness of the
installation.
The following pages contain forms for the Micro-Inverter to use with the Expedited Per-
mit Process. The Standard String, AC Module, and Supply-Side Connection forms
are also available as interactive PDF files at www.solarabcs.org/permitting. In jurisdic-
tions that have adopted the Expedited Permit Process for PV Systems, these forms can
be filled out electronically and submitted in either printed form and via email. An elec-
tronic format is used so that the supplied information is standardized and legible for the
local jurisdiction.

Expedited Permit Process for PV Systems — Micro-Inverter2
Expedited Permit Process for Small-Scale PV Systems
Micro-Inverter
The information in this guideline is intended to help local jurisdictions and contractors identify when PV system installations
are simple, needing only a basic review, and when an installation is more complex. It is likely that 50%-75% of all residential
systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolution steps have been
suggested to provide as a path to permit approval.
Required Information for Permit:
1. Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it
should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings
with a 3’ perimeter space at ridge and sides may not need separate fire service review.
2. Electrical diagram showing PV array configuration, wiring system, overcurrent protection, inverter, disconnects,
required signs, and ac connection to building (see supplied standard electrical diagram).
3. Specification sheets and installation manuals (if available) for all manufactured components including, but not
limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system.
Step 1: Structural Review of PV Array Mounting System
Is the array to be mounted on a defined, permitted roof structure? l Yes l No
If No due to non-compliant roof or a ground mount, submit completed worksheet for the structure WKS1.
Roof Information:
1. Is the roofing type lightweight (Yes = composition, lightweight masonry, metal, etc…)__________________________
____________________________________________________________________________________________________
If No, submit completed worksheet for roof structure WKS1 (No = heavy masonry, slate, etc…).
2. Does the roof have a single roof covering? l Yes l No
If No, submit completed worksheet for roof structure WKS1.
3. Provide method and type of weatherproofing roof penetrations (e.g. flashing, caulk).____________________________
Mounting System Information:
1. Is the mounting structure an engineered product designed to mount PV modules with no more than an 18” gap
beneath the module frames? l Yes l No
If No, provide details of structural attachment certified by a design professional.
2. For manufactured mounting systems, fill out information on the mounting system below:
a. Mounting System Manufacturer ___________Product Name and Model#________________________________
b. Total Weight of PV Modules and Rails ___________lbs
c. Total Number of Attachment Points____________
d. Weight per Attachment Point (b÷c)_________________lbs (if greater than 45 lbs, see WKS1)
e. Maximum Spacing Between Attachment Points on a Rail ______________inches (see product manual for
maximum spacing allowed based on maximum design wind speed)
f. Total Surface Area of PV Modules (square feet)_________________ ft2
g. Distributed Weight of PV Module on Roof (b÷f)_______________ lbs/ft2
If distributed weight of the PV system is greater than 5 lbs/ft2, see WKS1.
Step 2: Electrical Review of PV System (Calculations for Electrical Diagram)
In order for a PV system to be considered for an expedited permit process, the following must apply:
1. PV modules, utility-interactive inverters, and combiner boxes are identified for use in PV systems.
2. The PV array is composed of 4 series strings or less per inverter.
3. The total inverter capacity has a continuous ac power output 13,440 Watts or less
4. The ac interconnection point is on the load side of service disconnecting means (690.64(B)).
5. One of the standard electrical diagrams (E1.1, E1.1a, E1.1b, or E1.1c) can be used to accurately represent the PV
system. Interactive PDF diagrams are available at www.solarabcs.org/permitting.
Fill out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the applicant
understand each blank to fill in. If the electrical system is more complex than the standard electrical diagram can effectively
communicate, provide an alternative diagram with appropriate detail.

Solar Array Installation
To Whom It May Concern:
We have reviewed the existing structure at the above referenced site. The purpose of our review was to determine the
adequacy of the existing structure to support the proposed installation of solar panels on the roof as shown on the panel
layout plan.
Based upon our review, we conclude that the existing structure is adequate to support the proposed solar panel installation.
Design Parameters
Code: California Residential Code, 2022 Edition (2021 IRC)
Risk Category: II
Design wind speed, Vult: 96 mph (3-sec gust)
Wind exposure category: C
Seismic design category: D
Connection to Roof
Mounting connection: (1) 5/16" lag screw w/ min. 2.5" threaded embedment into framing at max. 72" o.c. along rails
Install (2) rails per row of panels, evenly spaced; panel length perpendicular to the rails shall not exceed 71.7 in
Rail cantilever shall not exceed the lesser of 50% of the connection spacing or maximum cantilever allowed by
manufacturer
Connections shall be staggered so as not to overload any existing structural member
Conclusions
Based upon our review, we conclude that the existing structure is adequate to support the proposed solar panel installation.
In the area of the solar array, other live loads will not be present or will be greatly reduced (2022 CRC, Section R324.4.1.1).
The gravity loads, and thus the stresses of the structural elements, in the area of the solar array are either decreased or
increased by no more than 5%. Therefore, the requirements of Section 503.3 of the 2022 CEBC are met and the structure is
permitted to remain unaltered.

The solar array will be flush-mounted (no more than 10" above the roof surface) and parallel to the roof surface. Thus, we
conclude that any additional wind loading on the structure related to the addition of the proposed solar array is negligible.
The attached calculations verify the capacity of the connections of the solar array to the existing roof against wind (uplift),
the governing load case. Regarding seismic loads, we conclude that any additional forces will be small. Conservatively
neglecting the weight of existing wall materials, the installation of the solar panels represents an increase in the total weight
(and resulting seismic load) of 1.6%. Increases in lateral forces less than 10% are considered acceptable. Thus the existing
lateral force resisting system is permitted to remain unaltered.
Limitations
Installation of the solar panels must be performed in accordance with manufacturer recommendations. All work performed
must be in accordance with accepted industry-wide methods and applicable safety standards. The contractor must notify
Vector Structural Engineering, LLC should any damage, deterioration or discrepancies between the as-built condition of the
structure and the condition described in this letter be found. The use of solar panel support span tables provided by others is
allowed only where the building type, site conditions, site-specific design parameters, and solar panel configuration match
the description of the span tables. The design of the solar panels, solar racking (mounts, rails, etc.) and electrical engineering
is the responsibility of others. Waterproofing around the roof penetrations is the responsibility of others. Vector Structural
Engineering assumes no responsibility for improper installation of the solar array. Vector Structural Engineering shall be
notified of any changes from the approved layout prior to installation.

Design Responsibility:
The U-Builder 2.0 design software is intended to be used under the responsible charge of a registered design professional where
required by the authority having jurisdiction. In all cases, this U-Builder 2.0 software should be used under the direction of a
design professional with sufficient structural engineering knowledge and experience to be able to:
• Evaluate whether the U-Builder 2.0 Software is applicable to the project, and
• Understand and determine the appropriate values for all input parameters of the U-Builder 2.0 software.
This letter certifies that the Unirac SM SOLARMOUNT Rails Flush, when installed according to the U-Builder 2.0 engineering
report and the manufacturer specifications are in compliance with the above codes and loading criteria.
This certification excludes evaluation of the following components:
1) The structure to support the loads imposed on the building by the array; including, but not limited to: strength and
deflection of structural framing members, fastening and/or strength of roofing materials, and/or the effects of snow
accumulation on the structure.
2) The attachment of the SM SOLARMOUNT Rails to the existing structure.
3) The capacity of the solar module frame to resist the loads.
This requires additional knowledge of the building and is outside the scope of the certification of this racking system.
Please feel free to call for any questions or clarifications.
