1. General Information

The photovoltaic (PV) modules FU XXX M /

MV / P / PV / Next / Next Pro / Silk Pro,

(hereafter “FU XXX” or “FU”) are devices that

produce electrical energy by converting the

sunlight’s radiation reaching their surface,

when appropriately exposed, into

continuous/direct current (DC).

The FU modules are intended to be used in

photovoltaic module systems connected to the

electrical grid. It is also possible to use them in

battery powered photovoltaic module systems

(stand alone).

The rated currents at Standard Test

Conditions (STC) of the FU modules are

variable depending on the model and the

relative power rating, as indicated in the

respective technical data sheets. Most of the

electrical parameters of the modules, specified

in the datasheets, are determinable only by

using special instrumentation in the laboratory;

therefore, only some of them are measurable

outside of a lab, using common

instrumentation (voltmeter, AM meter,

solarimeter/pyranometer).

It is possible, following very precise

procedures, to carry out electrical

measurements of voltage and current as

snapshots, which enable you to monitor the

operation of the modules and determine

possible, although rare, anomalies.

The electrical output parameters for FU

modules, of technical importance during the

operation, installation and maintenance, are

the following:

• Voltage at open circuit (Voc) with

tolerance of ± 4%

• Current at short circuit (Isc) with

tolerance of ± 5%

• Voltage at point of maximum power

(Vmpp)

• Current at point of maximum power

(Impp)

• Power (Pmax) with tolerance of ± 3%

• Solar radiation in W/m2 at the time

• Temperature of the modules

The general performance of the modules is

heavily dependent on the intensity of the

incident solar radiation, as illustrated in Fig.1.

Acheiving maximum performance requires

proper installation, with the modules oriented

towards the South in Northern hemisphere

and their surface exposed as perpendicularly

possible to the incident rays of the sun;

furthermore, avoiding any shading caused by

obstacles in and around the area of

installation.

Fig. 1: IV curve at different irradiance

A high ambient temperature and therefore, an

increased operational temperature of the

modules, also contribute to a proportional

reduction in electrical performance. Please

see fig. 2

Fig. 2: IV curve at different temperatures

In order to optimize the production of electical

energy of the modules, and therefore of the

system connected to an electrical grid, it is the

responsibility of the installer to make sure the

modules are positioned as much as possible

facing North in Southern hemisphere, with the

tilt angle (β) (inclination of the surface of the

modules in respect to the ground, as shown in

Fig.3) optimal for the type of desired

application.

The tilt angle of ideal average throughout

Australia is β = 30°; however, even the

inclination typical the roof of a dwelling (β = 20-

40°), being already an inclined plane, could

make the angle acceptable, if not ideal, for the

installation of coplanar modules on it (using a

special standard structure for support).

Depending on the variation of the tilt angle of

the modules with respect to the ground, or of

their orientation in relation to facing south

(Azimuth), there will be changes in the annual

average amount of energy produced by the

modules themselves, and therefore, of the

plant connected to the network to which they

are linked.

5. Module Specification

Please refer to the technical datasheet for the

module FUTURASUN FU XXX respectively for

electrical performance data. These electrical

data are measured under Standard Test

Conditions (STC) of 1000 W/m2 irradiance,

with Air Mass (AM) of 1.5 spectrum, and a cell

temperature of 25°C.

6. Safety Precautions

Installation should be performed only by

authorized personnel!

• Module installation must be performed in

compliance with the latest IEC code

• Within the modules, there are no user

serviceable parts. Do not attempt to repair

any part of the modules. Contact your

module supplier if maintenance is

necessary

• In order to reduce the risk of electric shock,

prior to installing the modules, remove

metallic jewelry and use insulated tools

during installation.

• Do not expose the modules to artificially

concentrated sunlight!

• Do not stand on, drop, scratch, or allow

objects to fall on the modules.

• Do not lift the modules at the connectors or

junction box!

• Do not install or handle the modules when

they are wet or during periods of high

winds.

• Do not use oil-based lubricants on any part

of the junction box as this can cause long-

term damage to the plastics.

• Ensure that wire cable connections are

routed in accordance with the junction box

manufacturer’s recommendations.

Incorrect routing of the wire cable can lead

to stress damage to the junction box.

• The minimum cable diameter for the

modules intended for field wiring is 4 mm²

• The PV connectors to mate with the

modules should be Renhe 05-6 or

TongLing TL-Cable01 for modules with

maximum rated voltage of 1000 V and

Renhe 05-8 or TongLing TL-Cable01S for

modules with maximum rated voltage of

1500 V.

• The rated voltage of the connector should

be 1500 V and the rated current ≥ 30 A.

• The cross section for the connector is 1 x

4,0 mm².

• Do not leave cable connectors exposed in

adverse climatic conditions. Water and

dust deposits inside the cable connectors

can cause long-term damage.

• Broken module glass, a torn back sheet, a

broken junction box or broken connectors

are electrical safety hazards;

consequently, contact with a damaged

module can cause electric shock.

• Fire ratings: Spread of Flame and Burning

brand Fire Class C (acc. to UL

61730/UL790). Ignitability Test Class E

(acc. to IEC 61730-2).

• The total voltage of modules connected in

series corresponds to the sum of the

voltages of the single modules; whereas

connecting the modules in parallel results

in adding up the currents. Consequently,

strings of inter-connected modules can

produce high voltages and high currents

and constitute an increased risk of electric

shock and may cause injury or death.

• Modules shall not be connected in series

to create strings with a higher voltage than

the maximum system design voltage

and/or the maximum range allowed by the

inverter and/or the safe operational

voltage range of safety

devices/switchgears composing the

system, in the environmental conditions

the system will be installed

• For installation, maintenance, or before

making any electrical connection or

disconnection, ensure all modules in the

PV array are exposed to a light intensity

that is less than 400 W/m2!! If necessary,

the modules should be covered with an

opaque cloth or other material in order to

shield them from exposure to light intensity

greater than 400 W/m2.

7. Installation

7a) Module Mounting

• The FU modules are qualified for an

operative temperature within the range of -

40 to +85 °C.

• The FU modules can be installed at a

maximum operating altitude of ≤ 2000

meters.

• When installing FU modules, local building

code requirements and regulations must

be observed at all times. Sufficient

ventilation of the module backside is

required and the mounting configuration

(e.g. sufficient clearance) should be

adapted accordingly.

• Do not drill any additional holes into the

module frames and do not cover the

drainage holes.

• Pre-assembled mounting systems

must be confirmed by FUTURASUN in

writing in advance

• The modules can be mounted in every

angle from horizontal to vertical, avoiding

configurations with the junction box up-

side down at all times (e.g. trackers with

“sleep mode”).

• In order to maximize module exposure to

direct sunlight, the modules should be

oriented to the south in the northern

hemisphere and to the north in the

southern hemisphere.

Mounting Methods:

Mounting using mounting holes:

• Each module must be securely

fastened at a minimum of 4 points.

• Use the 4 mounting holes (slots, see

Fig. 4 and 10) on the PV module frame

to bolt the module with stainless steel

screws and nuts to the mounting

framework.

• The distance of the mounting holes has

been designed in order to result in a

uniform wind and snow load without

damaging the module.

This document applies to modules FU XXX P / PV / M / MV Next / M / MV Next Pro / M / MV Silk Pro

• Do not drill additional holes in the

module frame; doing so will void the

warranty.

Mounting using clamping method:

• FUTURASUN recommends the use of

clamps.

• When using clamps, it is possible to

mount the modules in horizontal (the

shorter side of one module facing the

shorter side of the neighboring

module) or in vertical (the longer sides

facing each other) configuration. (It is

recommended to always use stainless

steel screws and bolts.)

• The modules can be mounted on

continuous base structures (inclined or

horizontal) such as rails or similar.

• Both base structures must be mounted

at the same distance from the

symmetrical axis (vertical or horizontal)

of the module.

• In vertical configuration, it is strongly

recommended to place the supporting

elements nearby the mounting holes,

or in any case, the distances shown in

Fig. 4 should be respected. This is

necessary in order to maintain a

correct load distribution.

• The FU XXX modules with 60 cells (or

120 half-cut cells) configuration are

qualified to 3600 Pascal (5400

including a safety factor of 1,5) in wind

and snow load when the module is

fixed in the green and yellow area (See

Fig. 3)

• The FU XXX modules of size 72 cells

(or 144 half-cells) are qualified to 2400

Pascal (3600 including a safety factor

of 1,5) in wind and snow load when the

module is fixed in the green and yellow

area (See Fig. 3)

• In accordance with Eurocodes - EN

1991 it is not possible to fix the

modules in yellow area (See Fig. 4) in

Zone 3,4,5 of Alpine Region. Shape

coefficients must be taken into

account.

• In horizontal configuration, fixing the

modules by clamping in the green area

in fig. 4 is certified to retain the

characteristics regarding the static

loads

• When clamping the modules in

horizontal configuration on a support

structure, the distances in Fig. 4 have

to be applied in order to maintain the

resistance against static loads as

certified:

• The modules can also be fixed by

placing them with their frame on a

structure that is supporting the two

sides of the frame over their whole

length. Also in this case, the position of

the mounting clamps must be in

accordance with distances indicated in

Fig. 4.

• At least 20 mm spacing must be

maintain between modules

ATTENTION: in the case of installation with

modules in the vertical position, it is preferable

to maintain the Junction Box located in the

upper part of the module. This practice will

help reduce, as much as possible, contact

between any standing water and the Junction

Box, and avoid possible water infiltration.
