�+" y The SunPower Limited Warranty for PV Modules is contingent upon modules
being mounted in accordance with the requirements described in this "section.
5.1 Site Considerations
SunPower modules should be mounted in locations that meet the following
requirements:
Operating Temperature:. All SunPower AC modules must be mounted in
Y' r • environments that ensure SunPower modules will operate within the following
T maximum and minimum operating temperatures:
Certain operating environments are not recommended for SunPower AC modules;
and are excluded from the SunPower Limited Warranty, of these modules. Request.
your supplier. to contact SunPower if there are any unanswered questions
concerning the operating environment.
5.2 Mounting Configurotions
Modules may be mounted at any angle; from horizontal to vertical. Select the,
appropriate orientation to maximize sunlight exposure. Specific information on
module dimensions and the location of mounting holes is shown in Fig. 2.'

In order to prevent water from entering the junction. box (which could present a
safetyhazard), modules should be oriented with the junctionbox in the uppermost
position and should not be mounted such that the top surface faces downward

Procedure for determining bill of materials
The tool estimates the bill of materials needed for the array based on the array layout provided by the
user, the selected spacing of attachments, and the user's indication of which modules ace located in'which ,
wind zones of the building roof.
For the purpose of estimating the number of attachments in a bill of materials, if any portion of a module ,
is located:in roof wind zone 2 or 3, the tool assumes that the attachment spacing for that entire module
corresponds to the worst case wind zone. This is a conservative assumption in orderto simplify the user
interface of the tool and to avoid underestimating the number of required parts.'For the final design of the
array, you as the Registered Design Professional may choose to do, more-, specific calculations, to
determine whether fewer, attachments can be used. For example,'in the case of a module where only one.
rail (and half or less of the module area) is in zone 2, with the remainder of the module in zone 1, it may _
be appropriate to use zone 2 attachment spacing for the raii'iri zone.2,-and zone 7 spacing for the rail in
` zone 1. In this case, the user can override the quantity of attachments in the bill of.maierials if desired.

3. Assumptions for use ?
To streamline the use of the 'tool, the tool includes assumptions that are appropriate for normal
applications of Invisimount. Assumptions include the following:
• The building is assigned to Risk Category, II per ASCE 7-10 Table 1.5-1. Risk Category H covers
most residential buildings.
• No live load acts on the panels. '
• The wind directionality -factor Ke =, 0.85 per ASCE 7-10 Table 26.6-1.
• ASCE 7-10' Figure 30.4-2A, 30.4-213, or 30.4-2C is applicable for determining roof wind zones and
external pressure coefficient GC, for solar the arrays. For one of these figures to be applicable, the
height h must be less than or equal to 60 ft, and the building must be either a gable roof with slope
less than or equal to 7 degrees, a gable/hip roof with slope 8 to 27 degrees, or a gable roof with slope
28 to 45 degrees.'.See ASCE 7=10 Section 30.4 for details. '
• For wind on solar arrays; the internal pressure coefficient GC,; = 0 per ASCE 7-10 Table 26.11-1.
•_ For snow loads, the thermal factor Cr = 1.2 for the array per ASCE 740 Table 7-3. This applies to
"unheated and open air structures" and is assumed to be appropriate for solar arrays that are separated '
from the roof.
• For snow loads, the exposure factor C, = 0.9 for the array per ASCE 7-10 Table 7-2. This applies to
roofs that are "fully exposed," meaning, that there are no obstructions 'such as "terrain, higher '
structures, or trees,"'parapets, or other rooftop equipment of a height and proximity that would cause
increased snow buildup on the array. The' `fully exposed" assumption may not be appropriate for
s situations where obstructions are'located "within a distance of 10h" of the roof, "where ho is the
heightof the obstruction above the roof level. If the only obstructions are a few deciduous trees that are leafless in winter, the `fully exposed' category" is appropriate (ASCE 7-10p. 30). See ASCE 7-10
Table 7-2 for details. .
• For snow loads, the slope factor C, for the array per ASCE 7-10 Figure 7-2 is calculated assuming the
array is an "unobstructed 'slippery surface" that will -allow snow to slideoff the eaves. This
assumption may not be appropriate for cases -where snow is prevented'from sliding off the array
because of valleys in the roof, for example. See'ASCE 7-10 Section 7.4.
• For seismic loads, Site Class = D'per ASCE 7-10 Section 11.4.2:' See ASCE 7-10 Section •11.4 for ,.
details and other site conditions. `
• The'seismic component importance factor Ip = 1.0 for the solar array per ASCE 7-10 Section 13.1.3.
• For seismic loads, the component :response modification factor RP = 1.5, -'and the component ,
amplification factor ap = 1.0; per ASCE 7-10 Table 13.5-1 or 13.6-1. This assumption is consistent
with recommendations for other types of rooftop solar arrays in the guideline SEAOC PVl Structural- t
