Re: Review of Design Load Testing and Rating
WJE No. 2011.0096
To whom it may concern:
At the request of Silicon Energy, Wiss, Janney, Elstner Associates, Inc. (WJE) has reviewed the
mechanical load test results reported by Intertek, an Occupational Safety Health Administration
(OSHA) Nationally Recognized Testing Laboratory (NRTL), for the Cascade PV Module assembly
including the module and mounting system manufactured by Silicon Energy. The Cascade PV Module
assembly is described in Cascade PV Module Manual Revision 3, and the Cascade System Installation
Guide Revision 2. The PV Module assembly is approximately 51 -3/4 inches wide by 47 -1/2 inches long
and consists of two layers of 1/8 inch thick tempered glass laminated together and attached to an 1/8 inch
thick aluminum frame mounting foot. Silicon Energy has asked that we review the relevant mechanical
load test results and report our findings in this letter.
We have reviewed the relevant portions of the Intertek test report titled Listing Constructional Data
Report issued June 23, 2009, and revised August 3, 2010. Load testing was conducted by Intertek in
accordance with the test standard Flat -Plate Photovoltaic Modules and Panels UL 1703 dated March 15,
2002 (UL 1703) Section 41 Mechanical Loading Test. According to the test report, the design load for the
Cascade PV Module assembly confirmed by the testing is 125 pounds per square foot (psf). The Silicon
Energy PV Models covered by the test report include the following: SiE -150, SiE -155, SiE -160, SiE -165,
SiE -170, SiE -175, SiE -180, SiE -185, SiE -190, SiE -195, and SiE -200. It is reported that these models are
identical in every construction detail, and differ only in cell efficiency and electrical rating.

This manual contains important safety, installation, operation, service, and
maintenance information that you should understand in its entirety prior to
installing, wiring, or using Silicon Energy PV modules.
Do not connect or disconnect modules under load.
Silicon Energy PV modules are designed to produce direct current (DC)
electricity from light. Modules wired in series, parallel, or series parallel
configurations can produce electrical shock great enough to cause damage to
property, injury, or death by electrocution.
Prior to installing, wiring, or using Silicon Energy PV modules you should:
fully understand and practice electrical, building, and fire safety
fully understand PV /solar electric systems
have knowledge of, experience with, and follow all local and national building and
electrical codes (see National Electric Code -NEC Article 690)
Product Handling
Only knowledgeable and trained professionals should install these modules.
In some jurisdictions, licensed contractors may be required for installation.
Multiple panels connected in series can produce high voltages which are potentially hazardous.
Do not wire the modules during wet, damp or high wind conditions.
Cascade PV modules are constructed with a tempered glass front and back. Although durable, it is glass. Handle with care.
Do not set the module down in such a way that the exposed edges of glass are supporting any weight.
Areas on the module most prone to damage are the exposed edges of glass and the leads. Pay particularly close attention to
protecting these areas from damage while installing, servicing, or maintaining the module(s).
Do not stand on, step on, or kneel on the module.
Do not drop the module, drop objects onto the module, or set heavy loads on the module.
Avoid any sharp impacts between objects and the module.
Always treat the output wires of the modules as a potential source of electricity and electrical shock.
Photovoltaic modules do not have to be connected to a circuit to generate DC current.
Each installer should wear safety gear including eye, head, hand and fall protection.
The modules are heavy and must be handled properly to avoid injury to persons and damage to product. It is recommended
that two people lift and move modules due to their size and weight.
Protect person and module from falls when installing above ground.
Inspect modules for damage, particularly to the leads. Never install a damaged module. Use extreme caution when
handling a module with a damaged lead.
PLEASE NOTE, AS PER SECTION 48, UL 1703:
PV module power is affected by both temperature and light:
Colder temperatures can increase the voltage and power.
Reflection of light from snow, water, or other surfaces can increase the current and power.
Do not artificially concentrate light on the module(s).
Under normal conditions, a PV module is likely to experience conditions that produce more current and/or voltage than
reported at standard test conditions (STC). Accordingly, the values of I and V marked on this module should be
multiplied by a factor of 1.25 when determining component voltage ratings, conductor ampacities, fuse sizes, and size of
controls connected to the PV for output.
Refer to Section 690 of the National Electric Code (NEC 690.8) for another additional multiplying factor of 1.25 (80%
derating) which may be applicable.
The electrical characteristics are within -10% of the indicated values of I V and Pmax under standard test conditions
(irradiance of 100 mW /cm AM 1.5 spectrum, and a cell temperature of 25 °C 77 °F)

www.Silicon Energy.com Cascade PV Module Manual Rev. 3
1. Compliance
Silicon Energy's Cascade PV Modules are built to comply with UL 1703, "Flat -Plate Photovoltaic Modules and Panels
These modules contain no user serviceable parts. Please read the following warning statements before installing the
modules:
The installer is responsible for following all local and national building and electrical codes, including those
which may supersede specifications contained in Silicon Energy manuals.
Consult local building authority for all wind, snow and seismic requirements. Some jurisdictions may require an
engineering certification.
The installer is responsible for ensuring the following:
the building /mounting structure can support all code required loading conditions
waterproof integrity of the mounting surface; including the use of appropriate flashing when needed
Silicon Energy Cascade Modules are appropriate for the specific installation environment and site conditions.
Substitution of fasteners and wire connectors other than those supplied by Silicon Energy may void warranty.
Use a minimum of 14 AWG USE -2 sunlight- resistant wire or PV wire and Tyco SOLARLOK Connectors for all
wiring connections.
Ground module(s) according to the instructions in the Grounding Requirements Section.
Provide 15 amp max series fuse rating over current protection.
This module carries a Class A fire rating. In order to maintain this rating, when mounted on a roof structure, the
module must be mounted as specified, maintaining a minimum clearance of 1.5 inches. The roof surface must be
made up of a fire resistant covering appropriate for the application and abiding by local authority guidelines.
2. Module Specifications
The Cascade PV Module currently comes in one physical configuration (see Figure 1) with a series of electrical
specifications (see Table 1). See the Silicon Energy Cascade Installation Guide for dimensions of the module when
mounted with the custom Cascade Installation System.
Referencing the component callouts in Figure 1, each module is comprised of:
1. 49 crystalline silicon cells and 6 diodes encapsulated in one high- strength, double -glass lamination.
2. An aluminum edge guard/ side frame is factory mounted along each of two sides of the module.
3. Each edge guard has two 1 4-20 Mounting Studs with two' /a -20 serrated flange nuts and
4. Each edge guard has one 1 4-20 Grounding Stud with one' /a -20 serrated flange nut.
5. A negative lead made up of 14 AWG USE -2 wire and exiting the module from a strain- relieved, sealed
compartment.
6. A positive lead made up of 14 AWG USE -2 wire and exiting the module from a strain relieved, sealed
compartment.
7. The negative lead is terminated with a Tyco SOLARLOK Connector (male housing).

3. Module Installation
The following general instructions are provided as the minimum required for safety. For detailed mounting instructions
see the Silicon Energy Cascade System Installation Guide.
3.1. Electrical Installation Safety
Solar modules and their interconnection cables pass direct current (DC) and can be a
voltage source when exposed to light or under load. DC can arc across gaps and may
cause injury or death if wiring is connected or disconnected when current is present.
Modules must never be connected or disconnected under load. Before (dis)connecting modules, the
circuit must be broken at another point using a rated device intended for that purpose (e.g. breaker).
A short circuited module or array exposed to light will produce current that should be treated as a load.
Fully cover all modules with an opaque material before connecting or disconnecting modules.
3.2. Electrical Installation Requirements
All installations must comply with the National Electric Code (NEC) and all applicable local codes.
Provide 15 amp maximum series fuse rating for over current protection.
Secure all wires and protect from mechanical damage.
For all installer supplied wiring, use a minimum USE -2 sunlight- resistant wire or PV wire with a maximum
conductor temperature of at least 90C (wet) such as found in the Table 2.

The module output leads are 14 AWG and come with factory installed connectors (see Table 3).
When making the final connection of the array to the positive and negative disconnects, use only UL
recognized solar connectors such as Tyco SOLARLOK connectors. The metallic crimp supplied within the
connector may only be applied using the approved Tyco crimping tool.

3.3. Grounding Requirements
This module does not have a continuous frame. Therefore, for safety and to protect the system from
lightning, both edge guards of the module must be grounded. Connect to earth ground using the center PEM
studs and the flange nuts provided.
When the module is properly installed with Silicon Energy's Cascade Installation System, the module will
be grounded to the installation structure and no additional grounding of the module will be necessary.
The ground conductors must be a minimum of 6AWG if installed in such a way that it is exposed to
mechanical damage. Ground conductors which are protected from mechanical damage must be a minimum
of 14AWG.
3.4. Mechanical Installation Requirements
Modules must be fastened securely to installation systems intended for PV applications.
Wind and snow loads not to exceed 125 psf.
For module applications requiring greater strength Silicon Energy must be consulted to protect the module
warranty and an engineer must be used to design the installation means.
Engineering verification is recommended to ensure a structurally sound roof or mounting structure.
When roof mounted, module and installation system must be over a fire resistant roof covering rated for the
application.
The Cascade PV Modules must be mounted with edge guards parallel to the fall line of the roof or mounting
structure. They are designed to be rotated to have the positive lead on either side, but must not be mounted
with the edge guards running perpendicular to the fall line.
As always, good practice should be used when installing Silicon Energy Cascade PV Modules:
Mount to maximize solar exposure and minimize or eliminate shading.
Modules may be mounted at any angle from 0 to 90 however the Cascade Installation System does
have minimum installation angles. See the Silicon Energy Cascade System Installation Guide for more
details.
When installing these modules the following should be considered:
Avoid low angle installations to prevent buildup up dust, debris, snow and ice and to utilize the
"frameless" feature of these modules to best advantage.
Always maximize ventilation behind modules for cooling.
A minimum clearance of 1.5 inches between mounting surface and modules is required to maintain
fire rating.

T &S Job No.: 10500
Subject: Summary Letter for Series 200
INTRODUCTION
This Project Summary Letter is in reference to the Structural Calculation Packet for the
SnapNrack Series 200 Mounting System, dated January 2012. The calculations have been
performed in accordance with the 2010 California Building Code (CBC), the governing
structural code in California, which is based on the 2009 International Building Code (IBC).
The 2009 IBC references the 2005 Minimum Design Loads for Buildings and Other
Structures, including Supplement No. 1, No. 2, and Errata, by the American Society of Civil
Engineers (ASCE), referred to as the ASCE 7 -5. The racking system has been designed to
withstand code prescribed forces due to the racking system's own weight, the weight of the
solar panels, snow loads, seismic loads, and wind forces.
RAIL SPANS
In terms of variable conditions for the racking system, the follow pages contain charts that
can be used to determine maximum spans and spacings based on the solar array's overall
size and tilt angle. This chart is a summary of the following pages which include the
calculations for each component under each condition.

SUMMARY LETTER
SITE- SPECIFIC ANALYSIS
Each possible racking configuration labeled in the following chart has been analyzed and is
summarized within this chart. Because there are many different possible configurations, (2)
two of the common cases have been provided in this report as example calculations. Site
specific racking configurations with calculations producing the overall results shown in the
following charts can be provided upon request.
A site specific analysis may be required if it is found that the location of the solar panel
installation or configuration corresponds to any of the following criteria (but not limited to):
The total pitch of the solar panel (solar panel pitch) is greater than 45 degrees above
the horizontal. Special note should be taken to measure the solar panel pitch from
the horizontal and NOT the grade to be installed on. See note at the end of this
section.
A topographic factor applies to the location. Topographic factors apply, for general
purposes, when the structure is on the upper half of a hill, or on a mesa or bluff, or is
near a large body of water or other flat surfaces such as salt flats, that exceed 5,000
ft. For complete descriptions of topographic factors, please refer to ASCE 7 -05
Section 6.5.7.
The site ground snow load is greater than 50 psf.
The site design wind speed is greater than 120 MPH (3 second gust speed).
A combination of loads and /or site conditions applies that is not addressed in the
attached rail span and foundation charts.
Verify all conditions with the local building official or a registered professional engineer. If
one of more of these factors applies to the project location, please contact Taylor Syfan,
and we will be able to analyze the site conditions and recommend a custom engineered
configuration for each specific site.

SUMMARY LETTER
It is also to be noted that the provided summary charts assume the site is flat (i.e. the
array is NOT installed on a hillside). For sites with a slope, the listed foundation depths will
be required to be increased as per the soils engineer or, if the project does not involve a
soils engineer, SnapNrack's drawing 5200 -D03.
SUMMARY CHARTS AND TOPGRAPHIC FACTORS
The attached pages of this summary contain common array configurations with varying wind
speeds. These charts can be used as a quick reference for looking up array configurations
and foundation requirements based on the site conditions, but it must be noted that for any
site location where a topographic factor is to be applied (e.g. hills, bluffs, water) the
configurations given may not be adequate for the given site. A registered professional
engineer should evaluate the exact topographic conditions for this specific site prior to
construction. (Taylor Syfan may be retained for this evaluation, however they or another
registered professional engineer should evaluate the site).
UNIVERSAL END CLAMP
SnapNrack has also developed a "Universal End Clamp" which is used to connect individual
solar panels to the rails (see SnapNrack's 5200 drawings). These have been developed and
tested by SnapNrack, and they are adequate to resist the maximum uplift and shear forces
generated by code prescribed wind forces when installed as specified. The testing results
may be presented upon request.
FOUNDATION OPTIONS
Pier Foundations: Piers shall be 12" in diameter and shall be the depth required in
the following charts based on wind speed, panel tilt, and snow Toad. Concrete shall
conform to the attached concrete Specifications.
Grade Beam Option: A grade beam may be used in place of the pier foundations.
See SnapNracks drawing S200 D04 for grade beam configuration; Grade beam shall

be a minimum of 12" wide, 18" deep and shall run the width of the array a minimum
of 12" beyond each vertical post. (2) #4 Bars shall be used at BOTH the top and
bottom of the grade beam, one on each side of the vertical pipe. These shall have a
minimum of 3" clear of concrete cover and shall conform to the attached
Specifications and be adjusted for local conditions. Concrete shall conform to the
attached concrete Specifications. Using the Grade Beam option at locations with a
design wind speed of 120 MPH or higher require a site specific analysis.
SITE SPECIFIC ENGINEERING
The results in this packet are structurally adequate for all configurations shown. For certain
projects, site specific engineering may be recommended to help determine a very efficient
custom installation cost. Taylor Syfan may be contacted to provide a site specific analysis
in order to optimize the racking and foundation design which may lead to substantial cost
savings on certain projects that may have unique site conditions and /or scale.
REFERENCES AND LIMITATIONS
Please note that all sizes, material specifications, and weights have been provided and
approved by SnapNrack.
Please see SnapNrack's plans for limits on the bolt parameters. Torque all 5/16" diameter
hardware as specified in SnapNrack's plans (10 -16 ft -lbs for Silver Stainless Steel and 7 -9
ft -lbs for black Stainless Steel). Torque bolts sufficiently to prevent loosening, but do not
damage bolts or threaded parts. Periodic inspection of connections is required.
SnapNrack has also provided estimated soil values used to calculate the size and depths of
the footings (soil type 4 or better, per IBC Table 1806.2). It is the responsibility of
SnapNrack's customer, otherwise known as the contractor or professional solar installer, to
verify with a soils engineer or the building inspector that the site specific soil conditions
match or exceed the estimated values given within this report. It is also the responsibility
