DANGER!

Electric shock

The connection of two or more modules in series results in the accumulation of 

voltage and imposes danger. Do not insert electrically conductive parts into con-

nectors! Do not attach solar modules and wiring with wet connectors! Make 

sure to work with dry tools and under dry working conditions!

Work on live parts

When working on wiring, use and wear protective equipment (insulated tools, 

insulated gloves, etc.)!

ATTENTION

Do not use damaged modules. Do not dismantle modules. Do not remove any 

parts or nameplates fitted by the manufacturer. Do not apply paint or adhesives 

to the module, nor work on it with sharp objects.

WARNING!

Arcing

Modules generate direct current (DC) when exposed to light. When breaking a 

closed circuit, a dangerous arc may be generated. Do not cut any live wires. 

Safe installation

Do not carry out installation work in strong winds. Secure yourself and other 

persons against falling. Secure work materials against dropping. Ensure a safe 

working environment so as to prevent accidents. 

Fire protection/explosion protection

Modules must not be installed in the vicinity of highly flammable gases, vapors 

or dusts (e.g. filling stations, gas tanks, paint spraying equipment). The safety 

instructions for other system components must also be followed. Make sure to 

comply with local standards, building regulations and accident prevention regu-

lations during installation. For roof installation, modules must be mounted on a 

fire-resistant roof covering rated for the application. 

Unpacking and intermediate storage

Do not use the junction box as a handle. Do not place modules roughly on hard floor 

or on their corners. Do not place modules on top of each other. Do not step or stand 

on modules. Do not place any objects on modules. Store modules in a dry place. 

Grounding of module and frame

We recommend ensuring the functional grounding of the module metal frame. If 

an exterior lightning protection system is already provided, the PV system has to 

be integrated into the protection concept against direct lightning stroke. Local stan-

dards shall be observed.

through the requirements in UL 1703, may be used for grounding connections in 

accordance with the instructions provided with the module. The electrical charac-

teristics are within ±10 percent of the indicated values of ISC, VOC, and Pmax under 

standard test conditions (irradiance of 1000 W/m², AM 1.5 spectrum, and a cell tem-

perature of 25°C (77°F)). Under normal conditions, a photovoltaic module is likely to 

experience conditions that produce more current and/or voltage than reported at 

standard test conditions. The requirements of the National Electrical Code (NEC) in 

Article 690 section II shall be followed to address these increased outputs. In Canada 

the installation shall be in accordance with CSA C22.1, Safety Standard for Electrical 

Installations, Canadian Electrical Code, Part 1.

Suitable ambient conditions

Artificially concentrated sunlight shall not be directed on the module or panel. The 

module must neither be immersed in water nor be exposed to continuous spraying 

(e.g. by fountains). Exposure to salt or sulfur (sulfur sources, volcanoes) implies a risk 

of corrosion. The module must not be used for maritime (e.g. boats) or automoti-

ve (vehicles, trailers, etc.) purposes. The module must not be exposed to extraordi-

nary chemical loads (e.g. emissions from manufacturing plants). If the modules are 

installed on stables, a distance of 3.28 ft (1 m) to ventilation openings shall be ensu-

red; the modules shall not be used as a direct roof panel on stables.

Appropriate installation situation

Make sure that the module meets the technical requirements of the overall system. 

Other system components should not exert any adverse mechanical or electrical 

influences on the module. Modules may bend under high loads. For this reason, 

sharp-edged fixing elements or other sharp objects (e.g. cable ties on mounting sec-

tions) must not be mounted near the module back side. When using a string inverter, 

for modules connected in series, only modules of the same amperage rating may be 

used together. For modules connected in parallel, modules with the same voltage 

ranges must be used together. The modules must not be operated at a higher volta-

ge than the permissible system voltage. The frame corner element is intended for 

water drainage and must not be blocked. For system documentation, please note 

the serial numbers.

Optimum installation

In order to avoid performance losses, all modules connected in series should be 

arranged with the same orientation and tilt angle. The modules should be installed 

in an all-season shadow-free area. Even partial shadowing results in yield losses and 

is to be avoided. Ventilation of the module back side will prevent heat build-up adver-

sely affecting performance.

Mounting

The modules must be securely fixed at a minimum of 4 locations on the substructu-

re. Fixing is only allowed in designated areas. When using “Top-Down” clamps use 

high-quality extruded aluminum or stainless steel clamps or stamped stainless steel 

clamps. Insure that the mounting system and clamps meet the design requirements 

of the system.  In regards to “Top-Down” mounting methods, the maximum clam-

ping pressure is 50 N/mm² (15 ft-lb).

Do not use formed (bent) clamps!  Do not drill any holes into the module. Use corro-

sion-proof fixing material.

For bottom-mounting hardware use 8 to 9mm (1/4" or 5/16") diameter bolts that are 

less than 25 mm (1") in length.  The head of the bolt must face the module backsheet.  

Torque specifications are set by the system engineer.

Electrical connection

The modules are provided with factory-assembled cables and connectors . Do not 

open the junction box in any case. Connectors may only be connected under dry con-

ditions. Make sure to avoid gaps in a plugged connection. Only solar cables with an 

adequate cross-section (2.5 mm² or 14 AWG minimum) and appropriate connectors 

may be used for connecting the modules. Cables should be attached to the installa-

tion system by means of UV-resistant cable ties. Exposed cables should be protected 

against sunlight and damage by suitable precautions. Check that wiring is correct 

(polarity!) prior to starting the inverter.

SolarWorld Sunmodules are equipped with Amphenol UTX H4 connectors; connect 

ONLY Amphenol Helios H4 or Amphenol UTX H4 connectors with the module. 

Cleaning

In general, the modules do not need any cleaning if the tilt angle is sufficient  

(> 15°; self-cleaning by rain). In case of heavy soiling, we recommend cleaning the 

modules with plenty of water (tap water or deionized water) without any cleaning 

agents. If necessary, a soft cleaning device (e. g. sponge, soft brush with split bristles) 

maybe be used. In case of soiling by dust or sand the modules can be cleaned with a 

soft brush without using water. Never scrape or rub off dirt; this may result in micro-

scratches.

 

Maintenance

We recommend regular inspections of the system to ensure that:

1.  All fixtures are securely tightened and corrosion-free;

2. Wiring is securely connected, properly arranged and free of corrosion;

3. Cables are free of damage;

Please also observe applicable standards. 

Disclaimer of liability

SolarWorld does not guarantee the operational capability and functionality of modu-

les if the instructions contained in the present user information are not complied 

with. Since compliance with these instructions and the conditions and methods 

of installation, operation, use and maintenance of the modules are not checked or 

monitored by SolarWorld, SolarWorld accepts no liability for damage arising through 

improper use or incorrect installation, operation, use or maintenance. Furthermore, 

liability for infringements of patent law or of other third party rights arising from the 

use of the modules is excluded unless we are automatically liable by law.

General Information

This module is rated for use in application class A according to IEC 61730. For the elec-

trical ratings please refer to the datasheet. Under normal conditions, a photovoltaic 

module is likely to experience conditions that produce more current and/or voltage 

than reported at standard test conditions. Accordingly, the values of ISC and VOC 

marked on this module should be multiplied by a factor of 1,25 when determining 

component voltage ratings, conductor current ratings, fuse sizes, and size of controls 

connected to the PV output.

Specific Information (U.S. and Canada)

The fire rating of this module is valid only when mounted in the manner specified 

in the mechanical mounting instructions. The module is considered to be in comp-

liance with UL 1703 only when the module is mounted in the manner specified by the 

mounting instructions below. A module with exposed conductive parts is considered 

to be in compliance with UL 1703 only when it is electrically grounded in accordance 

with the instructions presented below and the requirements of the National Electri-

cal Code. Where common grounding hardware (nuts, bolts, star washers, spilt-ring 

lock washers, flat washers and the like) is used to attach a listed grounding/bonding 

device, the attachment must be made in conformance with the grounding device 

manufacturer’s instructions. Common hardware items such as nuts, bolts, star was-

hers, lock washers and the like have not been evaluated for electrical conductivity 

or for use as grounding devices and should be used only for maintaining mechani-

cal connections and holding electrical grounding devices in the proper position for 

electrical conductivity. Such devices, where supplied with the module and evaluated 

Grounding in the US and Canada

The modules can be connected at the holes provided in the flange. The lug must be 

a tin-coated copper lug, silver in color. Do NOT use a bare copper lug, which is brown. 

Any grounding method and components listed according to NEC requirements are 

also acceptable in the US and Canada.
