General Installation Manual
© January 21, 2009. SANYO Energy (USA) Corp. All Rights Reserved.
USE cable, rated sunlight resistant, for modules and interconnect wiring that is exposed to weather.
•Observe the requirements described in sections labeled INSTALLTION and SPECIFICATIONS.
INSTALLATION
Please read this guide completely before installation or use of the PV modules. This section contains electrical and mechanical specifications needed before use.
•Modules should be firmly fixed in place in a manner suitable to withstand all expected loads, including wind and snow loads.
•Metals used in locations exposed to moisture shall not be employed alone or in combinations that could result in deterioration or corrosion.
•Install modules where they are not shaded by obstacles like buildings and trees. Especially pay attention to avoid partially shading modules by objects during the daytime.
•Contact an Authorized Representative with questions regarding mounting profiles for modules if needed.
Notes on Installation
•Clearance between the roof surface and module frame is required to allow cooling air to circulate around the back of the module. This also allows any condensation or moisture to dissipate. Install modules so that air can circulate between the roof and the module.
•Leave 4 inches of clearance between the roof and the module frame.
•SANYO recommends the installation method and mounting profile shown in Figure 1.
•A module should be attached on a mount or support structure rail by metal clamps. The metal clamp must fulfill the following specifications:
Size: not less than 1.5” (38mm) width Thickness: not less than 0.12” (3mm) Material: aluminum alloy
•Recommendation of bolt torque range: 16N.m to 20N.m.
Operating Conditions
SANYO requires that modules be operated within the following conditions:
•Modules are intended for use in terrestrial applications only—no outer space use.
•Modules must not be installed nor operated in areas where, salt, hail, snow, sand, dust, air pollution, chemically active vapors, acid rain, soot, etc., are excessive.
• |
The ambient temperature must be |
multiplying factor of 1.25 which may |
|
within –20°C (-4°F) to 46°C (115°F). |
be applicable. |
|
The temperature limits are defined as • |

SPECIFICATIONS
•Rated electrical characteristics are within –5% to +10% of the values measured at Standard Test Conditions
(STC). STC conditions are; Irradiance of 1000W/m2, 25oC cell temp., solar spectral irradiance per IEC 60904-3.
•Under normal conditions, a photovoltaic module may experience conditions that produce more current and/or voltage than reported at Standard Test Conditions. Accordingly, the values of Isc and Voc marked on UL listed modules should be multiplied by a factor of 1.25 when determining voltage ratings, conductor capacities, fuse sizes, and size of controls connected to the module output. Refer to Section 690 of the National Electrical Code for an additional
Mechanical Loading
•Modules should be mounted at four (4) symmetrical quarter points by the means shown in Figures 1 and 2.
•This method offers a maximum load of 2,880N/m2 (60PSF) in a static state on the module surface. Note: This 60PSF mechanical loading value was tested
with the following mounting devices: SolarMount® by UniRac®; top mounting clamps; mid clamp and end clamp size F; part no. 320029, 320102.
WIRING
•All wiring should be done in accordance with applicable electrical codes.
