To: Flex Energy Solar Re: Luis Olivarez
330 E 1750 N Building B 2514 S Olive St
Vineyard, UT 84058 Santa Ana, CA 92707
Flex Energy Solar proposes to install new roof-mounted solar panels at this residence and asked Right Angle
Engineering to review the existing structure for suitability. This letter summarizes the methods that were used to survey,
evaluate, and certify the existing roof framing and the attachment of the new solar panels to it. Pictures and calculations
are available on request.

Installation Instructions
Solar panels and the equipment shall be installed per the manufacturer's installation specifications. Improper installation
will void this certification. Deviations from the approved structural plans (including equipment substitutions) are not
allowed without written approval from Right Angle Engineering. Prior to installation, the installer should:
· Confirm that the existing structure matches the information provided in the structural survey, the approved
installation plans and this certification.
· Identify discrepancies between this certification and the approved installation plans. If found, then this
certification shall govern.
· Identify structural elements that are dangerous (cracked, broken, excessive sag, signs of overstress, rot,decay,
fire, water). If found, installation shall cease until those elements are adequately abated and made to comply with
the referenced building code.
· Provide fire setbacks and access pathways as required by local ordinances

STRUCTURAL CERTIFICATION
I certify the addition of solar panels on the roof of this structure does not cause the structure to become unsafe or make
it generally less compliant with the life-safety requirements of the referenced building code. Based on the evaluation
methods described below, for the loads that exist at this site, the existing framing should safely support the new solar
panels if they are installed and attached correctly. Electrical design is not included in this certification.
Array Name Certification Method Retrofits

Expedited Permit Process for PV Systems1
Expedited Permit Process for PV Systems
Standard String System
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 Standard String System to use with the Expe-
dited Permit Process. The Micro-Inverter, 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 Systems2
Expedited Permit Process for Small-Scale PV Systems
Standard String System
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.
