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)_________________ ft 2
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.

Roof structural framing plan has been reviewed for additional loading due to installation of the roof mounted
solar PV addition. The structural review that follows, including plans and calculations, only apply to the section
of the roof that is directly supporting the solar PV system and its supporting elements.
17 January 2023
Per your request, 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 per layout plan.
820 N Euclid St
03/27/23
OBSERVED CONDITIONS:
CONCLUSIONS:
LIMITATIONS:
Praneet R Erusu, P.E.
Principal Engineer
Erusu Consultants US Inc.
The observed roof framing is described below. If field conditions differ, the contractor shall notify the engineer
prior to starting construction. The roof framing is supported by 2x8 Rafters @ 18" O.C are spanning between
load bearing walls. The maximum allowed clear span of rafter is 16.5ft, to be verified in field by the contractor.
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
CBC, Section 1607.14.4). The gravity loads and 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 6" 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 2.1%. Because the
increase in lateral forces is less than 10%, this addition meets the requirements of the exception in Section
503.4 of the 2022 CEBC. Thus the existing lateral force resisting system is permitted to remain unaltered.
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.
Existing Roof and structural members are assumed to be in good and serviceable condition. The contractor
must notify Erusu Consultants US Inc. 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 are 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
panel racking (mounts, rails, etc.) and electrical engineering is the responsibility of others. Waterproofing
around the roof penetrations is the responsibility of others. Erusu Consultants US Inc. assumes no
responsibility for improper installation of the solar array.
