Expedited Permit Process for PV Systems
AC Module
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 AC Module to use with the Expedited Permit
Process. The Standard String, Micro-Inverter, 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 Systems2
Expedited Permit Process for Small-Scale PV Systems
AC Module
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.

Instructions: The licensed contractor of record shall complete all sections, answer the ten questions and
sign the certification section below. A copy of this form shall be attached to each of TWO sets of plans, of
minimum 11” x 17” size. If answering NO to any of the questions, plan check shall be required.
Project Address:
Contractor Company Name:
Contractor License Number:
YES NO Are the following applicable to the proposed project?
1. Will the PV system layout provide the required three-foot wide clear access pathways
per Section 605.11 of the California Fire Code, and is this shown on the roof plan?
2. Will the PV system be installed on a roof having only one roofing layer with no
overlays?

modules (panels) are parallel to the plane of the roof?
4. Will the PV system weigh maximum 4 pounds per square feet or less?
5. Will the PV system be installed where the modules do not overhang any roof edges
(such as eaves, gabled ends, ridges and hips)?
6. Will the PV system be installed with a space of 2” minimum to 10” maximum between
the underside of modules and the surface of the roof?
7. Will the PV system be installed without using any ballast system or counter-weight
system?

To Whom It May Concern
This letter is to certify that we have performed a structural analysis of the existing roof members that are to
support photovoltaic panels, as shown on the attached report. The calculations were performed in accordance
with the latest editions of IBC, NDS, ASCE/SEI, CBC, and IRC, and the latest edition of the building codes
for the state of California.
Our analysis was based on the following design criteria:
Ground Snow (psf)0 psf
Sloped Snow (psf), reduced per ASCE, Sect. 7.4 0 psf
Basic Wind Speed (mph):110 mph
Roof Slope:20 degrees
The PV module orientation:Landscape
The maximum horizontal roof mount spacing:6 ft.
The maximum vertical roof mount spacing:1.708 ft.
Staggered roof mounts required?Yes
Based on this analysis, we can certify that the individual existing roof framing members that support the
PV panels; and the individual roof members as described in the attached report; are adequate to support the
design loads as required by the various codes. This includes Dead Loads (including the weight of the PV
panels), Live Loads, Snow Loads, and Wind Loads, on the roof members that support the PV panels,
combined as required in the codes.
If you have any questions on this or need further clarification,
please contact us at your convenience.
Sincerely,
Paul Truong, P.E.
NOTE:
1. Prior to commencement of work, the Solar Installer shall verify
that the roof framing sizes, spacing, and spans (between supports),
are as noted in these plans. The Engineer of Record must be
notified if any discrepancies are discovered, before proceeding.
2. These plans are Stamped for Structural Code compliance of
the roof members that support the PV solar system only.
3. These plans are not stamped for rain water leakage prevention.
4. As a precaution, old or wet snow should be removed from the roof,
if the snow builds up to 18" or more.
