Purpose of this guide

This guide contains information regarding the installation and safe handling of Sunrise Solartech

Co., Ltd photovoltaic module (hereafter is referred to as “module”). Sunrise Solartech Co., Ltd

hereafter is referred to as “Sunrise”.

Installers must read and understand the guide before installation. Any questions, please contact our

sales department for further explanations. The installer should conform to all safety precautions in

the guide and local codes when installing a module.

Before installing a solar photovoltaic system, installers should become familiar with the

mechanical and electrical requirement for such a system. Keep this guide in a safe place for future

reference (care and maintenance) and in case of sale or disposal of the modules.

General

Installing solar photovoltaic systems may require specialized skills and knowledge. Installation

should be performed only by qualified persons.

Each module comes with a permanently attached junction. Sunrise can provide customers with

fitted cables for ease of installation if desired.

Installers should assume the risk of all injury that might occur during installation, including,

without limitation, the risk of electric shock.

One individual module may generate DC voltages greater than 30 volts when exposed to direct

sunlight. Contact with a DC voltage of 30V or more is potentially hazardous.

Do not disconnect under load.

Photovoltaic solar modules change light energy to direct-current electrical energy. They are

designed for outdoor use. Modules may be ground mounted, mounted on rooftops, vehicles or

boats. Proper design of support structures is responsibility of the system designers and installers.

Use of mounting holes is suggested in a following paragraph.

Do not attempt to disassemble the modules, and do not remove any attached nameplates or

components from the modules.

D

o not apply paint or adhesive to module top surface.

Do not use mirrors or other magnifiers to artificially concentrate sunlight on the modules. Do not

expose back sheet foils directly to sunlight.

Installation Guide 2011 2/10 www.srsolartech.cn

When installing the system, abide with all local, regional and national statutory regulations.

Obtain a building permit where necessary.

Safety precaution for installing a solar photovoltaic system

Solar modules produce electrical energy when light shines on their front surface. The DC voltage

may exceed 30V. If modules are connected in series, the total voltage is equal to the sum of the

individual module voltages. If modules are connected in parallel, the total current is equal to the

sum of individual module currents.

Keep children well away from the system while transporting and installing mechanical and

electrical components.

Completely cover the module with an opaque material during installation to keep electricity from

being generated.

Do not wear metallic rings, watchbands, ear, nose, lip rings or other metallic devices while

installing or troubleshooting photovoltaic systems.

Use only

insulated tools that are approved for working on electrical installations.

Abide with the safety regulations for all other components used in the system, including wiring

and cables, connectors, charging regulators, inverters, storage batteries and rechargeable batteries,

etc.

Use only equipment, connectors, wiring and support frames suitable for a solar electric system.

Always use the same type of module within a particular photovoltaic system.

The electrical characteristics are within ±10 percent of the indicated values of Isc, Voc, and

Pmax under standard test conditions (irradiance of 100mW/cm2, AM 1.5 spectrums, and a cell

temperature of 25°C (77°F))

Under normal outdoor conditions the module will produce current and voltages that are different

than those listed in the date sheet. Data sheet values are values expected at standard test conditions.

Accordingly, during system design, values of short-circuit current and open-circuit voltage should

be multiplied by a factor of 1.25 when determining component voltage ratings, conductor

ampacity, fuse ratings and size of controls connected to the modules or system output.

Product identification

Each module has three labels on its rear side providing the following information:

Nameplate: describes the product type; rated power, rated current, rated voltage, open circuit

voltage, short circuit current, all as measured under standard test conditions; weight, dimension

etc.; the maximum system voltage 1000 volts DC and is shown on the nameplate. Maximum fuse
