Thanks for choosing Seraphim Photovoltaic Modules (hereafter referred to as

“PV Module”), This Guide is to give information onhow to apply Seraphim PV

modules properly.

Installers must read and understand this Guide prior to installation. For any

questions, please contact our technical department (technic@seraphim-ener-

gy.com) for further information. Installers should follow all safety precautions

described in this Guide as well as local codes when installing a module.

Keep this Guide in a safe place for future reference (care and maintenance)and

in case of sale or disposal of the PV modules.

This document is applicable to the series of PV modules as listed below:

•The PV modules are qualified for application class A, which may be used in

systems operating at greater than50 VDC or 240 W, where generalcontact

access is anticipated. PV modules qualified for safetythrough this part of IEC

61730and IEC 61730-2 and within this application class are considered to meet

the requirements for safety class II.

•The PV modules shall be properly grounded in accordance with the instruc-

tions in this Guide or the requirements of the National Electrical Code.

•Installing PV modules requires specialized skills and knowledge. Installation

should only be performed by qualified personnel, electrical connections requires a

NEC for the USA and CEC for Canada).

•Installers should assume all risks of injury that might occur during installation,

including, but not limited to, the risk of electric shock.

•One single PV module may generate more than 30V DC when exposed to direct

sunlight. Access to a DC voltage of 30V or more is potentially hazardous.

• PV modules convert light energy to DC electrical energy, which are designed for

outdoor use. PV modules can be mounted onto ground, rooftop, vehicles or boats

etc. The proper design of support structures lies within responsibility of the system

designers and installers.

•Do not use mirrors or other magnifiers to concentrate sunlight onto the PV

modules.

the Northern Hemisphere, the module should typically face south, and in the

Southern Hemisphere, the modules should typically face north. The most optimistic

installation angle varies according to different latitudes and longitudes; please con

sult experts with appropriate knowledge background when determining the instal

lation locations and angles.

When choosing a site, avoid trees, buildings or obstructions, which could cast

shadows on the solar photovoltaic modules. Shading causes hotspot and loss of

output, even though the factory fitted bypass diodes of the PV module will mini

mize such effect.

Do not install the PV module near naked flame or flammable materials.

Do not install the PV module in a location where it would be immersed in water or

constantly exposed to water from a sprinkler or fountain etc.

• It is recommended to install the bifacial modules 1m away from the ground or roof

to maintain the energy yield of module rear side.
