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)_________________ 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.

TOOLKIT DOCUMENT #5
Structural Criteria for Residential
Rooftop Solar Energy Installations
Your City
logo here
Use of this document
This toolkit document includes a one-page list of structural criteria for over-the-counter or online approval, as
well as attached tables and figures that supplement the criteria and explain their use.
This document applies to flush-mounted solar arrays installed on the roofs of wood-framed one- and two-
family dwellings. “Flush-mounted” means the modules are installed parallel to, and relatively close to, the roof
surface (see the “Solar Array Check” section of the Structural Criteria for specific qualifying requirements).
This list is intended to be a simple pre-installation check to gain reasonable assurance that the design of the
solar array complies with the structural provisions of the 2013 California Building Code (CBC) and 2013
California Residential Code (CRC). It is not intended to provide post-installation inspection criteria.
Currently Used Expedited Solar Permitting Approaches
This document is intended for jurisdictions without an expedited process for residential solar structural
permitting, and is not intended to replace or supplant procedures for jurisdictions with an expedited process
already in place. Good examples from jurisdictions with provisions for expedited structural permitting include
the City of Los Angeles, which exempts residential solar installations from structural permitting if five simple
requirements are met, and the East Bay Green Corridor’s streamlined solar permitting process, which uses
structural criteria tailored to typical conditions for that consortium of nine cities.
Regional and Site Assumptions
This document is based on the following regional and site assumptions:
• The dwelling is located in a ZERO snow load area (see Map 1).
• The dwelling is not in Wind Exposure D (within 200 yards of the ocean or a large coastal bay).
• If in Wind Exposure B (urban, suburban or wooded areas), the dwelling may be located:
– in a Special Wind Region (see Map 2) with design wind speeds between 110 and 130 mph, or
– on a tall hill, provided average slope is no steeper than 15%.
• If in Wind Exposure C (within 500 yards of large open fields or grasslands), the dwelling is:
– in a standard 110 mph design wind speed region, and
– not on a hill with a grade steeper than 5%.
Additional Options
The Chief Building Official (CBO) may consider adding rows to the structural criteria, based on personal
judgment and their jurisdiction’s conditions and history. Possible additional questions include:
• Regional and Site Checks
– If the jurisdiction is in a mixed snow load area, with zero snow load only at lower elevations, consider
asking “is the dwelling lower than elevation ___ feet?”
(Introductory text provided for jurisdiction’s reference only. Do not attach to Criteria that follow.)
2262 N Lyon St -
2017948205/30/23
– If the jurisdiction is in a coastal region, consider asking “is the dwelling farther than 200 yards from
the ocean or a large coastal bay?” to verify the dwelling is not in Wind Exposure D.
– If the jurisdiction is in a Special Wind Region with design wind speeds between 115 and 130 mph,
consider verifying that the dwelling is in Wind Exposure B by asking “is the dwelling in an urban,
suburban or wooded area, and not within 500 yards of open fields and grasslands?”
– If the jurisdiction is in a Special Wind Region with design wind speeds between 115 and 130 mph,
consider verifying that there are no significant topographic wind speed-up effects by asking “is the
dwelling in a relatively flat area (grade less than 5%) and not within 500 yards of the crest of a tall hill?”
• Roof Check
– Based on the jurisdiction’s one- and two-family housing stock and code compliance history, many
CBOs will find it reasonable to assume that most dwellings’ roof structures were designed to the
building code in effect at the time the houses were built. If so, the roof structure code compliance
check consists of the Contractor’s visual roof audit, checking for unusual sagging or deterioration,
without requiring additional measurements of existing rafters to check against span tables.
– For CBOs of jurisdictions with evidence of structurally deficient one- and two-family housing stock
or poor structural code compliance history, the CBO may elect to add the rafter span check option
described in the criteria.
The Structural Toolkit and CRC Wind Speeds
The 2013 CRC contains an inconsistency related to wind speeds. Despite referencing ASCE 7-10 as its
standard, the 2013 CRC’s text and tables use outdated ASCE 7-05 wind speeds. Under the old ASCE 7-05
/ CBC 2010, the basic design wind speed in most regions of the state was 85 mph (max. 3 second gust in
50 years). Under ASCE 7-10 / CBC 2013, the design wind speed has increased to 110 mph (max. 3 second
gust in 700 years). Despite the different definitions of wind speed, design wind pressures remain essentially
unchanged.
Because the Toolkit’s structural document is intended to be forward looking, all wind speeds in the Toolkit
document are based on the ASCE 7-10. This is clearly stated in the caption to the state wind speed map, and in
the Table 1 footnotes. This anticipates an obvious and expected correction to the CRC; otherwise the Toolkit
would become immediately outdated when the CRC is amended to change the base design wind speed from 85
mph to 110 mph.
2013 CRC text (ASCE 7-05) wind speeds equivalent to the 2013 CRC and CBC Reference Standard (ASCE
7-10) are shown below. See ASCE 7-10 Table C26.5-6 for additional information.
2013 CRC text 2013 CRC and CBC Referenced Standard

Structural Technical Appendix
This toolkit document is supported by a Structural Technical Appendix that describes the technical analysis
behind these criteria, which are based on structural engineering principles and the California Building
and Residential Codes. The Technical Appendix also provides some additional guidance to address non-
conforming items, such as when an anchor layout is not based on a solar support component manufacturer’s
guidelines, or when a coastal site is located within 200 yards of the ocean (Exposure D). This document can be
found online.
Probability of Code Compliance
The Structural Technical Appendix includes a section that examines the probabilities associated with the
assumptions behind Table 1 that allows six feet cross-slope anchor spacing in some circumstances. That
statistical analysis estimates that the probability of code noncompliance for six feet anchor spacing is only 2 in
a thousand installations (0.2%). Note that probability of structural failure is orders of magnitude lower than
the probability of code noncompliance.

The numbers in parentheses represent the upper elevation limits in feet for the ground snow load in psf listed
below the elevation. Example: (2400) ZERO in the South San Francisco bay area indicates that zero ground
snow loads occur from sea level up to an elevation of 2400 feet. CS indicates “Case Studies” where extreme
local variations in ground snow loads occur. Non-zero snow load areas and Case Study (CS) areas are excluded
from the use of this structural toolkit document. See the Technical Appendix for additional information.

Solar support component manufacturer’s guidelines may be relied upon to ensure the array above the roof is
properly designed, but manufacturer’s guidelines typically do NOT check to ensure that the roof itself can support
the concentrated loads from the solar array. Table 1 assumes that the roof complied with the building code in
effect at the time of construction, and places limits on anchor horizontal spacing to ensure that a roof structure is
not overloaded under either downward loads or wind uplift loads. Note 4 below lists the basic assumptions upon
which this table is based.
Table 1 Notes:
1. Anchors are also known as “stand-offs”, “feet”, “mounts” or “points of attachment”. Horizontal anchor
spacing is also known as “cross-slope” or “east-west” anchor spacing (see Figure 2).
2. If anchors are staggered from row-to-row going up the roof, the anchor spacing may be twice that shown
above, but no greater than 6’-0”.
3. For manufactured plated wood trusses at slopes of flat to 6:12, the horizontal anchor spacing shall not
exceed 4’-0” and anchors in adjacent rows shall be staggered.
4. This table is based on the following assumptions:
• The roof structure conformed to building code requirements at the time it was built.
• The attached list of criteria are met.
• Mean roof height is not greater than 40 feet.
• Roof sheathing is at least 7/16” thick oriented strand board or plywood. 1x skip sheathing is acceptable.
• If the dwelling is in Wind Exposure B (typical urban, suburban or wooded areas farther than 500
yards from large open fields), no more than one of the following conditions apply:
– The dwelling is located in a special wind region with design wind speed between 115 and 130
mph per ASCE 7-10, or
– The dwelling is located on the top half of a tall hill, provided average slope steeper is less than
15%.
• If the dwelling is In Wind Exposure C (within 500 yards of large open fields or grasslands), all of the
following conditions apply:
– Design wind speed is 110 mph or less (not in a Special Wind Region), and
– The dwelling is not located on the top half of a tall hill.
• The solar array displaces roof live loads (temporary construction loads) that the roof was originally
designed to carry.
• The Structural Technical Appendix provides additional information about analysis assumptions.

Beyond a visual review by the Contractor checking for unusual sagging or deterioration, some CBOs may want
additional assurance that the roof structure complies with structural building code requirements. Table 2 is an
optional table some CBOs may elect to use to provide additional assurance by requiring a check of existing roof
rafter spans, and supports optional criteria 1.B.5 and 1.B.6. For post-1960 construction, these span tables match
the rafter span tables found in the 2013 California Building and Residential codes. For pre-1960 construction, the
rafter span tables are based on structural calculations with lumber sizes and wood species & grade appropriate for
older construction. Note 5 below lists the basic assumptions upon which this table is based.
Table 2 Notes:
1. See Figure 4 for definition of roof rafter maximum horizontal span.
2. “Non-tile Roof” = asphalt shingle, wood shingle & wood shake, with an assumed roof assembly weight of
10 psf.
3. “Tile Roof” = clay tile or cement tile, with an assumed roof assembly weight of 20psf
4. Unaltered manufactured plated-wood trusses may be assumed to be code compliant and meet intent of
Table 2.
5. This table is based on the following assumptions:
• Span/deflection ratio is equal to or greater than 180.
• For post-1960 construction, wood species and grade is Douglas Fir-Larch No. 2.
• For pre-1960 construction, wood species and grade is Douglas Fir-Larch No. 1.
• Other wood species and/or grade are also acceptable if allowable bending stress is equal or greater to
that listed above.

Figure 1. Roof Visual Structural Review (Contractor’s Site Audit) of Existing Conditions.
The site auditor should verify the following:
1. No visually apparent disallowed rafter holes, notches and truss modifications as shown above.
2. No visually apparent structural decay or un-repaired fire damage.
3. Roof sag, measured in inches, is not more than the rafter or ridge beam length in feet divided by 20.
Rafters that fail the above criteria should not be used to support solar arrays unless they are first strengthened.
